THE EVIDENCE BEHIND THE ANSWER

Trust the evidence.
Understand the judgement.

No single score tells the whole story.
Each signal answers a different question.

01

Replacement fit

How well does this project replace a particular paid tool? Machine-derived assessments consider use cases, migration and deployment.

02

Project health

What do maintenance and release signals tell us? Health is shown separately from fit, with confidence and limits.

A LITTLE MORE CONTEXT

Good questions.

Is every project a direct replacement?+

No. Replacement fit is specific to the paid tool and its use cases. Review the assessment, deployment requirements and missing capabilities before choosing. Recommendations are a starting point for your evaluation.

Are all the projects open source?+

The globe uses projects with recognised open-source licences. The wider finder can also include approved source-available or open-core projects; these carry an explicit licence disclosure on their cards.

How fresh is the information?+

Counters, radar and recommendations refresh from The Source’s published data. Each panel shows its measurement date, with a labelled saved snapshot if the feed is unavailable.

Can I inspect or reuse the data?+

Yes. The published read layer is available on GitHub under CC BY 4.0, subject to the upstream notices. Follow the data notice for attribution and source terms.
