Stunt Double vs TestSprite

TestSprite is an AI testing agent for developers. It explores a running web app, generates frontend and backend end-to-end tests, runs them in a cloud sandbox, repairs failing ones and reports the results. It works from the IDE through its MCP server or from CI, and its GitHub App tests each pull request’s preview deployment. The output is test code you keep.
