## The answer, as recorded

Asked on 2026-09-06 through Claude (Anthropic) with web search (model claude-opus-5).

> Two different things get called "APM for agencies," and the answer splits on which one you mean: instrumenting client *applications* you build and maintain, versus watching a portfolio of client *sites* and reporting on it. I'll name both, application-side first.
> 
> ## For agencies that build and maintain client apps
> 
> **1. Sentry** - My default starting point. Errors plus tracing across 30+ platforms, so one tool covers the PHP site, the Rails app, and the React frontend. Unlimited users on paid plans matters when you have contractors rotating on and off client work. Plans start around $26/mo, billed by event volume. Caveat: its performance data is shallower than real APM - it'll tell you a view was slow, not that a specific query N+1'd. And event-based billing spikes exactly when a bad deploy happens. ([Better Stack comparison](https://betterstack.com/community/comparisons/datadog-vs-sentry/), [Scout](https://www.scoutapm.com/blog/best-apm-for-small-teams-2026))
> 
> **2. AppSignal** - The best fit if you want real APM without a DevOps practice. Combines APM, error tracking, and host metrics in one product, and - the part that matters for agencies - pricing is fixed tiers by request vol

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
