Particlr
Particlr is a particle-effect editor that runs in the browser, paired with an MIT-licensed runtime that plays the effects back inside a game. You author an effect, export one versioned `.prt` JSON file, and the runtime renders it in PixiJS exactly as the editor previewed it, because the editor previews through that same runtime. Parity is treated as an invariant and checked by golden-frame tests in CI at pixel tolerance zero. 57 CC0 presets ship as editable starting points.
