Logto
fifty thousand users free, then metered on tokens rather than people
the most generous published free tier here on a fully mpl-2.0 codebase, with a metering unit that quietly changes above it.
logto's free plan covers fifty thousand monthly active users, which lands this category's anchor exactly on the ceiling at $0. that is the most generous published free tier of anything ranked here, and unlike a trial it does not expire.
the whole codebase is mpl-2.0, confirmed against the licence text at github.com/logto-io/logto rather than the readme badge. mpl is file-level copyleft — modified mpl files stay mpl when distributed and binaries must make source available — which is a lighter obligation than agpl and a heavier one than mit. we found no open-core split.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

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.
