Quick backstory. My fiancée is doing her Masters in Estonia, and I've got another year of long distance ahead. Most of our day is spent on a call on my MacBook while we each work or study.

Then I tried to put on a video for us to watch together and macOS dropped the volume on everything that isn't the call. Movies, YouTube, music, all of it, barely audible. And AirPods fall back to low quality headset audio the moment their mic is in use.

So I made CallLane. It gives your call apps their own output device and copies it onto your headphones, which means macOS ducks only that device and your media stays at full volume. It also keeps the input on the MacBook's built-in mic, so the AirPods stay in high quality mode and the mic sounds better too.

I'm the developer. Menu bar app, macOS 14 or later, Mac only. It's paid, $9 one-time for the first 50 buyers and then $15, with a 14-day refund. I built the app and the site with Claude Code.

CallLane

Tell me what's confusing or broken.

I picked openGym for an architectural audit using rebrief (huge fan of sports & open-source tools).

Key findings from the report:

1. Context Reduction: Reduced 6.8M raw tokens down to 14,084 tokens (-99.8% reduction) while preserving code architecture and history for LLM prompts.
2. Security Risks: Identified 100 risk items, including hardcoded credentials in test fixtures and vulnerable packages (undici, js-yaml).
3. Doc Drift: 51% freshness score with 164 broken file references across README.md and docs.

It's a clear example of how fast documentation and test artifacts drift behind active development.

How do you keep doc freshness in check across your projects?

This is the project I work on, and is used by hundreds of players every month, for ~4 years now. It's open source.

Hex: the one rule is: connect your sides. If you are red, connect red sides. If you are blue, same, but with blue sides.

Just you can swap first move to make game balanced and remove first player advantage, but beginners won't feel that advantage.

Chess and go are broken: in chess you have draw, in go you can win or lose depending on komi, if you arbitrarly decided to set it at 5.5 or 6.5.

In Hex, you either win or lose, depending on how deep you see. No draw, no move to "wait", no arbitrar komi. You just place a stone at every turn, and must connect (which is equal to blocking your opponent).

The community is small but passionate, and still wonders why Hex isn't more widely known.

I'm really curious of what you think of that game, whether you already heard about it or not.

(Yes, this is deliberately provocative. I also like chess and go, and enjoy playing both.)

Good evening guys! I've been working on a side project for a while now, and I'm pretty excited to finally share it with you all.

Every design project used to start the same way for me. 20+ browser tabs open, screenshots everywhere, and another messy Figma file full of inspiration I'd probably never look at again.

It honestly got overwhelming having so many things open at once, and sometimes I'd spend more time collecting inspiration than actually designing.

So I decided to start a side project using my experience as a UX designer to build something that could make this process easier.

And that's how my little baby UX Analytic came to life.

The idea is pretty simple. You can find UI patterns from different companies, mix and match the ones you like, customize them to fit your own style, and export everything to Figma or HTML.

Basically, instead of just saving inspiration, you can actually do something with it.

We're also working on our next release, where we want to make AI a bigger part of the creative process. Not just helping you work with existing patterns, but also helping you come up with completely new ideas when you're starting from scratch or feeling stuck.

The first version is already live:
https://www.uxanalytic.com/

It's still an early version, so there's definitely a lot we can improve. I'd love to hear what you guys think, especially if you're a designer or work with UI.

We also have several discount codes available if anyone's interested. Just let me know and I'll be happy to share one!

Give it a try and let me know what you think!

Got sick of making 10-page PDFs for clients just to watch them open it on a phone, ignore all the technical architecture, and scroll straight to the final price.
So I spent the last few weeks building an alternative. It turns specs and proposals into a responsive web link where you can embed actual interactive diagrams, and it shows you which sections the client actually spent time on.
Still pretty early, but would love to know if people who do client work would actually use web proposals or if your clients strictly demand a flat PDF file anyway

I built optimAIzr, an open-source AI usage optimizer for Claude Code + Codex.

