Live API key validation — paste any key, CypherKeep auto-detects the provider and tests it in real time showing green/yellow/red status. No other credential manager does this. Combined with 100% local storage and BIP39 seed phrase validation, it's the only tool built specifically for developers and crypto users.
1Password and Bitwarden sync to the cloud — that's an attack surface. CypherKeep is 100% local, zero cloud, zero accounts, zero telemetry. It also understands what an API key actually is — provider detection, live testing, seed phrase validation. Generic password managers don't.
— Launched May 2026, early adopters only at this stage
I had API keys scattered across .env files, Notion, iCloud Notes, and Slack — one breach away from a cascade. Every existing manager either synced to the cloud or was too generic. So I built the tool I needed.
