Sentry alternatives: which to pick in 2026

Sentry alternatives became a real conversation around 2023, and the field has gotten more competitive every year since. Sentry’s pricing model changes pushed teams toward open-source options, and Highlight.io and GlitchTip both matured into credible drop-in replacements. The choice between alternatives comes down to what specifically pushed you off Sentry, not which one has the longest feature list.

I’ve migrated two teams off Sentry in the past year – one to GlitchTip for cost reasons, one to Highlight.io for session replay. Both migrations took less time than budgeted, which is the broader pattern: Sentry’s API has been copied closely enough by the open-source competitors that the switch is usually a few hours of SDK swaps and config changes.

Quick answer: best Sentry alternatives at a glance

Cost is the dominant reason teams leave Sentry, which is why GlitchTip wins by default for migrations. The other options matter when you need features or polish GlitchTip doesn’t have yet.

Why teams look for Sentry alternatives

Three reasons drive most of the searches I see for Sentry alternatives.

The first is pricing. Sentry restructured its plans in 2023 in a way that meaningfully increased costs for teams generating high event volumes. The free tier got tighter, the pricing per event moved up, and teams running consumer-scale applications found themselves on Enterprise quotes that made them re-evaluate. The teams that hit this point typically don’t switch immediately – they look at GlitchTip or self-hosting Sentry first, and migrate only when the bill becomes uncomfortable enough to justify the work.

The second is self-hosting complexity. Sentry’s self-hosted version is functional but heavy: Kafka, Redis, Postgres, ClickHouse, and several worker processes all need to run for a full deployment. Teams that want self-hosted error tracking but can’t justify the operational overhead look for lighter alternatives, which is exactly what GlitchTip and Highlight.io were designed to offer.

The third is feature scope. Sentry has expanded beyond pure error tracking into session replay, performance monitoring, profiling, and crons monitoring. Some teams welcome the breadth; others want a focused error-tracking tool without the surrounding product expansion. The simpler alternatives (Honeybadger, Bugsnag) appeal to teams that want the original Sentry value proposition without the product sprawl.

GlitchTip: the open-source drop-in replacement

GlitchTip is the Sentry alternative most cost-driven migrations land on. The product is open source, API-compatible with Sentry (meaning the official Sentry SDKs work against GlitchTip without code changes), and significantly lighter to self-host than Sentry’s own self-hosted version. The architecture needs only Postgres, Redis, and the GlitchTip app itself, which makes operating it genuinely feasible for most teams.

What makes GlitchTip the right default for Sentry migrations is the migration path itself. You don’t change application code – you change the DSN to point at GlitchTip instead of Sentry, deploy GlitchTip, and you’re done. The team behind it maintains feature parity with Sentry’s error tracking core, though they’ve explicitly chosen not to chase Sentry’s expansion into session replay and the broader product surface.

The trade-off is feature scope. GlitchTip handles error tracking well; it doesn’t include session replay, performance monitoring, or profiling. For teams that only want the error tracking part of Sentry, this is a feature rather than a limitation. For teams that depend on Sentry’s expanded surface, the gap matters.

Bugsnag: the direct commercial alternative

Bugsnag (now part of SmartBear) is the closest commercial competitor to Sentry and has been since both products were young. The feature surface tracks Sentry’s core capabilities: error tracking, stability scores, release tracking, integration with the major CI/CD and notification platforms.

The differentiator Bugsnag emphasizes is stability scoring – they compute a per-release stability score that aggregates error rates against user counts, which is genuinely useful for shipping decisions in production. Sentry has similar metrics now, but Bugsnag’s framing of release stability has been more prominent in the product’s design.

Pricing runs about $59/month for the Plus tier and scales with event volume. Compared to Sentry at equivalent volume, Bugsnag tends to be cheaper but not dramatically so. The choice between them is usually about product feel and specific feature preferences rather than pricing alone.

