Who it’s for — and when to skip it
Infrastructure teams
Use it when deployment control, auditability, and portability are primary requirements.
Skip if the team cannot own patching, monitoring, and incident response.
DevOps engineers
Consider it when automation and configuration can be reviewed and integrated into existing runbooks.
Skip if the project lacks a tested upgrade or rollback path.
Self-hosting teams
Evaluate it when running the service in your environment is a deliberate ownership decision.
Skip if a zero-operations SaaS experience is non-negotiable.

Source code and AGPL-3.0-or-later license are visible before adoption
Repository activity is available as a current maintenance signal
What to validate
Self-hosting transfers upgrades, backups, monitoring, and incident response to your team
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
