Sentry vs Rollbar: Which Error Tracker Fits Your Team?

Sentry is the better default if you want errors, performance traces, session replays and logs in one place. Rollbar is the better fit if your main pain is “what did the last deploy break?” and you want predictable, occurrence-based billing. Both catch exceptions in production and tell you where in the code they happened. They differ in scope, pricing mechanics and how much setup they ask of you.

We build and run web apps and platforms for startups and teams in Switzerland, so we see both tools in real projects. This comparison is written from that angle: a small team, limited engineering time, and a client or investor who will eventually ask where your user data goes.

TL;DR

• Pick Sentry when you want one tool for errors, tracing, replays, logs and cron or uptime checks, and you are willing to model your data volumes first.
• Pick Rollbar when you mainly need error grouping, deploy tracking and a simple occurrence-based price, and you do not need a full observability suite.
• The pricing trap is volume, not the subscription. Sentry meters several data types separately, and once your budget is used up, data is dropped for the rest of the billing cycle.
• Both have free entry points, so run each on a real staging environment for a week before paying.
• The tool matters less than the process: who reads the alerts, who fixes the issues, and how fast.

What each tool actually does

Both products capture unhandled exceptions from your code, group similar ones together, attach context (stack trace, browser, release, user) and alert you through email, chat or a ticketing tool. That core is the same, and for many early-stage products it is all you need.

The tools diverge in how far they go beyond that core.

Sentry: errors plus a wider debugging surface

Sentry started as error tracking and has grown into a broader platform. According to Sentry’s pricing documentation, it now combines errors with tracing, logs, metrics, replays, uptime and cron monitoring, profiling options and AI debugging. It is also open source at its core and can be self-hosted, as one 2026 head-to-head review notes.

That breadth is the main argument for Sentry. If a user reports “the checkout froze”, you can look at the error, the slow request behind it and a replay of the session without opening three tools.

The cost of breadth is more to configure and more to forecast. Sentry gives you fine control over grouping and filtering, but that control takes some effort to set up.

Rollbar: focused on errors and deploys

Rollbar positions itself around error monitoring and the deploy cycle. The same review describes its deploy tracking as the more direct of the two when your question is whether a release caused a problem. Rollbar’s grouping is also described as more plug-and-play, with the trade-off that it can occasionally hide edge cases.

Rollbar’s current pricing page is organized around occurrences, replays and credits rather than a long list of separate data categories. That makes the bill easier to reason about for a team whose only question is “how many errors do we send?”

Side-by-side comparison

Criterion	Sentry	Rollbar
Core job	Error monitoring plus tracing, logs, metrics, replays, uptime, cron	Error monitoring with strong deploy context
Free option	Developer plan, one user	Free plan, starting at 5,000 occurrences per month
Paid entry	Team at $26/month billed annually, Business at $80/month	Essentials and Advanced tiers, priced by occurrence and replay volume
How you pay	Reserved volume per data category, optional pay-as-you-go	Occurrences, replays and credits chosen on a slider
Self-hosting	Available	Primarily a hosted service
Breadth	Wide, one debugging surface	Narrower, error-centric
Setup effort	Higher, more to tune	Lower to start
Best fit	Teams that want consolidation	Teams that want simple error tracking

Treat the table as a starting point. Both vendors change plans often, so check the pricing pages on the day you decide.

Pricing: where the real cost hides

Sentry’s metered categories

As of October 2026, Sentry lists a free Developer plan, Team at $26/month when billed annually with default prepaid data, Business at $80/month and Enterprise by quote. New accounts get a 14-day trial, and displayed prices exclude sales tax, which matters for a Swiss company that will see VAT added on top.

The Team baseline includes unlimited users and integrations, 50K errors per month, 5M spans, 50 replays, 5 GB of logs, 5 GB of application metrics, one cron monitor, one uptime monitor and 1 GB of attachments.

The subscription is the small number. The catch, per Sentry’s billing docs, is that data beyond your reserved volume can go to pay-as-you-go, but once both the reserved volume and your pay-as-you-go budget are exhausted, monitoring data is dropped for the rest of the billing cycle. In practice that means a noisy bug on the 20th of the month can leave you blind on the 25th, right when you most need visibility.

A sensible way to avoid this:

1. Estimate your monthly error count from a week of staging or beta traffic.
2. Estimate spans (traces) separately. Tracing every request at 100% is rarely necessary; sample it.
3. Decide whether you need replays and logs at all in the first six months.
4. Set a pay-as-you-go budget that is high enough to survive a bad day, and set an alert on spend.
5. Use filtering and sampling to keep known-harmless errors out of your quota.

Rollbar’s occurrence model

Rollbar’s pricing page lets you set occurrences, replays and credits, and the plan price follows those settings. The free tier starts at 5,000 occurrences and 1,000 replays per month. Paid prices depend on the volume you pick: one third-party review reports $35/month for Essentials and $49.40/month for Advanced at 10,000 occurrences and 10,000 replays. Third-party figures lag behind vendor changes, so confirm on the vendor page.

The upside is a smaller number of dials. The downside is that if you later want tracing, logs and uptime, you will be buying another tool.

