fastapi-offline
FastAPI without reliance on CDNs for docs
Decision gist · record as of 2026-08-14
Yes. If you need FastAPI documentation to work without CDN access, this package solves that problem with minimal friction—a single dependency, permissive licensing, active maintenance, and a straightforward API. Install it when disconnected networks, air-gapped deployments, or strict network policies make CDN-dependent docs impractical.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later.
- Low friction: single runtime dependency (fastapi), pure Python wheel distribution.
- Active maintenance with a recent release (56 days ago) and an archived repository status of false.

What it is and what it does
FastAPI-offline is a drop-in replacement for FastAPI that bundles Swagger UI and Redoc documentation assets locally instead of fetching them from external CDNs. This solves the problem of API documentation becoming inaccessible in disconnected networks, air-gapped environments, or situations where external CDN access is restricted or unreliable.
The package automates what the official FastAPI documentation describes as a manual process: it includes the necessary JavaScript and CSS files for both Swagger and Redoc, serves them locally, and configures a FastAPI instance to use them. You instantiate FastAPIOffline instead of FastAPI, optionally customize the static asset path or favicon, and everything else works as normal—all FastAPI options pass through unchanged.
Use it for
- Running FastAPI services in air-gapped or disconnected networks where external CDN access is unavailable or forbidden.
- Deploying API documentation in environments with strict network policies or firewall rules that block CDN domains.
- Ensuring API docs remain accessible even if external CDN services experience outages or performance degradation.
- Building self-contained Docker images or offline-first deployments where all dependencies must be bundled locally.
- Customizing documentation UI appearance by serving your own favicon alongside the standard Swagger and Redoc interfaces.
