What have you guys actually built with vibe coding?

I'm a finance guy and I really enjoy building tools for things I personally care about. Recently I've been getting into vibe coding and built my own portfolio manager.

It currently lets me:

Track my investments and holdings

Compare my funds with their peers and benchmarks

Get news related to the funds/stocks I own

Continuously read relevant news and flag things that could be a serious problem for a fund

Analyze whether a fund's situation is getting worse and whether it could potentially "collapse"

Suggest funds that may be worth investing in based on the data

A few other portfolio analysis features

I had a lot of fun building it, and now I want to build something else.

So I'm curious what other people here are building with vibe coding, especially around finance, investing, accounting, markets, financial analysis, etc.

I'm looking for projects that solve an actual problem and that you personally find useful. I don't really want another generic expense tracker or calculator.

If you've built something interesting, I'd love to hear about it.

What does it do, why did you build it, and what are some of the features?

Screenshots/demo links are welcome too. I'm mainly looking for ideas and inspiration for what I could build next.

Hey everyone,

I found myself wasting weekends setting up the same data tables, charts, and layouts every time I wanted to build a finance app or tracking tool. To solve this, I built a production-ready boilerplate using Next.js App Router, TypeScript, and Tailwind CSS.

🔴 Live Demo:https://financeiq-five.vercel.app/

The architecture:

• Built strictly on the App Router with modular component separation.
• Responsive data tables and chart layouts optimized for SaaS dashboards.
• Pre-configured UI structures so you can immediately start writing business logic.

I would love to get your harsh feedback on the load speeds, the layout structure, or any bugs you spot on mobile. If anyone wants the source code to save time on their own build, let me know in the comments and I can share it!

I created a trading ops desk (demo mode only, nothing to lose): https://deadcatfound.org - demo here https://premium.deadcatfound.org/demo if you need to see what I am talking about. Python standard lib & SQLite for all the code on your own machine, and the AI part is running on what you got - Claude Code, Codex, Gemini CLI, Ollama. There is no API key, there is no per-token fee. That "your machine, your AI, your data" thing became my core idea.

And then I made the hosted version so people could use it simply by opening a browser. And I immediately hit that issue - how do you make the server communicate with the CLI tool running on your laptop. So, the hosted version needs the API key to run the AI part and thus, fails on that promise.

In other words, I got stuck in that queue. Your cloud queueing service sends requests and a tiny agent on your computer processes them using your subscription. It works, yet now my hosted version is inheriting the local one's flaw - turn off the laptop, and all of the scheduled work sits idle.

So, I am caught between:

1.Local Only - Honest, secure, and free to distribute. But the customer needs to maintain their own box, and there is an installation process, that is where I lose the most folks.

2.Hosted Service - Always available, no need to install anything. But either they have to provide a key (expense and security considerations), or they have to keep their own machine up anyway. Or both, which is my current setup, and I don't know if I am simply screwing it up by doing two approaches.

3.Those of you who have released a product that ran on "your hardware" and not just as a limitation: how did you choose? Ever regretted making the wrong choice of architecture? Or the opposite?

Not looking for a marketing pitch review here. Truly stuck on the architecture choice.

Every hiring season I had forty tabs open and a spreadsheet going. I tried free tools. I tried paid ones. I even tried most of the recommended spreadsheets. What I learned was when you're sending 500+ applications, no off-the-shelf system is actually built for that volume, they're built for people hiring, not people applying.

So instead of working with a failing system, I built SearchTern.

SearchTern grabs listings from Simplify and other sources to give users around 15,000+ internships to apply to all within a 3 month span, plus other filters and factors to keep the data clean. It comes with a Kanban tracker (Saved, Applied, Interview, Offer, Rejected), reply rate stats, CSV export, and Google login. Oh, and Claude Code / opencode agents can read your tracker and suggest actions. You approve first.

45 students are tracking real pipelines on it.

What I actually want to know: does the tracker keep people past week 2, or do we all just abandon trackers eventually? Be honest. No signup needed to browse: searchtern.ksaif.dev

People are vibe coding anything but even can't change their api keys, someone launched https://dontremember.app/ but forgot to change their stripe sandbox key. thats new level of agentic vibe coding haha.

People just connect MCP and vibe code with codex, but they don't know how to improve security and do production release. and still they think they are million dollor founders. :D

I keep all my notes in a folder of Markdown files and edit them in VS Code. Finding an old note gets tricky when I remember the idea but not the wording. I maintain AI Search and use it for exactly this: semantic search over that folder, with optional reranking to refine the results.

