With Percy, you can add visual testing to virtually anything that runs in a browser.

We have first-class support for several web application frameworks, component libraries, end-to-end testing frameworks, and static sites. You can also build your own Percy integration.

Build your own SDK

---

Integrating Percy visual testing into a new framework is simple using Percy Agent.

The @percy/agent npm package is our core SDK that provides the foundation for all other SDKs. It takes care of all the heavy lifting of common tasks such as authentication, environment detection, and uploading snapshots to your Percy project. The agent also provides a JavaScript library that acts as the bridge between the agent and your application or tests running in any browser. Follow our documentation to build your own SDK .

If you're unsure about which SDK you should use or don't see your technology represented, feel free to reach out to support.
