Feen

Secure API Key Sharing Platform

The open-source solution for managing, sharing, and monetizing your API keys securely.
Built for developers, teams, and enterprises.

Features • Quick Start • Documentation • Architecture • Contributing

Managing API keys across teams is challenging. Sharing them via Slack or email is insecure. Rotating keys is a pain. Tracking usage is nearly impossible.

Feen solves this by providing:

• Secure Storage: AES-256 encryption for all API keys
• Granular Sharing: Create access tokens with custom limits and restrictions
• Usage Tracking: Real-time analytics and audit logs
• Team Collaboration: Role-based access control for organizations
• API Marketplace: Buy and sell API access securely

• End-to-End Encryption: Your API keys are encrypted at rest using AES-256-GCM
• Zero-Knowledge Architecture: We never store or see your actual keys
• Shared Access Tokens: Create tokens with custom:
  • Rate limits (requests per minute)
  • Daily usage limits
  • IP whitelisting
  • Model restrictions
  • Expiration dates
• Real-Time Analytics: Track usage, costs, and performance
• Audit Logging: Complete history of all key access and modifications

• Node.js 20+
• PostgreSQL 14+
• Redis 7+
