why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the security job, so this one still earns its $16/mo.
- A named launch, not a vibe named, unlinked
- Auth0 pricing pressure from Clerk and free open-source libraries built into frameworks. Anthropic, November 4, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 3 of 3 listed replacements have a usable free tier: Keycloak, Ory and Clerk.
- What the call is worth $192/yr
- $16/mo at the entry paid tier — $192 a year per seat.

The backstory
Logto is the open-source answer to Auth0's pricing, offering the same core, social login, multi-factor, organisations and enterprise SSO, with source you can host yourself when the invoice gets uncomfortable or the data cannot leave your jurisdiction. The category is brutal, with free libraries below and polished commercial products above. Being genuinely self-hostable with a modern developer experience is a narrow but real position that neither end of the market covers.
