Browser-based tools for audio, pixel art, worldbuilding and more — free, no install, no sign-up.
What we build
Featured Tools
Audio
Neural Groovebox
Build loops, sculpt your sound, and lay down electronic acid, 808, pluck and reese beats. Exports to WAV and MIDI.
TTRPG
NPC Generator
Instant NPCs for D&D, Pathfinder, Call of Cthulhu, Shadowrun and more — from ancient settings to the far future. Drop them straight into your session.
Pixel Art
JagFree
A pixel-art converter that obliterates jaggies. Flatten palettes to 8 or 16 colours and downscale sprites to 8, 16, 32 or 64 px wide.
Our aim
Built to help indie devs ship
We’re a tiny game studio, and along the way we’ve built a pile of small tools to solve our own problems — generating chiptunes, cleaning sprite sheets, rolling NPCs, flattening pixel art. They’re all free, they run entirely in your browser, and now they live here for every other indie developer to use.
No accounts. No paywalls. No uploads to a server. Just open a tab and go.
Audio
ChipForge
Generate chiptunes on the fly. Pick a key, scale, vibe and BPM, then export to MIDI and WAV for your game’s soundtrack.
