Why Make zKkeynest?
We're building a secure, no-friction API key vault for developers and small teams. Starting with solo devs scraping together free-tier access to build products, we scale into team workflows where API keys are a core but messy part of the stack. There's no cheap clean solution for lightweight, encrypted key sharing today-and we're solving that.
The Problem
- Storing API keys unsafely in chat logs or emails
- Forgetting which API key belongs to which account
- Constantly logging in/out of different accounts to retrieve keys
- Lack of a cheap, secure way to share keys with team members
Our Solution
- Zero-knowledge encryption: All encryption/decryption happens client-side
- 99% Uptime: Data hosted on Google Cloud servers
- Social login: Google/GitHub authentication for frictionless access
- Unlock password protection: Additional security layer for viewing keys
- One-time sharing: Secure, encrypted links that expire after use
