Infisical

Infisical is an open-source security platform that helps engineering teams manage secrets, certificates, and machine identities in one place. Born out of Y Combinator's W23 batch, it replaces scattered .env files and hardcoded API keys with a unified, MIT-licensed stack covering secrets management, dynamic secrets, rotation, secret scanning, PKI, KMS, SSH, and privileged access. Used by companies like Hugging Face, LG, and Lucid, it secures billions of secrets and is backed by Elad Gil, Google's Gradient Ventures, and Y Combinator.
