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.

When each fits
Written from each project's documented scope, not from preference. Neither tool is ranked.
Cypress
Fits projects that test applications running in a browser; its docs describe end-to-end testing, component testing and accessibility testing in one locally installed app. source: Docs: Why Cypress?
React Testing Library
Fits projects that test React components; its docs describe APIs for working with React components, added to DOM Testing Library. source: Docs: React Testing Library Introduction
