Go Documentation

gddo is a maintained fork of the software that once powered godoc.org, and you can use it to browse documentation for Go packages.

A hosted instance is available at godocs.io.


First install the dependencies:

  • Go 1.16 or above

Then compile and install:

$ make
# make install

#Running with a database

gddo can optionally be used with a PostgreSQL database. Note that the following features require a database:

  • Package search
  • Import graphs

Install the runtime dependencies:

  • PostgreSQL 13
  • Graphviz (required for import graphs)

Initialize the PostgreSQL database:

psql -f schema.sql

Then run:

gddo \
	--db "postgres://localhost" \
	--http :8080 \
	--goproxy "https://proxy.golang.org"

#Running in standalone mode

gddo also supports standalone operation, which is best for viewing documentation locally. To use it, simply run:

gddo --http :8080

gddo will then begin serving documentation for modules in your local Go module cache. To add a module to the cache, run:

go mod download example.com/module@latest

See go help mod download for more information.

#Gemini support

gddo can also serve documentation over the Gemini protocol.

To serve documentation over Gemini only, run:

gddo --gemini :1965 --certs /var/lib/gemini/certs --hostname example.com

See the documentation for more information.