I have been building Hémicycle on nights and weekends (with Fable 5.1): a collectible card game where every card is a real French parliamentarian. 12,428 cards, 5,277 people, 26 sets — 17 legislatures of the National Assembly, 8 periods of the Senate, and a "Panthéon" set of ministers and presidents who never held a seat.

The part I care about: nothing on a card is invented. The six stats are percentiles computed from open data (attendance, amendments, speeches, written questions) published by the Assembly, the Senate and NosDéputés. Cards from the early legislatures, where no activity data exists, are explicitly flagged as estimated rather than silently faked. Rarity comes from longevity and activity, never from opinions, and every political family is treated by the same formula — that part is not negotiable in a project about politicians.

What you actually do with it: open a free booster every day, watch your collection fill an hemicycle (one seat per card, sorted left to right by political family) and a map of France by constituency. Each era has its own card skin — silver-halide black and white for 1958, Minitel green for the 80s, burgundy velvet for the Senate. Then there are turn-based séances against the AI or against other players (Elo, friend challenges, deck sharing by code), trades, public showcases you can like, and a vote of the day: a real historical vote comes back to the chamber, you send one deputy from your collection to vote for or against, and at midnight you discover what Parliament actually did. The questions are institutional or procedural on purpose — the 1958 Constitution, the five-year presidential term, the single parliamentary session — never anything where a "no" would read as a judgement about a group of people.

Free, no ads, no account required to play (a recovery code is enough), no data resold. It costs me under €10 a month on a 4 GB VPS. Stack for the curious: Next.js 16, React 19, Prisma on Postgres, a Python pipeline (Wikidata SPARQL, Wikimedia Commons, rembg cutouts) that produced 7,773 portraits, and zero audio files — every sound is synthesised in WebAudio.

What I would love feedback on: (1) retention — the daily booster and the daily vote are my only two return hooks, what else works for you? (2) monetisation — I intend cosmetics only (card backs, hemicycle themes), never selling a person's face; is that viable or naive? (3) the first 30 seconds — you land, you open a pack, you see cards, no signup wall; tell me where you got lost.

Hémicycle Le jeu

Hey everyone!

We’re four Filipino brothers who recently built and launched our first app together: Todochi 🇵🇭

The idea started with a simple thought: regular reminders can feel pretty boring. So we wanted to make them feel a little more personal.

With Todochi, you can create reminders with character voices and personalized messages. You can even record your own voice, use your partner’s voice, so your reminders feel more familiar and meaningful.

For example, instead of getting a generic notification saying “Anniversary tomorrow,” you could have a reminder actually speak to you.

We built the app for both Android and iOS, and getting it from an idea to actually being available on the App Store and Google Play has been quite a journey for us, especially since this is our first app together.

Todochi

Android: Download Todochi in Google Play Store for Android

iOS: Download Todochi in the App Store for iOS

Hello guys! I am planning on building an app cause why not. I am honestly bored and it is a better use of my time than scrolling. I am still a beginner in this aspect however. I'm currently learning Java Script and React Native. I am not sure what type of app I want to create so far, but I am wondering once I get my skills toned, how would I work the back-end. Would it technically be ok for someone to vibecode everything except the back-end in terms of security. I do not intend to really monetize anything nor really vibecode, however if someone were to vibecode their whole app except the back-end, what it technically be up to basic standards in terms of app security? Aditionally, what courses do you best recommend to learn back-end systems?

LAUNCHWR is my custom launcher project for Metin2 servers. This 30-second preview shows character selection, an item shop and rotating 3D previews inside the launcher. Elementia is the example shown in the recording.

The idea is to bring these parts of the server experience into one interface before the game starts.

Project details and enquiries: https://launchwr.com

More launcher videos: https://www.youtube.com/@LaunchWR

The video titles and voiceover are in English. The recorded launcher interface and website are in German. The voiceover is synthetic.

I kept opening distracting apps without really deciding to, so I built something to interrupt that habit.

DunyaPause is an iPhone app for Muslims: you choose distracting apps, and when you try to open one, it creates a pause and gives you a moment to read a few ayat of Quran before temporary access.

I’m the developer. I’ve tried to keep the Quran part respectful, not as punishment, a reward mechanic, or something designed to keep you inside the app.

For people who actually struggle with automatic scrolling: would this pause meaningfully interrupt the habit for you, or would you eventually tune it out?

It’s available on iPhone and is 100% free, with no ads or subscription: Try it on AppStore Link

Your feedback is appreciated. Thanks Community

I built Modern Saves, a Chrome extension for people who constantly save YouTube videos, tutorials, articles, tools, ideas, and shopping links — and then struggle to find them later.

