Food waste is a full time job

TLDR: Find the the project that makes you want to persevere Hi guys long time lurker here, I've been deliberating on posting for a long time now but I thought this was a good time as any to get something out there. I have been working my mobile app for about a year now. Mostly because, as is usual, the scope balloons beyond what would have probably been the absolute minimum. I'm a software engineer by trade, so my coding graveyard is numerous and filled with projects that I start, furiou...

I built a Chrome extension that writes your X & Threads replies (and posts) in your own voice one click

Hey r/SideProject 👋 I do a lot of my growth on X and Threads through replies, but staring at a blank reply box 50 times a day was burning me out. And most AI reply tools I tried felt like bots generic "Great point!" replies everyone can smell. So I built Cue. It lives inside X and Threads. You click one button on a post and get 3 on-topic replies written in your voice (you paste a few of your own posts once, and it mirrors your style). It also writes full original posts fr...

I built a free WordPress scanner (security, performance, accessibility, SEO)

Hey I manage several WordPress sites and got tired of juggling WPScan, Lighthouse, and various SEO tools just to get a full picture of what's going on with a site. So I built Pulse WP, a free tool that runs a complete audit in under a minute: security vulnerabilities (CVE database updated every 12h), performance, accessibility, and SEO. Would love feedback from people who actually maintain WP sites. Plugin with more features and better experience is on the way. Scan your WordPress 👉 ...

I built a tool that scores company culture so you can tell if you'd actually fit before taking the job

Spent the last while building this. The idea came from watching people (me included) take a job for the title and the money, then realize a few months in that the way the team actually operates is what drives you up the wall. It scores a company's culture across a handful of dimensions, and after a short quiz on how you like to work, it shows how you'd personally fit. You see your result for free with no signup wall (literally shipped that change this morning). Link if you want to try it: h...

I’m building a website that will eventually become a collection of useful browser-based tools, similar to iLovePDF but covering many different categories. The goal is simple: No downloads No accounts Fast and mobile-friendly Free to use I’m researching what people actually need before building more tools.

Built a freelance rate calculator that shows the number most freelancers never calculate

I kept seeing people ask "how do I set my hourly rate" and the answer was always "divide your income goal by 2,080 hours." That number is wrong, it ignores taxes, non-billable time, and overhead. So I built something that does it properly. You put in your take-home target, tax rate, business expenses, and what percentage of your hours are actually billable. It spits out: - Survival Rate: your absolute floor - Growth Rate: what to charge to also save and reinvest - Per...

I built a RAG chatbot grounded in primary Hindu scriptures, with verse-level citations, all out of personal curiosity

Hey everyone, For the past few months I have been building a side project that came out of pure curiosity. I study non-duality, Advaita and Shakta philosophy, and I kept running into a problem, the answers I wanted were scattered across many scriptures and no single text or search gave me what I needed. So I used Claude Code to build a RAG system over scriptures that are copyright free or raw source texts. It does hybrid search, vector plus keyword, reranks the results, and returns the actua...

I spent the last 18 months building what is probably one of the most comprehensive analytics and alerts platforms for Polymarket

Launched a home inventory app in March and still working on it every spare minute

I got fed up looking for a decent home inventory app. The ones on the App Store either want your credit card before you've added anything, cap your items to push you onto a paid plan, or look like they haven't been updated since iOS 6. None of them feel like real iPhone apps. So I started building one that did, mostly because I wanted it for myself. My whole house is in it now and I use it every day. additem.to lets you track what you own and where it is. Photos, serial numbers, locations, c...

Looking for honest feedback for my first app!

Hi everyone, I’ve been thinking about an app idea for a long time and recently started turning it into a small prototype.

I’m not sharing all the details publicly yet, but I’m trying to understand whether the basic concept feels clear and useful from the outsid...

Built a niche job board for independent coffee shops. 800 monthly visitors, no idea what to do next.

