Protobuf Wire compatibility Check — check proto changes before rollout
Flags wire-incompatible edits in .proto files - reused or unreserved field numbers, enum zero drift, JSON name collisions - before a gRPC rollout silently corrupts a field. Runs entirely in your browser — nothing is uploaded.
$29 once · one licence key per person or team seat · A contract backend engineer runs $60+/hour on the public marketplaces.
Free here: Reads the .proto file you have open and names every wire-breaking field, the line it is on, and the edit that keeps old readers working.. In the editor: Audits every .proto in the workspace at once and writes a PROTO-WIRE-AUDIT.md plus audit.json you can commit, attach to the pull request, or fail a build on. — that part asks for a licence key.
Same engine as the VS Code extension, byte for byte.
