cherrypy-cors
CORS handling as a cherrypy tool.
Decision gist · record as of 2026-08-14
Yes. This is a lightweight, actively maintained tool for a common need in web development. If you're building a CherryPy application that needs to serve cross-origin requests, it's the natural choice. The permissive MIT license and low dependency count make it safe to add. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires CherryPy to be installed and configured; Python 3.8 or later.
- Low friction installation with only two runtime dependencies (cherrypy and httpagentparser).
- The package is actively maintained with a recent release in August 2023 and an active repository.

What it is and what it does
cherrypy-cors is a CherryPy tool that handles Cross-Origin Resource Sharing (CORS) headers for web applications. It lets you enable CORS either globally across your entire application or selectively for specific routes and resources, managing the HTTP headers that browsers use to determine whether cross-origin requests are allowed.
The package integrates directly into CherryPy's configuration system, so you enable it by adding tool settings to your route or application config rather than writing custom middleware. It has been stable since its initial release and requires only CherryPy and httpagentparser as runtime dependencies, making it lightweight to add to existing CherryPy projects.
Use it for
- Enable a CherryPy-based API to accept requests from web frontends hosted on different domains.
- Selectively expose static resources (CSS, JavaScript, images) to cross-origin requests while protecting other endpoints.
- Configure CORS headers for specific application routes without modifying core request handling logic.
- Allow browser-based clients to make XMLHttpRequest or Fetch API calls to your CherryPy backend.
