Manifestack

Manifestack is an open-source tool that audits and manages your development stack inside your coding agent. It inspects your entire product's frontend, backend, infrastructure, and third-party APIs to ensure your services fit your requirements, budget, and growth forecast. It helps developers and small teams choose and maintain hosting, databases, authentication, email, and other services, tracking costs, limits, and overlaps without changing code automatically. It runs locally with no account or API keys, writing only a manifest file summarizing your stack.
