Secure API Key Management Platform for Teams

KeyVault is a free, secure API key management platform designed for development teams. It allows you to store, manage, and share API keys with enterprise-grade Fernet encryption (AES-128-CBC with HMAC-SHA256). When you sign up, an organization is created automatically. You can then create projects, add encrypted API keys, invite team members with role-based access control, and track all activity through comprehensive audit logs.

KeyVault has two plans. The Free plan includes 1 project with every feature — Fernet encryption, role-based access control, team collaboration, and audit logging — and requires no credit card. The Pro plan costs $10/month and unlocks unlimited projects for your organization. See the pricing page for details.

KeyVault uses enterprise-grade Fernet encryption (AES-128-CBC with HMAC-SHA256) with PBKDF2-derived keys. Additional security includes secure password hashing, rate limiting with account lockout after 5 failed attempts, CSRF protection, HttpOnly secure cookies, parameterized SQL queries, and multi-tenant data isolation between organizations.

Yes, KeyVault allows you to organize your API keys by projects and environments. You can create separate projects for each application or service, and within each project, separate your development, staging, and production API keys for clean environment management.

Yes, KeyVault is built for team collaboration. Invite team members via email with secure invitation tokens. Organization roles are boss (owner), manager, and employee, and project access is granted per project as read (masked values only), write, or admin. All access and modifications are tracked in the audit log.

KeyVault is a simpler, low-cost alternative designed for small-to-mid development teams. Unlike HashiCorp Vault (requires self-hosted infrastructure) or AWS Secrets Manager (charges $0.40 per secret per month), KeyVault is a hosted SaaS with a web UI, built-in team collaboration, a free plan, and a flat $10/month Pro plan. It is cloud-agnostic and works with any API keys.

Yes. Unlike Slack, email, or .env files, KeyVault encrypts all keys with Fernet encryption, provides role-based access control so only authorized team members see specific keys, and maintains a complete audit trail of who accessed what and when. Sharing keys via Slack or email leaves them in plaintext, searchable, and without access control.

No. Read-only project members receive a literal mask (••••••••••••) and a "masked: true" flag in the API response. Only the project owner and members with "write" or "admin" access ever see plaintext keys. The decision is enforced server-side, so the real secret never leaves the server for a read-only role.

No. If your email already has a KeyVault account, the invitation cannot be accepted unless the recipient is signed in with the matching email. Holding the invitation URL alone is insufficient. This closes the account-takeover-via-token-leak vector that affects many invitation-based platforms.

KeyVault runs on PostgreSQL hosted on Supabase, with connection pooling through Supavisor for serverless deployments on Vercel. Redis (Upstash) backs rate limiting, account lockout, and server-side session storage. The migration from MySQL/Aiven was completed in May 2026.

Getting started takes under 2 minutes: 1) Sign up for a free account at apisharing.vercel.app/signup, 2) Create your first project, 3) Add your API keys (they are encrypted immediately), 4) Invite your team members via email and assign roles. Your organization is created automatically when you sign up.
