Strengths and trade-offs

Why teams consider it

Form Builder

Json-logic

Mongolia DB

Source code and MIT 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 MIT license still needs review against your distribution and commercial model

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