CypherKeep's answer:
Developers managing multiple API keys across projects, crypto users storing seed phrases and wallet credentials, security professionals who need air-gapped credential storage on macOS.
CypherKeep's answer:
Swift 5.9, SwiftUI, Apple CryptoKit (AES-256-GCM), Argon2id, SQLCipher, Apple Keychain Services, LocalAuthentication (Touch ID)
CypherKeep's answer:
Live API key validation โ 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.
CypherKeep's answer:
1Password and Bitwarden sync to the cloud โ that's an attack surface. CypherKeep is 100% local, zero cloud, zero accounts, zero telemetry. It also understands what an API key actually is โ provider detection, live testing, seed phrase validation. Generic password managers don't.

CypherKeep's answer:
I had API keys scattered across .env files, Notion, iCloud Notes, and Slack โ 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.
