How this ranking works
One method for every tool. We compared documented features and published prices; we did not run hands-on tests. Value carries the most weight.
Full methodThis ranking is for development teams choosing an error tracker by what each plan includes and what it costs each month. We compared documented features and published prices for ten services, with prices taken from each vendor's pricing page in US dollars on November 10, 2026. Compare the number of errors or events a plan includes, how long data is kept, how many users can join, and what happens to the bill when a bad release floods the tracker.
The verdict
Sentry gives the most for its $26 Team price: 50k errors, unlimited users, tracing, logs and published overage rates. Honeybadger matches that price and quota and adds uptime monitors and a status page, so it is the better fit for small teams that want one simple bill. GlitchTip costs the least per event, $15 a month for 100k events, and accepts Sentry's SDKs, which makes it the budget pick.

Sentry
8.9/10An application monitoring platform built around error tracking, with tracing, logs, session replay and cron checks in the same account.

Best forDevelopment teams that want the widest error tracking feature set and a quota they can tune event by event.
Sentry is the default reference point for error tracking, and its pricing page explains why it suits growing teams. The free Developer plan gives one user 5k errors a month with email alerts and 10 custom dashboards. Team costs $26 a month on annual billing and raises the allowance to 50k errors, 5GB of logs, 5M tracing spans and 50 session replays, with unlimited users and third-party integrations. Business at $80 a month adds unlimited dashboards, advanced quota management and SAML plus SCIM. Extra errors are billed on a sliding scale that starts at $0.0003625 per error between 50K and 100K and drops to $0.00015 past 20M, and the calculator on the pricing page shows the total before you commit. The trade-off is complexity: errors, logs, spans, replays, cron monitors, uptime monitors and profiling hours each have their own quota, and the Seer AI agent needs its own subscription. Teams that only want error alerts may find a simpler tool easier to budget.
- ✓Team plan allows unlimited users at $26 a month
- ✓Per-error overage rates are published in a pricing calculator
- ✓Covers errors, traces, logs and replays without a second vendor
- ✕Free Developer plan is limited to one user
- ✕The AI debugging agent costs extra on top of the plan
- ✕Many quota types make the bill harder to predict
- Free plan:
- Yes, one user and 5k errors a month
- Team:
- $26 per month billed annually, 50k errors
- Business:
- $80 per month billed annually
- Overage:
- $0.0003625 per error from 50K to 100K
- Users:
- Unlimited on Team and Business
Bottom line: The most complete error tracking platform in this ranking at a $26 entry price. Expect to spend time tuning quotas once traffic grows.

Honeybadger
8.8/10A monitoring service that bundles error tracking, logging, uptime checks, cron monitoring and status pages in one plan.
Price
$26per month
Free Developer plan with 5,000 errors a month; Team $26 per month or $286 per year with 50K errors

Best forSmall teams that want errors, uptime and status pages from one vendor at a flat, predictable price.
Honeybadger prices its Team plan at the same $26 a month as Sentry but packs uptime checks and status pages into the base price. The free Developer plan covers 5,000 errors a month with 15 days of retention, 50 MB a day of log ingest, one uptime monitor and one status page, which is unusually generous for a solo developer. Team at $26 a month, or $286 when paid annually, raises the error quota to 50K, keeps errors for 90 days, adds five uptime monitors and opens the account to unlimited users. Business at $80 a month keeps the same quotas but stretches retention to 180 days and adds compliance features and priority support. Honeybadger also learns each project's usual hourly error rate and alerts when volume is statistically unusual. Its feature list is narrower than Sentry's, with no session replay, and the premium integrations sit behind the paid tiers. For teams that want fewer moving parts, that focus is the appeal.
- ✓Free plan includes uptime monitoring and a status page
- ✓30-day free trial with no credit card required
- ✓Unlimited users on Team
- ✕Free plan keeps error data for only 15 days
- ✕Business costs $80 a month for the same 50K error base
- ✕Premium integrations such as Jira, PagerDuty and SMS are not on every plan
- Free plan:
- Yes, 5,000 errors a month and 15 days retention
- Team:
- $26 per month or $286 per year, 50K errors
- Business:
- $80 per month, 180 days retention
- Uptime monitors:
- 1 on Developer, 5 on Team and Business
- Free trial:
- 30 days, no credit card
Bottom line: The best all-in-one value for small teams, with uptime and status pages included at $26 a month. Pick Sentry instead if you need session replay or deep tracing.

