MockNest Serverless is an open-source, serverless API mocking solution that runs in your own AWS account, offering WireMock-compatible mock definitions and AI-assisted mock generation via Amazon Bedrock. It stands out by being the only serverless, customer-hosted option with support for response streaming and IAM authentication, making it interesting for teams needing stable, persistent test doubles for integration testing. The project demonstrates solid technical execution with Lambda SnapStart, AWS SigV4, and a structured self-correcting AI agent for mock generation.

Target audience: backend devs, devops, QA engineers
