I built an invoicing tool for freelancers who bill in multiple currencies and never know what they actually earned

Solo dev here. I freelance with clients in different countries and kept hitting the same wall: quote in one currency, get paid in another, then stare at a spreadsheet trying to figure out what I actually earned after FX and taxes. So I built 1account - invoicing focused on that exact workflow. What it does: - Invoices in 35+ currencies, professional PDFs - Collect via Stripe, bank transfer, or crypto (NOWPayments) - One dashboard that converts everything to your base currency and, the part I car...

Launched on Product Hunt with 0 followers. Finished #3. Here’s what actually happened

I built a self-hosted AI memory layer on Cloudflare because I was tired of re-explaining context to Claude every session. Open sourced it. Then decided to launch on Product Hunt. Three weeks before launch I had 0 stars. I spent that time posting on Reddit, shipping features, and building an Obsidian plugin. Got to ~90 stars before touching PH. The launch amplified that momentum, it didn’t create it. I got lucky with my hunter. fmerian has 67K PH followers and hunted Mastra. He suggested laun...

New week, new challenges! What are you building these days? 🚀

Hello everyone, and have a great week ahead! I’m building NextIsOnMe , a social app aimed at fixing the broken dynamic of modern networking and dating. The concept is "Treat and Meet", using a simple real-world gesture (like a coffee or a drink) to fast-track genuine human connections and get people off their screens and into local venues. We are now trying to break the "chicken-and-egg" problem that most social apps face. Last week we focused successfully on user a...

My girlfriend kept getting headaches from not drinking enough water, so I built a Mac app that floods her screen until she does

I built this for my girlfriend. She gets headaches, the kind that wipe out a whole afternoon, and almost every time I'd ask her the same question: how much water have you had today. The answer was always "not enough." Reminders didn't work. She'd swipe the notification away and forget before she'd even put her phone down. So I built something harder to ignore. Drink or Drown is a hydration app for Mac. When it's time to drink, a water shader rises over a live capture of your screen u...

Need advice on what next for the projects that I’m building

I’m a software engineer who builds and launches web and iOS side projects. The building part is fun, but I’m struggling with everything after launch. How did you: • Get your first 10–100 users? • Collect honest feedback from strangers? • Validate ideas before spending months building? • Learn customer discovery, distribution, and growth? My biggest challenge isn’t building products, it’s finding people who care enough to use them. [l...

Built a Side Project: A Security-First Cloud Platform

I've been building a side project called Krova (krova.cloud) for the past few months. The idea started from a simple frustration: most cloud platforms expose a lot of infrastructure by default, and securing everything properly can become its own full-time job. So I decided to take a different approach: 🔒 No public IPs by default 🛡️ Isolated microVMs with dedicated kernels (no shared kernel) 💾 Automated backups ⚡ 1:1 memory-to-disk ratio for predictable resources The goal is to make s...

My side project went viral, then someone cloned the source and shared it publicly

A few days ago, my small macOS desktop cat app unexpectedly went viral after a tech creator posted about it. The video passed 500K views overnight, which was exciting until I saw someone in the comments saying they had the source code and would share it. (You can check the first image in the video) He also posted a GitHub repo link. When I opened it, it looked like a copied/modified version of my project files, publicly uploaded, with what seemed to be their own license key flow. I left a ...

Launching a product on PH today, would really appreciate your support

Hey everyone, we just launched Alfa on Product Hunt today. Alfa is an agentic content engine for SaaS teams focused on GEO and keyword research. We built it because most AI writing tools jump straight to drafting and skip the hardest part of SEO: SERP analysis, search intent, keyword clustering, and figuring out what actually deserves to rank or get cited in AI answers. If the launch resonates, I’d really appreciate your support on Product Hunt today. Still very early, so I’d genuinely lov...

I built an AI speaking coach that scores your filler words and pacing — roast it

I kept saying "um" and "like" in presentations and never knew how bad it was until someone pointed it out. So I built Offscript: you record yourself talking for 60 seconds, and it gives you instant feedback — filler count, pace, clarity, energy — plus coach notes on what to fix. It's early and rough. I'd genuinely rather you find the problems now. What would make this actually useful to you (or what makes it useless)? Link in comments so this doesn't get auto-filtered. ...

Things I wish I knew before making a mobile app

Just launched my first iOS app and honestly the building part was the easy part. Here's what nobody told me: Apple's app review will humble you. I got rejected multiple times for things I never even considered — paywall disclosure requirements, IAP configuration issues, entitlement mismatches. Each rejection adds days to your timeline. Third party API approvals take forever. I built around Plaid for bank connectivity and getting approved for production access took way longer than expected. Y...

I built an app where strangers write stories together one section at a time. Just shipped eBook export that credits every co-author.

I'm the maker, building this solo. Wanted to share where it's at and get some feedback. It's called Half Quill. The idea: a few words from you, a few words from a stranger, and every day a story grows. People take turns writing sections of a story, and you can't write two in a row, so it's always a back-and-forth with someone you've never met. Low stakes, playful, a bit of a doomscroll replacement that makes something instead of just consuming. The thing I shipped this weekend: you can now d...

I Made A Free Co-op Survival Game To Play With My Kids

Background: I love playing games with my family. We spent hours on 99 Nights in the Forest over the recent holidays, and after that we kept looking for something else we could all play together. Something fun, easy to jump into, but still challenging enough to keep us hooked. I also had to learn Claude Code for work, so I thought: why not use that as an excuse to try making a game? That turned into Protect The Bears , a free browser-based co-op survival defense game. You can play it ...

I got tired of Al making stuff up about my PDFs, so I built something that actually cites its sources

so i kept using chatgpt to ask questions about my pdfs and notes, and half the time i couldn't tell if it actually read the doc or just made something up that sounded right. that bugged me enough to build my own thing over the last few weeks. you upload a pdf (or word, csv, image, or just paste a link), ask whatever you want, and it answers using only what's in your file - and it shows the exact page it pulled the answer from, so you can check. if the answer isn't in the doc, it just tells you...

Diary on a whiteboard to juggle work and life

Hi All! Building a visual planner to juggle work and life in one continuous view. You can see where things stand, what needs your attention, and what's coming up, instead of holding it all in your head. Started as a physical whiteboard setup I used for years. Digitalised it when travel made the whiteboard impractical and nothing online matched.
