Why Teams Look for Sentry Alternatives in 2026
Sentry is the default answer to "how do we find out when production breaks?" It has SDKs for almost every language, a generous free tier, and a product that now covers errors, tracing, session replay, logs, cron and uptime monitors, and an AI debugging agent called Seer. For a lot of teams there is no reason to leave.
The reasons people do look around tend to be specific:
- The bill grows by data category, not by seat. Sentry meters errors, spans, replays, logs, attachments and monitors separately. That is fair, but it means a noisy release or a new replay rollout can move the bill in ways that are hard to predict.
- Data is dropped when the budget runs out. Sentry's docs say that once you exhaust your reserved volume and pay-as-you-go budget, further data is dropped (and not charged). You stay within budget, but you lose visibility for the rest of the month.
- Self-hosting is heavier than people expect. Self-hosted Sentry is free to run, but the documented minimum is 4 CPU cores and 16 GB of RAM plus 16 GB of swap, and it comes without dedicated support.
- License. Sentry is "Fair Source" under the Functional Source License (FSL). Each release converts to Apache 2.0 after two years, but until then you cannot offer it as a competing service. For most companies this does not matter; for some legal teams it does.
- Consolidation. Teams already paying for Datadog often ask whether they need a second tool just for exceptions.
This guide compares Sentry with six alternatives: Rollbar, BugSnag, Datadog Error Tracking, Honeybadger, Raygun and GlitchTip. The focus is on what you actually pay for (errors, events, occurrences, spans, replays, sessions), whether you can self-host, and how wide each SDK library is. All prices below were checked on each vendor's pricing page in October 2026.
How Pricing Units Differ (Read This Before Comparing Prices)
The headline numbers above are not directly comparable because each vendor counts something different.
- Sentry bills each data category on its own: errors, spans (tracing), replays, attachments (GB), logs (GB), application metrics (GB), cron monitors and uptime monitors. Paid plans include 50K errors, 5M spans and 50 replays, and you buy more as reserved volume (cheaper, prepaid) or through a pay-as-you-go budget.
- Rollbar bills by occurrences, meaning each error event received. Session replay and AI credits are separate add-ons with their own price tables.
- BugSnag bills by events (an unhandled exception, or a handled exception you choose to report) and spans for performance monitoring, chosen as separate tiers.
- Datadog bills Error Tracking per 1,000 errors in volume tiers. APM is billed per host and RUM per 1,000 sessions, so a full Datadog setup has several meters.
- Honeybadger bills by errors per month on a flat plan, plus a daily allowance for Insights (logs and events) data.
- Raygun bills each product separately: Crash Reporting by errors, Real User Monitoring by sessions, APM by traces.
- GlitchTip uses one event pool that covers error occurrences, uptime checks, performance transactions and megabytes of release files.
The practical takeaway: if you only need exceptions, compare cost per 100K errors. If you want tracing and replay too, Sentry and Datadog are the only tools here that put all of them in front of you, and you should model each meter separately.
Detailed Tool Reviews
1. Sentry: The Benchmark
What it is: Application monitoring centered on errors, with tracing, session replay, profiling, logs, cron and uptime monitoring, and the Seer AI agent.
Pricing (checked October 2026):
- Developer (free): 5K errors, 5M spans, 50 replays, 1 GB attachments, 1 cron monitor, 1 user, 30-day lookback.
- Team: $26/month billed annually or $29 month to month. 50K errors, 5M spans, 50 replays, unlimited users, up to 90-day lookback.
- Business: $80/month billed annually or $89 month to month. Same included volumes as Team, plus Business features such as SAML and SCIM, and additional sampled retention.
- Enterprise: custom.
Extra volume is metered per category. On Team, reserved errors between 50K and 100K cost $0.00029 each (about $0.29 per 1,000), falling to $0.00012 each above 20M. Spans above 5M cost $0.0000016 each reserved on Team (about $1.60 per million). Replays above 50 cost $0.003 each. Logs and application metrics include 5 GB each, then $0.50/GB on pay-as-you-go. Cron monitors are $0.78 each and uptime monitors $1.00 each. Seer is a separate charge of $40 per active contributor per month, where an active contributor is someone who opens 2 or more pull requests in a Seer-enabled repository.
