Open a capsule in your browser

Drop any .cap package below. It is unzipped and inspected entirely on your device — nothing is uploaded — using the same contract files every reactor reads. Then serve it live: a service worker answers its routes right here.

Drop a .cap package here or choose a file — parsed entirely in your browser metadata.json · manifest.json · routes.json · storage.json · security.json

Live serving via service worker

A service-worker reactor installs your package, verifies every byte against security.json, and serves its routes right here under /playground/~serve/ — no server, no install.

or inspect a .cap above, then serve it live.

Everything stays on your device: the worker persists the package in the Cache API until you stop serving. Requires HTTPS or localhost.
