Check out sphinxcontrib-openapi if you are interested in rendering OpenAPI spec within Sphinx page (i.e. inline).


The Sphinx extension that renders OpenAPI (fka Swagger) specs with love (❤️) using amazing ReDoc. Don’t believe it? Here’s the proof. Now stop frustrating and start moving your projects to OpenAPI and ReDoc with this small first step:

$ pip install sphinxcontrib-redoc


The whole configuration is done via Sphinx’s conf.py. All you have to do is to:

  • enable this extension

    extensions = [
       # ...
  • define OpenAPI specs to render

    redoc = [
            'name': 'Batcomputer API',
            'page': 'api',
            'spec': 'specs/batcomputer.yml',
            'embed': True,
            'name': 'Example API',
            'page': 'example/index',
            'spec': 'http://example.com/openapi.yml',
            'opts' {
                'lazy': False,
                'nowarnings': False,
                'nohostname': False,
                'required-props-first': True,
                'expand-responses': [200, 201],



    An API (human readable) name that will be used as page title.


    A page name to be used to form an output file. Passing api means: save rendered page as {outdir}/api.html. It also support complex paths such as foo/bar/api which will be resolved into something like {outdir}/foo/bar/api.html.


    A path to an OpenAPI spec to be rendered. Can be either an HTTP(s) link to external source, or filesystem path relative to conf directory.

    embed (default: False)

    If True, the spec will be embedded into the rendered HTML page. Useful for cases when a browsable API ready to be used without any web server is needed. The spec must be an UTF-8 encoded JSON on YAML OpenAPI spec; embedding an external spec is currently not supported.


    An optional dictionary with some of ReDoc settings that might be useful. Here they are

    lazy-rendering (default: False)

    If set, enables lazy rendering mode which is useful for APIs with big number of operations (e.g. > 50). In this mode ReDoc shows initial screen ASAP and then renders the rest operations asynchronously while showing progress bar on the top.

    suppress-warnings (default: False)

    If set, no warnings are rendered at the top of the document.

    hide-hostname (default: False)

    If set, both protocol ans hostname are not shown in the operational definition.

    required-props-first (default: False)

    If set, ReDoc shows required properties first in the same order as in required array. Please note, it may be slow.

    expand-responses (default: [])

    A list of response codes to be expanded by default.

    hide-loading (default: False)

    Do not show loading animation. Useful for small OpenAPI specs.

    native-scrollbars (default: False)

    Use native scrollbar for sidemenu instead of perfect-scroll. May dramatically improve performance on big OpenAPI specs.

    untrusted-spec (default: False)

    If set, the spec is considered untrusted and all HTML/markdown is sanitized to prevent XSS.
