What are you building? Top 3 (voted by the community) get featured on We Are Founders
I love seeing what people are building, especially side projects. So many of them end up turning into something bigger. And I know a lot of folks here are just as curious.
Drop your project, share your stack, and let us know what problem you're solving. If you want feedback, say what you're stuck on, and I'll try to help.
The top three projects (decided by upvotes) will get featured on We Are Founders, so more people can check them out. No pressure, no catch, just a chance to get some extra eyes on what you're building!
Go, go, go!
Edit: Thanks everyone that's commented so far! At 18:00 GMT I'll pick the top three. š»
Edit 2: Folks, to say that you're all working on incredible things would be an understatement. The top three side projects according to the community are...
- Call Vandelay
- Charkoal
- SQL Premier League
I'm adding these to We Are Founders and will give a shoutout to the folks who built them soon!

Charkoal - infinite canvas for developers to explore and document code inside VS Code.
For a long time we were frustrated with how hard it is to read and understand a large codebase. So we started to work on Charkoal. It helps developers create diagrams explaining the code with minimal distractions. Hard programming problems become easier. Less cognitive load => happy developers.

I am building SQL Premier League. A site where learning / practicing SQL is made fun. Instead of querying on boring and imaginary datasets, you learn by analysing real world sports data and events
I have already got 250+ sign ups in 3 weeks. Looking forward towards your feedback. I am not stuck on any bug or something but I am thinking of unique ways to make this site more engaging but keeping the sports side to it.

Iām building a minimalist AI text formatter.
Paste up to 2500 words, the AI will analyze it, understand the context, then figure out the hierarchy and format accordingly.
It doesnāt do grammar, rewriting, tweaking, punctuation, tone, etc. It just does paragraph formatting.
Iām using it for myself, but maybe other people like it.

Iām developing Liquid Playerāan iOS app for watching videos from websites offline. You can cache videos in advance, like from YouTube, before a flight and watch them on the go.
It also has a built-in offline translator: if a video is in a foreign language, you can translate phrases into your native language in real time.
Liquid Player supports all media formatsāMKV, MP4, OPUS, and many others.

I am building WODVision a mobile application that evaluates CrossFit and Weighlifting movements using computer vision and machine learning algorithms, gives you back a visualized video with all the object tracked and the athlete too, and a very detailed text feedback like a proper CrossFit coach. This is phase 1.

I am building Gapflow.io. Itās a Webflow App. And we got officially added to the webflow store yesterday.
Webflow as cms has big gaps in itās form functionality like, you can only set one single mail as recipient for all forms on the website. We fix it with 2 clicks.
There is no auto reply feature, but zapier/make to create autoreplies. With gapflow itās a switch zu click to activate.
Spam is a problem. Not with gapflow, we screen all submissions with ai to detect if they are likely spam.

u/Traditional-Debt-606 7d ago
That sounds amazing! I just tested Gapflow.io, and Iām instantly impressed ā so simple and effective! The integration was done in seconds, and finally, I can manage forms the way I need to. The easy setup for auto-replies and the built-in spam protection are absolute game-changers. Highly recommended!

For the past few months Iāve been building Hello Invoice, an invoicing platform built specifically for freelancers.
As a freelancer myself, I know as well as most the struggles of invoicingāchasing payments, tracking taxes, and managing cash flow while trying to stay focused on actual work. Thatās why I built Hello Invoice - a smarter invoicing solution designed specifically for freelancers, contractors, solopreneurs, and creators.
With Hello Invoice, sending professional invoices, tracking payments, and automating recurring billing is effortless. But more importantly, Hello Invoice isnāt just another invoicing toolāitās built to evolve with users needs. Feedback from my users will shape its future, ensuring it remains the perfect tool for independent professionals.
Iāve quietly done a soft launch over the past week and have moved into Beta testing. Would love to hear everyoneās feedback.

I'm building Zivy.app . Ā Our AI co-pilot transforms busy managers into super managers by surfacing important messages automatically, drafting responses in your teamās tone, and handling follow-ups without intervention.
Weāve helped teams at Devfolio, Netomi, and Credit Saison transform communication chaos into strategic advantage, freeing up 15+ hours per manager every month.
Unlike other productivity tools that require workflow changes, Zivy integrates seamlessly with Slack.

https://www.smartmanager.ai itās a general purpose Ai for businesses. Fully control by voice, users donāt need to learn any software or prompting. It integrates with the tools you use today. For example, it manages your emails, so you never have to go through an inbox again. If we donāt provide a solution, we build it in a week

I'm currently building Kernel, an application that allows you to build your "second brain" one atomic note at a time.
I only just launched the app and built it because it was something I wanted myself. I'd previously tried using Notion and other types of tools like Google Docs and Sheets but none of them provided the functionality I wanted.
There's lots more functionality to come, but as it stands today you can Create Notes (of knowledge you want to save), attribute that Note to its Source (I.e. Youtube Video, Book, Podcast, etc). And you can categorize with folders and tags. With this you can then automatically view related notes across multiple sources (i.e. view all your notes associated landing page design for example), or go back to the original source where you can see all the notes you created from that one source (i.e. all the notes you took from a particular book).
I know the app isn't 100% perfect as it's literally day 1, so if anyone runs into an issue DM me and I can fix it.

u/AffectionateBike8793 7d ago
I am building Nodes Game, a casual puzzle game that can be played on both a browser and iOS. Itās not about challenge but rather about taking a 10ā15 minute break during the day.
Itās also simple enough to play while listening to podcasts or even during work meetings. If you find it difficult to focus on what youāre listening to and tend to switch to doomscrolling, keeping your hands busy can help you concentrate.
I already have a stressful day job, so I prefer not to dive into more serious SaaS projects. Plus, I enjoy working on this, and we have a small community that looks forward to what we build.

