The answer, as recorded

## The short answer For most agencies, **Sentry** first, then **Honeybadger** or **Rollbar** depending on your billing style, with **GlitchTip** as the cost escape hatch and **Raygun** if unlimited apps matter more than anything else. The agency-specific constraint that changes the ranking versus a normal "best of" list: you have many small codebases rather than one big one, developers rotate across clients, and at some point you may need to hand an account over to the client. So per-project fees and per-seat fees hurt you much more than event volume does. **1. Sentry** - the default, and the one your clients' in-house devs will already recognize when you hand off. Broadest SDK coverage (every framework you'll get handed), source maps, releases, session replay. The catch for agencies: event quota is pooled across the whole org, so all your clients draw from one bucket and a single noisy client site can eat the month. Plan for per-project rate limits and spike protection from day one, and price the Team plan (~$26/mo base) as a floor, not a ceiling. ([Last9 pricing breakdown](https://last9.io/blog/sentry-pricing/), [SigNoz](https://signoz.io/guides/sentry-pricing/)) **2. Honeybadger** - the best fit if your pain is "20 clients, 20 projects." Team plan is ~$26/mo with **unlimited projects and unlimited users**, plus uptime checks and cron/heartbeat monitoring in the same product. Flat and predictable, which is what you want when you're rebilling clients a fixed retainer. Weaker than Sentry on frontend/mobile depth; strongest on Ruby/Rails and Elixir shops. ([MakerStack review](https://makerstack.co/reviews/honeybadger-review/), [Better Stack](https://betterstack.com/community/comparisons/honeybadger-alternative/)) **3. Rollbar** - cheapest credible entry point (~$13-16/mo for 25k events, 90-day retention) and usage-based rather than seat-based, which suits lumpy agency workloads where three clients are quiet and one just launched. Good grouping and deploy tracking. ([TrackJS comparison](https://trackjs.com/compare/rollbar-vs-bugsnag/), [Sublyzer](https://www.sublyzer.com/blog/rollbar-alternatives)) **4. GlitchTip** - run this when the Sentry bill stops making sense. It's Sentry-SDK-compatible, so you switch by changing the DSN, no code changes; self-hosted is free and unlimited, and hosted starts around $15/mo with unlimited projects and members. Realistically it's ~$5-10/mo of infra on a small box. The tradeoff is you're now the ops team for it, and you lose performance monitoring and replay. ([CubeAPM](https://cubeapm.com/blog/glitchtip-pricing-and-review/), [Sentry vs GlitchTip](https://aiopentec.github.io/opensource-alternative-finder/sentry-vs-glitchtip/)) **5. Raygun** - **unlimited apps and unlimited members on every tier**, which is structurally the most agency-friendly pricing model in the category. Crash Reporting starts ~$40/mo annual for 100k errors, and it bundles RUM and APM if you're selling performance work as a service line. Higher floor than the others, so it earns its place once you're past a handful of clients. ([Raygun pricing](https://raygun.com/pricing)) **6. Bugsnag (now Insight Hub, SmartBear)** - pick this over Sentry only if your book of business is mobile-heavy. Stability scores per release are genuinely the right abstraction for "is this client's app healthy," and it's a cleaner story in a client report than raw error counts. Paid plans start ~$59-65/mo. ([TrackJS](https://trackjs.com/compare/bugsnag-vs-rollbar/)) **7. LogRocket** - not really an error tool, but worth naming because agencies live or die on client disputes. Session replay with the errors attached lets you answer "the site is broken" with a video instead of an argument. Expensive as a primary tool; excellent as a second one on your two or three biggest accounts. ([Sauce Labs roundup](https://saucelabs.com/resources/blog/the-best-error-reporting-and-crash-monitoring-tools-of-2026)) ## One thing the roundups miss None of the above white-labels well. If a chunk of your retainer value is the monthly client-facing report, pair your error tool with a white-label uptime/status layer - **Pulsetic**, **Hyperping**, or **Sitewatch** - which give you branded status pages on `status.clientsite.com` and reports that look like your deliverable rather than a vendor export. Error monitoring is for you; the status page is for them. ([Pulsetic](https://pulsetic.com/white-label-website-monitoring/), [Hyperping](https://hyperping.com/use-cases/agencies), [Sitewatch](https://getsitewatch.com/features/white-label-reports)) **If you want a single pick:** Sentry for the client work, one org per client where the client can be made owner at handoff, with per-project rate limits set on day one. Move the long-tail maintenance sites to GlitchTip once the pooled quota starts costing more than a junior dev's afternoon. Two caveats on the pricing above: these figures come from third-party comparison sites and move frequently, so confirm on each vendor's own pricing page before you build them into a retainer. And Sentry's seat model means the ~$26 base is not the whole bill for a team of any size.
