Best Faultsense Alternatives
Faultsense is a lightweight, zero-dependency browser agent that evaluates end-to-end assertions against real user sessions in production. You write assertions as fs-* attributes on the UI elements they check, and Faultsense decides pass or fail in a real browser on the user's own device β 'the expect() without the page'. Assertions live next to the markup they check and run wherever your app runs, replacing CI-only test suites with in-field, real-user-session verification.