Built it in a weekend, posted about it in a few coffee industry groups, and it slowly started getting traffic at 800 monthly visitors now, mostly organic (no paid acquisition at all) The problem is i built the product but not the business around it. no monetisation, no way to contact the visitors who are coming.

Cate – Open-source canvas IDE for agentic coding workflows

We built Cate, an open-source canvas IDE for agentic workflows. It started from a simple problem: most IDEs were built for writing code by hand. Terminal's were displayed via tabs or in a stack (VSCode) Cate lets you place editors, terminals, browsers, docs, Git worktrees on one infinite canvas organised in workspaces. Since the first version, we’ve been improving: performance, worktrees, terminal behavior, command palette, and agent workflows. GitHub: https://github.com/0-AI-UG/cate ...

I loved 2048, but always wanted a proper puzzle campaign. So I built "Gridlocks"—a version with levels, anchors, and modifiers.

So, I spent the last few months building Gridlocks . Instead of just an endless grid, I wanted to create something that forces you to think three steps ahead. Here is what I added to the classic formula: Campaign Mode: 22 hand-crafted levels across 5 stages. Each stage introduces unique ...

Peptide Calculator I wish existed when I started: simple dosing + scheduling on 150 peptides

Hey r/SideProject , This started as a personal problem. I was running 2-3 peptides at once, each on a different schedule, different doses, and some in a "loading" phase at higher frequency with lower dosage. I kept losing track of what to take when, and worse, what that dose actually was in syringe units. Redoing the reconstitution math half-asleep before a morning injection is exactly how people mess up a dose. And injecting yourself is genuinely scary the first few times. Get th...

built a language learning app prototype where your progress gradually builds a cozy little town. Do you think that actually helps people stay motivated, or is it just a gimmick?"

So yeah, I’ve been using Duolingo on and off for years, and my cycle is pretty much always the same. I study for a while, then I miss a few days, then I lose my streak, feel bad about it, and eventually stop using the app altogether. At some point, I realized I wasn’t quitting because learning the language was hard. I was quitting because the pressure of keeping a streak made it feel more like a duty than a hobby. So recently, I’ve been building a small language-learning prototype on weekend...

The app finally launched on the App Store this week. I’m not posting this to sell anything. I’m genuinely curious: What’...

I built a tool that roasts you when you miss your own startup deadlines. Here's why I made it.

I kept starting things and never finishing them. Not because the ideas were bad. I'd just slowly stop showing up. Miss a deadline, feel bad, miss another, feel worse, close the laptop. Three projects in a row died that way. Tried accountability partners. Felt awkward asking someone to chase me. Tried Notion trackers. Stopped opening them after two weeks. So I built Grillr. You put in your business idea. It breaks it down into a task plan with real deadlines. When you miss one, you su...

Hey r/SideProject , For the past few years I’ve been struggling with sugar addiction. I’d start a “no sugar” streak, feel great for a week, then cave in after seeing desserts or stressed snacking.

It’s a simple menu bar app that shows your newest and recently edited files right away, with a small clipboard section for saving useful bits of text.

I built a sacred space on the internet for sincere music recommendations (I just hit 83 weekly users in 5 weeks!)

Hi, I'm Julius, a computer science major from Sweden. I had this really simple idea that I've never seen on the internet before. The concept for the website is: each week you share one song recommendation and a text about what it means to you, like a personal story or just your thoughts on the track. And in return, you get five back. I've noticed that when a song recommendation has a story, it immediately becomes much more interesting and moving to listen to. And so far, the texts people wri...

I built Cliff - a tool that shows what your startup equity offer is actually worth

When I was evaluating job offers, I got frustrated with how misleading startup equity can be. The big “X% equity” or “$Y options at $Z valuation” sounds amazing on paper, but after dilution, liquidation preferences, vesting, taxes, and the reality that most startups don’t exit for unicorn money.. the actual take-home is often way lower. So I built Cliff - an interactive equity decision toolkit that models realistic outcomes. What it does: • Turns your offer letter or cap table numbers into a...
