# flask-openapi3-rapidoc — Provide RapiDoc UI for flask-openapi3.

License: permissive · Maintenance: active · Downloads: 75.9K/mo

## What it is and what it does

flask-openapi3-rapidoc is a plugin that integrates RapiDoc, an interactive OpenAPI documentation UI, into Flask applications built with flask-openapi3. It provides an alternative to other OpenAPI UI options (Swagger, Redoc, etc.) for visualizing and testing API endpoints.

The package is a thin wrapper that makes RapiDoc available as an optional UI template for flask-openapi3 projects. After installation, developers can use RapiDoc to explore their API schema, view endpoint details, and send test requests directly from the browser. It requires only flask-openapi3 as a runtime dependency and installs as a pure Python wheel with minimal friction.

Use it for:

- Display interactive API documentation alongside your Flask API without writing custom UI code.
- Allow API consumers to test endpoints and view request/response schemas through RapiDoc's interface.
- Provide an alternative OpenAPI UI when Swagger or Redoc does not meet your design or feature preferences.
- Bundle multiple UI options (Swagger, Redoc, RapiDoc) and let users choose their preferred documentation viewer.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Adds RapiDoc as an interactive OpenAPI UI option to flask-openapi3 applications, enabling developers to browse and test API endpoints through a web interface.

Yes, if you are already using flask-openapi3 and want RapiDoc as your OpenAPI UI. The package is actively maintained, has no known vulnerabilities, installs with low friction, and carries a permissive MIT license. Install only if you specifically prefer RapiDoc's interface; flask-openapi3 supports multiple UI plugins, so choose based on your documentation needs.

## Install

pip install flask-openapi3-rapidoc
uv add flask-openapi3-rapidoc
poetry add flask-openapi3-rapidoc

## Installing flask-openapi3-rapidoc

Before you install: Low friction installation as a pure Python wheel. Active maintenance with recent commits and stable production status. Single lightweight runtime dependency on flask-openapi3.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and commercial projects without attribution requirements.

Quickstart:

pip install flask-openapi3-rapidoc

from flask import Flask
from flask_openapi3 import OpenAPI

app = OpenAPI(__name__)
# RapiDoc UI automatically available at /openapi/swagger (or configured endpoint)

Requires flask-openapi3 to be installed and configured; RapiDoc UI is optional and must be explicitly enabled in flask-openapi3 configuration.

Verify before relying:

- Whether RapiDoc UI is automatically enabled after installation or requires explicit configuration in flask-openapi3.
- The specific URL endpoint where RapiDoc UI is served by default.
- Whether this package works with all versions of flask-openapi3 or has version constraints beyond what pip resolves.
