Also offers paid editions — see the detail.
Self-hosted means you run the software on infrastructure you control. Some of it is free, some of it is paid — both belong here, and every entry states which one it is.
Every number on this page is counted from the database, not estimated.
Every entry shows the price model and the licence of its self-hosted edition.
Free and paid, clearly splitEvery entry states the price model of its self-hosted edition. A paid cloud plan never implies the self-hosted edition is paid.
Licence is not priceOpen source, source-available and proprietary are separate facts from what an edition costs, and both are shown.
Unknown stays unknownIf we could not read a price from a vendor source, the entry says so instead of showing a guess.
