Hey Product Hunt 👋
I'm Krishna, and I built Otter Vault because I kept losing API keys. I'd generate one in a dashboard, paste it into a .env or a random note, and a week later have no idea where it went, or worse, find it sitting in plain text somewhere it shouldn't be.
Otter Vault fixes that:
• Detects API keys the moment they show up in your browser and offers to save them
• Encrypts everything on your device (AES-256-GCM, PBKDF2 key derivation)
• No servers, no accounts, no sync. Your secrets never leave your machine
• Chrome extension + a macOS menu bar app so your keys are one click away while you code
I went local-first on purpose: a vault for API keys shouldn't need you to trust yet another cloud.
I'd love your feedback. Which providers should detection support next, and what's missing from your key-management workflow? I'll be here all day answering questions.
this is the "find no idea where it went" problem exactly, good call building for it. one thing I'd want - once a key gets rotated or revoked on the provider side, does the vault know, or does it just keep holding dead keys forever next to the live ones? a vault full of stale secrets is almost worse than no vault.
