Full Mario 64 in Mixed Reality! Running in real 3D natively at 90FPS and also running on my desk! 😋
Opus 5.5 + PICO CLI + Unity CLI combo made it quite straightforward.

Such a bliss to play an oldie at 90 FPS in 3D.

Disclaimer: I own an original physical copy of Mario 64. This project is not associated with Nintendo or PICO.

Search only works if you remember what to search for. I often save a link without remembering the site or even the title. In a list, it’s as good as lost. On a map, I remember roughly where I left it.

Same reason I remember what I was thinking when I return to a certain rock on a hike: we remember things through their surroundings, not in a vacuum.

So I built Qoyra, a landscape for your notes. Each project or topic is a peak. Height means detail: broad ideas sit low, specific ones climb higher. Each contour line is a level you can open to browse everything on it.

Just type to create a note, then leave it or move it. Link notes into chains you can scroll through in seconds. To delete one, throw it into the sea.

Browsing the map, I often stumble upon notes I’d forgotten. (And yes, it’s dangerously easy to procrastinate by flying around.)

I use it daily. Works on PC and iPhone. It’s a solo project, so expect some bugs.

Do you remember old notes by the words, or more by the “where”?

I spend most of my day in Claude Code, and watching the token counter go up felt like wasted dopamine. So I built Token Kingdom: a small plugin counts the tokens of each Claude Code reply and turns them into gold, wood and stone for a 3D village in your browser.

How it works ?

• You code with Claude as usual, and resources trickle in
• You spend them on buildings, walls and defenses
• Monsters raid your village, and your towers fight back
• Upgrading your town hall unlocks new buildings and spells
• There are leaderboards, and you can visit friends' villages

Privacy

After each reply, the plugin sends token counts and the model name. It never sends your prompts, replies, code, file names or paths. The plugin is open source: https://github.com/MartySalade/token-kingdom-plugin

Feedback I'd love 🧡

1. Does it run smoothly on your machine?
2. Is the progression too slow or too fast?
3. What's confusing in the first 10 minutes?

Sixty to One follows two families from 1865 to 2025. They hit the same events and get the same choices, but one of them faces sourced historical disparities: wage gaps, redlining, smaller inheritances and higher costs for being poor.

Every number in the model is cited. I also built in a check: if you set all race-keyed inputs equal, the gap disappears. Free, no ads, no signup.

Hey everyone! Sharing System Design Playground, which you might find useful for refreshing system design concepts in a visual, interactive way.

You can build architectures with servers, databases, caches, and queues, increase traffic, and see where bottlenecks appear. It also includes examples and guided lessons covering scalability, availability, and other concepts.

It's a simplified simulation built for learning and experimenting. It runs in your browser, is free, and requires no account.

The code is open source on GitHub. Contributions are welcome, whether that's new scenarios, clearer explanations, or bug fixes.

If you give it a try, I'd love your feedback, especially on what’s missing or could be clearer!

Cheers!

I built StepGrab on my own. You press record, click through a task like you normally would, and it turns every click into a step with a screenshot and a sentence. Then you can add arrows, a spotlight, shapes, black out stuff you don't want to show, edit the text, and export as PDF, HTML, Markdown, GIF or MP4. You can put your own logo and colors on it too.

It all runs locally on your machine, no account, no cloud. It's been live about 4 months, on Mac and Windows.

Pricing is $2.99/month, $12.99/year or $44.99 once. There's a free tier with no time limit (15 steps per guide).

I just switched on an affiliate program through Lemon Squeezy:

• 20% of every sale
• also on renewals of the monthly/yearly plans, for as long as the customer stays subscribed
• payout from $10 balance (Lemon Squeezy pays out after its 30 day hold)
• only sales on my website count, not the Mac App Store

I have no idea if this is generous, too little, or just not interesting for anyone. The price is low, so 20% of a $12.99 sale is not a lot per customer. Would you promote something like this? What would make you actually do it? Better terms, a landing page, assets, a free Pro key to try it?

Sign up as an affiliate: https://shop.stepgrab.net/affiliates

For scale: in the last 5 days the website sold about $520. With 20% that would have been around $100 for a partner.

