Serverless runtime on Zipper
Edge Functions
Edge Functions run your JavaScript in a secure sandbox on Zipper with up to 60 seconds wall-clock time and 10 seconds CPU. Use Web APIs (fetch, crypto, TextEncoder, structuredClone), import npm packages, handle WebSocket connections, stream responses, and run on a schedule with cron. Environment bindings give you access to KV, R2, D1, and Queues — the same API surface as Cloudflare Workers, plus Supabase-style database access through The Cellar. Supports fetch(), scheduled(), email(), and queue() handlers. Not a toy — production-grade serverless at the edge.
