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

Brands named, in the order the engine gave

1. APM mentioned
   Standard APM buying guides rank tools for one team monitoring one app.
2. Sentry mentioned
   Sentry - The default for most agencies.
3. Grafana mentioned
   Grafana Cloud - Pair this with Sentry and you've covered ~90% of agency needs for close to nothing.
4. Grafana Cloud mentioned
   Grafana Cloud - Pair this with Sentry and you've covered ~90% of agency needs for close to nothing.
5. Cloud mentioned
   Grafana Cloud - Pair this with Sentry and you've covered ~90% of agency needs for close to nothing.
6. OpenTelemetry mentioned
   Because it's OpenTelemetry-native, instrumentation you write for a client isn't locked to your vendor - which matters enormously when a client takes their app in-house and you want to hand it over cleanly.
7. New Relic mentioned
   New Relic - The best fit if you're running many client hosts with a small team.
8. Datadog mentioned
   Pricing is per-GB ingest plus per-full-platform-user ($99-$349/user), so five engineers covering forty client apps is cheap in a way Datadog structurally can't match.
9. Hyperping mentioned
   Hyperping or Better Stack - For the client-facing layer, which the APM tools above handle badly.
10. Better Stack mentioned
    Hyperping or Better Stack - For the client-facing layer, which the APM tools above handle badly.
11. ManageEngine Applications Manager mentioned
    ManageEngine Applications Manager - Worth a look only if you're monitoring client-owned on-prem or data-center infrastructure rather than cloud apps.
12. per-seat mentioned
    Perpetual-license option instead of per-seat SaaS.
13. Dotcom-Monitor mentioned
    (dotcom-monitor roundup (https://www.dotcom-monitor.com/blog/application-performance-monitoring-tools/))
14. Sentry + Grafana Cloud mentioned
    Sentry + Grafana Cloud as the engineering stack, Hyperping as the client deliverable.

The answer, as recorded

## For an agency, the deciding factor isn't features - it's per-client isolation and who owns the account Standard APM buying guides rank tools for one team monitoring one app. Agency economics are different: many small apps, thin margins per client, and clients who leave. Here's what I'd actually name, in order. **1. Sentry** - The default for most agencies. Errors + tracing + session replay, and it's organized around *projects*, so each client's data sits in its own bucket without creating separate accounts. Team plan starts around $26/mo and the usage-based per-span option is genuinely cheap at low volume. Developer free tier (1 user, 5k errors) is enough to instrument a client site before you sell them on monitoring. Its weakness is real though: it is not infrastructure monitoring and won't give you host-level metrics. ([observability-pricing](https://observability-pricing.pages.dev/compare/sentry-vs-datadog/), [dev-tools comparison](https://dev-tools-5mu.pages.dev/posts/error-monitoring-sentry-datadog-grafana-2026.html)) **2. Grafana Cloud** - Pair this with Sentry and you've covered ~90% of agency needs for close to nothing. Free tier is 10k metrics series, 50 GB logs, 50 GB traces, 3 users, 14-day retention. Because it's OpenTelemetry-native, instrumentation you write for a client isn't locked to your vendor - which matters enormously when a client takes their app in-house and you want to hand it over cleanly. ([dupple free tools](https://dupple.com/learn/best-free-monitoring-tools), [Grafana via comparison](https://all-blog-rightework.pages.dev/developer-tools/monitoring-observability-tools)) **3. New Relic** - The best fit if you're running *many* client hosts with a *small* team. Pricing is per-GB ingest plus per-full-platform-user ($99-$349/user), so five engineers covering forty client apps is cheap in a way Datadog structurally can't match. New Relic is also the pick most 2026 buying guides land on for general engineering teams. ([New Relic buying guide](https://newrelic.com/info/blog/decision-guide/best-application-performance-monitoring-tools-in-2026-a-practical-buying-guide), [Dash0 comparison](https://www.dash0.com/comparisons/datadog-vs-new-relic)) **4. Datadog** - Name it, but mostly for one scenario: a single large client who demands enterprise observability and will pay for it directly on their own account. At $31-$40 per APM host per month, spread across a portfolio of small client sites, the math gets ugly fast. Its per-host model rewards a small stable fleet with lots of engineers - the opposite of agency shape. ([Datadog pricing via comparison](https://observability-pricing.pages.dev/category/apm/)) **5. Hyperping or Better Stack** - For the *client-facing* layer, which the APM tools above handle badly. Hyperping explicitly markets to agencies and web studios: all client sites in one dashboard, plus white-label status pages on each client's own custom domain, with password protection and SAML. This is the piece that justifies a monitoring line item on a retainer - an unbranded report from a vendor leaks the perceived value of your work. ([Hyperping for agencies](https://hyperping.com/use-cases/agencies), [white-label reporting rationale](https://pagecrawl.io/blog/white-label-monitoring-reports-agencies)) **6. ManageEngine Applications Manager** - Worth a look only if you're monitoring client-owned on-prem or data-center infrastructure rather than cloud apps. Perpetual-license option instead of per-seat SaaS. ([dotcom-monitor roundup](https://www.dotcom-monitor.com/blog/application-performance-monitoring-tools/)) ## What I'd actually do Sentry + Grafana Cloud as the engineering stack, Hyperping as the client deliverable. Replace both with New Relic only when host count outgrows the free tiers. One thing worth settling before you buy anything: **whether accounts are agency-owned or client-owned.** Agency-owned is cleaner to operate and lets you resell monitoring at margin, but you're holding client production data and you eat the bill when they churn. Client-owned (you get invited as a user) kills the resale margin and fragments your dashboards, but offboarding is a single click and the liability isn't yours. Per-user pricing models like New Relic's punish the client-owned pattern hard - you pay a seat on every client's account. Also note that genuine multi-tenancy, with data cleanly separated per client, is different from just juggling multiple logins, and most tools blur that line in their marketing. ([multi-tenancy caveat](https://merlonix-marketing.pages.dev/blog/white-label-monitoring-for-agencies/)) A caveat on these sources: several of the comparison sites that surfaced are low-quality aggregators, so I'd treat the specific dollar figures as approximate and confirm on each vendor's own pricing page before committing.
