What this is

sourc.dev tracks, measures, and compares language models, AI tools, APIs, and developer infrastructure — over time, based entirely on verified data. It is not a review site. It is not a ranking based on opinion. Every number has a source URL, a verification date, and a confidence level. Nothing is published without all three.

How data is collected

Primary sources only

Every data point links to the vendor's own documentation, pricing page, or API. No scraping aggregators. No secondhand data.

Append-only archive

Nothing is deleted. Every observation is timestamped and preserved. The history is the product.

Automated monitoring

Pricing pages are checked daily. Changes are detected by hash comparison and verified before publishing.

No opinions

No star ratings. No paid rankings. No editorial recommendations. The data speaks for itself.
