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

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - my default for most agencies.
2. New Relic mentioned
   New Relic - best value if you need real full-stack APM.
3. Datadog compared
   For 1-5 devs it typically lands ~$200-400/mo vs Datadog's $300-800.
4. Better Stack mentioned
   Better Stack or UptimeRobot - pair one of these with whatever you pick above.
5. UptimeRobot mentioned
   Better Stack or UptimeRobot - pair one of these with whatever you pick above.
6. White-label mentioned
   Clients don't ask "what's my p99," they ask "was the site down." White-label status pages on a client's own domain are the single highest-perceived-value monitoring thing you can ship.
7. Visual Sentinel mentioned
   Agency-specific alternatives in this lane: Visual Sentinel ($149/mo, 300 monitors, 50 white-labeled status pages) or Sentinel ($59/mo Business tier with branded client reports).
8. Sentinel mentioned
   Agency-specific alternatives in this lane: Visual Sentinel ($149/mo, 300 monitors, 50 white-labeled status pages) or Sentinel ($59/mo Business tier with branded client reports).
9. Grafana Cloud mentioned
   Grafana Cloud or SigNoz (OpenTelemetry-based) - the strategic play.
10. SigNoz mentioned
    Grafana Cloud or SigNoz (OpenTelemetry-based) - the strategic play.
11. OpenTelemetry mentioned
    Grafana Cloud or SigNoz (OpenTelemetry-based) - the strategic play.
12. Skip Dynatrace mentioned
    Skip Dynatrace and Splunk APM unless you have a specific enterprise client whose procurement already mandates them.
13. Dynatrace mentioned
    Skip Dynatrace and Splunk APM unless you have a specific enterprise client whose procurement already mandates them.
14. Splunk mentioned
    Skip Dynatrace and Splunk APM unless you have a specific enterprise client whose procurement already mandates them.

The answer, as recorded

## Short answer Agencies have a different problem than a single product team: you need **per-client data isolation, per-client billing, and something a non-technical client will actually look at** - not the deepest trace waterfall. Here's what I'd actually pick, in order: **1. Sentry** - my default for most agencies. Each client gets its own organization or project, errors come with the stack trace and the release that broke it, and tracing/performance is bundled. Pricing is usage-based from ~$26/mo with *unlimited users* (+$40/mo per active contributor), which is the key detail for agencies - you don't pay per seat for a rotating cast of contractors. Weakness: it's app-level, not infrastructure. **2. New Relic** - best value if you need real full-stack APM. One ingest-based bundle ($0.30/GB standard) covers APM, infra, logs, and traces instead of five separate SKUs, there's a genuinely usable free tier (100GB/mo + 1 full user forever), and you can put each client in its own Account under one Organization. For 1-5 devs it typically lands ~$200-400/mo vs Datadog's $300-800. Caveat: distributed tracing breaks across *Organizations*, so keep clients as Accounts, not separate orgs. **3. Datadog - but only via their Partner/MSP program** - the parent/child organization model is the most mature multi-tenant setup of anyone: child orgs can't see each other's data, independent billing and users. That's built for exactly your use case. The catch is cost compounding (per-host infra $15-23 + per-host APM $31-40 + logs + custom metrics), and SAML has to be configured per child org. Go here if you manage client *infrastructure*, not just their code. **4. Better Stack or UptimeRobot** - pair one of these with whatever you pick above. Clients don't ask "what's my p99," they ask "was the site down." White-label status pages on a client's own domain are the single highest-perceived-value monitoring thing you can ship. UptimeRobot from ~$7/mo, Better Stack from ~$85/mo. Agency-specific alternatives in this lane: Visual Sentinel ($149/mo, 300 monitors, 50 white-labeled status pages) or Sentinel ($59/mo Business tier with branded client reports). **5. Grafana Cloud or SigNoz (OpenTelemetry-based)** - the strategic play. Instrument client apps with OpenTelemetry once and you can switch or self-host backends per client without re-instrumenting. SigNoz can be self-hosted inside a client's own environment, which solves "our data can't leave our VPC" objections and lets you bill it as managed infrastructure rather than eating a SaaS seat. **Skip Dynatrace and Splunk APM** unless you have a specific enterprise client whose procurement already mandates them. The AI root-cause analysis is genuinely good, but the pricing floor and setup overhead don't amortize across many small clients. ## The one structural decision Don't resell one vendor account split by tags. Either (a) have each client own their account and add yourself as a user - they keep the data if they leave, you carry no billing risk, or (b) go through a real partner program (Datadog's) with proper child orgs. The middle path of one account with everyone's data commingled creates a liability problem the first time a client asks for an audit.
