Envlet and Infisical
Infisical is an open-source secrets platform you can self-host, with a wide surface from secret scanning to PKI. Envlet is a hosted service focused on the env vars a process starts with.
What Infisical does well
Infisical's server is open source and self-hostable, and its cloud paid plans are priced per user. It covers secrets management, certificate management, SSH, and more. If you must run the server yourself, it is the obvious choice.
Where Envlet differs
- Who counts as a seat
- Envlet bills humans only. Five coding agents are five identities and zero seats, on every plan including Free.
- Agents are first-class identities
- Every coding agent gets its own identity and token. Production starts withheld for it, and the audit log shows what it read, by name.
- Setup is one command, or one sentence
- envlet run -- in front of the command you already use, or the MCP server and the words move us to Envlet. Nothing to install on the host, nothing to operate.
- Hosting
- Envlet is hosted only, on Cloudflare Workers with a PlanetScale database. The SDKs and public mirrors are open source; the server is not. Values are encrypted per project under a root key held as a Worker secret.
Pick Envlet when
You want a hosted tool that your agents and CI use the same way your team does, with nothing to operate.
Pick Infisical when
You need to self-host, or you need PKI, SSH, and scanning in the same product.
