Sentry Alternatives for Error Monitoring in 2026: Bugsnag, Rollbar, Datadog, and GlitchTip

Sentry is the default choice for a reason - most teams reach for it first and never revisit the decision. But "default" and "cheapest" or "best fit" aren't the same thing, and the reasons people actually go looking for a Sentry alternative usually fall into one of four buckets: the bill grew faster than expected, support response times don't match what an incident actually needs, error tracking is duplicating a bill you already pay elsewhere (Datadog), or you want the data on your own infrastructure. We checked live pricing from Sentry, Bugsnag, Rollbar, Datadog, and GlitchTip on 2026-07-12 to see which reason maps to which tool.

The numbers, no rounding

Here's what each vendor's pricing page actually says today, not what a comparison post from eight months ago said.

The pattern across all five: event or occurrence volume is what actually drives the bill, not seat count. Sentry is the only one of the five that also charges per user once you're past a certain scale (Business and Enterprise add per-seat considerations at higher volumes), but even there the headline number is tied to error volume first.

Sentry: the baseline you're comparing against

Sentry's current public tiers are Developer (free, 5k errors, 1 user), Team ($26/user/month billed annually, 50k errors, unlimited users, 90-day lookback), Business ($80/user/month billed annually, same 50k error allotment but deeper retention and unlimited dashboards), and a custom Enterprise tier. Every paid tier also carries pay-as-you-go charges for usage beyond the included quota - logs, metrics, and profiling are billed separately once you exceed what's bundled.

Two things worth flagging if you're pricing this out today. First, Sentry's pricing page shows a Monthly/Annual toggle, and the Team and Business prices displayed don't change between the two toggle states - $26 and $80 hold either way as shown on the page itself, though it's still worth confirming the exact terms at checkout since a pricing page display isn't a signed contract. Second, "unlimited users" on Team is a real advantage over Bugsnag and Rollbar's seat structure once your team grows past 5-6 people, since neither of the other two publishes an unlimited-seats plan at a comparable price point. If you want the deeper breakdown of what Sentry costs at different team sizes and where the Business tier's extra retention actually matters, our Sentry pricing page tracks the same numbers with per-seat math.

Bugsnag: usage-tiered, better support tier, no flat number to quote

Bugsnag's structure is Free (7.5k events/month, 1M spans, 7-day retention, 1 user), Select (50k-3M events/month depending on the tier you pick, 60-day retention, unlimited users), Preferred (adds automatic error assignment, premium support, dedicated CSM, SAML SSO), and Enterprise (custom, adds on-premises deployment).

The honest limitation here: Select and Preferred both display as "starting at $0/month" with a usage slider rather than a single published number, which tells you the real price depends on exactly how many events and spans you configure - there isn't a flat "$X/month" figure to put next to Sentry Team's $26 the way a lot of comparison posts imply. What Bugsnag does publish clearly is that both paid tiers include unlimited users (a genuine edge over per-seat pricing if you have a large team touching errors) and that Preferred adds SAML SSO, which Sentry also offers starting at Business. Dedicated customer support is a different story: Bugsnag reserves it for Enterprise, and so does Sentry - Sentry's Business tier doesn't include a technical account manager either, so that specific comparison is a wash rather than a Bugsnag advantage. If premium support response time is the actual reason you're leaving Sentry, price out Bugsnag directly at bugsnag.com/pricing against your real event volume rather than trusting a rounded estimate.

Rollbar: the cheapest way to see a real number, but only at the extremes

Rollbar's public tiers are Free ($0, 5,000 occurrences/month, 1,000 replays, 30-day retention), Essentials (credit-based, 10K-50M occurrence range, 90-day retention), Advanced (credit-based, same occurrence range, 180-day retention, adds Rollbar Analyze and SCIM provisioning), and Enterprise (custom, for teams past 80M events, fully custom retention).

Like Bugsnag, Rollbar doesn't show a flat monthly price for Essentials or Advanced on its pricing page - it's credit-based, and the credits map to a wide occurrence range (10K to 50M) that makes a single "starting price" claim misleading either way. What is clear: Rollbar's data retention scales with tier (30 days free, 90 days Essentials, 180 days Advanced), which matters if you're debugging intermittent issues that only resurface weeks later. If retention length is your switching driver more than raw price, that's a real differentiator against Sentry's 90-day cap on Team - but confirm current credit pricing directly at rollbar.com/pricing before assuming it beats Sentry on cost, since credits and occurrences don't convert 1:1 with Sentry's per-error counting.

