Hey r/SideProject 👋 I've been building SubSignal ( subsignal.ai ) for the last 7 and I'm finally ready to put it in front of real people. The problem I kept running into: People constantly ask for product recommendations on Reddit - "what tool do you use for X?", "anyone know an alternative to Y?" - but by the time you stumble across the thread, it's buried and 40 comments deep. You miss the people who were literally asking for what you sell. Another big issue f...

yo so been grinding on this voice tool lately and realized most productivity apps just pile features on top of features. nobody actually uses half the stuff. what's your approach when building something? like do you start with one core thing and expand, or do you try to nail the experience first before adding complexity?

Built a Chrome extension as my first product ever. No audience. No connections. No clue what I was doing. Here's what actually happened: The product Reddit's saved posts feature is basically useless if you save more than 50 things. One flat list. No search. No labels. You save something at 2am thinking you'll read it. You never find it again. So I built Readdit Later. AI-powered manager for your Reddit saves. Search, label, organize, export, summarize - all from a Chrome extension. ...

Hey everyone, This is my first post ever on Reddit, and I’m so excited to finally share a project that I’ve spent the last 2 years of my life building and refining to make it the best it can be. It’s a social platform called "Flabtap" designed to allow everyone to freely share their photos, videos, and ideas. You can build new connections, share content with your friends and family, and message each other with absolute privacy. But most importantly, the core mission of my platfor...

As a freelancer, one thing that always annoyed me was how much time got wasted on tiny client requests. "This button should be green." "There's a typo here." "Can we move this section higher up?" "The spacing looks weird on mobile." The actual change takes 2 minutes. But then you have to stop what you're doing, pull up the project, find the right files, make the change, test it, commit it, push it, deploy it, send the client an update, etc...

hi all, I recently asked you to provide your SaaS URL and wanted to show you what opentweet can create. I want to do a 2nd round as the first one went really well. drop your saas URL and I'll generate tweets for your business.

Hi, I’m a solo indie developer working on The Borderless , a cozy floating island management sim set in the middle of the ocean. This is the first trailer for the game, and I’d really appreciate some feedback . I tried to show both the cozy ocean vibe and the actual gameplay loop. Does it make the game look clear and interesting? The demo is available on Steam if you’d like to check it out: https://store.steampowered.com/app/3687370/The_Borderless/ submitted by ...

so I own a directory website where I list apps and websites that I went over, however, they must have a free tier to test, and solve a real problem in order for me to test and write about them. If you own one, please include your socials in the submission. I also write articles about cool softwares and tag their founders. directory website: strictseal.com Lets connect and grow together. I also hope to note see bots in the comment section. Thank you and looking forward to seeing your...

I'm a designer who builds products. Been trying to grow on X but every tool I look at assumes I want to monetise a big audience. I don't. I want to find 50 people who share the same interests. Other makers, founders, people who care about craft. As an introvert the whole "post 5x a day" grind feels like becoming someone I'm not. Curious if others here feel the same — and what you've actually found useful for building real connections rather than just growing a number. &#32...

Got frustrated with how scattered and slow interview prep is so I built grind-interview-questions.com The idea - focus on the most frequently asked technical interview questions with spaced repetition so you actually retain them. AI grades your answers and gives feedback. You also get a dashboard showing which topics you struggle with most, so you know exactly where an interviewer would drill you if they spotted a gap. The alternative is prepping with Claude Code or ChatGPT - but that eats...

Everyone keeps saying we have to use AI, that it’s revolutionary and I totally agree, it saves a ton of time. But there’s a problem with that: it saves so much time that we don’t even pay attention to the data we’re sending to AI, names, passwords, phone numbers, Social Security numbers, we send it all under the pretext of saving time. The problem is that we’re giving it away; we’re sending it to companies whose last concern is our privacy. Imagine you start talking about your eight-year...

I received my application rejection today. This was my first time applying to Y Combinator. I'm wondering if anyone else's build is still checked after being rejected? I'm a solo developer; I've created a vision-to-scent AI pipeline, and I've also built a smart device based on this pipeline.This smart hardware is an aromatherapy fragrance peripheral designed for gamers. It recognizes elements in the game scene and then controls the synthesis of the fragrance via a PWM fans. The hardware also f...

Website : https://voicedelta.com/ I got tired of paying premium prices for basic text-to-speech tools, so I built my own. It's called Voice Delta. It lets you: ✅ Clone a voice from just a few seconds of audio ✅ Generate speech in 50+ languages ✅ Control emotion, pacing, and pitch ✅ Create studio-quality voiceovers in seconds ✅ Use popular ElevenLabs-style voices for English content One thing I've noticed is that many voice AI platforms charge a lot even for basic usage, especiall...

I build plainkit.app, a small set of privacy-minded browser tools. The idea is boring on purpose: open a tab, use the thing, close it. No ads, no signup, no tracking. The whole site loads only from its own domain — no Google Fonts, no CDNs, no analytics beacon. You can check it yourself in DevTools → Network. The newest one is Tetris. Your high score is saved only in your own browser (localStorage), nowhere else — close the tab and it's the only place it lives. For the people who care about ...