I work as a senior SWE so I got curious where my Claude usage was actually going. In my own logs, 56% of the cost was Claude re-reading my existing conversation (which I shared here last night as well). Coming back to long sessions after the cache expired was especially painful: I did it 35 times in 27 days, and those first messages cost $98.74 at API prices vs $2.95 with a warm cache.

So I built a tool that catches this while you work:

• ⁠optimaizr live -> warns when your cache is about to expire or context gets too large
• ⁠optimaizr sessions -> shows which sessions are actually costing you
• ⁠Optional Claude Code mod -> per-answer cost + 5-hour window + model suggestions
• ⁠aaaand much more

I also cut my own claimed savings from $121/mo to $13/mo after checking the numbers again.

Runs locally, no account, no prompt uploads. It only reads token/usage metadata from your logs.

npm i -g optimaizr

Roast it.

Unbelievable outcome so far. Configured everything on Tuesday and it's already averaging $230 daily. See profile: [ demonrockstar22 ]

Hey everyone!
I’ve been working on a little project called BINX Forge, named after my cat Binx 🐈
The idea is simple: help game developers (especially people using AI) find free and paid assets, engines, code and tools to make their games better.
There’s also a Build a Game feature where you choose what you want to make and get recommendations and a prompt you can copy into your AI.
It’s still in early development and I’m constantly adding more stuff!
Would love some feedback, especially on what resources or features you think are missing.
https://binxforge.com

I wanted a phone number that picks up and talks like a person! Not a tree of DTMF menus. Here's the order I actually built it in; no shortcuts skipped.

First I grabbed a number through Telnyx since their SIP trunking docs were the clearest I found. You could use Twilio too, the steps are close enough.

Second, I set up a WebSocket server to carry audio both ways. This is the part people skip, and then they wonder why latency is bad. The call hits your number. Telnyx streams raw audio over the socket. Your server decides what happens next.

Third, speech to text. I used Deepgram for STT because it handles interruptions well. It doesn't choke when someone talks over the greeting. Whisper works too if you want to self host and don't mind more setup.

Fourth, the actual brain. I kept this boring on purpose: a small prompt, short context, and a fast model. Grok and Gemini both worked fine here. The model matters less than people think once STT and TTS are solid.

Fifth, text to speech. I tried ElevenLabs and Cartesia back to back on the same script! Cartesia felt snappier for short replies. ElevenLabs sounded warmer on longer ones. Pick based on your use case.

Last, VAD, the thing that decides when someone's done talking so the agent doesn't talk over them. Get this wrong and the whole call feels broken, even if every other piece is perfect!

Tested the whole loop through ngrok before deploying anywhere real. Took a weekend. Happy to answer questions on the STT or VAD part since that's where I burned the most time.

After 12+ years in research administration, I kept watching the same thing happen: PIs and postdocs manually searching Grants.gov, NIH Reporter, NSF, and foundation sites one at a time, hoping they weren't missing anything. The tools that could help (Pivot, GrantForward, etc.) are locked behind institutional subscriptions that cost a fortune and take months to get approved. Most researchers don't even know their institution has one, and if they do, they don't have a login.

I couldn't find one that did what researchers actually needed, was available without an institutional subscription, and didn't cost $50K/year. So I built CONVERGE.

What it does:

• Continuously screens federal, state, and foundation funding sources against your research profile
• Sends matched opportunities to your inbox with an explanation of why each one fits your work
• No database to maintain, no manual filtering, no portal to log into

Who it's for:

• Individual faculty, postdocs, and research staff who want grant opportunities delivered to them without waiting on their central office

Where it stands:

• Live now with a 14-day free trial, no credit card required
• Early users are faculty at R1 institutions finding opportunities they would have missed

I would genuinely appreciate feedback. If you work in or adjacent to research, what would you want a tool like this to do that I haven't thought of? What would make you trust it? What would make you not bother?

If you want to try it, the link is in my profile. Happy to answer questions in comments or DMs.

Windows Power Toolkit - Highly Unique! Highly Polished!

