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

Brands named, in the order the engine gave

1. Sentry recommended
   Sentry - My default for most agencies.
2. Datadog recommended
   Datadog would charge you $31/host × every client.
3. Better Stack compared
   (Better Stack comparison (https://betterstack.com/community/comparisons/datadog-vs-sentry/))
4. Grafana Cloud recommended
   Grafana Cloud - Best value if you have someone who enjoys infrastructure.
5. New Relic recommended
   New Relic - The strongest pick when the client is paying for monitoring on their own account.
6. Only recommended
   Datadog - Only if you have one large enterprise client whose contract funds it, or if you're running the infrastructure too.
7. SigNoz recommended
   SigNoz or GlitchTip (self-hosted) - If margin matters more than your time.
8. GlitchTip recommended
   SigNoz or GlitchTip (self-hosted) - If margin matters more than your time.
9. Self Visa recommended
   Self-host once, onboard unlimited client projects at near-zero marginal cost, and you control data residency, which helps with clients who have GDPR or contractual constraints on where telemetry lands.
10. Checkly mentioned
    First, if the client apps are more than a couple, add a synthetic/uptime layer such as Better Stack, Checkly, or Pingdom - most agency incidents are "the site is down" or "checkout broke," and those get caught by synthetics well before a trace tells you anything.
11. Pingdom mentioned
    First, if the client apps are more than a couple, add a synthetic/uptime layer such as Better Stack, Checkly, or Pingdom - most agency incidents are "the site is down" or "checkout broke," and those get caught by synthetics well before a trace tells you anything.

The answer, as recorded

The tricky part of "for agencies" is that the usual APM rankings optimize for one big org running one big stack, whereas an agency needs many small isolated projects, per-client billing/handoff, and a bill that doesn't explode when client #12 arrives. Here's what I'd actually recommend, in order: **1. Sentry** - My default for most agencies. It's per-event, not per-host, so ten small client apps cost roughly what one does; Datadog would charge you $31/host × every client. Organizations → projects → teams maps cleanly onto client separation, and when a project ends you can hand the project over or archive it without unpicking a shared platform. Free tier for 5K errors, Team ~$26/mo, Business ~$80/mo. Its APM/tracing is now genuinely decent, not just error tracking. ([Better Stack comparison](https://betterstack.com/community/comparisons/datadog-vs-sentry/)) **2. Grafana Cloud** - Best value if you have someone who enjoys infrastructure. The free tier is unusually generous (10K metric series, 50 GB each of logs/traces/profiles, 3 seats), and it's OpenTelemetry-native, which matters for agencies: instrument the client's app with vendor-neutral OTel and you can hand the app off to the client's in-house team later without ripping out proprietary agents. That portability is worth a lot when your contract ends. ([performance.qa comparison](https://performance.qa/blog/apm-tools-compared/), [CubeAPM on Grafana pricing](https://cubeapm.com/blog/grafana-cloud-pricing-and-review/)) **3. New Relic** - The strongest pick when the client is paying for monitoring on their own account. 100 GB/month ingest free with 1 full-platform user is the most forgiving free tier out there, so small client apps often cost literally nothing. The catch is per-seat pricing on full users, which is bad for an agency wanting five engineers across twenty accounts - it works best as "one account per client, billed to the client." ([New Relic](https://newrelic.com/blog/apm/application-performance-monitoring-tools), [CompareStacks](https://comparestacks.com/developer-infrastructure/monitoring-observability/vs/grafana-cloud-vs-new-relic/)) **4. Better Stack** - Worth a look specifically because it bundles uptime monitoring, on-call, and **white-label status pages** - the thing agencies actually get asked for and that pure APM tools don't do. Costs a fraction of Sentry/Datadog at volume. Weaker on deep code-level tracing, so it's often a complement rather than a replacement. ([Better Stack vs Datadog](https://betterstack.com/community/comparisons/better-stack-vs-datadog/)) **5. Datadog** - Only if you have one large enterprise client whose contract funds it, or if you're running the infrastructure too. It is the most complete platform available and nobody gets fired for it, but per-host pricing plus multi-product SKUs is the worst possible shape for a many-small-clients business. Don't adopt it agency-wide. ([Coralogix](https://coralogix.com/guides/application-performance-monitoring-tools/), [PeerSpot rankings](https://www.peerspot.com/categories/application-performance-monitoring-apm-and-observability)) **6. SigNoz or GlitchTip (self-hosted)** - If margin matters more than your time. Self-host once, onboard unlimited client projects at near-zero marginal cost, and you control data residency, which helps with clients who have GDPR or contractual constraints on where telemetry lands. You're now running a monitoring service, so budget for that. ([Coralogix](https://coralogix.com/guides/application-performance-monitoring-tools/)) Two notes on the category. First, if the client apps are more than a couple, add a synthetic/uptime layer such as **Better Stack, Checkly, or Pingdom** - most agency incidents are "the site is down" or "checkout broke," and those get caught by synthetics well before a trace tells you anything. Second, if your agency is a *marketing* agency rather than a dev shop, this whole list is wrong for you and you want reporting tools like Whatagraph, NinjaCat, or PerkyDash instead - those are multi-client dashboards, not APM. ([PerkyDash](https://perkydash.com/guides/best-monitoring-tools-for-agencies), [Swydo](https://www.swydo.com/blog/best-white-label-reporting-tools/)) If you want one answer: **Sentry**, plus **Better Stack** for uptime and status pages.
