MESH ONLINECODENAME: Final Countdown

REST vs Net

REST and webhooks are not the enemy, and they're not the model. They're the dirty edge — how Net meets systems that only speak HTTP.

The rule:

Use REST/webhooks when integrating legacy SaaS, browser-only apps, dashboards, or systems that only speak HTTP. Do not model Net internally as REST.

Where REST fits in the hierarchy

There is a deliberate ordering of integration surfaces, from first-class to edge:

  1. Native Net — SDK / daemon / nRPC. First-class. Typed capabilities, discovery, events, streams, artifacts, recovery. This is the substrate.
  2. The MCP bridge. The ecosystem wedge — the fastest way to bring existing tool supply onto the mesh (MCP vs Net).
  3. REST / webhooks. The edge. For legacy SaaS, browser-only apps, dashboards, and anything that will only ever speak HTTP.

REST belongs at the boundary, translating between an HTTP-only system and the mesh. It does not belong in the middle: Net's internals are events, capabilities, and causal state — not resources and verbs. Modeling the mesh as a REST API is the mistake that makes people mistake Net for an API gateway. It isn't one.

Why not model Net as REST

  • REST is request/response. The mesh is evented — work has stages, streams, and failures that a resource-and-verb model flattens into a status code (see Submitted Is Not Completed).
  • REST assumes a fixed endpoint. The mesh discovers capabilities by what they do, not by URL. There's no canonical host to point at.
  • REST terminates trust at every hop (load balancers, proxies, gateways see plaintext). The mesh is encrypted end-to-end between the actual endpoints.

Practical shape

When you must integrate an HTTP-only system, put a thin adapter at the edge that speaks REST/webhooks on one side and announces a capability (or publishes/consumes events) on the other. The HTTP system stays in its world; the mesh stays in its. The adapter is a translator, not the architecture.

This page is a positioning note, not an integration guide — there is no first-class REST adapter shipped today (unlike the MCP, Redis, and JetStream adapters). If you're building an edge adapter, model it as a capability announcer, and keep the HTTP surface at the boundary.