SDK coverage: The broadest in this list. Official SDKs cover .NET, Android, Apple platforms, Dart/Flutter, Elixir, Go, Java, JavaScript (React, Vue, Angular, Next.js, Svelte, Nuxt, Remix, Node), Kotlin, native C/C++, PHP, Python, React Native, Ruby, Rust and PowerShell, plus game engines including Unity, Unreal, Godot and console platforms.
Self-hosting: Free, licensed under the FSL (converting to Apache 2.0 after two years). The documented minimum is 4 CPU cores, 16 GB RAM plus 16 GB swap (or 32 GB RAM) and 20 GB of disk. Spike protection, spend allocation and Seer are not available self-hosted, and support is community-only.
Choose Sentry if: you want one tool for errors, traces and replays across many languages, and you are willing to manage quotas per category.
Skip it if: you only need exception alerts and want a single, predictable number on the invoice.
2. Rollbar: The Most Transparent Error-Only Pricing
What it is: A focused error monitoring service with grouping, deploy tracking, session replay and AI features. Rollbar publishes every price step on a machine-readable pricing page, which makes budgeting simple.
Pricing (checked October 2026):
- Free: 5K occurrences/month, 1K session replays/month, 30-day retention, unlimited users.
- Essentials: from $9/month (or $7.50/month billed annually) at 10K occurrences. 50K occurrences costs $29/month ($24.17 annual); 100K costs $49/month ($40.83 annual); 1M costs $199/month ($165.83 annual). 90-day retention and 4,000 AI credits/month.
- Advanced: from $13/month ($10.83 annual) at 10K occurrences; 50K costs $79/month ($65.83 annual). 180-day retention, adaptive alerts, SCIM, 8,000 AI credits/month, and the Rollbar Analyze query and metrics API included.
- Enterprise: custom, for over 80M events/month, with custom retention and a HIPAA BAA.
Annual billing works out to two months free. Rollbar does not charge per seat on any plan. Session replay beyond the free 1K is an add-on (for example, 10K replays is $26/month on Essentials).
Overage: You pick one of three behaviors. The default is a hard cap that stops processing new events until the next cycle. You can instead turn on on-demand events at your plan's normal per-event rate (no ceiling), or set a dollar-capped overage budget.
SDK coverage: Server, browser and mobile SDKs for the mainstream languages, plus a REST API and a Terraform provider. Coverage is good for web and backend stacks but narrower than Sentry's for game engines and niche platforms.
Self-hosting: None is listed on Rollbar's pricing; it is a hosted service.
Choose Rollbar if: you want error monitoring with a published price for every volume tier and no seat costs.
Skip it if: you need distributed tracing in the same tool, or you must keep data on your own servers.
3. BugSnag (SmartBear): Best for Mobile Stability
What it is: Error and performance monitoring owned by SmartBear. SmartBear has also marketed it under the Insight Hub name, but bugsnag.com, the documentation and the app currently use the BugSnag brand. BugSnag is known for mobile features: stability scores, symbolicated crashes (dSYMs, ProGuard, source maps), breadcrumbs and release health.
Pricing (checked October 2026):
- Free: 1 user, 7.5K events and 1M spans per month, 7-day retention.
- Select: unlimited users, events from 50K to 3M/month and spans from 1M to 150M/month, 60-day retention, end-to-end diagnostics and basic notifications.
- Preferred: events from 100K to 3M/month and spans up to 300M/month, adding automatic error prioritization, stability benchmarks, advanced segmentation, SAML SSO and system metrics.
- Enterprise: custom, adding premium support, automatic user provisioning, feature flag and experiment tracking, and a choice of on-premises or SaaS deployment.
The pricing page computes Select and Preferred prices from the event and span tiers you choose, with monthly and yearly billing. We could not confirm a fixed dollar figure from the page, so use BugSnag's calculator for your volumes.
SDK coverage: BugSnag says it supports 50+ platforms across mobile, web, desktop and server, with particular depth on iOS, Android, React Native, Flutter and Unity.
Self-hosting: Only through the Enterprise on-premises option.
Choose BugSnag if: you ship mobile apps and care about crash-free session rates and release stability more than backend tracing.
Skip it if: you need a free plan for a team (the free tier is one user) or published prices without a calculator.
4. Datadog Error Tracking: Best If Datadog Is Already Your Platform
What it is: Datadog's Error Tracking groups errors from APM traces, Real User Monitoring (browser and mobile) and logs into issues. It can also run without APM: you can instrument with Datadog's browser or mobile SDKs, or send errors through logs.
