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

Brands named, in the order the engine gave

1. Sentry recommended
   Sentry - the default, and for most agencies the right answer.
2. Rollbar recommended
   Rollbar - the pick when each client has its own small retainer and you need the per-project cost to be near-trivial.
3. BugSnag recommended
   BugSnag (now SmartBear Insight Hub) - only if you do mobile or heavy client-side app work.
4. Honeybadger recommended
   Honeybadger - best fit for a small shop on Rails, Laravel, or similar.
5. Self-hosted Sentry recommended
   Self-hosted Sentry or GlitchTip - worth it at ~15+ client projects, where per-event SaaS pricing starts to lose to a fixed server bill, or when a client contract demands EU/on-prem data residency.
6. GlitchTip recommended
   Self-hosted Sentry or GlitchTip - worth it at ~15+ client projects, where per-event SaaS pricing starts to lose to a fixed server bill, or when a client contract demands EU/on-prem data residency.
7. Raygun recommended
   Raygun - pick this if performance reporting is part of what you sell.
8. Datadog recommended
   Datadog - only if you already run infrastructure retainers and want logs, APM, and errors in one pane.

The answer, as recorded

Searched; a chunk of what comes back for this query is SEO/affiliate content with invented-looking numbers, so I'd treat specific prices below as directional and confirm on the vendors' own pricing pages before committing. Here's what I'd actually recommend, in order: **1. Sentry** - the default, and for most agencies the right answer. The reason is specifically agency-shaped: paid plans include unlimited seats, so you can put every developer, PM, and the client's own technical contact in the account without the bill moving. You run one org with a project per client, errors stay cleanly separated, and quota pools across projects so a quiet client subsidizes a noisy one. SDK coverage (100+ platforms) means it's the one tool that covers whatever stack you inherited on the last project. Watch two things: event overages can spike nastily when a client ships a bad release, and the Seer AI debugging agent is a separate ~$40/contributor add-on.

Rollbar** - the pick when each client has its own small retainer and you need the per-project cost to be near-trivial. Cheapest serious entry point, the most generous free tier (useful for parking low-traffic client sites), and its grouping/dedup is genuinely good at keeping a queue you only glance at twice a week readable. It bundles session replay and AI credits into paid tiers rather than charging extra, which makes the bill more predictable than Sentry's as volume grows. ([rollbar.com/blog](https://rollbar.com/blog/sentry-alternatives-for-error-tracking/)) **3. BugSnag (now SmartBear Insight Hub)** - only if you do mobile or heavy client-side app work. Its differentiator is release health: a stability score per release, so you can give a client a defensible go/no-go on a rollout instead of a vibe. Weaker value for plain web work, and its per-feature pricing means you pay again for things Sentry and Rollbar bundle. ([rollbar.com/blog](https://rollbar.com/blog/bugsnag-alternatives/)) **4. Honeybadger** - best fit for a small shop on Rails, Laravel, or similar. It folds error tracking, uptime checks, and cron/background-job check-ins into one cheap bill, which covers roughly everything a maintenance retainer actually needs to monitor. Deliberately unsophisticated, which is the point: nothing to tune, no noise budget to manage. ([rollbar.com/blog](https://rollbar.com/blog/best-error-monitoring-tools/)) **5. Self-hosted Sentry or GlitchTip** - worth it at ~15+ client projects, where per-event SaaS pricing starts to lose to a fixed server bill, or when a client contract demands EU/on-prem data residency. GlitchTip is Sentry-SDK-compatible, so switching is a DSN change, not a migration. The tradeoff is that you now operate a service, and agencies are usually bad at that. **6. Raygun** - pick this if performance reporting *is* part of what you sell. It pairs crash reporting with real user monitoring and session-level drill-down, so the monthly client deck writes itself. Overkill if errors are all you need. ([rollbar.com/blog](https://rollbar.com/blog/best-error-monitoring-tools/)) **7. Datadog** - only if you already run infrastructure retainers and want logs, APM, and errors in one pane. Far too expensive and heavy to stand up per client site. ([rollbar.com/blog](https://rollbar.com/blog/best-error-monitoring-tools/)) One structural point that matters more than the tool choice: set these accounts up under the client's billing wherever you can, with you as an admin. Otherwise you absorb overage when their traffic spikes, and you own an awkward extraction problem the day the relationship ends.
