SuperTokens

unlimited self-hosted users, with the b2b features licensed separately

$0.02 per mau above 5,000, $100/mo minimum#teams-who-want-unmetered#do-not-need-multi-tenanc

an unlimited-user open-source core with the open-core line running straight through the features b2b products need.

the self-hosted core has no mau limit at all, so fifty thousand users costs nothing but infrastructure. the managed cloud is free to five thousand users then $0.02 each with a $100 monthly minimum, which puts fifty thousand users at $900 a month — mid-table, and an order of magnitude above clerk for the same count.

the licence needs reading carefully. the repository at github.com/supertokens/supertokens-core is apache 2.0 except the 'ee/' directory, which carries a proprietary supertokens enterprise licence. that licence permits use 'for development and testing purposes, without requiring a subscription', but production use requires agreeing to the subscription terms and holding 'a valid supertokens enterprise license for the correct number of user seats'. redistribution in production is forbidden and supertokens retains title to modifications you make.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

an unlimited-user open-source core with the open-core line running straight through the features b2b products need.

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.
