Catch Configuration Errors at Startup, Not in Stack Traces

Silent configuration errors escape validation in dotenv and surface later as cryptic failures buried in your application. By validating the entire environment against a typed schema before any code runs, you catch misconfigurations upfront with precise error messages, saving debugging time and preventing production incidents. With support for both Node and Python, zero dependencies, and direct CI integration, it addresses a critical gap in environment management practices for teams across any tech stack.
