CYPHR

What is CYPHR?

CYPHR is a secure, lightweight API key storage built for developers. Store your keys in one place instead of scattering them across dotenv files, devices, notes, or password managers. Keys are encrypted with AES-256-GCM before storage, with fast global access via Cloudflare Workers and simple GitHub OAuth login. Fully open source and free to use, with up to 15 keys per user. No unnecessary enterprise complexity, just a simple way to store, manage, and access your API keys wherever you work.
