What each one is

HashiCorp Vault. HashiCorp Vault is a security product for managing secrets and protecting sensitive data.

Infisical. Infisical is an all-in-one open source security platform for secrets management, certificate management, privileged access management, secrets scanning, and key management.

Where Infisical is ahead

Infisical passes clear canonical domain, clear product positioning and llms.txt published, and HashiCorp Vault does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: authentication documented, pricing understandable and limits / constraints documented. HashiCorp Vault misses those.

And on adopt, self-service signup, no mandatory sales call, agent-compatible signup flow, free trial or free allowance, fast time to first request and official python sdk. HashiCorp Vault misses those.

What neither does

Both fail llms-full.txt / full agent docs, structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
