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

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - the default, and probably your answer

   Rollbar - pick this if billing predictability matters more than ecosystem
3. GlitchTip mentioned
   GlitchTip (self-hosted) - the margin play
4. Railway mentioned
   ~$5-10/mo flat on a small VPS or Railway, unlimited projects, unlimited events.
5. Better Stack mentioned
   v6 shipped Feb 2026 with better stack traces and performance monitoring.
6. Honeybadger mentioned
   Honeybadger - for small agencies who want one vendor, not three
7. Ruby mentioned
   Rails/Ruby-leaning heritage but solid across the board now.
8. Raygun mentioned
   Raygun - if clients pay for reporting
9. Datadog mentioned
   Datadog - only if you're also managing infrastructure
10. UptimeRobot mentioned
    Agencies generally pair error monitoring with a separate client-facing layer - UptimeRobot's Scale plan (unlimited branded status pages on a custom domain) is the common choice, and Uptimeify offers unlimited sub-accounts with auto-generated white-labeled monthly PDFs.

The answer, as recorded

# Error monitoring for agencies The agency problem is different from the single-product problem: you have 15-60 codebases across clients, wildly uneven traffic, and you need per-client isolation plus something you can show a non-technical stakeholder. Here's what I'd actually reach for, in order. **1. Sentry - the default, and probably your answer** Broadest SDK coverage (every language and framework your clients' stacks will throw at you), unlimited projects on a single org with per-project teams and alert routing, and source maps that actually work for the JS-heavy builds most agencies ship. Pricing is a base plan ($26/mo Team, $80/mo Business annually) plus pooled reserved event volume, which is the right shape for agencies - one noisy client doesn't require its own plan. The catch: Business tier for SSO and advanced quota management, Seer AI debugging is +$40/contributor/mo, and replay beyond 50 sessions/mo bills extra. Watch the quota math per client or one bad deploy eats the pool. ([costbench](https://costbench.com/best/best-error-tracking-tools/), [toolradar pricing](https://toolradar.com/tools/sentry/pricing)) **2. Rollbar - pick this if billing predictability matters more than ecosystem** Genuinely the better fit for agency economics: it stops processing at your plan limit by default, on-demand events bill at the same per-event rate with no overage premium, and you can set dollar-capped overage budgets - so a client's runaway error loop can't produce a surprise invoice you have to eat or awkwardly pass on. Session replay is included in every plan including Free, and AI credits start at $9/mo rather than per-contributor. Smaller integration ecosystem than Sentry. ([Rollbar comparison](https://rollbar.com/blog/sentry-alternatives/), [Sentry vs Rollbar](https://costbench.com/compare/sentry-vs-rollbar/)) **3. GlitchTip (self-hosted) - the margin play** Drop-in Sentry SDK compatible, so you point the DSN elsewhere and change no code. ~$5-10/mo flat on a small VPS or Railway, unlimited projects, unlimited events. For an agency running 40 low-traffic client sites on retainer, this converts a four-figure annual SaaS line item into a rounding error, and you can bill monitoring as a retainer item at healthy margin. v6 shipped Feb 2026 with better stack traces and performance monitoring. Real cost: you now operate it, and you own the downtime. Bugsink is the comparable alternative. ([Railway deploy](https://railway.com/deploy/glitchtip-sentry-alternative), [Sentry alternatives](https://ssojet.com/blog/best-sentry-alternatives-error-tracking)) **4. Honeybadger - for small agencies who want one vendor, not three** Errors plus uptime monitoring plus cron/background-job checks in one product. For a shop under ~10 devs, consolidating three tools into one bill and one dashboard is worth more than Sentry's deeper feature set. Rails/Ruby-leaning heritage but solid across the board now. ([Rollbar roundup](https://rollbar.com/blog/best-error-monitoring-tools)) **5. Raygun - if clients pay for reporting** Errors, real user monitoring, and APM bundled at predictable pricing ($240/mo+). The RUM side gives you Core Web Vitals and real-user performance data that reads well in a monthly client report, which is where agencies actually extract value from monitoring. ([enterprise rankings](https://costbench.com/best/best-error-tracking-enterprise-2026/)) **6. Datadog - only if you're also managing infrastructure** From $31/host/mo, with error tracking folded into full-stack observability. Overkill and overpriced if you ship websites and apps; correct if your retainers include running clients' infrastructure and you need logs, traces, and errors correlated. ([costbench](https://costbench.com/best/best-error-tracking-enterprise-2026/)) **On white-label client reporting:** none of the above do it well. Agencies generally pair error monitoring with a separate client-facing layer - UptimeRobot's Scale plan (unlimited branded status pages on a custom domain) is the common choice, and Uptimeify offers unlimited sub-accounts with auto-generated white-labeled monthly PDFs. Treat these as complements to Sentry/Rollbar, not replacements - they monitor availability, not exceptions. ([UptimeRobot for agencies](https://uptimerobot.com/agency/), [Uptimeify](https://uptime.scale.sc/features)) **My recommendation:** Sentry Business if clients are paying for monitoring and you want zero operational burden; Rollbar if you've been burned by overage bills; GlitchTip if you have 20+ low-traffic client projects and someone on staff who's comfortable owning a VPS. One thing worth flagging since it's easy to get wrong: whichever you pick, put each client in a separate project with separate DSNs and scoped team access from day one. Retrofitting that separation after you've co-mingled clients in one project is painful, and it matters for data handling commitments in client contracts.
