Schema Validation

Avoid production typos. Write JSON Schema for your configuration, and we'll have your back.

Strong Typing

Use it with TypeScript without separate validation. Types are generated based on JSON Schema constraints.

Powerful and Robust

Flexible parsing extensions and file loading strategies. File merging, environment-specific values and more.

First Class Encryption

Manage your secrets in version control, backed by OpenPGP. Or keep secrets out of committed files with schema validation.

Use Your Tools

Don't be constrained by your tools. Export environment variables for usage in any application.

Multi-Format

Write YAML, TOML, JSON, JSON5 - whatever makes most sense for you.
