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

Brands named, in the order the engine gave

1. APM mentioned
   Short version: it depends on whether "agency" means you ship client code (you want code-level APM) or you maintain client sites and need something to show clients.
2. Sentry recommended
   Sentry - my default recommendation for most agencies.
3. Scout APM mentioned
   Scout Monitoring (formerly Scout APM) - the best economics if you have many small-to-mid client apps.
4. Grafana Cloud mentioned
   Grafana Cloud - pick this if you want one platform spanning all clients and you care about not locking each client into a vendor.
5. OpenTelemetry mentioned
   It's OpenTelemetry-native, so instrumentation you write for a client is portable if they later move in-house - a real selling point in proposals.
6. Datadog mentioned
   Datadog - use it when a specific client is enterprise and wants full-stack correlation of traces, logs, infra, and RUM.
7. New Relic mentioned
   New Relic - worth knowing because of the pricing shape: $0.35/GB ingest after a 100 GB/month free allowance, plus per-user ($49/full user on Standard, $349 on Pro).
8. Dynatrace mentioned
   For enterprise clients who specifically ask, Dynatrace and IBM Instana are the AI/root-cause-analysis leaders and rate highest in analyst/G2 rankings - but they're client-budget tools, not agency-overhead tools.
9. IBM mentioned
   For enterprise clients who specifically ask, Dynatrace and IBM Instana are the AI/root-cause-analysis leaders and rate highest in analyst/G2 rankings - but they're client-budget tools, not agency-overhead tools.
10. IBM Instana mentioned
    For enterprise clients who specifically ask, Dynatrace and IBM Instana are the AI/root-cause-analysis leaders and rate highest in analyst/G2 rankings - but they're client-budget tools, not agency-overhead tools.
11. G2 mentioned
    For enterprise clients who specifically ask, Dynatrace and IBM Instana are the AI/root-cause-analysis leaders and rate highest in analyst/G2 rankings - but they're client-budget tools, not agency-overhead tools.
12. Hyperping mentioned
    Hyperping - explicitly built for agencies and web studios: all client sites in one dashboard, white-label status pages on your clients' custom domains.
13. Better Stack mentioned
    Better Stack - best combined uptime + log starter.
14. Dotcom-Monitor mentioned
    Dotcom-Monitor - the reseller play.
15. Rollbar mentioned

The answer, as recorded

Short version: it depends on whether "agency" means you ship client code (you want code-level APM) or you maintain client sites and need something to show clients. Here's the order I'd actually recommend, with both cases covered. ## If you build and run client applications **1. Sentry** - my default recommendation for most agencies. Error tracking plus tracing/performance in one tool, SDKs for 30+ languages, ~10 minutes to instrument, and $26/mo entry. The agency-relevant catch: billing is per *organization*, not per project, so you either pool all clients into one org (cheap, but one shared bill and shared access) or spin up an org per client (clean handoff, separate invoices, more admin). There's a long-standing feature request for per-project billing that still isn't shipped. For client work I'd lean toward one org per client and have them own the subscription - it means no migration when the engagement ends. **2. Scout Monitoring (formerly Scout APM)** - the best economics if you have many small-to-mid client apps. Every plan, including free, includes **unlimited apps and unlimited users**, and pricing is by transaction volume rather than per host or per seat. Free tier is 300K transactions/mo; paid starts at $19/mo, with the "Production Ready" tier around $59/mo annual ($98 monthly) for 1.2M transactions. Strongest on Rails, Django, Laravel, Node, Phoenix - N+1 query and memory-bloat detection are genuinely good. If you run 15 client Rails apps, this is the one that doesn't multiply your bill by 15. **3. Grafana Cloud** - pick this if you want one platform spanning all clients and you care about not locking each client into a vendor. The free tier is unusually real (10K metric series, 50 GB logs, 50 GB traces, 14-day retention, 3 users), paid starts at $19/mo plus usage. It's OpenTelemetry-native, so instrumentation you write for a client is portable if they later move in-house - a real selling point in proposals. Downside: usage-based billing can surprise you, and you'll build more yourself. **4. Datadog** - use it when a specific client is enterprise and wants full-stack correlation of traces, logs, infra, and RUM. Don't standardize your agency on it: APM is ~$31/host/mo *on top of* separately-priced infra and log modules, which destroys margins across many small apps. The right pattern is Datadog in the client's own account, billed to them, with you as a user. **5. New Relic** - worth knowing because of the pricing shape: $0.35/GB ingest after a 100 GB/month free allowance, plus per-user ($49/full user on Standard, $349 on Pro). The free tier with one full user is a legitimately useful way to monitor a couple of client apps at zero cost. It gets bad fast once several engineers need full-platform access. For enterprise clients who specifically ask, **Dynatrace** and **IBM Instana** are the AI/root-cause-analysis leaders and rate highest in analyst/G2 rankings - but they're client-budget tools, not agency-overhead tools. ## If you need client-facing monitoring as a deliverable **6. Hyperping** - explicitly built for agencies and web studios: all client sites in one dashboard, white-label status pages on your clients' custom domains. The simplest way to turn "we monitor your site" into a line item. **7. Better Stack** - best combined uptime + log starter. Free tier covers 10 monitors with 3-minute checks; logs at $0.10/GB ingest. Good when you want alerting plus a little log search without standing up Grafana. **8. Dotcom-Monitor** - the reseller play. Full white-label across PDF reports, live dashboards, and data feeds, so the monitoring looks like your product. Worth it only if you're actually charging for monitoring as a recurring service. ## What I'd do Standardize on **Sentry for errors + Scout for APM** as your internal stack (both have unlimited-user or cheap entry plans and won't scale with client count), add **Hyperping** if you sell uptime reporting, and put **Datadog or Dynatrace in the client's own account** whenever a client is large enough to want it. Avoid per-host pricing anywhere you're absorbing the cost yourself - that's the single mistake that makes agency monitoring unprofitable.
