CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Developers managing secrets across multiple cloud providers during local development should use Teller for its provider-agnostic approach; it pulls from AWS Secrets Manager, HashiCorp Vault, 1Password, and others without forcing a single vault standard. The 3,181 GitHub stars and free pricing mean adoption friction is genuinely low for teams testing secret rotation workflows before committing to a paid platform. Skip this if you need runtime secret injection in production containers or centralized audit logging; Teller is built for the laptop-to-staging workflow, not the control plane.
