What the engines say

Verbatim, from the answers themselves. We quote what an engine said and when it said it — never a paraphrase, and never our summary of it.

Check it yourself

Ask ChatGPT about this market →

You will not get our answer back, and you should not expect to. A single reply varies by the day, the account and the wording; the board is what several engines named across a fixed set of buying questions, recorded over time. What you can check is the part that matters — whether the products we say the engines name are the ones you are shown.

What decides a position

Four signals, chosen because a vendor cannot buy any of them directly. Each is a measurement of what the market does, not of what a company says.

AI answers

What AI engines answer when buyers ask what to use for a job.

Search results

Where the product stands in the search results buyers actually see for the category’s buying queries — including who owns the answer box.

Buyer demand

How many buyers search for the product by name.

Movement

Whether the product is gaining or losing ground against the others in its market, measured between dated captures rather than claimed.

A product is scored on the signals we could actually measure for it, and a signal we could not measure is left out rather than counted as zero. This is not a quality rating and not a recommendation. It measures how present and how well-regarded a product is across public surfaces — a different question from whether it is right for you.

Markets next to this one

Related because the rosters overlap, which is a fact about the products we track rather than a judgment about the markets. Each row says how much.

Observability platforms

7 of these 36 products also appear on that roster — Better Stack, Datadog and Dynatrace among them.

Incident management

4 of these 36 products also appear on that roster — Better Stack, Confluence and Ilert among them.

Product analytics

2 of these 36 products also appear on that roster — Fullstory and LogRocket.

In collection — it publishes when the signals behind it are sufficient.
