Method and limits
Reports come from public Hacker News comments and public issues of vendors' open-source repositories; each was extracted into a structured item, and each links to its source. A report counts once per product, however many people agreed. Open-source and developer-facing products are over-represented because that is where public discussion happens; counts show how much is said, not which tool is better. Full method and sources.
