License stamps
A stamp tells you what the LICENSE file lets you do. We never call a source-available license "open source".
Open source: 25 projects
The whole repository is under an OSI-approved license.

The core is under an open license, but some directories (usually ee/ or enterprise/) are proprietary.
Activepieces, AFFiNE, Chatwoot, Dokploy, Formbricks, Mattermost, Metabase, PostHog, Rocket.Chat, Twenty, Windmill
Source-available: 4 projects
You can read the code, but the license is not OSI-approved (fair-code, Business Source, Functional Source or a custom license).
Under review: 0 projects
Licensing is mixed or unclear from the files we read; a human reading is still needed.
A stamp is our reading of the files on 2026-11-10, not legal advice. Licenses change: if you rely on one, read the file yourself.