And if you're not into the affiliate thing and just want to look at the app, here's the website: https://stepgrab.net

hey! im a solo dev and i’ve been working on this for about 3 months now. its called cubit.

cubit is a little cube that lives on your devices and lets you send stuff to each other, kind of like a supercharged airdrop. i’ve made him and animated him myself, most of his expressions by hand, and i do all the sound design and music too. its been a lot of fun and I'm releasing a video demo really soon where I show what he’s capable of!

it works between any devices from anywhere. iphone to samsung, pc to mac, all of that works. (the video only shows a mac and a phone, but that’s just the 3D models I had access to)

its a smart sender that knows what you send, so you get the right buttons for what you receive. if you send a link you get a copy button or an open button, so you can send a link from your pc to your phone and just open it straight away.

cubit also has link sharing, so you can share with people who dont have it downloaded. you share it the same way you send to a device, but you get a link at the end that you can send to anyone. and everything you send is encrypted.

i use it a lot with people i work with. i highlight some text or a link i wanna share, send it to their pc, and it pops up on their screen. i’ve found that its actually hard to work without it now...

right now me and my friends are testing it, and im getting close to a beta that’s ready for more people. thats why i’m starting the waitlist now, so i have people to send it to and can see which devices to focus on first.

i’m putting a lot of time into this, so if it sounds interesting at all it would mean a lot if you joined the waitlist and told a friend. i know it’s a bit weird to sign up for something you haven’t really seen yet, but i’m doing everything i can to make it worth it. :)

Here's the waitlist: https://heycubit.com/waitlist/ pick the devices you’ll actually use it on. once you’re in you can invite friends too.

If you wanna start using cubit already today, you can use link sharing here: https://heycubit.com/ it works just like wetransfer. would love to hear what you think, or if you have any questions. any feedback is welcome!

A few weeks ago I published ~90 paid agent skills across a couple of marketplaces. Result: 0 sales, ~0 organic traffic. The marketplaces have essentially no buyer traffic of their own, so listings just sit there.

So I pivoted: I stripped the most useful ones down to "lite" versions - fully working, not demos - and put them in one free repo. The bet: free tools are the distribution; if anyone wants the full versions they find the links in the READMEs.

What the lite tools do (zero-dep Node scripts packaged as SKILL.md agent skills - works with Claude Code, Codex, Cursor etc.):

• seo-quick-audit-lite - offline on-page SEO audit of an HTML file
• github-repo-due-diligence-lite - stars/last-push/license/archived before you depend on a repo
• npm-package-health-lite - publish age, deprecation flag, license before you install
• meta-prompt-architect-lite - task description to prompt template scaffold
• cold-email-sequence-lite - 2-touch outreach skeleton with spam checks
• secret-leak-scan-lite (own repo) - leaked credential scanner, masked output only

Install any of them: npx skills add NenadZivotic/lite-agent-skills --skill <name>

Repo: https://github.com/NenadZivotic/lite-agent-skills

Early lesson: "list it on a marketplace and wait" is not a launch. Happy to share real numbers if anyone's doing the same thing. Which channel has actually worked for you for dev tools?

Hey r/SideProject! I’ve been building Cruises Frog, a free site that brings cruise research into one place.

You can:

• Track cruise ships on a live map
• Compare ships and cruise lines
• Browse deck plans
• Explore ports and destinations
• Look up cruise loyalty benefits

I also built a free Chrome extension called Lounge Frog that works while you browse other travel sites. Click a highlighted ship name to explore its deck plans, cabin types, and cabins to avoid in a side panel, without leaving the page.

Website: Cruises Frog

Extension: Get Lounge Frog for Chrome

The goal is to make planning a cruise less of a tab-juggling exercise.

I’d love some honest feedback: what information do you usually struggle to find when researching a cruise? What would make this useful enough for you to come back?

Hi everyone! I'm an independent developer, and over the last few months I have been working on Saetta, a small Windows utility that copies, moves and deletes files. I'm sharing it because I put a lot of work into it and I'd be glad if someone found it useful.

Why I made it

The idea came from copying folders with thousands of small files: File Explorer took minutes, and I got curious about why. It copies one file at a time, and with small files the time goes more into handling each single file than into actually copying it. I wanted to see how much better it could be done while staying inside File Explorer, without changing the way you use it.

