Free Free Free app supports GitHub imports and manually created workspaces docs.protocall.dev · 4 Oct 2026

Purpose: ProtoCall describes its goal as simplifying each step of building an API with gRPC.
Web app: ProtoCall is a web app that requires no installation.
Local agent: ProtoCall Agent is a local webserver the web app needs to make outbound requests that browsers cannot make directly because of CORS restrictions.
Agent security: The agent applies its own CORS restrictions and uses additional authentication to prevent unauthorized non-browser processes from communicating with it.
Agent platforms: ProtoCall Agent is supported on Windows and macOS via a Docker container and on Linux as a binary executable.
Workspaces: A workspace is a collection of proto files resolved within one namespace using their packages and imports.
GitHub integration: Users can import GitHub repositories they own, collaborate on, or can access through organization membership; imports can track future changes automatically.
GitHub permissions: For accounts registered by email, GitHub import requests the repo and user OAuth scopes.
Manual import: Users can create a workspace manually and import proto files into it.
Workspace limit: ProtoCall currently supports single-repository workspaces, not multi-repository workspaces.
Audience: The maker's blog discusses ProtoCall in the context of engineering organizations managing proto files and gRPC service interfaces.
