September 2026 Edition. Every number here is derived from the raw labels under vendor table v2026-09-16.3, every buyer segment counted.

Standing

8 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. Knock was named 8 times in Mobile & push and 1 other category, where OneSignal led with 34%. The labels and the evidence are below, counted exactly.

Movement

This is the first edition on this tier, so no move can be computed for Knock yet. The next is due October 1, 2026. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“look into "notification infrastructure" platforms (such as Courier or Knock)” Gemini 3.5 Flash · Mobile & push · negative prompt · first choice

“Knock's channel set is particularly suited to B2B: SMS alongside email, push, in-app, Slack, and Microsoft Teams.” Claude Haiku 4.5 · Mobile & push · direct prompt · alternative

“API-first, developer-friendly, only charged for messages sent” Kimi K2 · In-app messaging · budget prompt · alternative

“Courier and Knock act as a unified notification API layer.” Gemini 3.5 Flash · Mobile & push · direct prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

No model argued against it.

What carried it into the answer

The sites and pages cited by the answers that named Knock. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 4 of the 27 answers that named Knock and are not a share of its labels.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Knock's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Knock, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at knock.app is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