Pricing (checked October 2026): Error Tracking is priced in volume tiers per month:
- Up to 50K errors: $25/month billed annually, $30 month to month, $36 on demand.
- 50K to 100K: $0.25 per 1,000 errors (annual).
- 100K to 500K: $0.21 per 1,000.
- 500K to 10M: $0.17 per 1,000.
- 10M to 20M: $0.12 per 1,000.
- Over 20M: $0.10 per 1,000.
The related products have their own meters: APM starts at $31 per host per month (annual), RUM Measure is $0.15 per 1,000 sessions, and the Session Replay add-on is $2.50 per 1,000 sessions (annual). To control cost, Error Tracking supports daily rate limits on billable errors, inclusion and exclusion rules, and dynamic sampling that kicks in during spikes.
Sentry SDK compatibility: Datadog documents a migration path that points existing Sentry SDKs at a Datadog DSN. It lists verified versions for JavaScript, Python, Java, .NET, Go and Ruby. Only error events and messages are accepted (they appear as logs); traces, attachments and sessions are not. It requires Error Tracking for Logs, and Datadog recommends its own SDKs for the full feature set.
Self-hosting: No. Datadog is a hosted service.
Choose Datadog if: you already pay for Datadog APM, RUM or logs and want exceptions next to your traces, metrics and dashboards.
Skip it if: errors are all you need. Datadog's error pricing is competitive, but the value comes from the rest of the platform, and its multi-meter billing is the most complex here.
5. Honeybadger: One Flat Bill for Small Teams
What it is: Error monitoring bundled with uptime monitoring, cron and scheduled job check-ins, status pages, deploy tracking, and Insights (logs, events and dashboards). Its Ruby and Elixir support is particularly deep.
Pricing (checked October 2026):
- Developer (free): 5K errors/month, 15-day error retention, 1 user, 1 uptime monitor, 1 status page, Insights at 50 MB/day with 7-day retention.
- Team: $26/month or $286/year. 50K errors/month, 90-day retention, unlimited users and projects, 5 uptime monitors, Insights at 100 MB/day kept 7 days by default (up to 30 days with a larger logging add-on). Overage is $0.0003 per error notice over quota.
- Business: $80/month or $880/year. 50K errors/month, 180-day retention, unlimited teams, more dashboards and alarms, Insights kept 14 days by default (up to 60 days with a larger logging add-on). Overage is $0.0006 per error notice over quota.
SDK coverage: Ruby, JavaScript, PHP, Python, Elixir, Go, Java, .NET/C#, Crystal and Clojure, plus native mobile support through a Cocoa SDK (iOS and macOS) and a React Native guide. Strongest on Ruby and Elixir; Sentry and BugSnag cover more mobile platforms and game engines.
Self-hosting: No.
Choose Honeybadger if: you are a small team that wants errors, uptime checks and cron monitoring without stitching together three tools.
Skip it if: you need session replay or deep distributed tracing, or your error volume is well above 50K a month (overage adds up at those per-error rates).
6. Raygun: More Errors per Dollar, No Free Plan
What it is: Three products sold separately: Crash Reporting, Real User Monitoring (RUM) and APM. It has a long history with .NET teams.
Pricing (checked October 2026), Crash Reporting:
- Basic: $40/month billed annually ($60 monthly) for 100K errors.
- Team: $80/month annually ($120 monthly) for 200K errors.
- Business: $400/month annually ($600 monthly) for 1M errors.
- Enterprise: custom.
All tiers include unlimited apps and team members and 180-day retention. On-demand overage is $0.001 per error. RUM starts at $80/month annually for 100K sessions and APM at $80/month annually for 100K traces. Every plan starts with a 14-day trial; there is no free tier.
SDK coverage: Crash Reporting covers Android, Apple, browser JavaScript, C++, ColdFusion, Elixir, Flutter, Go, .NET, Java, Node.js, PHP, PowerShell, Python, React Native, Ruby, Unity and Xamarin, among others. APM is much narrower: .NET, Node.js and Ruby.
Self-hosting: No.
Choose Raygun if: you send a lot of errors (100K+ a month) and want a fixed monthly tier, especially on .NET.
Skip it if: you want a free plan, or APM for Python, Java or Go.
7. GlitchTip: Open Source and Sentry-SDK Compatible
What it is: An open-source error tracker that accepts events from Sentry's client SDKs. It covers error tracking (exceptions, log messages, CSP violations), basic performance monitoring, uptime monitoring and logs. There is no session replay.
