Better Auth
a plain mit framework with no metering at any scale
the only entry here where the code carries no commercial layer at all — and the only one you must operate entirely yourself.
better auth cannot be placed on this ranking's anchor, and that is the point rather than a gap. it is a typescript framework you install into your own application, licensed mit at github.com/better-auth/better-auth with no open-core split. there is no per-user metering at fifty thousand users or five million, because there is no meter. what you pay is your own infrastructure.
that is why it has become the standard destination for teams leaving clerk or auth0 once the bill starts mattering. the migration trades a monthly invoice for owning the sessions, the tables and the upgrade path.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
