Config integrity for distributed systems
Ferrule gives every config value a type, a signature, and a history — so what you shipped is exactly what you reviewed, in every environment, every time.
Every configuration value carries a type and a validator. Invalid config fails at commit, in CI, and at deploy — never in production at 3am. Coercions are explicit and logged, so a stringly-typed duration can't silently become the number 900.
See the exact key-level delta between any two environments before a single value lands. No blind promotes.
Every change is attributed, cryptographically signed, and versioned. Roll back to any prior state in one command.
The workflow
The Ferrule CLI is the whole loop. validate checks every key against its schema and blocks a broken apply. diff shows the exact delta between environments. Nothing lands that you didn’t see first.