Pricing (hosted, checked October 2026):
- Free: up to 1K events/month, unlimited projects and team members.
- Small: $15/month for up to 100K events.
- Medium: $50/month for up to 500K events, with priority email and chat support.
- Large: $250/month for up to 3M events, with development support; a BAA is available, and HIPAA compliance is an add-on.
An "event" covers error occurrences, uptime checks, performance transactions and each megabyte of release files, so uptime checks draw from the same pool as errors. EU hosting in Germany is available on all plans, and nonprofit and open-source discounts start at $5/month.
SDK coverage: Whatever Sentry's SDKs cover for errors, since you point a Sentry DSN at GlitchTip instead. Sentry-only features (replay, profiling, Seer) do not carry over.
Self-hosting: Free under the MIT license. The documented requirements are modest: 512 MB RAM recommended (256 MB minimum for the all-in-one setup), PostgreSQL 14+, and optional Valkey or Redis. GlitchTip estimates about 30 GB of disk for an instance handling 1M events a month. That is a fraction of self-hosted Sentry's footprint.
Choose GlitchTip if: you want to self-host error tracking cheaply, need a permissive open-source license, or want to keep your existing Sentry instrumentation while cutting cost.
Skip it if: you depend on Sentry's replay, profiling or AI features, or want a large vendor with enterprise support.
Self-Hosting Compared
| Tool | Self-Hosted Option | License | Documented Minimum |
|---|---|---|---|
| Sentry | Yes, free | FSL (Apache 2.0 after 2 years) | 4 CPU, 16 GB RAM + 16 GB swap, 20 GB disk |
| GlitchTip | Yes, free | MIT | 512 MB RAM recommended, PostgreSQL 14+ |
| BugSnag | Enterprise on-premises | Commercial | Through sales |
| Rollbar, Datadog, Honeybadger, Raygun | No | Commercial SaaS | Not applicable |
If data residency is the only reason you want to self-host, check hosted regions first: GlitchTip, for example, offers EU hosting in Germany on every hosted plan.
What 100K Errors a Month Costs
A rough comparison for a team sending about 100K errors per month, error tracking only, annual billing where offered:
- Sentry Team: $26 base (50K errors) plus about 50K extra errors at $0.00029 each reserved, roughly $14.50, so about $40/month.
- Rollbar Essentials: $40.83/month at the 100K tier.
- Datadog Error Tracking: $25 for the first 50K plus 50K at $0.25 per 1,000 ($12.50), about $37.50/month.
- Honeybadger Team: $23.83 ($286/year) plus 50K over quota at $0.0003 each ($15), about $38.83/month.
- Raygun Basic: $40/month for 100K errors.
- GlitchTip Small (hosted): $15/month for 100K events.
- BugSnag: priced by calculator.
At this volume the commercial tools land within a few dollars of each other. The real differences are in what else is included (tracing, replay, uptime), retention, and what happens when you hit the limit.
How to Choose
- List your meters. Errors only? Errors plus traces? Replays? Each vendor bills these differently, so estimate monthly volumes before comparing.
- Decide what happens at the limit. Sentry drops data after reserved volume and budget are used. Rollbar lets you pick hard cap, on-demand or a capped budget. Datadog uses daily rate limits and sampling. Know which behavior you want before an incident.
- Check SDK coverage for your stack. Sentry covers the most platforms. If you use game engines or less common languages, confirm the alternative has an official SDK.
- Weigh self-hosting honestly. Self-hosted Sentry is a real infrastructure commitment. GlitchTip is much lighter but has fewer features.
- Consider migration cost. GlitchTip and Datadog both accept Sentry SDK events, which makes trying them a configuration change rather than a re-instrumentation project.
Final Recommendations
- Most teams should stay on Sentry if they use tracing or replay. Set reserved volumes and a pay-as-you-go budget deliberately, and use filters and sampling to keep noise out.
- Pick Rollbar if you want error monitoring only, with published prices and a hard cap by default.
- Pick BugSnag for mobile-first products that live and die by crash-free rates.
- Pick Datadog Error Tracking if Datadog is already your observability platform.
- Pick Honeybadger if you are a small team and want errors, uptime and cron checks on one flat plan.
- Pick Raygun if you have high error volumes, especially in .NET, and do not need a free tier.
- Pick GlitchTip if you want open source, cheap hosting, or a low-maintenance self-hosted install that keeps your Sentry SDKs.
