varlock

Why we included this project

Teams running Node or TypeScript services with a lot of environment variables can use Varlock to make a single .env.schema file the authoritative source of truth for configuration. Values are validated and coerced to the right types at load time, so a missing flag or wrong-typed setting fails before the app starts instead of surfacing mid-process. The AI-safety angle is what stands out: you can share that schema with coding agents and copilots so they learn the variable names, types, and validation rules without ever seeing the actual secrets. A scanner and git hooks catch secrets leaked into committed code, runtime integrations add log redaction and leak prevention, and if AI tools are working inside your repo, Varlock makes it safe to let them.