A worked comparison

Imagine a seed-stage SaaS with a React front end, a Node.js API and three developers.

• Month one to three: a few thousand errors, no real traffic. Either free plan covers you. Sentry’s free tier gives one user, so a team of three will move to a paid plan sooner. Sentry’s Team plan includes unlimited users.
• Month six: a few thousand daily active users, a couple of noisy third-party script errors. On Sentry, you tune filters and sample traces. On Rollbar, you watch occurrences and adjust the slider.
• Month twelve: you want to understand slow checkout requests. Sentry already has tracing. With Rollbar you would add an APM tool.

The lesson: the cheaper tool at month one is not necessarily the cheaper stack at month twelve.

Data location, privacy and Swiss clients

If you sell to Swiss or EU companies, error tracking is a data-processing question. Stack traces and breadcrumbs often contain email addresses, IDs or fragments of form input. Before choosing, check:

• Where the vendor stores your data and whether you can pick the region.
• Whether a data processing agreement is available.
• How long data is kept. Sentry documents retention periods that vary by plan tier and data type.
• How you scrub personal data before it leaves your servers.

Rollbar publishes a GDPR page describing its approach for companies that process data of EU residents. Sentry’s self-hosted option gives you the most control, but you then own the servers, upgrades and uptime of your monitoring system. For a small team, that is often a poor trade.

The same logic applies when your product includes AI features. Failures there are often behavioral rather than a thrown exception, so classic error tracking will not see them. If that is your situation, it helps to read how AI incidents are reported and mapped to OECD, ETSI and NIST frameworks and decide what you need to log beyond stack traces.

For regulated customers such as banks, expect a security questionnaire. Having a documented tool, retention setting and scrubbing rule ready will save you days.

How to choose: five questions

1. Do we need more than errors? If you want tracing, replays and logs together, Sentry. If errors alone are enough, Rollbar is simpler.
2. Who will own the tool? A tool nobody tunes becomes an inbox of ignored alerts. Sentry rewards a person who tunes it. Rollbar asks for less tuning.
3. How spiky is our traffic? Spikes hurt on both, but Sentry’s separate quotas need more forecasting.
4. Which languages and frameworks do we use? Both cover the mainstream web stacks. One comparison on StackShare says Rollbar supports more languages, so check your exact SDK before deciding.
5. What does procurement require? Self-hosting, data region and retention can decide the matter regardless of features.

A short rule of thumb: a product team of two to ten people who want one pane of glass should start with Sentry and keep sampling conservative. A team with a stable, mature app and a tight budget that only wants to know about new exceptions after each release should look hard at Rollbar.

Beyond the tool: making monitoring useful

We have seen teams install an error tracker, get 400 alerts in the first week, mute the channel and never look again. The tool did its job. The process failed. A few habits make the difference:

• Tag every release. Both tools tie errors to releases. Without it you lose the main benefit.
• Route alerts by severity. New errors in production go to a channel somebody reads. Old noisy ones go to a weekly digest.
• Assign an owner per issue. An unowned error is a permanent error.
• Review weekly. Fifteen minutes, one person, close or ignore what is stale.
• Scrub personal data at the SDK level. Do not rely on dashboards to hide it later.
• Test your alerts. Throw a deliberate error in staging and see who gets notified, and how fast.

This is also why the choice between Sentry and Rollbar is less decisive than it feels. Either one, set up well and watched by a named person, beats the other set up carelessly.

Where we come in

Ampersand is a small Zurich studio that builds websites, web applications and platforms, with senior engineers involved from the first conversation to handover. Monitoring is part of how we ship software that stays reliable: we choose and configure the error tracker with you, wire it into your release process and make sure alerts reach someone who can act on them.

If you want it handled after launch, our pricing page lists a Run & monitor plan at 750 CHF per month, alongside advisory options such as Guidance at 799 CHF per month for teams that want senior technical input on choices like this one. If you would first like to see what we have built, our project overview shows our work. We aim for your independence, not lock-in, so any setup we do is documented and yours to keep.

FAQ

Is Sentry better than Rollbar?

Neither wins on every point. Sentry is broader, combining errors with tracing, replays, logs and more, which suits teams wanting one debugging surface. Rollbar is narrower and often simpler to run, which suits teams that mainly want error tracking tied to deploys.

Is Sentry free?

Yes, up to a point. Sentry offers a free Developer plan for solo developers on small projects, limited to one user. Team plans start at $26/month billed annually, and the displayed prices exclude sales tax.

Does Rollbar have a free plan?

Yes. Rollbar’s pricing page starts at 5,000 occurrences per month and 1,000 replays on the free setting. Paid plans scale with the occurrence and replay volume you choose.

What happens if I exceed my Sentry quota?

Extra data can be covered by pay-as-you-go if you set a budget. If both the reserved volume and that budget run out, Sentry drops monitoring data for the rest of the billing cycle. Set spend alerts and sample your traces to avoid it.

Do I need both tools?

Almost never. Running two error trackers doubles the alert noise and the configuration work. Pick one, run it well and revisit the choice only if your needs change, for example when you need tracing or self-hosting.