Pick Bugsnag when you want a polished commercial alternative without leaving for an open-source option, and when stability scoring is a workflow you actually use.

Highlight.io: open source with session replay

Highlight.io is the newer entrant that picked up momentum by combining error tracking with session replay in an open-source package. Teams that wanted both Sentry-style error tracking and FullStory-style session replay without paying for two separate tools found Highlight.io’s bundled approach compelling.

The product is open source with both self-hosted and managed cloud options. The session replay piece is functional and integrates with the error tracking – when an error happens, you can replay the user session leading up to it, which is materially more useful than logs alone for debugging frontend issues. The managed cloud pricing starts around $50/month.

The trade-off is product maturity. Highlight.io is younger than Sentry or Bugsnag, the integration story is less developed in some places, and the community is smaller. For teams willing to be slightly earlier on a tool with strong product fundamentals, the bundled error tracking plus session replay is genuinely useful. For teams that need the most polished workflow, Bugsnag or Sentry itself are safer bets.

Rollbar: the long-standing alternative

Rollbar has been a Sentry alternative since before most current alternatives existed. The product is mature, well-integrated with the major frameworks, and has a track record of reliable error capture across all the major languages and runtimes.

The pitch is steadiness rather than novelty. Rollbar isn’t pushing into new product categories the way Sentry is, and that focus produces a tool that does error tracking well without distractions. For teams that want a reliable commercial competitor to Sentry without the product sprawl, Rollbar is a credible pick.

Pricing starts at $21/month for the Essentials plan and scales by event volume. Compared to Sentry, Rollbar is generally cheaper at equivalent volumes, though the difference narrows on Enterprise tiers. The feature surface is narrower than Sentry’s, which is a feature for teams that want focused error tracking.

Honeybadger: the simple developer-friendly option

Honeybadger is the Sentry alternative for small teams and individual developers who want straightforward error tracking without the complexity of larger platforms. The product handles errors, uptime monitoring, and check-ins (for cron jobs and scheduled tasks) at a single flat per-app price.

What makes Honeybadger work for the small-team segment is the pricing model. Instead of per-event or per-seat pricing that scales aggressively, Honeybadger charges per project, which means costs are predictable as your team or traffic grows. The product is less feature-rich than Sentry or Bugsnag but covers error tracking competently and adds uptime monitoring and cron monitoring at no extra cost.

For solo developers, side projects, and small teams running a handful of applications, Honeybadger’s pricing and simplicity often beat all the alternatives on this list. For larger teams needing deeper analysis or product breadth, the simpler product becomes a constraint rather than a virtue.

Other Sentry alternatives worth knowing

Four other tools come up regularly. Datadog APM and New Relic both include error tracking inside broader observability platforms; pick them when you want unified APM. Raygun combines error tracking with real user monitoring. AppSignal competes with Honeybadger with stronger Ruby and Elixir integration. None has the market share of the main five, but each fits specific situations.

How to pick the right Sentry alternative

The picking question maps to what’s pushing you off Sentry. Cost-driven migrations land on GlitchTip – open source, lighter to self-host than Sentry’s own self-hosted version, API-compatible so the migration is trivial. Teams that want a polished commercial alternative without the open-source operational commitment land on Bugsnag or Rollbar; Bugsnag if release stability scoring is a real workflow, Rollbar if mature simplicity is the goal. Teams that want session replay bundled with error tracking land on Highlight.io.

Small teams and individual developers running a handful of apps land on Honeybadger because the per-project pricing wins on cost predictability. Teams running everything inside a broader APM platform (Datadog, New Relic) often just use that platform’s error tracking instead of adding a separate tool. The question that compresses the choice fastest: name the specific reason Sentry isn’t working, and one of these matches it.

FAQ

If you’ve migrated off Sentry to one of these alternatives and have honest numbers on what changed (cost difference, setup time, feature gaps you didn’t expect), that writeup is worth more than another vendor comparison page. Real migration reports are the gap worth filling.