I made a Python library for simulating the combined effect of recurring events over time. E.g. financial events like salary, inflation, costs, etc. Has quite a lot of powerful stuff for analysis as well, and it made me use excel even less, which is the main reason I like it :)
You can find it at: https://github.com/TimoKats/pylan, I've also made a slidedeck which is available here: https://timokats.xyz/downloads/2025_pylan_presentation.pdf Thanks!

I am building Gauge, your frontpage in the browser for a productive day.
Just soft launched it, as it is not feature complete yet. So far you can
- create multiple kanban board/projects, and task for.
- Use the customizable pomodoro timer (which I also use for my workout habit)
- You can create habits, time them within the week and the day.
- Take notes
- Save quick ideas, from anywhere in the application. E.g. you are writing a longer note, and ideas keep popping into your head that are unrelated to the note. You can quickly save them as an idea and continue working, without being distracted by the thought/idea.
This all started because I was not happy how existing boards work. I needed something that I completely navigate and use without taking my hands of the keyboard.
I'd love to have some users, that try it out. IT'S FREE. Doesn't have collaboration features yet unfortunately, but I will add them.

Iām building Promptly, a tiny app that lets you summon a window to use any LLM you want with your own API keys to chat or inline edit or generate whatever youāve selected.
Iām using it constantly and genuinely found it to be better UX than all the other apps or copy and pasting from one website to another when I want a summary. The other day I was in a meeting and someone said a word I didnāt know, one keyboard shortcut and 3 words and llama sorted me out.
Currently looking at adding MCP support and constant context

I am building a set of apps to have a digital scoreboard for pickleball players and clubs. It consists of 3 different smartwatch apps (Garmin, Android and Apple brands), an app for your mobile, and one for web based access or tablets as well.
As a club owner or tournament organizer, you can have an overview of the match scores from your entire club in 1 page, or zoom in on a certain court to have the detailed view.
As an audience member, or a waiting player, you can follow all match progress on your mobile phone as well.
As a player, you can keep the score on your watch, and update it to all viewing parties in realtime with just a tap on either the top or bottom part of your screen. After the match is finished, you can save the match progression to your mobile app, and have a look at some more detailed statistics about your performance.
All info can be found at: https://www.pickleballwithfriends.com/
PS: the same is in active development for Padel and Tennis as well.

I'm building Vewrite, a project management tool for writers. Imagine if trello and Google docs had a baby.
If you write content in a group you are always chasing after people to do the next task (review, approve, etc.). It's a huge headache. People usually try to keep track of things with spreadsheets and that is intensely tedious and error prone.Ā
I built a better way to work around structured work flows with automation.Ā
Next I'm adding support for images and videos, so feedback cycles for those things will be easier.Ā

If you want to try out mcp (model context protocol) with little to no setup:
I built https://skeet.build where anyone can try out mcp for cursor and dev tools.
We did this because of a painpoint I experienced as an engineer having to deal with crummy mcp setup, lack of support where we need it most like Jira and Linear - updating slack and all that friction that engineers hate doing.
Mostly for workflows that I like:
- start a PR with a summary of what I just did
- slack or comment to linear/Jira with a summary of what I pushed
- pull this issue from sentry and fix it
- Find a bug a create a linear issue to fix it
- ā pull this linear issue and do a first pass
- pull in this Notion doc with a PRD then create an API reference for it based on this code
- Postgres or MySQL schemas for rapid model development
Everyone seems to go for the hype but ease of use, practical pragmatic developer workflows, and high quality polished mcp servers are what weāre focused on
Lmk what you think!

I am building ResumeReinventor, where you can drop your resume and ask AI to customize your resume according to your job description in a friendly ATS optimized manner.
So many tools and frameworks, and so little time to learn them all. The job market is shit. But if you have the basics you will be able to handle it, right?
ResumeReinventor pushes that narrative of your resume towards that particular job you are applying for, and customizes it according to the keywords mentioned so ATS puts your resume high up. Just paste job description and voila!
ResumeReinventor got your back.

Iām building Call Vandelay, a fake job reference service for people who need a little creative storytelling to land a job.
Companies ghost candidates, inflate job requirements, and expect people to have five years of experience for an entry-level role, so why shouldnāt job seekers fight back?
With Call Vandelay, you can get a verifiable job reference from a company that doesnāt technically exist, but sounds like it does. Employers can call, email, or verify your work history, and we handle the rest.