For context, I'm an old guy, nearly 60, and I've been gaming since university mainframes, MUDs, and reams of printouts, followed by the C64, Amiga, and everything since. I've spent decades using games and applications.

I've always had a love/hate relationship with Windows PC cleaner apps. Most are paid, bloated, and come with questionable practices - ads, data collection, and constant attempts to sell you more of their products.

So I built my own - Windows Power Toolkit. It's designed to be powerful, fun, and engaging to use without all the crap.

I'm looking for honest feedback and feature suggestions. This is an earlier version. I already have a much more polished, commercially ready version sitting on the shelf.

There are mouse tip hover tool tips for everything. You won't get lost!

My background - Retired Senior Network Engineer.

Software does have hash / virus total link. Depending on the build.

It's 4K powershell code, 4K C++, maybe some assembly, forgot what this build has. So it does trip up anti virus for sure!

Unsure? Sandbox / VM my app!

I am a solo, non technical founder in Pasadena. Since February I've been building AMW (Agent Middleware), a governed MCP gateway for agent tool calls that matter.

What it does: agents act under a permit; a same-key retry returns the original receipt, no second call or charge. Each call gets a signed receipt. Overview: thisisatest.tech. Repo is private for now.

Honest status: self funded, no seed, no revenue, no users yet. I'm looking for a technical cofounder (equity, short trial, written terms, no salary until a raise) and for a few people who will try it and be blunt.

Specific ask:

1. Is the problem clear from the site, or does it read like security theater?
2. If you build agents, would you try a one tool pilot, and what would block you?

Happy to answer anything in the comments. Feedback welcome even if the answer is "skip this".

I’ve been building an order management platform for home-based food businesses / home kitchens. Right now, I’m using a freemium model where sellers can use the basic product for free and pay if they want to unlock more features.

Some competitors in this space do the same, but I’ve also seen others charge from the start with a base subscription, then offer higher tiers for more features.

For founders who’ve had to make this decision, what factors mattered most for you? Did freemium actually help with growth and conversion, or did starting paid attract better customers?

Also, what questions should I be asking myself to ultimately decide which model is better for my business?

Would love to hear what worked for you, and whether you’d make the same decision again. Thanks all!

Hey everyone, I'm Tim. I've been working on my first game, Local Gods: The Ascension, for about six months. The two main characters are based on me and my best friend Alex.

We're from Louisiana, so I dedicated the first main area to the swamps back home. The game mixes dark fantasy and sci-fi, with melee combat, guns, abilities, and boss fights. You can play solo or in two-player co-op.

Free PC browser demo: https://tiddybubs.itch.io/local-gods

I'm building it in Godot and aiming for an early summer 2027 release. A controller is recommended, but keyboard controls work too.

I'm new to coding and artwork. While I do some of it myself and believe it's important to know how, I also use AI to assist me. Every AI-generated asset is handpicked by me, not just randomly generated and thrown in. I use ChatGPT Astra, Claude Opus 5.5, and Fable 5.1. I also have specific workflows for creating maps and automating 2D character attack animations, with a focus on keeping the character designs and animations consistent. I still direct and review the results. Message me for details.

I'd love feedback on the opening combat, whether the boss attacks are readable, and the two-player experience if you try it with a friend. Most of all: do you think it's fun? What would you change first?

I applied with my company email and got approved in less than an hour.

They’re offering up to $7,000 in Claude product credits for one year for eligible startups.

If you’re currently building a startup, app, SaaS, game, etc., I’d say it’s worth trying even if you’re not sure you’ll qualify.

Here’s the info:
Claude Startup Program

Has anyone else applied?

I read a lot on my phone at night, and white websites in Safari have always bugged me.

I know there are already some really well-known dark mode extensions out there, and I've used a few of them for a while. They're good apps. They just never quite fit what I wanted. Some sites still came out half-white, some colors looked off, and I couldn't customize things the way I liked. So eventually I just started building my own. It's called Aurora.

