Backend engineers
Consider it when the data model and APIs can remain portable across your infrastructure.
Skip if migration and backup procedures are unclear.
Analytics owners
Evaluate it when access to queries and source code is more valuable than a closed dashboard workflow.

Source code and NOASSERTION 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 NOASSERTION license still needs review against your distribution and commercial model
Support quality, migration effort, and production hardening vary by project
