TL;DR

The best error tracking tools in 2026 are Sentry as the default for almost every team, Rollbar for aggressive automatic grouping and deploy tracking, Bugsnag for mobile-heavy products with its stability score model, Datadog Error Tracking if you already run Datadog for everything else, and Honeybadger if you want errors, uptime checks and a status page on one flat bill. Sentry's free tier covers 5,000 errors a month, which is enough to start properly.

5 tools compared: Sentry, Rollbar, Bugsnag, Datadog Error Tracking, Honeybadger
Rollbar (best for: Teams that want automatic grouping and deploy correlation): Free plan (5,000 occurrences a month); paid plans priced by event volume
Bugsnag (best for: Mobile-first products): Free plan (7,500 events a month); paid plans, part of SmartBear
Datadog Error Tracking (best for: Teams already standardised on Datadog): $25/mo flat under 50,000 errors (annual); included with Datadog APM and RUM

The gap between an exception happening in production and an engineer knowing about it used to be a customer support ticket.

Error tracking closed that gap, and the modern versions do considerably more: they group thousands of occurrences into one issue, attach the stack trace with your source mapped back to real filenames, record what the user was doing, and tell you which deploy introduced it.

The differences between the tools are less about capability now and more about noise, pricing model and how much context arrives with each alert.

Datadog Error Tracking

Best for: Teams already standardised on Datadog

Pricing$25/mo flat under 50,000 errors (annual); included with Datadog APM and RUM

PricingFrom $26/mo (Team, 50K errors); free Developer plan with 5,000 errors a month

What it is

An error tracking tool captures unhandled exceptions and logged errors from your application, deduplicates them into issues, and enriches each one with context: stack trace, source maps, release version, environment, user and request data, breadcrumbs of what happened before, and often a session replay.

It then routes alerts to the humans who can fix them, ideally only for things that matter.

Why it matters

Two reasons, and the second is the one teams underrate. The first is detection: you find out about failures in minutes rather than when someone complains.

The second is triage: a good tool tells you that this exception affects 340 users on one browser version since Tuesday's deploy, which turns an unbounded investigation into a bounded one. Without that, engineers spend the expensive part of the day trying to reproduce something instead of fixing it.

Key features to look for

Grouping quality

How well the tool collapses thousands of occurrences into one issue without merging genuinely different bugs. This is the single biggest quality difference between platforms and it is hard to evaluate from a marketing page.

Source maps and release tracking

Minified stack traces mapped back to your real source, tied to the release that introduced them. Without release association, the question of which deploy broke it stays unanswered.

Context and breadcrumbs

What the user did in the minutes before the error, which request, which feature flags. This is what removes the need for a reproduction.

Noise control

Inbound filters, rate limits, spike protection and the ability to ignore known-benign errors. An error tracker nobody looks at is worse than none, and noise is why that happens.

Pricing model

Per-error volume, per-user, or bundled into an observability platform. Volume-based plans need spike protection or an incident can generate the bill as well as the outage.

Pricing

Sentry, Honeybadger, Rollbar and Datadog publish dollar prices, Bugsnag sends you to a calculator on its site, and Sentry Enterprise is a custom quote.

The cheapest credible entry is Sentry's free Developer plan, with Team billed annually as the first paid plan; Honeybadger Team matches that entry price with 50,000 errors, unlimited users and uptime monitors included. Costs jump at Sentry Business, $80 a month billed annually, which adds unlimited dashboards and anomaly detection.

Rollbar's free plan covers 5,000 occurrences a month and paid plans scale by event volume (Rollbar's own example is $29 a month for 50,000 events on Essentials), while Bugsnag's free plan covers 7,500 events a month. Datadog Error Tracking is included with APM and RUM, and standalone it is a flat $25 a month under 50,000 errors on annual billing.

Plan	Price	Best for
Sentry Developer	$0	1 user, 5k errors/mo, 5M spans, 50 replays
Sentry Team	$26/mo billed annually	Unlimited users, 50k errors

Sentry Enterprise	Custom quote	Enterprise plan at a custom price
Rollbar Essentials	$29/mo at 50K events	Priced by event volume; free plan covers 5,000 occurrences
Bugsnag paid plans	Prices on their site	Free plan covers 7,500 events a month, part of SmartBear
Datadog Error Tracking	$25/mo under 50K errors	Annual rate, $36 on demand; included free with APM and RUM

Honeybadger Team	From $26/mo	Unlimited users, 50K errors, uptime monitors, status page

Mistakes to avoid

×Alerting on every new error. Within two weeks nobody reads the channel, and the one alert that mattered scrolls past. Alert on rate, on new-since-deploy, and on user impact instead.

×Skipping source maps. A minified stack trace is nearly useless, and uploading source maps in CI takes an afternoon once.

×Not tagging releases. Without release association you cannot answer the most valuable question the tool can answer: which deploy caused this?

×Ignoring quota mechanics. On volume-priced plans, an incident that generates a million errors also generates a bill. Configure spike protection and rate limits before you need them.

Expert tips

→Set up source maps and release tagging in CI on day one, before you tune anything else. Everything else in the tool depends on those two.

→Triage the top five issues by user impact each week rather than by count. A crash affecting 200 users beats a noisy log line firing 50,000 times.

→Attach user context (an id, not personal data) so you can answer whether one customer is disproportionately affected.

→Aggressively ignore known-benign errors, such as browser extension noise and cancelled requests. Signal-to-noise is what determines whether anyone opens the tool in month three.

The bottom line

For nearly every team, start with Sentry: the free tier is genuinely usable at 5,000 errors a month, grouping quality is the best in the category, and the paid Team plan covers a real production application.

Pick Bugsnag if you ship mobile and want stability scores per release, Rollbar if automatic grouping and triage automation are your priority, and Datadog only if you already live there.

Whatever you pick, source maps and release tagging matter more than the choice itself.

Frequently asked questions

What is the best free error tracking tool?

Sentry's Developer plan is the strongest free option, covering 5,000 errors a month with full grouping, stack traces and 50 session replays for one user. Honeybadger's Developer plan matches that 5,000-error allowance for one user, and self-hosted Sentry is the route if you want unlimited volume and are willing to run it yourself.

How much does Sentry cost?

The Developer plan is free with 5,000 errors a month for a single user. Team is $26 a month billed annually with unlimited users and 50,000 errors, Business is $80 a month billed annually adding unlimited dashboards and anomaly detection, and Enterprise is custom. Additional volume is available as a paid add-on.

What is the difference between error tracking and APM?

Error tracking captures exceptions and groups them into fixable issues with stack traces and user context. APM measures performance: latency, throughput and where time is spent across services. They answer different questions, which is why platforms increasingly bundle both, but a slow endpoint and a crashing endpoint are separate problems.

Is Sentry or Rollbar better?

Sentry is the broader and more widely adopted platform, with better SDK coverage, an open-source core and performance monitoring plus session replay in the same product. Rollbar is more narrowly focused on error tracking with excellent automatic grouping and triage automation. If you want one tool for errors, performance and replay, choose Sentry.
