The flat-rate, zero-knowledge alternative
Doppler and Infisical are great — but they're priced per-seat / per-identity and store your secrets server-side by default. dotenvx is free — but it lives in your git repo with no vault or dashboard. EnvSync sits in the gap: a managed vault, zero-knowledge by default, one flat price.
| EnvSync | Doppler | Infisical | dotenvx | |
|---|---|---|---|---|
| Flat team pricing (no per-seat) | ✓ flat | per-seat | per-identity | free (OSS) |
| Server can never read your secrets | ✓ zero-knowledge | server-side | server-side (E2E opt-in) | ✓ (in repo) |
| Managed vault + dashboard + access logs | ✓ | ✓ | ✓ | ✗ |
| Secrets stay out of your git repo | ✓ | ✓ | ✓ | ✗ committed |
| Runtime injection (no .env on disk) | ✓ envsync run | ✓ | ✓ | ~ |
| Invite / offboard a developer instantly | ✓ one click | ✓ | ✓ | ✗ re-share keys |
| Setup | one command | moderate | self-host / moderate | simple |
Comparison reflects each tool's default/common configuration as of 2026. "Zero-knowledge" means encryption happens on the client and the server stores only ciphertext.
Coming from dotenvx?
Keep the zero-knowledge model, but get a real managed vault, a dashboard, access logs, and instant offboarding — without committing secrets to your repo or re-sharing keys.
Paying per seat?
If you run many client projects with churny contractors, per-seat pricing punishes you for growing. EnvSync is one flat rate for up to 15 developers.
Worried who can read them?
Doppler stores secrets server-side, and Infisical does by default — the provider can read them unless you opt into end-to-end encryption. With EnvSync, encryption always happens on your machine; we only ever store ciphertext.
