MockNest Serverless is a serverless mock runtime for AWS that enables realistic integration testing without relying on live external services. It runs natively on AWS Lambda and persists mock definitions in Amazon S3, with asynchronous webhooks/callbacks and AI-powered mock generation using Amazon Bedrock.
WireMock-compatible mocks on Lambda when local mock servers won't persist.

Right-click network requests to swap responses from inside DevTools — no proxy, server, or terminal required. The standout is the mix of BYOK/local-LLM AI generation, GitHub sync, and scenario chaining so you can build reproducible stateful flows, but expect the usual tradeoffs around managed-AI privacy and browser-extension limitations.
Puppeteer wrapper for Lambda when Playwright Cloud and Screenshot.rocks exist.
Zero-config OpenAPI mocking with behavioral inference, unlike Prism's manual setup.
Wire-protocol parsing means zero Docker overhead for Kafka integration tests.
Satirical deck-builder that turns 'CEOs slain' into a browser persistence mechanic.
CI-enforced regex equivalence checks across TypeScript and Python runtimes is a clever safety pattern.