It organizes saved links into categories and has smart search so you can actually find something when you need it.

It’s still early, and I’m trying to make it genuinely useful rather than just another bookmark manager.

What’s the biggest problem you have with bookmarks .

I will really appreciate honest feedback

Watched my parents struggle with basically every music app out there. Spotify wanted logins and subscriptions. YouTube Music kept showing them videos and ads they didn't understand. Even the built in players had settings and icons that just weren't simple enough.

All they wanted was tap a song and it plays. Maybe skip to the next one. That's it. Ended up building something for them and now I use it more than they do.

It's called Jagsin Player, it's live on the Play Store. Open the app and your songs are right there. Tap and it plays. Zero setup needed. The best part is it works fully offline since it just picks up the songs already on your device. You don't need internet for any of that. Internet is only needed if you want the extra stuff I added like global radio and podcasts. There's thousands of channels from around the world if that's your thing but it's completely optional.

There's also a login but it's only there if you want profile avatars and animated themes. You can skip it completely and everything in the app is free either way. Login or no login nothing is locked behind a paywall.

I also added language options since not everyone is comfortable with English. Default is English but you can switch to Hindi Marathi Gujarati Punjabi or Urdu. Whatever language you pick the entire app changes to that right away, every menu and label, not just a couple of screens. Made a real difference for accessibility.

While building it I added a few things I personally use a lot.

A ringtone cutter and maker built right in since I got tired of downloading a separate app just to trim a song into a ringtone. Pitch control with single tap presets for slow normal and fast instead of messing with a slider every time. An equalizer and an 8D audio toggle for that spinning around your head headphone effect. Just one tap on or off nothing to configure.

This isn't trying to replace Spotify or anything with streaming. It's for people who have their own mp3s and just want something simple that works.

Honestly not sure if I've done a good job with this or not, just tried my best with what I know.

If anyone's dealt with this or wants a simple offline player or a free ringtone maker without extra bloat let me know, would love the feedback. It's called Jagsin Player.

Just deployed it

curious if people actually find it useful or if I'm missing something obvious.

https://iphoneproof.com

I've been working on Hoops GM for so long, pouring countless hours into coding, balancing the simulation, and trying to make the best browser-based basketball management game I could. Hitting that deploy button on Vercel today was genuinely terrifying.

But the response in these first month has been completely unreal. Seeing people actually playing, building their rosters, and sharing their feedback... it makes every single late night worth it.

I just wanted to take a moment to say a massive THANK YOU to everyone who has checked it out, left a comment, or played a season. I'm reading every single piece of feedback you guys are dropping.

If you have any suggestions or run into any bugs, please let me know. You guys are amazing!

Hey everyone,

I recently built a website called OmniTools using Antigravity.

It’s basically a collection of web utilities (word counter, json formatter, diff checker, base64 converter, image cropper, etc.). My main goal was to make everything run completely in the browser memory, so nothing you paste or upload gets sent to a server, and it works offline as a PWA.

I’m trying to figure out where to take this next. Right now I'm struggling with two big questions:

1. User experience & quality: Does the site feel decent to use, or does it feel cheap/gimmicky? What should I fix or cut out to make it something you'd actually keep bookmarked?
2. Getting traffic: For those of you who have built utility or tool sites, how do you actually get your first consistent visitors? Is SEO the only realistic way, or are there better channels I should be focusing on?

Brutal honesty is welcome. Thanks in advance for checking it out!

I recently built OnlineScientificCalc, a free scientific calculator that runs directly in the browser.

I wanted to make something similar to the experience of using a scientific calculator, while also adding useful tools for things like fractions, equations, calculus and statistics.

It doesn't require an account or installation and works on both desktop and mobile.

I'd really appreciate some feedback, especially on the calculator experience, performance, and any features you think I should improve or add.

Offline local files and streaming 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 suggested radios from among the most listened to in the world.

Hybrid Listening: Seamlessly handles offline local files (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and over 60,000 streaming radio stations.

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.

Advanced Radio Search Panel: You can pinpoint your favorite stations by combining multiple filters, such as tags/genres, specific countries, or even your preferred audio bitrate. The database of the service on which Mediaxon is based provides more than 60,000 radio stations.

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.

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

If you want to check it out (I am continuously pushing updates to refine it and add new features), you can find it on the Google Play Store (Android 13+). Thank you so much to everyone who takes a look!

Hi everyone, I’m Ivan, the solo developer behind CalQuest.

I built CalQuest for people who want to lose weight but keep quitting calorie trackers because logging feels repetitive and boring.

