side project that actually started as a personal frustration

been doing handyman work for a while. tools kept disappearing. not stolen. just lost. borrowed. left behind. it was costing me time and money. so i built a simple inventory tracker for myself. just something to log tools, track where they are, and remind me if something has been out for too long. its pretty basic. no fancy ai or anything. just a tool that solves a problem i had. now im wondering if other handymen and small crews have the same problem. might be worth turning this into somet...

HTML Forms - Straight to Email (keep your side projects organized)

Like most in this subreddit I create a ton of sites to gauge interest and with AI agents my increase in sites published per month has skyrocketed. The only annoying thing: setting up email for contact forms and keeping everything organized... So, I created https://html.contact/ 'Paste one URL into your form and receive submissions in your inbox. No server. No plugin. No gated features. Everything is included from the start. Upgrade only when it's worth it.' I don't gate all the paid fe...

I built an app that reduces noise and increase signal in your life

What if most of the things you do daily aren't actually moving you forward in life? What if you have more noise than signal? Since I listened to a podcast episode last year discussing how Steve Jobs viewed productivity through the lens of a signal-to-noise ratio, where he aimed for an 80/20 ratio (80% signal and 20% noise). This has been at the back of my mind ever since and I just find the concept so fascinating [See clip from the podcast here: https://www.youtube.com/watch?v=SLkCmDGtidg ...

I built a tool that turns two URLs into a finished client proposal. Looking for my first testers before launch.

I am a solo founder. For the last year I was cold emailing agencies to sell automation work, and the part I hated most was writing the proposals. Hours per prospect, and half of them ghosted me anyway. So I built a thing for myself. Paste my site and the prospect's site, and it reads both and writes a full branded proposal in a couple of minutes. Their logo, their colours, their services, and the gaps on their current site, all pulled from their actual website. Then I can edit every word, pick...

I built HomeSight – free interactive map of home values and rent trends across 26K US ZIP codes and England & Wales postcodes

HomeSight started as a personal research tool — now it covers both the US and UK housing markets. Pick any US ZIP code or England & Wales postcode sector and see: → 1, 3, 5, 10, and 20-year home value appreciation → Rent trends and median sale prices → New listings over time → Top-appreciating areas ranked within any metro or region The motivation : city and regional averages hide massive local variation. In Dallas, one ZIP appreciated 26% over 3 years while a neighboring ZI...

What's the biggest time-saver you've implemented in your project?

Not necessarily a too, but just any change that freed up time. Maybe it was automating a task, simplifying a workflow, or organizing inventory better. Or perhaps a habit change? What ended up giving you the biggest return on your time?

I built a Mac app where you point at your screen and talk, and your AI coding agent makes the change without you touching your keyboard

My best friend and I have been building this and I'm at the point where I want eyes on it from people who ship their own stuff. It's a Mac app called Zerro. You hit a hotkey, drag to frame any part of your screen, and talk while pointing your cursor at things: "make this header sticky, change this button to teal." In Dev Mode it turns that into a repo-scoped instruction and hands it to your own coding agent (Claude Code, Codex, or Cursor) running on your project. The agent edits the ...

Built and refined my adhd todo app after feedback from real people

Hi r/SideProject I first launched ikoi 2 months ago. What it is. And how it's different from other productivity apps. 1. Energy gating - Every task is assigned a energy rating. Low, Medium, High. Tasks are gated by energy so when have you low energy you don't need to see tasks which require high energy. That just clogs up your mind. 2. Spoon theory built in - You can also set effort (spoons) required per task and set a daily budget. If your day has tasks what exceed that, you...

Thought I was days from a beta. Four months later my pantry app is finally live.

Floated this idea here a few months ago. At the time I was sure I was a few days from a working beta. It took four more months. Anyway, it's real now and in closed beta, and I'm not here to re-pitch the concept. I want to talk about the part that almost sank it, because it never shows up in a demo. Quick orient: Pantro runs the whole kitchen loop in one place. What you have, recipes that fit it, a shopping list for what's missing, then the pantry topped back up after you shop. Now the part t...

Made an extension that makes YouTube 100x easier to use.

Hey everyone, I wanted to share a small extension I’ve been building called PopupX . The original reason I made it was pretty simple: I use YouTube constantly, but I kept getting annoyed by small bits of friction. Sometimes I just wanted to pop out a video quickly, search without losing my current page, or hide parts of the UI that were distracting. So I built an extension around those workflows. A few things it does: Double-click a video to instantly open it in a pop-out player Al...

Adding a fourth AI provider to my side project feels like a chore now

My side project started with one provider for text. Then I added a second one because it was better at a specific kind of rewriting. Then I bolted on image generation from a third place. Three providers, three SDKs, three API keys in my env file, three billing dashboards I keep forgetting to check until something weird shows up on a card statement. It was fine until I started thinking about adding video. Not even committing to it, just playing with the idea. The thought of a fourth SDK, a four...

Hey yall, I’ve been trying to build autonomous AI agents using MCP lately, but I noticed a destructive issue: it’s incredibly easy to accidentally give an agent full access to your root directory, leak hardcoded API keys in configs, or forget manual approval gates on destructive tools. Since I couldn't find a quick way to solve this, I spent my past week building a lightweight Python CLI and GitHub Action called agentlint . It statically scans your configs for: Broad filesystem expoes...

Six months, multiple projects. I’m exhausted.

This is more of a soul dump than anything else. I’m not a programmer. I’ve always been someone who likes building things and learning new skills. About six months ago, I decided to start building apps. In January, I started working on a large app for motorcyclists. I finished it in March. Within two months, it grew to more than 7,000 users. Even today, despite the fact that I stopped actively working on it about a month ago, it still has more than 1,500 daily active users. I made one huge ...

My Watch Later has like 2,000+ videos in it, and honestly I try not to save more, for exactly that reason. The bigger it gets the less chance I have of finding anything in it again. Anyway, I was heading out on a bike ride the other day and wanted a podcast for the road. 2 hour ride ahead, and all I could dig out by scrolling was a couple of 20 minute videos. That was the moment. I just wanted to filter the thing down to podcasts and hit play. So I built an extension that does that. You run ...

What 8 months of AI-handled intake calls actually looked like

An early stage law firm I work with had a front office problem relating to missed calls. The founder put it plainly: "a number of potential clients were lost, especially in time-sensitive matters where people move on quickly if they don't reach someone live." The solution I proposed was an AI voice agent to cover the overflow and after-hours calls, as those were the lowest risk and were being missed anyway. The goal was to have it run their intake process end to end. That meant it ...

Google Flights hides the cheapest way to travel Europe — so I built a tool that finds it

Hey r/SideProject , Solo dev, this is my project after a few months of nights-and-weekends work. The problem: the cheapest way to fly around Europe is usually not one ticket — it's chaining separate low-cost flights (Ryanair, Wizz, Volotea, easyJet, Transavia…) with self-connections. Google Flights and Skyscanner hide these because they only show single through-fares. Finding them by hand = testing dozens of connecting airports and dates.
