Error Tracking Tools in 2026: Sentry vs Rollbar vs Bugsnag (SmartBear Insight Hub)

Every application throws errors in production, and the question isn’t whether you’ll need an error-tracking tool but which one actually tells you what broke, how often, and whether it’s getting worse — before a support ticket does. Sentry, Rollbar, and Bugsnag (recently rebranded by its parent company SmartBear as “Insight Hub”) are three of the longest-running names in this category, and in 2026 they’ve diverged more than they’ve converged: one publishes every price on a self-serve page, and two push almost all meaningful plan details behind a sales conversation. We checked each vendor’s current pricing page before writing this comparison.

At a Glance

Tool	Free Tier	Entry Paid Price	Public Self-Serve Pricing?	Best For
Sentry	1 user, 5,000 errors/mo, 30-day retention	Team: $29/mo monthly ($26/mo annual) — unlimited users, 50,000 errors, 90-day retention	Yes — every tier’s dollar price is on the public pricing page	Teams that want transparent, predictable per-tier pricing and self-serve signup
Rollbar	5,000 occurrences/mo, 1,000 sessions, 30-day retention	Essentials: scales 10K–50M occurrences/mo; no public dollar price	No — Essentials and Advanced show no listed price; quote required	Teams that want flexible occurrence-based scaling and are willing to talk to sales for pricing
Bugsnag (SmartBear Insight Hub)	1 user, 7,500 events/mo, 7-day retention	Select: scales 50K–3M events/mo; no public dollar price	No — Select and Preferred both show “starting at $0” with no actual figure	Teams already standardized on SmartBear’s broader testing/observability stack

Short Verdict

Sentry is the only one of the three that lets you see a real price before talking to anyone — its Team and Business tiers are both self-serve with a monthly or annual dollar figure published directly on the pricing page. Rollbar and Bugsnag both gate their paid tiers behind “contact us” once you move past the free plan, publishing only the usage ranges (occurrences, events, replays) rather than what any of it costs. If transparent, no-sales-call pricing matters to you, that alone may decide this comparison before you look at a single feature.

What Each Tool Actually Is

Sentry started as an open-source error tracker and has grown into a broader application-monitoring platform, adding performance tracing, session replay, and — more recently — “Seer,” an AI layer that performs root-cause analysis and can draft a fix for a flagged issue. Every tier includes ownership rules (auto-assigning errors to the engineer whose commit introduced them), suspect-commit detection, and release health tracking; higher tiers add anomaly detection, SAML/SCIM SSO, and a signed BAA for regulated teams.

Rollbar focuses more narrowly on error monitoring itself, with real-time grouping of occurrences into deduplicated items, deploy and version tracking, and — on its higher tiers — Rollbar Analyze, a query layer (RQL) plus a Metrics API for building custom error-trend dashboards. Rollbar’s pricing is structured entirely around monthly “occurrences” (individual error events) and a separate “credits” allowance that scales with plan tier, rather than Sentry’s flatter per-tier error quota.

Bugsnag was acquired by SmartBear and, as of the company’s “Insight Hub” rebrand announcement, is being folded into a broader developer-observability product under that new name — though its dedicated pricing page at the time of writing still displays “Bugsnag” branding without the Insight Hub name attached. Its core differentiators are stability scoring (a single health metric blending crash-free users and sessions) and, on its Preferred tier, “System Metrics” that pull in device-level CPU, memory, and rendering data alongside the error itself — useful specifically for mobile and client-side crash diagnostics.

Sentry’s pricing page is the only one of the three where every number above the free tier is a dollar figure you can act on without a form submission. Rollbar’s and Bugsnag’s pages instead show usage-range sliders (occurrences, events) with no price attached — which makes a true apples-to-apples cost comparison between all three impossible to complete from public information alone; budgeting for Rollbar or Bugsnag at any real scale requires a sales conversation first.

