Shaper од sexualrhinoceros

Passively captures API traffic as you browse and builds structured documentation from what it observes. Shaper groups requests into endpoints, infers JSON schemas from response bodies, decodes protobuf without a schema, tracks query parameters, and exports OpenAPI 3.x specs — all without touching the page.

Supports HTTP, GraphQL, gRPC-Web/Protobuf, and Server-Sent Events.



How it works: Start capture on a tab, browse normally, then open the dashboard to see every API endpoint the site uses — grouped by domain, with inferred request/response schemas, observed parameter values, copyable curl commands, and one-click export.

Features:
- Automatic endpoint grouping from raw traffic
- JSON schema inference that refines with every new sample
- Schema-less protobuf wire format decoding
- OpenAPI 3.x, HAR, .proto, and JSON export
- Per-tab or all-tabs capture with domain filtering
- Full dashboard with endpoint tree, header inspector, and sample viewer
- Alt+Shift+C keyboard shortcut
