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

Brands named, in the order the engine gave

1. APM mentioned
   The honest headline: there is no single "agency APM." What matters is per-client isolation, pricing that doesn't punish you for having 30 small clients instead of one big one, and client-facing output you can hand over.
2. Sentry mentioned
   Sentry - My default for most agencies.
3. Cheapest compared
   Projects map cleanly onto clients, errors + tracing + session replay in one, and when a client calls about a bug you get the stack trace and the replay instead of "it's broken on my phone." Cheapest serious option by a wide margin - SMB spend averages ~$5K/yr vs ~$100K for Datadog.
4. Datadog compared
   Projects map cleanly onto clients, errors + tracing + session replay in one, and when a client calls about a bug you get the stack trace and the replay instead of "it's broken on my phone." Cheapest serious option by a wide margin - SMB spend averages ~$5K/yr vs ~$100K for Datadog.
5. New Relic mentioned
   New Relic - The most agency-friendly commercial arrangement of the big three.
6. Grafana Cloud recommended
   Grafana Cloud - Best choice if you want one stack across all clients without lock-in.
7. OpenTelemetry mentioned
   OpenTelemetry-native, per-client stacks, a genuinely usable free tier, and because it's Grafana/Loki/Tempo/Mimir underneath you can self-host or hand the whole thing to a client at offboarding.
8. Better Stack mentioned
   Better Stack - Uptime + logs + incident on-call + status pages in one cheap product.
9. Uptime mentioned
   Better Stack - Uptime + logs + incident on-call + status pages in one cheap product.
10. Checkly mentioned
    Checkly - If your team already writes Playwright tests, this turns them into synthetic checks defined as code in git, per client, in CI.
11. AppSignal mentioned
    AppSignal (or Scout Monitoring) - For Rails/Laravel/Node shops.
12. WP Umbrella mentioned
    WP Umbrella or ManageWP - If your "applications" are mostly WordPress, skip real APM.
13. ManageWP mentioned
    WP Umbrella or ManageWP - If your "applications" are mostly WordPress, skip real APM.
14. WordPress mentioned
    WP Umbrella or ManageWP - If your "applications" are mostly WordPress, skip real APM.
15. Atatus mentioned
    Atatus - Worth a quote because it markets a multi-tenant agency offering with white-labeled per-client dashboards and volume pricing, at a fraction of Datadog.
16. Scout APM mentioned
    - Scout APM alternatives / pricing tiers (https://blog.appsignal.com/2025/02/13/the-top-5-scout-alternatives.html)

The answer, as recorded

Assuming you mean a digital/dev agency monitoring apps you build and maintain for clients (not a government agency - say the word and I'll redo it for that). The honest headline: there is no single "agency APM." What matters is per-client isolation, pricing that doesn't punish you for having 30 small clients instead of one big one, and client-facing output you can hand over. Here's what I'd actually name, in order: **1. Sentry** - My default for most agencies. Projects map cleanly onto clients, errors + tracing + session replay in one, and when a client calls about a bug you get the stack trace and the replay instead of "it's broken on my phone." Cheapest serious option by a wide margin - SMB spend averages ~$5K/yr vs ~$100K for Datadog. Weakness: it's app-level, not infrastructure. **2. New Relic** - The most agency-friendly *commercial arrangement* of the big three. Its partner program explicitly gives multi-tenant views across customer accounts and bills the partner monthly for all client accounts, so you can resell monitoring instead of eating it. Pricing is ingest-GB + per-user, so watch seat count. **3. Datadog** - Pick this when clients have real infrastructure (Kubernetes, multi-cloud) and budgets to match. Multi-org accounts give genuine client separation. Be disciplined: it's the most expensive by far and agency-style sprawl across many accounts is exactly how bills explode. **4. Grafana Cloud** - Best choice if you want *one* stack across all clients without lock-in. OpenTelemetry-native, per-client stacks, a genuinely usable free tier, and because it's Grafana/Loki/Tempo/Mimir underneath you can self-host or hand the whole thing to a client at offboarding. **5. Better Stack** - Uptime + logs + incident on-call + **status pages** in one cheap product. The status page is the underrated bit: it's a client-facing deliverable that makes your monitoring visible, which is how you justify billing for it. **6. Checkly** - If your team already writes Playwright tests, this turns them into synthetic checks defined as code in git, per client, in CI. The monitoring-as-code model fits agency repo-per-client workflows better than clicking checks into a UI. **7. AppSignal (or Scout Monitoring)** - For Rails/Laravel/Node shops. Flat, predictable pricing - Scout from ~$19/mo, AppSignal from ~$23/mo - and AppSignal includes unlimited users and apps, so you can give every client a login without seat costs. This is the pragmatic pick when "the app" is a mid-size client site, not a platform. **8. WP Umbrella or ManageWP** - If your "applications" are mostly WordPress, skip real APM. These do uptime, PHP error logging, updates and **white-label monthly client PDFs** - the thing clients actually read. ManageWP is free for unlimited sites with ~$1/site add-ons. **9. Atatus** - Worth a quote because it markets a multi-tenant agency offering with white-labeled per-client dashboards and volume pricing, at a fraction of Datadog. Caveat: I could not verify that agency pricing from an independent source, so treat it as a sales conversation, not a published rate card. Two things that matter more than the tool choice: instrument with **OpenTelemetry** so you can switch vendors without re-instrumenting 30 clients, and decide early whether accounts are client-owned (cleaner at offboarding, no liability for you holding their data) or agency-owned (better margin, but you're the single point of failure). One caveat on sourcing: the specific dollar figures above come from pricing aggregators, not vendor pages, and a few results that surfaced for this query were low-quality AI-generated SEO pages. Verify current pricing on the vendor's own site before committing.
