Faultsense is a lightweight browser agent that turns E2E test assertions into runtime observability signals by validating feature correctness against real user sessions in production. Its innovative approach of using AI-instrumented DOM attributes to monitor assertions in live environments fills a gap between testing and production monitoring, making it valuable for teams wanting production quality assurance without separate instrumentation.

Target audience: frontend devs, QA engineers, devops
