Who it’s for — and when to skip it

Data teams

Use it when you need transparent storage, processing, querying, or reporting behavior.

Skip if your required connectors or governance controls are not documented.

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.

Skip if nontechnical operators require a fully managed support model.

Strengths and trade-offs

Why teams consider it

for integration into existing web applications

flexible view

modular and configurable structure

Source code and EUPL-1.2 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 EUPL-1.2 license still needs review against your distribution and commercial model

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