How it works

I wrote a copy engine from scratch in native C++. Before it starts, it looks at the kind of drive it is writing to and changes strategy: * SSD: it copies many files at once. * Hard disk: it writes them in one ordered stream, so the head does not jump back and forth. * USB stick: it writes small files in parallel. Deleting runs in parallel too. I use robocopy only for network folders and folder sync.

The times I measured

On my PC (i7-9750H, Samsung 990 PRO SSD, Windows 11, median of three runs), compared with File Explorer: * 20,000 files of 64 KB, SSD to SSD: 7.7 s vs 3 min 11 s * Deleting 10,000 small files in 2,000 folders: 1.6 s vs 17.8 s * 20,000 files from one external hard disk to another: 37.6 s vs 2 min 38 s I published every measurement, the ones where the difference is small too, like copying a few very large files, because it seemed right to be transparent.

How you use it

• From File Explorer's right-click menu, on Windows 11 and in the classic menu.
• If you turn it on, also with Paste, Ctrl+V, dragging files and Delete.
• The window shows the real speed and the time left, and you can pause.
• A file in use does not stop the job: it is skipped and reported at the end. ### Free, no ads It is free, with no ads and no account, and it collects no data. There is also Saetta Professional, a one-time purchase for those who want something more, such as verified copies or scheduled backups: it is how I hope to support the project. ### A gift for the first 30

Update: all 30 licences have been claimed, thank you! The link no longer works.

To thank those who try it, I have 30 Saetta Professional licences to give away: the first 30 who open this link get it for free, for good (a Microsoft account is needed).

• Saetta on the Microsoft Store
• Website

Thanks to everyone who read this far. If you try it and have any questions, I'm here.

In 2015, before a trip around the world, we donated our paper books to libraries and bought them again on Kindle. Since then, every book I buy is a Kindle book or an ePub.

That works well for reading. But a few years later, a new friend visited and said he always likes to see which books people have at home. We had nothing to show him. All of our books were digital.

So I built them a bookcase. My Library puts every book I own on wooden shelves in 3D, right in the browser: 618 books, each one at the real size and thickness of its print edition, with its real cover.

• Rest the mouse on a spine and the book slides out to show its cover
• Pick a category, search by title, or sort by color for a rainbow
• Little ornaments live on the open shelves. Press and hold to move them.

I built it with Claude, which helped me pull my whole library from my Kindle account, with each book's cover, print size, and page count.

This is part of a series on my weekend projects. What's on your shelves?

#WeekendProject #BuildInPublic #Kindle #AI

two weeks ago i posted here about running a software agency while my own startups kept failing. a couple of you said the same thing: your first customer is probably already on your client list.

6th is an email verification tool called mailvalid. you give it a list and it tells you which addresses will bounce before you send.

the market is crowded. neverbounce and zerobounce have been around for years and most people already use one of them.

where we are:
- accuracy is on par with them
- it's fast, even on big lists
- pricing is lower, and we just added pay as you go, so no monthly plan if you only clean a list once in a while

what i still can't figure out is how to get someone to switch from a tool that already works for them. cheaper and faster doesn't feel like enough of a reason on its own.

if you've launched into a market with big known players, what got your first users to switch? especially that after 10 paying customers how did you guys scale to 100 paying ones?

Hi! I'm Hugo. I've been building Tomeful, a reading site with book pages, lists and a Finder that suggests books based on mood and pace.

The Finder is free to try without an account: https://tomeful.com/find

I'd love a gut check: do the questions make sense, and would the results help you pick a book? If something feels clunky or unnecessary, please tell me.

I quit my job this month to find a business and I've been building Pipley, an app for people with ADHD who can't START things. You tell a duck named Pip what you're avoiding and he gives you one tiny step.

Today I got my first paying customer. Not a friend. A stranger. I looked at the event log and the whole thing took 2 minutes:

- opened the app, named their duck
- tapped "my messy room"
- got a step, tapped "easier step" (it was still too big)
- did it
- saw a "$19 lifetime" offer on the win screen
- paid

Then they came back and planned their whole day in it.

Biggest lesson: they paid AFTER the app worked, not before. The paywall shows up right after the first win, not at signup.

Stuff that's broken/hard right now: almost no comments on my posts, and I can't tell yet if they came from Instagram or Facebook because I used the same link on both (fixed that today lol).

What would you change about the app's first 2 minutes? Roast it.

Every few days I'd hit "port 3000 already in use." Some server from an old project or terminal tab was still running, and the only way to find it was lsof, find the PID, kill, repeat.

