Show HN: Paintpot – Kid-friendly MSPaint clone for Linux

deposittag — Sat, 14 Nov 2026 21:56:40 +0000

Most of the alternatives diverged from the true fun of MSPaint that I had as a child. My children also seem to enjoy this. The closest existing project was "Drawing" on Linux, but I felt it couldn't decide if it was a vector or a raster editor, and this confused my kids, and made good fill pours difficult.

Features added beyond original Paint:

- Draw circles starting from the center.

- OKLCH Palette

- Visible pixel grid when zoomed in.

- Resizing canvas never destroys pixels.

- Builds on Linux and Windows.

- Written in rust.

Show HN: Domino Rally – design in 2D, watch in 3D

orgiggly-dave — Sat, 14 Nov 2026 21:38:51 +0000

This is a free to play, no sign up required domino rally simulator. You design them with the editor, and then run them in the 3D player. The from-behind "Chase" view is best.

My mum helped develop it - she submitted issue reports direct from the app itself (make it possible to bend the domino tracks, make the playback controls disappear while mouse inactive, add like buttons to the showcase, let me change the backdrop, etc) and the Claude Code session running in the cloud watched, fixed them and on my approval, pushed them live.

I've been making a lot of apps in various sessions which share the same repo. One of them https://www.orgiggly.com/david/aurora (an atmospheric musical loop generator) was plundered to generate a unique soundtrack for each rally (seeded by its name) - which is exactly how the orgiggly platform I built is supposed to work - each app created can make contributions to the next one.

Show HN: DownForReal – Kuma Hosted from 3 regions

hodder — Sat, 14 Nov 2026 18:43:21 +0000

I use Kuma for a few microservices I’ve built. It’s a simple open source tool for monitoring APIs, ports, websites etc if they are down.

The issue I get is that they are hosted on your own infrastructure, so it doesn’t do you a whole lot of good if your site is down and it takes your Kuma down with it. This also leads to a bunch of false notifications which are annoying.

From what I can tell, people in the GitHub comments are looking for hosted Kuma.

I built DownForReal (largely with LLMs) but what it does is it hosts Kuma and if Kuma is reporting the service down, probes from US, Frankfurt, and Singapore are sent to confirm the outage (looking for 2 out of 3 of the regions).

I’m asking $10 a month or $75 a year.

I’m really just launching this as a service bc I built it for myself.

There is also a simple importer for uptimerobot exports.
