source

public

The Dify Open Source License is Apache-2.0 with added conditions: a multi-tenant service restriction and branding requirements. That puts it outside OSI approval and charges for a class of use, so the public source does not make the product freely runnable. Cloud and enterprise tiers sit alongside it. Score corrected from 3 to 2 on 2026-07-30. The software ladder has rungs at 1, 2, 4 and 5 and none at 3, so 3/source_available was not a pair any rule could produce; the ladder scores "you can read it and not run it freely" at 2.
