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

Brands named, in the order the engine gave

1. APM mentioned
   One framing note first, since it drives the whole answer: for an agency the hard part isn't the APM's feature list, it's per-client isolation, billing you can hand off, and cost that survives having 30 small apps instead of 3 big ones.
2. Sentry mentioned
   Sentry - my default pick for most dev/digital agencies.
3. Grafana mentioned
   Grafana Cloud - best economics if you're willing to own the setup.
4. Grafana Cloud mentioned
   Grafana Cloud - best economics if you're willing to own the setup.
5. Cloud mentioned
   Grafana Cloud - best economics if you're willing to own the setup.
6. OpenTelemetry mentioned
   It's OpenTelemetry-native, which means your instrumentation is portable - you're not re-instrumenting a client's app if they later insist on Datadog.
7. Datadog mentioned
   It's OpenTelemetry-native, which means your instrumentation is portable - you're not re-instrumenting a client's app if they later insist on Datadog.
8. New Relic mentioned
   New Relic - the sleeper pick for agencies specifically.
9. Better Stack mentioned
   Better Stack - the client-facing layer on top of whichever APM you choose.
10. Checkly mentioned
    Checkly - if client sites have critical flows (checkout, signup, booking).
11. ManageEngine Applications Manager mentioned
    ManageEngine Applications Manager or Site24x7 - if you're closer to an MSP than a dev shop.
12. Site24x7 mentioned
    ManageEngine Applications Manager or Site24x7 - if you're closer to an MSP than a dev shop.
13. Ruby mentioned
    These are the ones built for multi-tenant from the ground up: code-level visibility across Java/.NET/PHP/Node/Python/Ruby, per-tenant dashboards, white-label, and a self-hostable option if a client has data-residency rules.

The answer, as recorded

Searched; here's what I'd actually recommend. One framing note first, since it drives the whole answer: for an agency the hard part isn't the APM's feature list, it's **per-client isolation, billing you can hand off, and cost that survives having 30 small apps instead of 3 big ones.** That's what reorders the usual rankings. **1. Sentry - my default pick for most dev/digital agencies.** Errors, tracing, and session replay in one tool, and critically it's priced on event volume, not seats, so your whole team (and the client's devs) get access for free. Billing is bound to the *organization*, so the clean agency pattern is one Sentry org per client - then when the engagement ends you invite the client as a billing member or hand the org over entirely, with no data migration. Free developer tier covers small projects; Team includes 50k errors, overages from ~$0.00029/error. ([sentry.io/pricing](https://sentry.io/pricing/), [docs.sentry.io/pricing](https://docs.sentry.io/pricing/)) **2. Grafana Cloud - best economics if you're willing to own the setup.** The free tier is genuinely usable (10k metric series, 50GB logs, 50GB traces, 50GB profiles, 100k synthetic checks, 50k frontend sessions, 14-day retention, 3 users), so small clients can each get their own stack at $0. Pro is $19/mo platform fee + $0.40/GB traces, $6.50/1k series. It's OpenTelemetry-native, which means your instrumentation is portable - you're not re-instrumenting a client's app if they later insist on Datadog. Reported real-world gap is large: ~$5.5k/mo on Datadog vs ~$300-800/mo on Grafana Cloud Pro at 100 hosts. ([grafana.com/pricing](https://grafana.com/pricing/), [grafana.com free tier](https://grafana.com/products/cloud/free-tier/), [agentdeals.dev comparison](https://agentdeals.dev/monitoring-comparison-2026)) **3. New Relic - the sleeper pick for agencies specifically.** Pricing is data + per-*user*, not per-host, which inverts in your favour: a handful of your engineers monitoring dozens of client apps and hosts costs about the same as monitoring three. 100GB/mo ingest free forever, then roughly $0.30-0.40/GB. Weakness is that per-client separation is by sub-account, which is less clean to hand off than a Sentry org. ([atatus.com/guides comparison](https://www.atatus.com/guides/atatus-vs-datadog-vs-new-relic-pricing/)) **4. Datadog - only for the enterprise client who asks for it by name.** Best-in-class breadth and the multi-org/partner management you'd want, but ~$15/host infra + ~$31/host APM plus indexed spans and $0.10/GB logs means it's not something you absorb into a retainer. Use it where the client pays for it directly on their own account and you're a user. ([dupple.com/learn](https://dupple.com/learn/best-application-monitoring-tools)) **5. Better Stack - the client-facing layer on top of whichever APM you choose.** Uptime, on-call, incident management, and status pages, with white-labelling on higher tiers. Agencies get more retainer-renewal value from a branded status page and a monthly "99.98%" report than from flame graphs the client will never open. ([cubeapm.com/blog/betterstack-pricing-review](https://cubeapm.com/blog/betterstack-pricing-review/)) **6. Checkly - if client sites have critical flows (checkout, signup, booking).** Playwright-based synthetic monitoring as code, so checks live in the client's repo and get versioned and reviewed like everything else. Catches the "form silently broke" class of failure that APM alone misses because nothing errored. ([trustradius.com/products/checkly](https://www.trustradius.com/products/checkly)) **7. Raygun - good middle ground when Datadog is overkill and Sentry's tracing isn't enough.** Error/crash reporting plus APM plus real-user monitoring, volume-priced, and the reports are legible enough to forward to a non-technical client. ([capterra.com/p/159822/Raygun](https://capterra.com/p/159822/Raygun/)) **8. ManageEngine Applications Manager or Site24x7 - if you're closer to an MSP than a dev shop.** These are the ones built for multi-tenant from the ground up: code-level visibility across Java/.NET/PHP/Node/Python/Ruby, per-tenant dashboards, white-label, and a self-hostable option if a client has data-residency rules. Less loved by developers, far better at "40 tenants, one console." ([manageengine.com MSP observability](https://www.manageengine.com/full-stack-observability-msp/application-performance-monitoring.html)) Two things worth doing regardless of which you pick: **instrument with OpenTelemetry** rather than a vendor agent, so a client's switch of tooling costs you a config change instead of a project; and **keep the account in the client's name with you as admin** where the client is paying, so monitoring never becomes a hostage in an offboarding conversation. If you want one answer and no further thinking: Sentry per client org + Better Stack for uptime and status pages, add Checkly for clients with revenue-critical flows. That combination covers the vast majority of agency work for well under what a single Datadog host costs.
