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

Brands named, in the order the engine gave

1. APM mentioned
   "APM for agencies" splits into two different problems, and the answer depends on which you have:
2. Sentry mentioned
   Sentry - my default for agencies, and what I'd pick if you only buy one thing.
3. New Relic mentioned
   New Relic - the best fit if you want genuine full-stack APM across many small clients.
4. Grafana Cloud mentioned
   Grafana Cloud - pick this if you're cost-sensitive at volume or want to resell monitoring as a line item.
5. Cloud mentioned
   Grafana Cloud - pick this if you're cost-sensitive at volume or want to resell monitoring as a line item.
6. Datadog compared
   The free tier is genuinely usable for small clients, and at ~100 hosts the gap is reportedly dramatic - a few hundred a month versus Datadog's thousands.
7. OpenTelemetry mentioned
   It's also OpenTelemetry-native, so you're not locked in and can hand a client their own stack on exit.
8. Better Stack mentioned
   Better Stack - the white-label layer, and the thing that actually answers the retainer-justification problem.
9. Checkly mentioned
   Checkly - if you do frontend/e-commerce work.
10. Oh Dear mentioned
    Oh Dear - narrower, but if you're a PHP/Laravel shop its uptime, cert, broken-link and scheduled-task monitoring plus clean status pages are a near-perfect retainer fit.
11. ManageWP mentioned
    ManageWP or MainWP - only relevant if you're a WordPress agency, in which case they beat everything above for your actual job: updates, backups, and white-label client reports across sites.
12. MainWP mentioned
    ManageWP or MainWP - only relevant if you're a WordPress agency, in which case they beat everything above for your actual job: updates, backups, and white-label client reports across sites.
13. WordPress mentioned
    ManageWP or MainWP - only relevant if you're a WordPress agency, in which case they beat everything above for your actual job: updates, backups, and white-label client reports across sites.
14. Dynatrace mentioned
    Dynatrace and AppDynamics round out most "best APM" lists and are strong products, but I'd skip both for agency work - enterprise sales cycles, ~$58/host, and AI-driven root-cause analysis you don't need across small codebases.
15. Sentry + Better Stack mentioned
    Sentry + Better Stack.
16. Rollbar mentioned
    - Best APM Tools 2026 - Rollbar (https://rollbar.com/blog/best-apm-tools)
17. Atatus compared
    - Atatus vs Datadog vs New Relic pricing (https://www.atatus.com/guides/atatus-vs-datadog-vs-new-relic-pricing/)
18. Dotcom-Monitor mentioned
    - Top APM tools 2026 - Dotcom-Monitor (https://www.dotcom-monitor.com/blog/application-performance-monitoring-tools/)

The answer, as recorded

## The honest framing first "APM for agencies" splits into two different problems, and the answer depends on which you have: - **You build and run apps for clients** (custom code, deploys, on-call) → you need real APM: traces, errors, releases. - **You maintain client sites and need to show clients you're earning the retainer** → you need uptime + synthetics + white-label reports, not APM. Most agency tooling pain comes from buying the wrong one of those. Also worth knowing up front: **none of the serious APM vendors white-label.** If client-branded PDFs are the requirement, that's a separate, cheaper tool layered on top. ## What I'd actually recommend, in order **1. Sentry** - my default for agencies, and what I'd pick if you only buy one thing. The model fits agency shape better than anything else: one org, unlimited projects, so each client is a project with its own alerts and access. You pay for events, not hosts or seats - so twelve small client apps cost roughly nothing instead of twelve host licenses. Errors, tracing, and session replay in one place, and session replay in particular is gold for agency work because it ends "it's broken on my end" arguments with clients. Weak spot: it's app-level, not infrastructure. **2. New Relic** - the best fit if you want genuine full-stack APM across many small clients. Ingest-metered ($0.35/GB after 100GB free monthly) rather than per-host, which is the pricing axis that matters when you have thirty low-traffic client apps instead of one big system - per-host products punish you for exactly that shape. The catch is the $49/user Standard tier capped at 5 users; a 20-person agency hits Pro at $349/user and the math turns bad fast. Great for small agencies, poor for large ones. ([pricing comparison](https://www.atatus.com/guides/atatus-vs-datadog-vs-new-relic-pricing/)) **3. Grafana Cloud** - pick this if you're cost-sensitive at volume or want to resell monitoring as a line item. The free tier is genuinely usable for small clients, and at ~100 hosts the gap is reportedly dramatic - a few hundred a month versus Datadog's thousands. It's also OpenTelemetry-native, so you're not locked in and can hand a client their own stack on exit. Cost is real setup labour and clumsy multi-tenancy - separate stacks per client gets awkward. ([pricing at scale](https://monitoringcost.com/apm-pricing-comparison)) **4. Datadog** - the one you use *when the client is paying for it directly.* Best breadth in the market, and if you're working with an enterprise client they likely already have it, so you plug in rather than sell. Don't absorb it into your own overhead: at ~$31-35/host/month plus indexed spans and $0.10/GB logs, per-host pricing is actively hostile to a portfolio of small sites. Fine as a pass-through cost, bad as an agency P&L item. ([pricing](https://docs.datadoghq.com/agent/configuration/dual-shipping/), [comparison](https://monitoringcost.com/apm-pricing-comparison)) **5. Better Stack** - the white-label layer, and the thing that actually answers the retainer-justification problem. Uptime, incident management, and status pages on client custom domains with their branding. Cheap. Pair it with Sentry and you've covered ~90% of agency needs for well under what one Datadog tier costs. **6. Checkly** - if you do frontend/e-commerce work. Monitoring-as-code via Playwright, so synthetic checks live in the client's repo and version with the project. "Is checkout still working on all eleven client stores" is a question this answers well and APM doesn't. **7. Oh Dear** - narrower, but if you're a PHP/Laravel shop its uptime, cert, broken-link and scheduled-task monitoring plus clean status pages are a near-perfect retainer fit. **8. ManageWP or MainWP** - only relevant if you're a WordPress agency, in which case they beat everything above for your actual job: updates, backups, and white-label client reports across sites. MainWP is self-hosted and open-source if you'd rather not pay per site. Neither is APM; don't expect traces. ([overview](https://dev.to/johnsmith244303/managing-multiple-wordpress-sites-tools-and-strategies-for-agencies-2ccg)) **Dynatrace and AppDynamics** round out most "best APM" lists and are strong products, but I'd skip both for agency work - enterprise sales cycles, ~$58/host, and AI-driven root-cause analysis you don't need across small codebases. Use them only when a client mandates it. ([list context](https://rollbar.com/blog/best-apm-tools)) ## If you want one answer **Sentry + Better Stack.** Sentry for the engineering reality of debugging client apps, Better Stack for the commercial reality of proving uptime to clients in their own branding. Add New Relic if you need infrastructure-level visibility; add Datadog only on the client's invoice. One caveat on sourcing: several "best monitoring tools for agencies" pages that surfaced in my searches are thin affiliate content promoting tools I can't vouch for, so I've left those products out and stuck to ones with a real track record.
