Skip if required editing, permissions, or migration features are missing.

Community operators

Strengths and trade-offs

Why teams consider it

Productivity

Collaboration

Communication

Source code and AGPL-3.0-or-later license are visible before adoption

Repository metrics are available for independent review

What to validate

A public repository does not automatically guarantee a documented self-hosting path

GitHub popularity is not a security, quality, or product-fit guarantee

The AGPL-3.0-or-later license still needs review against your distribution and commercial model

Support quality, migration effort, and production hardening vary by project
