Pincel

Pincel is a pixel-art and image editor in one app. Pixel mode makes sprites, tilemaps and animations and reads and writes the .aseprite format. Image mode edits layered images — photos, screenshots, mockups — with brushes, selections, effects and adjustments. The mode follows the file you open. It runs as an installable web app and as a desktop app.

Try it

• In the browser: https://pincel.amigo-labs.dev/app
• Desktop: installers for Windows, macOS and Linux are on the latest release. The installed app updates itself.

Development

You need Rust (stable) with the wasm32-unknown-unknown target, wasm-pack, Node 22 and pnpm 10. The desktop shell also needs the Tauri 2 prerequisites.

cd ui
pnpm wasm:build     # first: the UI links the generated wasm packages
pnpm install
pnpm dev            # http://localhost:5173/app/
pnpm tauri:dev      # the desktop app

Tests and lints: cargo test, cargo clippy and pnpm lint && pnpm check && pnpm build && pnpm test:e2e, with the exact crate lists in AGENTS.md §10.