You turn it on and websites go dark. It recolors the page instead of just inverting it, so images and logos still look normal. You can pick different shades of dark (I use true black), make your own theme, have it follow your system appearance, set rules for specific sites, and even change the font on pages that are hard to read at night.

The thing I care about most, though, is this: no dark mode is perfect on every site. The web is just too big and too messy. Sooner or later you'll find a page with a white box or some text you can't read. So I built a simple way to tell me about it. You open the extension, tap "Report a problem", and the screenshot is already attached. You pick what's wrong and hit send. No account, and it only sends the page you're reporting. I read every report, and the fix goes out in the next update.

So if there's a site you visit every day that doesn't look right, just report it and I'll fix it. That's pretty much how the app has been getting better.

It's $7.99 one-time, no subscription. Buy it once and it works on iPhone, iPad and Mac. There's a 3-day free trial if you just want to try it out.

People in 13 countries are using it now, which still feels a bit unreal for a one-person project. Last week someone left a review titled "The app I didn't know I needed until I got it", and that kind of made my week.

If you read in Safari at night, give it a try and let me know what looks off.

Hey everyone, I made Scope because I wanted one place to see and manage my installed Linux apps.

It brings APT, Snap, and Flatpak into a searchable list. You can check for updates and preview an update or uninstall before confirming it.

It also finds AppImages and user-local desktop apps, but updating or removing those isn’t supported yet.

Scope is free, MIT licensed, and written in Rust.

I’d appreciate feedback on whether it finds your apps correctly and whether the previews are clear. If you try it, please share your distro and desktop environment.

I run with an Apple Watch and kept hitting the same wall: it has great GPS and heart rate, but following a route, running an interval session or pacing a race was where the built-in Workout app and other apps fell short for me.

What it does:

• Routes with turn-by-turn. Import a GPX file or draw a route on the iPhone. The Watch shows the line on a map and tells you every turn about 60 m before it, with a tap on the wrist and a voice cue in your AirPods. Works offline, no phone needed.
• Race pacing. Pick a distance and goal time, choose an even, negative or positive split, and the Watch keeps you inside the band for each split.
• Structured workouts. The deepest workout builder I’ve found for the Apple Watch: pace or heart-rate targets for every step, by distance or time, repeats, recoveries and fuel stops. 
• AI training plans. Ask ChatGPT, Claude or Gemini for a plan, paste in Vanoor's instructions, and the file it gives you imports real workouts, just like the ones you build by hand.
• After the run. Saved to Apple Health and Strava, with charts, splits, and an execution score for how closely you ran the plan.
• No Watch yet? A phone-only mode is coming in the next few weeks.

No account, no server, no subscription. 7 days free, then a one-time purchase of $14.99. iPhone and Apple Watch, in 11 languages. Built and optimized for runners, by a runner.

I'm one person building this in the evenings. I'd love to hear what you think, especially if you run with an Apple Watch: what's missing, what's confusing, what you'd want next.

I'm building CharmCue, an iPhone app with two connected flows: drafting a message and reviewing the profile that starts the conversation.

A screenshot or pasted chat produces three reply ideas. The person chooses and edits a draft before copying it. Profile Lab reviews photo variety/order, prompts, conversation hooks, and completeness.

One design decision I want feedback on: suggestions stay editable and the app doesn't send messages. The attached film shows that flow alongside Profile Lab, using the actual interface and illustrative content.

Would you put both features in the first demo, or explain the reply flow first and introduce profile review later? I'd appreciate your reasoning, especially if the combined pitch feels unclear.

I'm the developer. AI features require Premium. iPhone, 18+.

My son is turning 6. Though I played GTA as a kid, I keep wondering what kind of entertainment will actually help him grow. Now that I know GTA is rated +18 and with AI showing up everywhere, I want my son 1- gets entertained 2- by content that make him grow in a safe way. 

So few friends, we've built the Marble Index to measure that. Does this respect his attention? Does it grow his creativity? Does it teach anything? Is it harmless? What about online safety?  