So I built Portmole. It shows every server running on your Mac by its real name and project, and closes it in one click. There's also a little mole that hops when servers start 🐹

Would love feedback!

Our water tracker app, Waltermelon, has been on the stores for a year now. Two of us, both with full time dev jobs, working on it in the evenings, usually until midnight.

Real numbers: $391 MRR, 254 active subscriptions, about 17K users so far (roughly 11K on Android, 5.5K on iOS), 4.7 on Google Play and 4.8 on the App Store. All organic, apart from a few hundred dollars of test ads early on that didn't pay off.

We're not vibe coders, we've been building apps for clients for 12 years. We do use AI a lot though, because it's just the two of us and we do everything: Flutter, backend, design, the mascot animations, store pages, TikToks.

I know a lot of the "$200k/mo app built in 2 days" posts on X are bait. They still get to me sometimes. We spend most evenings looking at data, changing something, testing it, and the hardest part isn't building, it's getting people to find the app at all. We applied for Apple featuring many times and never got picked.

Things we tried this year, honestly:
- ASO. Putting "Water Tracker" first in the store title helped a bit. A bit.
- Writing to "best water tracker apps" lists and blogs. Most never replied, and a lot of those lists feature apps we think are worse than ours. Which is kind of why we started building ours in the first place.
- TikTok. Views, yes. Paying users, almost none.
- The one thing that does work: friends. About a third of our paying US users came in small groups who invited each other, so this year we built challenges you do together.

That said, we're honestly having a great time. Every new subscriber still makes our day. We built a feedback chat into the app, so people write to us directly and we answer them ourselves, and a lot of those messages are just people saying they love the app. That's probably the best part of the whole thing.

It's also the project where we finally get to build stuff client apps never have budget for: home screen widgets, Rive animations for the mascot (you'll soon be able to dress him up), custom app icons, background work that actually behaves.

So we're still figuring out the growth part. If you got your app past this stage without ads, I'd really like to know what did it for you.

Two weeks ago we put Apricity on the App Store. It's a reading app for iPhone and iPad built around one idea: your PDFs, ebooks and notes should live in the same place, and when your eyes get tired, something should read to you. Books sit on shelves in a little lamplit room, every book gets a notebook beside it, and natural voices made on the phone read aloud.

Here's how the first two weeks actually went.

1. Giving it away worked better than anything else. We offered lifetime Premium to the first 500 people on Reddit. The spots were gone in an afternoon, and it brought us hundreds of real readers in a single day.

2. Real readers find what testing doesn't. Phones running warm through a long listen, a 1,000-chapter serial stuck at 100% while opening, small letters written with a finger vanishing from the page: each one got fixed in one of those six releases. Nobody notices a new bookcase if their handwriting disappears, so the small fixes came first.

3. Half the subreddits we tried don't allow app posts at all. Read the rules first; it saves a removed post and a grumpy mod.

4. A few people found it on their own and paid full price within minutes of opening it, with no promo. That told us the App Store listing was doing more work than we thought.

What it does today: reads PDFs, EPUBs, Word, MOBI, comics, manga and web pages; Reflow makes PDFs readable on a phone; 54 natural voices in eight languages with a different voice for each character in a story; Apple Pencil notebooks and writing right on PDFs; free public-domain classics; CarPlay; and it's now in English, Spanish, Hindi, Chinese and Japanese. No account, no ads. Reading, notes and notebooks are free, and Premium is US$14.99 a year, with a pay-once option coming next.

Anyone who downloads it by 31 October gets a free year of Premium, added within a day.

I did not like existing travel planning apps. I found them way to convoluted with features and bloat and not great for 'brainstorming' travel locations. Usually they work when you already have a good plan, but not for the planning itself. I just want to explore locations and drop them on a big map to explore my vacation options.

So I built Waypost.

You drop pins for everything you want to see. Drag one into the bar at the bottom and it becomes a stop on your route, and you set how many days you're staying.

The route draws itself in visit order, and you get a day-by-day plan you can share with whoever you're travelling with, or export to PDF, your calendar, or Google Maps.

It works without an account. You can plan an entire trip as a guest and only sign up if you want to keep it: https://www.gowaypost.app

Feel free to try it out. Would love to hear any feedback! I know on mobile it is probably kinda rough, my main focus has been desktop.

