Re:Fakecloud: Local AWS cloud emulator for integration tests on Sunday September 27, 2026 @11:21AM (#49867422)
I'm launching something in that space this week - if you're interested in trying one of those out, feel free drop me a message via my website (in bio) :)
This is neat!

A few months back I ended up building a RDC Server in Golang (i.e. no Windows required!) entirely with Claude, which was a fun experiment.

I ended up fronting that with GitHub Auth (purely for rate limiting purposes, since it's bandwidth intensive), but I've built it in such a way that it surfaces/renders any arbitrary binary on the RDC side. In my case, I ended up just fronting it with a Snake binary, but it's been fun to experiment and push the bounds somewhat.

I should really think about open sourcing it - in my case it was an experiment to see how far I could push Claude that turned out pretty great tbh

> Would love to try it out - is there a live demo link?

Yeah there is, got a little lost in the formatting, but you can try the game out here: https://arena.ibuildstuff.eu

> How much of the code did you write vs. Claude?

Claude Code wrote all of it, I haven't written a single line of code here, only prompted/driven Claude (and configured deployment/a GitHub app/DNS etc). There's a breakdown of tasks at the bottom of the page ("how it was built")

> What was the hardest part to get Claude to help with? (I imagine real-time networking/WebSockets was tricky)

Definitely WebSockets - mostly in terms of debugging issues when a client disconnected and the instance was running for an extended period. After a couple of minor bug fixes I explicitly asked Claude "Please review the WebSockets code for any issues and fix those" which fixed a couple of issues

> - Any major bugs or issues that Claude couldn't solve?

Primarily around map generation, it needed a bunch of help there - it tends to spawn the turrets inside of walls, didn't take vertical elevation into account (so you could pass through a wall/under a block) - and when I asked it to generate a non-polygon level (which I've not yet pushed support for) it created a star-shape, with the bases outside of it.

Also I intentionally opted to avoid getting Claude to write tests for this, I've not looked into it, since I suspect writing a test suite for WebGL & WebSockets is _probably_ a lot more effort - and doing this by hand has allowed me to play-test this whilst Claude focused on implementing it

It's been a fun experience though!

Show HN: I built a 3D web-based multiplayer game with Claude Code

Hey HN!I’ve shown this to a few people and thought folks here may be interested too.I’ve been using Claude for a while now, and wanted to see how far I could really push it without writing a single line of code.I ended up building a 3D web-based multiplayer game, inspired by FutureCop: LAPD (on the PS1, specifically the Precinct Assault multiplayer mode -...

Location: Berlin, Germany.

Remote: Yes

Willing to relocate: _maybe_ within the EU

Technologies: Golang (preferred) but I’ve worked in C#/Java/JavaScript/Rust/Swift and plenty of others over the years. Plus Azure, AWS. etc.

Résumé/CV: (available via email)

Fresh off a career break, now looking for my next role. My last job was at HashiCorp, where I led the development of the Azure Provider for Terraform. I’m a product engineer and work on whatever part is necessary across the stack to get the job done. As teams go, I prefer small ones, that work in a close-knit way - but I’m open to interesting challenges.
