Comparison
Keyway vs dotenvx
Two approaches to securing your .env files
dotenvx encrypts files you commit to git. Keyway removes them entirely with centralized, synced secrets.
Quick Summary
Keyway
Best for teams who want centralized secrets management with automatic sync and GitHub-based access control.
dotenvx
Best for developers who want to keep using .env files but need encryption, without a centralized service.

Key Differences
Understanding the fundamental differences helps you choose the right tool.
Architecture
Centralized secrets storage. Your secrets live on Keyway servers, encrypted at rest. Pull them when needed, never commit them.
Decentralized approach. Encrypted .env files are committed to your git repo. The private key stays separate (in CI, env vars, etc.).
AI Agent Integration
Built-in MCP server for Claude Code, Cursor, VS Code, and other AI tools. Use `keyway run` to inject secrets without exposing them to AI agents.
No MCP server. AI agents can read .env files on disk (even encrypted ones require the key to be available).
Key Management
No keys to manage. Keyway handles encryption/decryption. Access is controlled by your existing GitHub permissions.
You manage DOTENV_PRIVATE_KEY yourself. Store it in CI secrets, pass it to containers, share it with team members who need access.
Access Control
GitHub-native. If someone has repo access, they can pull secrets. Remove them from GitHub, access revoked instantly.
Key-based. Anyone with the private key can decrypt. When someone leaves, you should rotate the key and re-encrypt all files.
Which Should You Choose?
The best tool depends on your specific needs. Here's our honest take.
Choose Keyway if...
- You don't want to manage encryption keys
- You want access tied to GitHub permissions automatically
- You prefer secrets never touching your git history
- You need instant access revocation when someone leaves
- You use AI coding tools and want secrets protected from them
Choose dotenvx if...
- You prefer keeping secrets in your repo (encrypted)
- You're comfortable managing private keys
- You want to migrate gradually from plain .env files
- You want a fully decentralized approach with no server
- You need offline access to secrets
