Idenplane vs Auth0
Idenplane is an open-source, self-hosted alternative to Auth0. Where Auth0 is a managed SaaS you pay for per monthly active user, Idenplane runs on your own infrastructure under the AGPL-3.0 license — with no per-MAU pricing and no vendor lock-in — while implementing the same standards (OAuth 2.0 + PKCE, OpenID Connect, SAML 2.0) and shipping 10 official SDKs across web, mobile, and backend. You trade Auth0’s fully-managed convenience for full control of your data, predictable cost, and the ability to self-host in about 30 seconds.
Idenplane vs Auth0, compared
Auth0 is managed SaaS, so deployment rows are marked N/A rather than unsupported. Open a PR if anything is out of date.

- Auth0 and Clerk are managed SaaS — self-hosting is not an option, not an absence. Marked N/A in deployment rows.
- Memory and setup-time figures are from internal k6 load tests (50 virtual users, 60s, single realm, default config) — not idle measurements. Idenplane and Keycloak ran the identical workload; SuperTokens, Auth0, and Clerk figures are estimates, not benchmarked. Workload dictates real-world usage.

Why teams leave Auth0
Self-hosted and open source
Idenplane runs on your own infrastructure under the AGPL-3.0 license. Auth0 is a closed, fully-managed SaaS — you can’t run it yourself or read its source.
No per-MAU pricing
Auth0 bills by monthly active users, so costs scale with your growth. Idenplane has no per-user fee: you pay for the infrastructure you already run, and nothing else.
Own your identity data
With Idenplane, user credentials and profiles stay in your database and your region — useful for data-residency and compliance requirements. With Auth0, that data lives in Auth0’s cloud.
Same standards, 10 SDKs
Idenplane implements OAuth 2.0 + PKCE, OpenID Connect, and SAML 2.0, with 10 official SDKs across web, mobile, and backend — so migrating keeps your protocol integrations intact.
No vendor lock-in
Because Idenplane is standards-based and self-hosted, you’re never tied to one vendor’s roadmap, pricing changes, or deprecations.
Where Auth0 still leads
Auth0 is fully managed — no servers to run or patch — with a large integration marketplace, enterprise support and SLAs, and a broad set of compliance certifications. If “someone else runs it” is the priority, Auth0 is hard to beat.