I've been building a side project called Moment for the last couple of months. The idea started with a question: Can you remember what you were thinking on a random Tuesday last year? Most of us can remember the big moments in life. Graduation. A new job. A breakup. A big trip. But we rarely remember what we were worried about, excited about, looking forward to, or thinking about on ordinary days. So I built Moment. Once a day, everyone gets the same question at the same time. ...

I'm working on a side project that has been sitting dead in my GitHub repo for a couple of years. I've finally decided to finish it and launch it. The backend is mostly done, and right now I'm working on the landing page. The thing is, I keep finding tiny UI issues and spending time fixing them. Things like spacing being slightly off, button alignment, minor inconsistencies, etc. At what point do you stop polishing and just ship? Do you fix every little thing before launch, or is it normal t...

I kept losing prompts across gpt sites, old chats, and random docs, so I built LMpad - a simple place to discover prompts, save them to your own pad, fill in variables, and run them with any OpenRouter LLM model (free models included). Basically like Google Keep + Pinterest but for prompts and running LLMs. What it does today: Browse community prompts by category Save/remix on a personal "pad" (corkboard-style) Run prompts with variables + streaming output Auto Generate a...

Point your phone at any animal, it cuts the creature out, figures out what it is, and adds it to your index as a little sticker. Common ones, rare ones, the whole thing fills up as you go. It's basically a real-life Pokédex. First test subject was a gecko that wandered into our living room; caught him, added him, released him outside, no geckos were harmed :)

Baby gear screenshots. Pediatrician notes. Sleep schedule posts. Daycare links. Gift ideas. Recipes we might actually cook. Things to do with kids. Random Instagram restaurants for the one night we might get out. TikToks, Reddit posts, YouTube links, Chrome bookmarks, screenshots from texts. I was saving everything and literally dont need another save for later app... I need a FIND it later app That’s why we built Stasht. It’s a place to save posts, screenshots, photos, links, places, event...

I've been following the rapid growth of AI tools and one thing keeps standing out: many developers don't struggle with building great products—they struggle with getting people to discover and use them. Every week I see new AI apps with impressive features, but many of them disappear because they never reach enough users. A solo developer today can build something remarkable in a few days using modern AI tools. The real challenge seems to be distribution, feedback, and early adoption. Rece...

Finally live on the App Store. 🎉 Kash is an expense tracker built for people who gave up on expense trackers. Most apps make tracking feel like homework. Kash focuses on making it fast, simple, and easy to stick with. If you've ever stopped tracking expenses because it took too much effort, I'd love for you to try it and share your feedback. App Store: https://apps.apple.com/us/app/kash-expense-tracker/id6774987648 [link] ...

Been experimenting with SceneKit on iOS and visualizing GPS data points. Really happy with how the results turned out, especially the fade which was a mess to get correct. The colors are tied to my HR zones. Hope it inspires someone. Happy to answer any questions!

Hey everyone, I got tired of constantly checking when World Cup matches are on and which channel they're showing on, so I built a little site that lets you create your own personalized calendar for the tournament. The idea: you pick your teams, add it to your Google/Apple/Outlook calendar in one click, and then you're done. Kickoff times confirm themselves, the knockout rounds fill in as they're decided, and the TV channel is shown on each match. It's a free personal project, no account to...

Hey everyone, A few months ago I barely knew what a Web Worker was. Today I finally deployed my first real project. Like a lot of players, I've always hit a wall calculating more than 5 moves ahead in faster games. Standard puzzles don't really train that; you're always looking at the board, which isn't how real calculation works. So I built Horizon Chess to fix it. Completely free, no ads, no backend at all, just Stockfish.js running in a Web Worker, Chess.js for move validation, and Ches...

i run this platform ; i'm the CMO, focus on the CMO because we are going to need that detail. and i have a CTO Now, if you look for CTO, you'll find this: "The CTO’s responsibilities include the following: developing and adapting the organization’s ICT strategy, balancing business and technology strategy in order to obtain useful information for strategic decision-making, maintaining the more technical culture of the company, and directing and supervising the company’s technical engin...

over the last few years after getting a masters degree from ASU and also working in the tech industry, i realised that in the whole world wide web, we could categorize most of the data into two domains - facts and opinions. facts dont change and opinions are scattered all across the web. i wanted one place where we index all the user's opinions and make a thoughtverse which could be really valuable..coz it would technically be the db of growing thoughts. from this i realised one key point that, ...

Hey everyone, I wanted a simple screen time tracker that keeps all my data local and private. So I built ScreenOwl 🦉. It runs locally on Windows and: Tracks app/site usage (stores everything in local SQLite). Generates a daily timelapse video of your screen. Writes a daily productivity summary using Gemini AI. Lets you block distracting apps/sites when you hit a limit. 🎁 No account or credit card required — the app includes a 14-day free Pro trial immediately upon installat...

spending too much time on social medias while I'm supposed to hustle when I'm on one of them my front camera slides down out of the MacBook notch and shows me my own face no blocking, no streaks, nothing to turn off, just me, looking at me, mid-scroll. very stupid but catching your own blank zombie face while you're three reels deep is really hard to ignore

I have some ideas I want to execute on, but I'm so exhausted from the rat race. Any advice on how you motivated yourself or prioritized your side project? It would be much appreciated, I would love to hear your story if you feel like sharing!
