Documentation and usage

Detailed usage instructions are available on the DapperDox website


We provide the lastest release builds for the most common operating systems and architectures, which you can download from releases, or you can build from source by cloning this repo.. See downloads for further information.

Build from source

First build DapperDox (this assumes that you have your golang environment configured correctly):

go get && go build

Running DapperDox

Start up DapperDox, pointing it to your OpenAPI 2.0 specification file:

./dapperdox -spec-dir=<location of OpenAPI 2.0 spec>

DapperDox looks for the file swagger.json at the -spec-dir location, and builds reference documentation for the OpenAPI specification it finds. For example, the obligatory petstore OpenAPI specification is provided in the examples/specifications/petstore directory, so passing parameter -spec-dir=examples/specifications/petstore will build the petstore documentation.

DapperDox will default to serving documentation from port 3123 on all interfaces, so you can point your web browser at or http://localhost:3123.

For an out-of-the-box example, execute the example run script:


This demonstrates many of the configuration options available. See configuration.


Many thanks to Ian Kent who spiked the Golang implementation of DapperDox as part of a bigger project. His commit history was lost when DapperDox was extracted into a stand-alone project, but its core retains his valuable work.

David Mort for painstaking testing, and bug fixing.
