The question asked, verbatim: best error monitoring tools for agencies

Brands named, in the order the engine gave

1. Sentry mentioned
   - One project per client inside your agency's org - cheapest by far (paid Sentry tiers include unlimited projects and unlimited members, billed on event volume), but you own the data and can't cleanly hand it over when a client leaves.
2. Better Stack compared
   (Better Stack (https://betterstack.com/community/comparisons/error-tracking-tools/), middleware.io pricing breakdown (https://middleware.io/blog/sentry-pricing/))
3. GlitchTip mentioned
   GlitchTip or self-hosted Sentry - the margin play if you have ops capacity.
4. Self-hosted Sentry mentioned
   GlitchTip or self-hosted Sentry - the margin play if you have ops capacity.
5. Rollbar mentioned
   Rollbar - the one to price against Sentry.
6. Bugsnag mentioned
   Bugsnag (Insight Hub) - pick this if your client work is mobile-heavy.
7. AppSignal mentioned
   AppSignal - good fit if you're a Rails/Elixir/Node shop.
8. LogRocket mentioned
   LogRocket - add-on, not a replacement.
9. Firebase Crashlytics mentioned
   Firebase Crashlytics - free, and the right answer for client mobile apps on retainer where nobody will pay for monitoring.
10. Datadog mentioned
    Datadog - only if a client already runs it or you're servicing enterprise infra.
11. Pulsetic mentioned
    There you'd want Pulsetic, Sentinel (~$59/mo, 300 monitors, branded reports), or Uptimeify (unlimited client sub-accounts, fully white-labeled under your domain).
12. Sentinel mentioned
    There you'd want Pulsetic, Sentinel (~$59/mo, 300 monitors, branded reports), or Uptimeify (unlimited client sub-accounts, fully white-labeled under your domain).
13. Uptimeify mentioned
    There you'd want Pulsetic, Sentinel (~$59/mo, 300 monitors, branded reports), or Uptimeify (unlimited client sub-accounts, fully white-labeled under your domain).

The answer, as recorded

## The structural decision first For an agency the tool matters less than the account model, because it determines your margin and your exit. Two options: - **One project per client inside your agency's org** - cheapest by far (paid Sentry tiers include unlimited projects and unlimited members, billed on event volume), but you own the data and can't cleanly hand it over when a client leaves. - **One org per client** - clean handover and client-billable, but on Sentry each org needs its own subscription; they don't roll up under one bill ([Sentry Help Center](https://www.sentry.help/en/articles/13964757-can-i-have-multiple-organizations-for-one-Sentry-subscription)). Pick that before you pick a vendor. Now the tools: **1. Sentry** - the default, and what I'd actually start with. Best stack traces, issue grouping, release/deploy tracking, and session replay in one place; SDKs for every stack you'll meet in client work. Unlimited projects and seats on paid plans ($26/mo Team) means you can host 30 client apps on one bill. Its weakness is exactly the agency case: no multi-org rollup billing. ([Better Stack](https://betterstack.com/community/comparisons/error-tracking-tools/), [middleware.io pricing breakdown](https://middleware.io/blog/sentry-pricing/)) **2. GlitchTip or self-hosted Sentry** - the margin play if you have ops capacity. Sentry-SDK-compatible, so client code needs no changes if you later migrate; one VPS covers unlimited client projects at flat cost. You trade your time for the subscription. Worth it above roughly 15-20 client apps. **3. Rollbar** - the one to price against Sentry. Entry tier is $9/mo vs Sentry's $26, which matters when you're spinning up a separate account per client. Caveat: billing is three-dimensional (events + session replays + AI credits), so per-client costs are harder to forecast and quote. ([Rollbar](https://rollbar.com/blog/sentry-alternatives/)) **4. Bugsnag (Insight Hub)** - pick this if your client work is mobile-heavy. Best-in-class stability scores and release health for iOS/Android; free tier for solo, $20/mo Select upward. Weaker than Sentry for web/frontend. ([tech-insider comparison](https://tech-insider.org/sentry-vs-bugsnag-vs-rollbar-2026/)) **5. AppSignal** - good fit if you're a Rails/Elixir/Node shop. Errors, APM, logs, uptime and host metrics in one tool at one price, which collapses three subscriptions per client into one. Narrower language support. ([Better Stack](https://betterstack.com/community/comparisons/error-tracking-tools/)) **6. LogRocket** - add-on, not a replacement. Session replay with full error context is what wins arguments with non-technical clients who say "it's broken" and nothing else. Expensive per seat; buy it for the accounts where scope disputes cost you money. **7. Firebase Crashlytics** - free, and the right answer for client mobile apps on retainer where nobody will pay for monitoring. Use it as your floor, not your standard. **8. Datadog** - only if a client already runs it or you're servicing enterprise infra. Error Tracking is a feature of a large observability platform; overkill and overpriced for a portfolio of small sites, and the consumption billing is hostile to fixed-fee retainers. ([Sauce Labs](https://saucelabs.com/resources/blog/the-best-error-reporting-and-crash-monitoring-tools-of-2026)) ## One clarification If by "error monitoring" you actually mean client-facing site health - uptime, SSL expiry, broken assets, branded monthly PDFs - that's a different category and none of the above do it well. There you'd want **Pulsetic**, **Sentinel** (~$59/mo, 300 monitors, branded reports), or **Uptimeify** (unlimited client sub-accounts, fully white-labeled under your domain). ([Pulsetic](https://pulsetic.com/white-label-website-monitoring/), [Sentinel](https://sentinel.rootstuff.io/blog/white-label-uptime-monitoring), [Uptimeify](https://uptimeify.io/)) Most agencies end up running one from each column: Sentry for the developers, a white-label uptime tool for the client report.
