Our verdict on particlr

For web developers creating 2D particle effects, particlr combines a browser-based editor with an MIT-licensed runtime. It exports effects as JSON .prt documents and offers deterministic playback through adapters for PixiJS, Three.js, and Phaser 4. The Free plan covers core authoring, host parameters, and a library of 71 CC0 presets, with unlimited import and export. That makes it a practical fit for developers who want to edit effects without leaving the browser and whose projects use one of the listed runtimes.

The clearest distinction is the split between core authoring and advanced modules. Free includes tools for emission, curves, velocity, gravity, drag, noise, blending, and collision. Premium adds sub-emitters, trails and ribbons, attractors, texture masks, dissolve, and a sheet packer; the product description also identifies baked-image export as part of the premium key. The published price is a one-time $10 early-bird Premium key, with the vendor noting that it becomes $20 after beta. Buyers who need those advanced effects should account for the paid key, while a project limited to the core modules can start with Free.

Platform and runtime fit matter more than breadth here: particlr is listed for web use, with adapters for PixiJS, Three.js, and Phaser 4. Its .prt JSON format supports importing and exporting effect documents, and PNG is also listed as an export format. The runtime is open source and MIT-licensed, which suits teams that want to integrate playback into a supported engine. Choose particlr if browser editing and those runtime targets match your workflow; look elsewhere if you need a desktop editor or an adapter for a runtime outside that set.
