What is Keeper secret store for Go?

Keeper's an embedded, crypto-hardened secret manager for Go apps, using bbolt DB with Argon2/XChaCha20 encryption and four bucket security levels from password-only to remote HSM.

Keeper vs HashiCorp Vault?

Keeper embeds locally (no network latency/outages), suits single-process Go; Vault scales distributed but adds sidecar overhead — pick Keeper for microservices, Vault for teams.

Is Keeper safe for production secrets?

Yes, with LevelRemoteHSM + mTLS to KMS; audit chain and per-bucket DEKs beat plaintext files. Audit it first.
