The question asked, verbatim: best application performance monitoring for agencies

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - My default for most agencies.
2. Next.js mentioned
   Error tracking plus tracing and session replay in one tool, and the org/project structure maps cleanly onto "one project per client." SDKs for every stack you'll hit (Next.js, Laravel, Rails, React Native), 5-minute install, and the event-based pricing means a sleepy client site costs you almost not
3. New Relic mentioned
   New Relic - Best pick when you need real code-level APM, not just errors.
4. Better Stack mentioned
   Better Stack (or Checkly if your clients are JS-heavy) - For uptime, synthetic checks, and status pages.
5. Checkly mentioned
   Better Stack (or Checkly if your clients are JS-heavy) - For uptime, synthetic checks, and status pages.
6. Dotcom-Monitor mentioned
   Dotcom-Monitor - Worth a look specifically because it ships multi-tenant management and white-label reporting aimed at MSPs and agencies, starting around $20/month.
7. Datadog mentioned
   Datadog - Only when a client demands it or is already on it.
8. Grafana Cloud mentioned
   Grafana Cloud / SigNoz - The open-source route.
9. Grafana Cloud / SigNoz mentioned
   Grafana Cloud / SigNoz - The open-source route.
10. SigNoz mentioned
    Grafana Cloud / SigNoz - The open-source route.
11. OpenTelemetry mentioned
    Grafana Cloud's free tier is generous and SigNoz is OpenTelemetry-native and self-hostable, so you own the data and avoid per-seat costs across dozens of client projects.
12. ManageEngine Applications Manager mentioned
    ManageEngine Applications Manager - If your clients are on-prem, Windows, or traditional server stacks rather than modern cloud apps.
13. Sentry + Better Stack recommended
    The practical setup I'd recommend: Sentry + Better Stack as your standard stack on every client project, and add New Relic only for the clients with real backend complexity.

The answer, as recorded

For agencies the deciding factors are different from a single product team: you need per-client isolation, white-label or at least client-presentable reports, and pricing that scales per project without a per-host enterprise bill. Here's who I'd actually name, in order. **1. Sentry** - My default for most agencies. Error tracking plus tracing and session replay in one tool, and the org/project structure maps cleanly onto "one project per client." SDKs for every stack you'll hit (Next.js, Laravel, Rails, React Native), 5-minute install, and the event-based pricing means a sleepy client site costs you almost nothing. Session replay is also the single best thing to put in front of a non-technical client who says "the site is broken." **2. New Relic** - Best pick when you need real code-level APM, not just errors. The 100 GB/month free ingest tier plus per-user pricing is unusually agency-friendly: you pay for your handful of engineers, not for every client host you monitor. Full-stack coverage (APM, infra, logs, browser, synthetics) in one account, so you're not stitching four vendors together. ([cloudzero.com](https://www.cloudzero.com/blog/application-monitoring-tools/)) **3. Better Stack** (or **Checkly** if your clients are JS-heavy) - For uptime, synthetic checks, and status pages. Better Stack's status pages are genuinely good-looking and support custom domains, so each client gets `status.theirdomain.com`. Checkly is the better choice if you want monitoring-as-code - Playwright scripts for critical user journeys, versioned in the client's repo alongside the app. **4. Dotcom-Monitor** - Worth a look specifically because it ships multi-tenant management and white-label reporting aimed at MSPs and agencies, starting around $20/month. Less modern than the above, but it's one of the few that treats "I resell this to clients" as a first-class use case. ([dotcom-monitor.com](https://www.dotcom-monitor.com/blog/application-performance-monitoring-tools/)) **5. Datadog** - Only when a client demands it or is already on it. It's the strongest full-stack observability platform, but at ~$36/host/month plus separate line items for APM, logs, and RUM, the bill is unpredictable and it's hard to recover from a fixed-fee retainer. Bill it directly to the client's account, not yours. ([cloudzero.com](https://www.cloudzero.com/blog/application-monitoring-tools/)) **6. Grafana Cloud / SigNoz** - The open-source route. Grafana Cloud's free tier is generous and SigNoz is OpenTelemetry-native and self-hostable, so you own the data and avoid per-seat costs across dozens of client projects. Real caveat: you're now operating a monitoring stack, which is only worth it above roughly 20-30 client apps. ([signoz.io](https://signoz.io/blog/open-source-apm-tools/)) **7. ManageEngine Applications Manager** - If your clients are on-prem, Windows, or traditional server stacks rather than modern cloud apps. Perpetual-license option instead of a subscription, which some agencies prefer for pass-through billing. ([techjockey.com](https://www.techjockey.com/us/category/application-performance-management-software/windows)) The practical setup I'd recommend: **Sentry + Better Stack** as your standard stack on every client project, and add New Relic only for the clients with real backend complexity. That covers "is it down," "is it erroring," and "is it slow" for under $100/month total across a dozen clients, and both tools give you something you can screenshot into a monthly report.
