Beyond .env.example: envcheck Brings Declarative Schema Validation to Your Configs

While .env.example serves as a helpful template, it lacks the enforcement needed to prevent deployment crashes caused by invalid configuration values. envcheck solves this by offering a language-neutral, YAML-based schema validator that can be easily integrated into any CI pipeline via Docker. It allows teams to define strict types, ranges, and patterns for environment variables, ensuring system stability across polyglot architectures.
