Open-source RSVP app using Supabase and Flutter
I'm doing a new Show HN[1] as we have now made this open source, and got some interest in comments in the past few days. We initially built this app for some friends in a co-living community - they were using pen and paper to track who's attending lunch - but it was error-prone. First I suggested a shared Google Sheets or Calendar, but that was also messy to maintain. Eventually, I developed something just for them. They used it for a couple of years, they loved it and wanted to use it for more things, too. So I took all the learnings from what was now the MVP, and with some friends we now…

Open sourcing Harmonic, my Android Hacker News client2023 · github.com · ▲305Hey HN! I'm the developer of one of the most popular Android clients for HN, Harmonic for Hacker News. Over the years I have recieved many requests to open source the app which I am finally doing - sorry about taking so long :) Having been very busy working on my PhD during the last two years - Harmonic has not recieved the attention it deserves. I therefore hope that open sourcing it can give it a new lease on life. I also hope that by posting here many of the nice people who have reached out to me will notice that the app is finally open source. I'm also happy to answer questions about the…
- LSLists.sh – A Microblog for Lists2022 · lists.sh · ▲271
Greetings, creator here! I've been working on a new blogging platform specifically for lists on and off for a few months now and I'm excited to officially announce its launch. After seeing https://charm.sh a few months ago, I've been enamored by the idea of SSH apps. I decided that a blogging platform focused on developers could be the perfect use case for an SSH app. Also, I love writing lists. I think restricting writing to a set of lists can really help improve clarity in thought. The goal of this blogging platform is to make it simple to use the tools you love to write and…

Support.dev – a non-trivial Vue and Supabase app2024 · github.com · ▲55I built this tool about a year ago to get really good at the supabase ecosystem. We were trying to raise money on the idea, but that didn't occur, so I wanted to open-source it, as I would love to give back to the commmunity. It allows you to invite friends and family to be helpers for child-care, meals, and transportation, and then you can create an event and they will get auto-invited to it and can choose to support you. It is using vue on the frontend and then supabase on the backend for auth, database, realtime, storage, and edge functions. Anyway, I hope someone finds it useful, there…
I made a Flutter app for loneliness. 14000 min of voice messages later:2024 · main.d1lmgoealm7rq0.amplifyapp.com · ▲35I hope you are doing better today than yesterday. (TLDR in the comments; or enjoy my story :) ) Why: About 11 months ago, I launched my app for the first time on Reddit's r/lonely because I had previously experienced loneliness myself during grad school. I wanted to reach out to people going through similar experiences by providing them with what would’ve helped me in the past. I felt this was an important mission for me and a much more rewarding one than my day job that I quit my job to work on the app full-time. It was necessary because I did not come from a programming background. I…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…