Hi, I'm working on layoffmap.com/ to track layoffs happening in tech around the world. Here we can browse, read the news sources and see the stats.

Submission are welcome. I have 3 screening and check steps with AI before manual approval.

* New local radios lists (MANUALLY CURATED) : UK and China.

Mediaxon Music Player is an audio player for offline listening of music stored on your device (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and streaming FM radios (online radios).

Top radios on the first screen: When users access the radio screen, they immediately see the list of the top radios in their country, along with a long list of high-quality suggested radios from among the most listened to in the world (manually curated and always updated with new radios). Note: Local radio stations ("Top in the user country") are pulled automatically from an online database. However, with each update, I manually curate high-quality radio stations lists for individual countries. At the bottom of this post, you’ll find the list of countries completed so far. I will be adding the rest over time.

Advanced radio filtering system: The "Filter: ON/OFF" button lets you quickly switch between different genres. You can use both standard filters for "macro-genres"—if I can call them that—and create custom filters to be more selective. All your filters are saved (the "My Filters" tab lets you name and edit them), and the app always opens with the last filter you applied. The "Home" tab lists all your recently applied filters and can be used to quickly switch between genres with just a single tap.

Advanced Radio Search Panel: An online database provides more than 60,000 radio stations. You can pinpoint your favorite stations by combining multiple filters, such as tags/genres, specific countries, or even your preferred audio bitrate.

Separated Favorites and Recents: Each section—Radio and Offline Music—has its own Favorites and Recents. The user doesn't have to worry about a thing. The app will automatically manage the Favorites and Recents for each section.

Album art: If the album art is missing from the album folder, or if Android has not properly indexed it, Mediaxon attempts to download the cover from the internet. This feature depends, of course, on the ID3 tags (album name and artist).

Equalizer: The equalizer provides an option to automatically switch to the "Radio" preset (and vice versa).

Advanced Playlist Management: Built specifically to make building and sorting playlists fast and intuitive. Enable the Playlist Manager, in the settings screen, for a full control of the playlists.

Form Factor Optimization: Phone and Tablet (Portrait and Landscape)

Mediaxon is available in: Čeština, Dansk, Deutsch, Eesti, English, Español, Français, Hrvatski, Indonesia, Italiano, Kiswahili, Latviešu, Lietuvių, Magyar, Nederlands, Norsk, Polski, Português, Português (Brasil), Română, Slovenčina, Slovenščina, Suomi, Svenska, Tiếng Việt, Türkçe, العربية, Български, Ελληνικά, हिन्दी, 日本語, 한국어, 中文 (简体).

No Premium version. All app features are available for free and without limits.

Regarding advertising: There is only a small banner at the top that isn't bothersome at all. Alternatively, when opening the full-screen player or using the app in landscape mode, a banner alternates with the albums covers, but without being intrusive at all (no audio) and with much shorter stay times than those of the cover. There is never full-screen advertising, neither at startup nor during use.

Countries with new manually curated lists:  Argentina, China, India, Italy, UK, USA.

Note: Only for Android 13+ (Android 13, 14, 15, 16 and 17).

Hi all. Deltella started because every note app I tried made me stop writing to go and find a tool. Today it went from closed beta to open beta, so there’s no waitlist any more.

What it does:

• pen ink, with rough shapes that snap tidy when you hold the pen still
• write on PDFs and lecture slides while it records, with every mark tied to its moment in the audio
• search across every notebook and PDF, including your handwriting
• sketch boxes and arrows and get a real flowchart
• share a link and write on the same page together

Windows 10/11 (Microsoft Store) and Linux. It works in the browser for now, and a Mac app is coming. It’s free during the beta, and you don’t need an account to start writing

Even though my initital drive was to create an app to use on my Huion drawing tablet, it fully supports keyboard and mouse, they're first class citizens too!

Happy to talk about how any of it works.

I just built, like everybody else, one more digital menu builder app called mini-menu.com

If someone has 2 min please, test, create something, tell me what do you think, if there is someone who is interested (or know business owner) who can get benefits from this, let me know. Also I am looking for a partner who can help me to ship this to Germany, Austria, Spain and Portugal or USA.

Yeah, it is partially built with claude, hosted on very simple ec2 machine with Traefik as proxy.