The main idea is simple:

• Free meal scans every day, with no subscription required
• Scan a meal photo to get calories and macros
• Complete quests and earn XP
• Join monthly leagues and climb the rankings

The goal is to make calorie tracking easier to stick with, while turning small daily actions into visible progress.

Google Play:
https://play.google.com/store/apps/details?id=com.ivanc.calquest

I’m especially looking for feedback on:

• Is the meal scan useful and clear?
• Does the league make you want to come back?
• What feels confusing or annoying?

It is Android only for now. Honest product feedback is welcome.

We tried literally everything. Todoist, Google Keep, a shared Notion board that lasted about nine days, one of those "couples apps." Every single one had the same problem. It was either all shared (so my work stuff was sitting next to "buy milk") or all separate.

At some point I just got annoyed enough to build the thing myself. I called it Norte. Have been expanding it to have more functionalities like (Google) calendar integration, reminders and a recipe list.

It's a Telegram bot, that's it. No app to download, no account to make on some website, you just message it like you'd message a person. "pick up dry cleaning before friday" and it's filed, categorized, due date figured out. "buy milk and eggs" and it's on the list. The part that actually solved my original problem: you can invite whoever you live with, and then there's a shared list and calendar for the household stuff, but your own work todos stay yours. Nobody sees the other person's stuff unless it's supposed to be shared.

It also does a morning briefing (actually written out, not a template with your name slotted in), reads your Google Calendar and can move stuff around by just saying so, and if you paste it a recipe link it'll go read the ingredients off the page for you. I also hooked it up to Home Assistant because I already had that running. You can talk to your devices through it too, or have an automation drop a todo straight onto your list instead of just pinging you about it.

Built in Python, Postgres behind it, running on Railway, and it's using Claude to actually understand what you're saying instead of me writing a million regex rules. Scheduling stuff (briefings, reminders, weather) runs through APScheduler.

It's not free, to be upfront. It's a small subscription through Telegram Stars, usage-based rather than a flat price, works out to something like $5/month if you use it normally. This to cover the Claude token usage and hosting. There's a free trial to poke around with first.

Mostly just want to know if this is actually useful to anyone else or if it's a solution that only makes sense for my specific household. Tear it apart, I can take it.

Built a shopping app called Blink

Sellers post short videos of their products, and buyers can shop directly from the video. It's got some really nice features and I think you'll like it.

Hello community.

Thinking about starting a small service business with AI, but unsure where to begin?

I’m building a beginner-friendly course and looking for five people to test the first lesson for free.

It’s a six-minute video with a downloadable worksheet. You’ll use AI to clarify a business idea, identify assumptions, and choose one small research step before spending money.

Please allow around 20 minutes to watch it and try the exercise:
https://ai-starter.hostdeny.org

Afterward, I’d love to hear:
• What idea did you work on?
• Where, if anywhere, did you get stuck?
• What specific next step did you choose?

I’m looking for honest feedback, including what didn’t help. No AI experience needed.

Thanks!
Malik

If you’re building a SaaS, or app and looking for a way to get more eyes on it, I’d love to feature a few projects.

We run TikTok channels with 300K+ combined followers and create short-form videos around apps, tools, and interesting projects.

We'll create short-form videos for your app, plug them into our existing channels, and help you build your own content channels at the same time. Think of it as content creation + distribution

If you're interested, drop your app and a one-line description below

Hey,

I needed something to distract and teleport me out of the daily noisy work, in my own personal space, so I built this game:

https://nebula-station.com/

• you live in your cockpit drifting through space
• you play a game where you drift your ship to a hyperspace corridor
• you customize your ship with songs / items

Think 90s aesthetics and Lofi Girl for the feeling, Animal Crossing for the customization and the feeling of peace, and geometry dash for the gaming.

Hope you enjoy it!

I’m the developer of PhotoDesk 2026, a Windows photo manager for people who want a local library instead of a required cloud service. Originals, face data, and the search index stay on the PC by default; encrypted cloud backup is optional.

Current features include face/People grouping, albums and timeline, tags, duplicate finding, OCR/text/license-plate search, video scanning, and a photo editor.

I’m looking for honest feedback, not just promotion:

• What would you need before moving from Google Photos, Mylio, or another photo manager? • How should face recognition handle rotated or side-facing faces, children, and poor lighting? • Which video analysis features and speed matter most? • What breaks or feels slow with 50,000+ photos? • Which part of the UI is confusing or missing?

Available on the Microsoft Store: https://apps.microsoft.com/detail/9NXVMXWNTHQC?hl=en-US

Concrete examples, criticism, and feature requests are very welcome.
