Limitless Lab is open: 20 free things to poke

2026-10-09 · LIMITLESS LAB · 3 min read

Have you ever had a list of “little things I’d love to build” that just keeps getting longer? Mine was HUGE. Tiny games, physics toys, that one tool I keep googling for. So I stopped adding to the list and built a place to put them all. Say hi to Limitless Lab!

It’s 20 free things that run right in your browser. No installs, no accounts, no ads. And it works on your phone (honestly, that’s where I test it first).

Three phone screens side by side: the home pages of Limitless Arcade, Limitless Lab and Limitless Workshop, each with a short intro, tag filters and a list of items to pick — **The three wings**

Three wings

🎮 Arcade: small games. Timeless Mini (yes, a tiny Timeless!), Orbit Sling, Daily Grid, Slime Dash, Gravity Golf and Brick Breaker+.
🔬 Lab: science and maths you can poke. A neural network learning live, Fourier drawings, chaos pendulums, flocking birds, gravity, waves and an endless fractal zoom.
🧰 Workshop: free tools for makers. Shrink images, make game sound effects, build colour palettes, slice sprite sheets, make app icons and QR codes.

Four phone screens from the Arcade: the title screens of Timeless Mini, Orbit Sling, Gravity Golf with its twelve holes, and Brick Breaker+ — **Arcade**

Four phone screens from the Lab: the Mandelbrot set in Fractal Zoom, a neural network sorting red and blue dots, waves passing through a double slit in Ripple Tank, and a heart drawn by spinning circles in Fourier Draw — **Lab**

Private on purpose

This was a big one for me. Nothing you do ever leaves your device.

The tools never upload your files. Your images get squished right there in your browser.
Saves stay on your device, and you can export, import or delete them whenever you want.
The pages can’t load stuff from other sites. The only exception is a cookie-free visit counter, so I know if anyone shows up!

Three phone screens from the Workshop: Palette Lab with five colour swatches and lock buttons, SFX Maker showing a sound wave with presets like Coin, Jump and Laser, and Icon Maker asking you to drop in a picture — **Workshop**

Why I built it

Have you ever read about something cool, like how a neural network learns or why a double pendulum goes completely bonkers, and the explanation was just a wall of maths? Same. I learn by poking things. Drag it, break it, change one number and watch what happens. That’s when it finally clicks.

So that’s the whole point of Limitless Lab:

Learn by playing. Every sim is something you can touch, not just read about. Fourier series, gradient descent, chaos, flocking, waves, gravity.
Free, for everyone. No paywall, no sign-up, no “premium” version. If you’re curious, you’re in.
Fun first. If it’s not fun to mess around with, nobody sticks around long enough to learn anything. (Including me.)
Works anywhere. A school Chromebook, an old phone on the bus, whatever you’ve got.

You don’t need to understand the maths to start. Play first. The “ohhh, that’s why” comes on its own.

The games and tools come from the same place. The Arcade is little bite-sized games that each show off one neat idea (real gravity, real bounce angles), and the Workshop is the free tools I wish I’d had when I started making games.

What’s next

More items! On the list: Stack Tower, Snake Evolved, a Game of Life lab, a pathfinding visualiser, a regex tester and a pixel art scaler. I also want a way to install it like an app, so it works offline too.

Go poke something and tell me what breaks, or what you want next, on Discord!
