The answer, as recorded

## Best error monitoring for agencies The agency problem is different from the in-house problem: you have many small codebases instead of one big one, contractors and client stakeholders cycling in and out, and volume you can't forecast because one client's bad deploy can blow your budget. That shapes the ranking. **1. Sentry** - The default, and the right default for most agencies. Broadest SDK coverage (JS frameworks, PHP/Laravel, Rails, Python, mobile, everything), source maps and release tracking that actually work, and session replay so you can see what the client's user did before the crash instead of trading screenshots. Seats are unlimited on Team and above, so adding a client's internal dev to one project costs nothing. The catch: per-event pricing meters into pay-as-you-go past your quota, so a runaway client project can produce a surprise bill. Set per-project spend caps and rate limits on day one. ([Better Stack](https://betterstack.com/community/comparisons/error-tracking-tools/), [Rollbar](https://rollbar.com/blog/sentry-vs-rollbar-pricing-the-hidden-cost-of-expanding-beyond-error-monitoring/)) **2. Rollbar** - The best structural fit for the agency model specifically. Unlimited projects, unlimited users, never per-seat, on every plan - which matters enormously when you're running 30 client projects with 3 stakeholders each. Starts around $13/mo. Grouping and deduplication are strong, so low-value noise from a dozen small sites doesn't drown the real incidents. Pick this over Sentry if your portfolio is wide and shallow. ([Rollbar pricing](https://rollbar.com/pricing-for-agents), [TrackJS comparison](https://trackjs.com/compare/rollbar-vs-sentry/)) **3. Honeybadger** - Choose this when budget predictability beats feature depth. $26/mo Team includes 50k errors, and instead of metering you past the limit it processes to 125% and then stops accepting events. You get incomplete data rather than a $4,000 invoice - which is the correct tradeoff when you're absorbing the monitoring cost into a fixed retainer and can't pass overages through. Bundles uptime and cron monitoring too, so it replaces two line items. Rails/Elixir/PHP-leaning. ([Netwarden](http://netwarden.com/blog/sentry-alternatives-without-per-event-bills/), [LightTrace](https://light-trace.robomiri.com/blog/honeybadger-alternatives/)) **4. WP Umbrella** - If you're a WordPress agency, this beats all of the above and it isn't close. PHP error logs, uptime, performance, vulnerability scans, backups, and one-click updates with rollback across every client site in one dashboard - plus genuinely polished **white-label client reports**, which is the thing generic APM tools do not do and which is often what you're actually selling. Pair it with Sentry only if you're also shipping custom plugins or headless front ends. ([Guideflow](https://www.guideflow.com/blog/wordpress-management-tools), [WPMet](https://wpmet.com/best-wordpress-site-monitoring-tools/)) **5. LogRocket** - Worth a seat for client-facing debugging rather than portfolio-wide coverage. Frontend session replay plus error context means when a client emails "the checkout is broken," you watch the actual session instead of running a discovery call. Expensive per project, so deploy it on the two or three accounts where disputes are costly. ([Sauce Labs](https://saucelabs.com/resources/blog/the-best-error-reporting-and-crash-monitoring-tools-of-2026)) **6. Bugsnag / Firebase Crashlytics** - Mobile only. Bugsnag's stability-score model (free up to 7,500 events, Team ~$59/mo) gives you a single release-health number that's easy to put in front of a non-technical client. Crashlytics is free and fine for Android/iOS if you're already in the Firebase stack and don't need the reporting polish. ([Better Stack](https://betterstack.com/community/comparisons/error-tracking-tools/)) **7. AppSignal / Raygun** - Consolidation plays. Both fold error tracking, APM, uptime, and RUM into one bill, which is worth it if you're currently paying for three tools. Raygun has the better cross-platform story (web plus mobile crash reporting); AppSignal is the nicer product if you're Ruby/Elixir/Node. Skip Datadog unless you're also managing client infrastructure - it's priced and built for enterprise platform teams, not agencies. ([Better Stack](https://betterstack.com/community/comparisons/error-tracking-tools/)) **What I'd actually do:** Sentry as the standard across client projects with hard per-project spend caps, or Rollbar instead if your client count is high and each project is small. Add WP Umbrella if WordPress is a meaningful share of the book. Bill monitoring through as a line item on the retainer rather than absorbing it - it makes the cap question moot.
