spaCy Universe

The spaCy Universe collects the many great resources developed with or for spaCy. It includes standalone packages, plugins, extensions, educational materials, operational utilities and bindings for other languages.

If you have a project that you want the spaCy community to make use of, you can suggest it by submitting a pull request to this repository. The Universe database is open-source and collected in a simple JSON file.

Looking for inspiration for your own spaCy plugin or extension? Check out the project idea label on the issue tracker.



βœ… Libraries and packages should be open-source (with a user-friendly license) and at least somewhat documented (e.g. a simple README with usage instructions).

βœ… We're happy to include work in progress and prereleases, but we'd like to keep the emphasis on projects that should be useful to the community right away.

βœ… Demos and visualizers should be available via a public URL.

Educational Materials

βœ… Books should be available for purchase or download (not just pre-order). Ebooks and self-published books are fine, too, if they include enough substantial content.

βœ… The "url" of book entries should either point to the publisher's website or a reseller of your choice (ideally one that ships worldwide or as close as possible).

βœ… If an online course is only available behind a paywall, it should at least have a free excerpt or chapter available, so users know what to expect.

JSON format

To add a project, fork this repository, edit the universe.json and add an object of the following format to the list of "resources". Before you submit your pull request, make sure to use a linter to verify that your markup is correct. We'll also be adding linting for the universe.json to our automated GitHub checks soon.
