The record

Purpose: Sabledocs is a static documentation generator for Protobuf and gRPC contracts.
Free and open source: The demo page describes Sabledocs as free and open source.
Generation: Sabledocs uses a command-line interface to generate static HTML documentation.
Multiple packages: It can build one documentation site for multiple packages.
Contract support: It can combine Protobuf and gRPC contracts in generated documentation.
Prerequisite: The package requires Python 3.11 or higher, and the build process uses a binary descriptor generated with protoc.
Search: Search can be enabled with a prebuilt Lunr index and is enabled by default.
Markdown: Markdown is supported in the main content page and in Protobuf comments.
Source links: Configuration can add source code links for Protobuf model members, with GitHub, Bitbucket, Bitbucket Data Center, and GitLab repository types supported.
Docker: A Docker image is available with both protoc and Sabledocs preinstalled.
Custom templates: Users can configure Jinja templates for primary content and add extra templates to generated output.
Comment parsing: An advanced option lets users preprocess Protobuf comments with a custom Python parser; the page cautions that this may make whitespace-sensitive formatting harder.
Input: It builds documentation from a binary Protobuf descriptor generated with protoc, and comments require the --include_source_info flag to be included.
Output: The generator creates a documentation site in sabledocs_output that can be opened through index.html.
Price from: Free
