V8 Isolate Sandbox
Each function runs in its own V8 isolate with strict memory, CPU, and network limits. Full multi-tenant isolation out of the box.
Thunder Edge Runtime
A Rust-powered edge runtime built on the Deno stack. Deploy isolated JavaScript and TypeScript functions with per-request sandboxing, sub-millisecond cold starts, and built-in observability.
Dual-Listener Architecture
Separate admin (port 9000) and ingress (port 8080) listeners. Deploy functions via the admin API, invoke them through ingress routing.
Web Standards First
Write functions using standard fetch, Request, Response, crypto, WebSocket, and more. Full Web API compatibility.
Node.js Compatibility
Partial support for node:fs, node:crypto, node:buffer, node:stream, node:path, and 30+ other Node modules.
Built-in Observability
OpenTelemetry traces, metrics, and logs. Per-function metrics, saturation scoring, and a comprehensive metrics endpoint.
Fast Cold Starts
V8 snapshots and ESZIP bundling for fast startup. Isolate pooling and context-first scheduling for warm request routing.