Datadog: only makes sense if you already pay for APM

This is the one vendor on this list that doesn't sell error tracking as its own product. Datadog's Error Tracking ships included with APM and with Real User Monitoring + Session Replay - there's no "Error Tracking" line item you can buy on its own. APM itself starts at $31/host/month when bundled with Infrastructure Monitoring (billed annually; $48/host on-demand), with a standalone APM price of $36/host/month. Higher tiers keep that same bundled-vs-standalone split: APM Pro is $35/host/month bundled with Infrastructure Monitoring ($41/host/month standalone) and APM Enterprise is $40/host/month bundled ($47/host/month standalone), adding data streams monitoring and a continuous profiler respectively.

The practical read: if you're evaluating Datadog purely to replace Sentry for error monitoring, you're pricing a full APM contract, not a Sentry-equivalent line item. That's a bad trade for a team that only wants error grouping and alerting. It's a genuinely good trade if you're already running Datadog for infrastructure or APM and paying for hosts anyway - at that point, Error Tracking is functionally free on top of a bill you already carry, and consolidating means one less vendor relationship and one less SDK to maintain. We go deeper on this specific tradeoff, including where Datadog's host-based pricing gets expensive at scale, in our Sentry vs Datadog comparison.

GlitchTip: the actual budget and self-hosting answer

GlitchTip is the option most "Sentry alternatives" posts skip, and it's the one that answers the "I just want this cheaper" question most directly. It's built to be Sentry-SDK-compatible, meaning you can often point an existing Sentry integration at a GlitchTip endpoint without rewriting error capture code. The hosted (cloud) tiers are Free ($0, 1,000 events/month, unlimited projects and team members), Small ($15/month, 100k events/month, support access), Medium ($50/month, 500k events/month, priority email and live chat), and Large ($250/month, 3 million events/month, prioritized development support, with a HIPAA-compliant hosting add-on available). GlitchTip also lists an EU-hosted option in Germany for data-sovereignty requirements, plus a discounted non-profit and open-source rate starting at $5/month.

GlitchTip's pricing page also mentions a self-hosted version, but doesn't publish specifications or a price for it beyond noting it exists - if fully free, self-managed error tracking is the actual goal, confirm the current self-hosting requirements directly with GlitchTip rather than assuming it's zero-effort. For a team that just needs error grouping, alerts, and Sentry-SDK compatibility without Sentry's per-seat pricing model, GlitchTip Small at $15/month for 100k events is the cheapest fixed number on this entire list - cheaper than a single Sentry Team seat, with room for significantly more event volume.

Which one actually fits your reason for leaving Sentry

Reduce this to the actual question you're asking, because "best Sentry alternative" isn't one decision - it's four different decisions wearing the same headline:

• "Sentry got expensive." Try GlitchTip first. $15/month for 100k events undercuts a single Sentry Team seat, and the free self-hosted option removes the bill entirely if you have the ops capacity to run it. Confirm SDK and integration parity for your specific stack before migrating production traffic.
• "We need better support SLAs." Price Bugsnag Preferred or Rollbar Advanced directly against your event volume. Both add dedicated support and SSO options that Sentry reserves for its Business tier and above - but neither publishes a flat number, so this decision requires an actual quote, not a comparison table.
• "We already pay for Datadog." Don't add a second error-tracking bill. Error Tracking rides along with APM at no additional line item, and consolidating vendors is worth more than most teams give it credit for once you count the maintenance cost of a second SDK and a second alerting pipeline.
• "We want data retention past 90 days without an Enterprise contract." Rollbar's Advanced tier publishes 180-day retention as a named feature, which is longer than Sentry Team's 90-day cap without needing a custom Enterprise deal.

The bottom line

There's no single "best" Sentry alternative in this group - there's a best fit for the specific reason you opened this page. Get a real event-volume number from your own account before you compare any of these vendors against Sentry's published tiers, since Bugsnag and Rollbar's actual mid-tier prices only show up once you plug in your usage, and Datadog's number depends entirely on host count rather than error count. Whichever tool you land on, export your existing Sentry alert rules and integration list before you migrate - none of the five vendors above guarantee an automatic one-to-one translation of custom alert logic.
