Keyline vs Infisical
Infisical is the open-source secrets platform: broad, self-hostable, feature-rich. Keyline is the narrow tool for one job. Both are honest choices; here is the split.
The short version
Choose Infisical if you want a self-hosted platform, secret scanning, dynamic secrets, K8s operators, and SSO. It aims at the whole secrets lifecycle for growing orgs.
Choose Keyline if you are a 2 to 10 person team whose actual problem is "our .env lives in Slack". Two-minute setup, $19 flat, and a zero-knowledge design where our servers cannot read your secrets.
Side by side
| Keyline | Infisical | |
|---|---|---|
| Scope | Share .env files, control access, audit everything | Full secrets platform: scanning, rotation, dynamic secrets, PKI |
| Hosting | Hosted only, by design | Self-hostable or cloud |
| Encryption model | Zero-knowledge end to end: device keys, server holds ciphertext it cannot decrypt | Encrypted at rest; the platform can decrypt to power server-side features |
| Setup | Two minutes, four commands | Real platform setup: projects, machine identities, integrations |
| Pricing | $19 flat, whole team | Free tier, then per seat on cloud |
| Audit | Hash-chained, anchored to a public repo daily | Audit logs on paid tiers |
| Source | Public | Open source |
The honest framing
Infisical is what you graduate to when a platform team owns secrets as infrastructure. Keyline is what you use so that day arrives later and calmer: the .env you already have, encrypted properly, shared in one command, revocable in one command. If you are evaluating both, the question is not features, it is "who maintains this": with Keyline the answer is nobody on your team.
