Cloudflare Workers¶

Hayate runs as native Python inside Workerd. The normal entrypoint is a WorkerEntrypoint class, not an ASGI server embedded at the edge.

Choose the class entrypoint by default¶

The class path preserves:

• HTTP fetch;
• environment and D1 bindings;
• ctx.waitUntil;
• named RPC methods;
• class handlers such as scheduled.

The optional global handler is deliberately HTTP-only. It can reduce a small amount of dispatch overhead, but it cannot express the complete class contract.

Be honest about the runtime trade¶

The native Workerd benchmark records two different conclusions:

• Hayate's class adapter is close to its raw Python class ceiling.
• Hono's JavaScript Workers path remains materially better for startup, memory, CPU, and upload size.

Choose Python Workers when Python package reuse, one application contract, D1, MCP, or the Hayate ecosystem creates more value than JavaScript's runtime efficiency. Read the benchmark interpretation before presenting the result.
