Cypress vs React Testing Library: open-source browser automation tools compared

Metrics as of , from the GitHub or GitLab API of each repository. Refreshed monthly.

Summary

Cypress: Browser testing tool for end-to-end, component, accessibility and API tests, run from a local app or CLI.

React Testing Library: Utilities for testing React components through react-dom, focused on how the software is used.

Both are listed under Browser automation. The table gives repository metrics from the GitHub API with their fetch date, then the documented facts used for every comparison in this category, each linked to the README or docs page it comes from. A cell reads "not documented" when the fact was not found in the project's documentation (4 of 14 fact cells here); that does not mean the feature is absent.