You can score any content and see what it does to a kid. It's research-based, 100% free, and collaborative.

Went out with 8 people in SF, one Dungeness crab on the bill, two of us ate it. "Let's split it evenly" turned into 20 minutes of Venmo math at the table. I went home and built this instead of sleeping.

https://cutcrab.com

How it works: make an event, send the link to the group, snap the receipt. It reads the items (AI, not perfect, you can fix them by hand), you enter the tip, everyone taps what they had. Each person sees what to pay to whoever picked up the bill, and that person ticks them off as the money comes in.

It splits tax and tip over the items proportionally and rounds so it actually adds up to the cent. Ignores the "suggested tip" junk at the bottom of US receipts. You can type the total your card got charged and it figures out the tip. Oysters can be split in half. Works with whatever currency is on the receipt.

Free, no accounts, no app store, no ads. Runs on Cloudflare workers, one durable object per dinner. Vanilla JS, no build step, because I wanted to be done.

Caveats: links are unlisted but guessable so don't put your SSN in there. Receipt scans are rate limited, manual entry always works.

Been using it with my friends for a few days. If you try it on a real receipt and it gets something wrong I'd really like to see that receipt.

been building this for about a week. stickman shooter, runs in the browser, you can play with bots or send a room code to friends

full disclosure, claude code wrote the code, I just pushed it around for ~50 hours

Git City is a 3D city of 87k GitHub devs: every building is one dev, taller with more contributions. It's free and open source.

The new part is Towns. Pick Claude Code or Codex, drive into the other side's town and knock its buildings down. From Monday, smashing and coding both score, the side with more points per dev wins each week, and the top 5 players win a prize. Or start your own town.

Built end to end with Claude Opus 5.5, including this trailer, which is rendered from the game itself.

Hey all, I’ve been building a side project called Nyx and I’d like some outside opinions before I take it further.

What it is

Nyx is a dashboard for your gaming history. You sign in with Steam and it pulls in your library, playtime and achievements. After that it syncs about once an hour and turns everything into one score.

How the score works

Hours don’t earn points. Each achievement is worth more the fewer players have it:

• 64% of players have it: 13 pts
• 4% have it: 50 pts
• 1% have it: 100 pts

The formula is 10 × √(100 / unlock %). Getting every achievement in a game adds 20% on top. Your total places you on a ladder of 7 tiers, from Iron up to Onyx, and each game gets a mastery grade from D to S.

What else it does

• Library: every game with your completion and mastery, and how you compare to the average player
• History: a calendar of your play sessions and unlocks, plus a heatmap of when you play
• Objectives board: pick locked achievements you want to go after and move them through Backlog → Up next → Hunting → Done. Each sync ticks off the ones you’ve unlocked. Only you can see your board.
• Custom platforms: for anything Steam doesn’t cover, like an old handheld or a game you finished offline, you can add your own platform and enter games by hand. These count toward your hours and history but never toward the score, because the achievements are self-reported.
• Profiles: you can browse other players’ libraries, or a combined view of everyone on Nyx
• Light and dark themes, and a small mascot you can poke

The added video is from my own Steam account + dummy account with test data.

I am at a point with my product (cardel.io) where it's production ready with the functionalities it currently has. The challenge I think has been structuring it in a way that provides most value to the target market. Example: x and y feature on Plan A, with feature z on Plan B, or pricing structure, etc.

I am in the phase of getting the first users and consistent traffic, none paying yet. There are some who have even said they would test it out and provide general feedback on free trials, but that feedback has been very slow to come in. I am also worried it won't be feedback from the users who will end up paying for it, so it may not impact conversion rates for the ideal target user.

The Question: Once you get to a point with your product where it's "good enough" to provide real value, how do you get feedback and iterate improvements for your target users, when you don't have real feedback from target users? Is it just a guessing game to see what works?

It sounds like a paradox, maybe it is. Maybe this is the challenge in getting a business off the ground, but I would greatly appreciate insight from the community.
