Superpowers

Homonym warning. superpowers also exists in ../agentic-tooling-wiki — Jesse Vincent‘s agent-skills framework. Unrelated projects sharing a name; the slug collision is intentional and the two pages must not be merged. (Recorded 2026-07-28 quality cycle.)

A downloadable, open-source HTML5 game-development engine + IDE by Sparklin Labs, distinctive for real-time collaboration — multiple developers editing the same project simultaneously through the browser (“Google Docs for game dev”), great for jams or long-term co-development. TypeScript (~86%), ISC licensed, self-hostable (with optional password-protected collaborative sessions).

What it is

• Engine-agnostic core + extensions. The core is a collaborative project platform; specialized extensions sit on top — Superpowers Game (TypeScript via Three.js, 2D and 3D), a web-project mode (Pug/Stylus), and even a LÖVE 2D export. So it’s as much a collaborative editor shell as an engine.
• Status: archived (5 Mar 2021), unmaintained. The spoke’s first defunct/historical engine.

Why it matters to the spoke — two new axes

• Real-time collaboration (new axis). Every other engine here is a single-developer-project tool with collaboration bolted on via external VCS. Superpowers made simultaneous multi-user editing the core design — a distinctive (and, in 2014–2021, early) bet. Worth watching whether modern engines revisit it as cloud/collab tooling matures.
• Liveness as a dimension (new). Being archived since 2021 makes it the first engine here that is no longer maintained — a reminder that the field’s roster includes dead-but-instructive projects, not only active ones. Its collaboration idea outlived its codebase.
