What the data says

How many of these GTM tools have actually been tested?

The short answer

0. Every one of the 293 entries in this directory is RESEARCHED tier, meaning facts from public sources with URLs and no usage claims. Nobody here has run these tools. That number is printed on the front page rather than hidden, because it is what makes the other tier mean something.

The two tiers, and only two

There is no third tier, no star rating, no score and no featured field, because a field that exists is a field somebody eventually tries to buy.

What that means for every list on this site

Every capability list here answers one question: what does the vendor say this tool does, and can an agent reach it. It never answers which tool is better. There are no tool versus tool verdicts anywhere on this site and there will not be any until somebody has run both, because a comparison without a test is an opinion in a lab coat.

What would change the number

Andrew running a tool himself on a stated date, and publishing what happened including the parts that did not work. A vendor can offer access so a bench test becomes possible, that offer is recorded in the entry's notes, and the offer buys a test rather than a verdict. The verdict ships whatever it says.

Sources

Every number on this page is generated from directory.json at build time and carries the date it was baked: 2026-08-25. Nothing is typed by hand, nothing is rounded, and nothing is estimated. The underlying data is published in full. Where the honest answer is a zero, the zero is printed.