Pros and Cons

Sentry

• Pros: fully transparent self-serve pricing at every tier, broadest feature set (errors + performance tracing + session replay + AI root-cause triage in one product), large ecosystem of SDKs and integrations.
• Cons: Seer’s AI features add extra cost on top of the base plan and were mid-transition to new credit-based pricing at the time of writing; the Developer (free) tier’s 5,000-error cap is tighter than Rollbar’s or Bugsnag’s free-tier equivalents in absolute event count.

Rollbar

• Pros: flexible occurrence-based scaling from 10K to 50M+ per month without changing product tier, Rollbar Analyze gives genuine custom-query access to error trends, a real 14-day full-access trial of the Advanced tier.
• Cons: no public price above the free tier, so budgeting requires sales contact; fewer built-in performance/tracing features than Sentry’s broader platform.

Bugsnag (SmartBear Insight Hub)

• Pros: stability-score health metric is genuinely useful for mobile/client teams, System Metrics (device CPU/memory/rendering) is a differentiator for crash diagnostics, broadest free-tier platform/SDK support (50+ platforms).
• Cons: no public price at any paid tier, shortest free-tier data retention of the three (7 days vs. 30 for Sentry and Rollbar), and the in-progress Insight Hub rebrand means the product’s name and positioning may shift again on short notice.

Who It’s a Good Fit For

Choose Sentry if you want to see a real price today, sign up without a sales call, and get performance tracing and session replay bundled with error tracking rather than bought separately. Choose Rollbar if your error volume is highly variable and you want occurrence-based scaling plus a genuine query layer (RQL) for building custom error-trend reporting, and you’re fine negotiating price directly. Choose Bugsnag/Insight Hub if you need deep mobile or client-side crash diagnostics with device-level telemetry, or you’re already a SmartBear customer for testing tools and want one vendor relationship.

Who Should Look Elsewhere

Teams that need to budget precisely before committing, with no sales call in the process, should be cautious with Rollbar and Bugsnag above the free tier, since neither publishes a self-serve dollar price — Sentry is the only one of the three that fully supports that requirement. Teams needing more than 30 days of error retention on a free plan should skip Bugsnag’s 7-day free tier. And teams that specifically want deep performance tracing alongside error tracking, not just crash/exception monitoring, will find Sentry’s broader platform a better fit than either Rollbar’s or Bugsnag’s narrower error-first focus.

Bottom Line

All three tools do the core job — catching, grouping, and surfacing errors with enough context to fix them — competently. The real differentiator in 2026 isn’t feature depth so much as how each vendor sells: Sentry treats price as something you should be able to see without talking to anyone, while Rollbar and Bugsnag treat it as something to negotiate once you’re past the free tier. If pricing transparency is itself a requirement for your team, that alone makes Sentry the default; if it isn’t, compare the free tiers directly against your actual error volume before starting a sales conversation with the other two.

FAQ

Is Bugsnag now called “SmartBear Insight Hub”? SmartBear announced the Insight Hub rebrand as part of a broader developer-observability push, but as of this writing Bugsnag’s own public pricing page still displays Bugsnag branding without an Insight Hub name change applied — expect the naming to be in transition.

Which tool has the most generous free tier? By raw event/error count, Bugsnag’s free tier (7,500 events/mo) is slightly larger than Sentry’s (5,000 errors/mo) and Rollbar’s (5,000 occurrences/mo), but Bugsnag’s free-tier retention is shortest at 7 days versus 30 days for the other two.

Can I get an exact price for Rollbar or Bugsnag without contacting sales? Not from their public pricing pages as published — both show usage ranges (occurrences or events) for their paid tiers with no dollar amount attached, unlike Sentry, which lists its Team and Business prices directly.

Do any of these tools include AI-assisted fixes? Sentry’s Seer feature performs AI root-cause analysis and can draft a fix, available from the Team tier up at extra cost; the vendor’s pricing page notes new credit-based Seer pricing was rolling out. Rollbar’s and Bugsnag’s public pricing pages do not list a comparable AI-fix feature.