GlitchTip
8.5/10An open source error tracker that accepts Sentry client SDKs, offered as a hosted service or for self-hosting.
Price
$15per month

Best forBudget-conscious teams that want Sentry-compatible error tracking at a low flat price or on their own servers.
GlitchTip is the cheapest way in this ranking to get a usable error quota. Its Small plan costs $15 a month for up to 100k events, twice Sentry's Team quota at a little over half the price, with 90 days of retention, unlimited projects and unlimited team members. Medium adds priority email and live chat support at $50 a month for 500k events, and Large covers 3 million events for $250. Overage is opt-in: turn on on-demand billing and extra events cost $0.17 per 1,000 for the first million, with a monthly spend cap that stops charges once reached. Because GlitchTip accepts Sentry's client SDKs, switching from Sentry mostly means changing a DSN. The code is open source, so teams with strict data rules can run it themselves, and the hosted service has US and EU instances. The limits are depth and polish: there is no session replay, fewer integrations and a smaller feature set, and the free Hobby plan stops at 1,000 events a month.
- ✓Lowest paid entry price in this ranking at $15 a month
- ✓Unlimited projects and team members on paid plans
- ✓Open source code can be run on your own server
- ✕Free Hobby plan allows only 1,000 events a month
- ✕Fewer integrations and analysis features than Sentry
- ✕Priority support starts on the $50 Medium plan
- Free plan:
- Yes, up to 1,000 events a month
- Small:
- $15 per month, up to 100k events
- Medium:
- $50 per month, up to 500k events
- Overage:
- $0.17 per 1,000 events for the first million over
- Self-hosting:
- Yes, open source
Bottom line: The best price per event here, at $15 a month for 100k events. Choose it when budget matters more than advanced analysis.

Airbrake
8.0/10A long-running error and performance monitoring service with tiered plans sized by monthly error volume.
Price
$19per month
From $19 per month for 25,000 errors on monthly billing; $17 per month billed yearly

Best forSmall teams that want a simple error tracker with clearly tiered error quotas.
Airbrake publishes one of the clearest quota ladders in error tracking. Monthly plans start at $19 for 25,000 errors, then step to $59 for 100,000, $129 for 300,000, $299 for 1 million and $799 for 5 million, with yearly billing about 10 percent cheaper. On top of the error volume you pick a plan type: Dev includes one user and one team, Basic opens up unlimited users across three teams, and Pro removes team limits and adds audit features. Every plan has unlimited projects, deploy tracking, advanced search filters and unlimited integrations, and performance monitoring is sold on the same page. Extra errors cost $5.00 per 10K. The catch for teams is that the cheapest prices assume the single-user Dev plan, so a small team should budget for Basic. There is no permanent free tier, and the trial asks for a credit card. Its feature set is solid but lacks the replay and logging breadth of Sentry or Honeybadger.
- ✓Clear published tiers, from $19 for 25,000 errors to $799 for 5 million
- ✓Yearly billing saves about 10 percent
- ✓Unlimited projects even on the Dev plan
- ✕Dev plan allows only one user
- ✕The free trial requires a credit card
- ✕No permanent free plan
- Entry tier:
- $19 per month for 25,000 errors
- Essential tier:
- $59 per month for 100,000 errors
- Growth tier:
- $299 per month for 1 million errors
- On-demand errors:
- $5.00 per 10K
- Users:
- 1 on Dev, unlimited on Basic and Pro
Bottom line: A predictable, no-surprises error tracker with published volume tiers. Teams need the Basic plan for more than one user.

Best forRuby, Elixir and Node.js teams that want errors and performance in one tool priced by requests.
AppSignal is an application performance monitor first, and error tracking is one part of a broader bundle. The free plan covers 30K requests a month with 1GB of logging and 5 days of retention, which suits hobby and side projects. Paid plans are priced by monthly requests rather than error count, so the bill follows traffic, and every plan includes error tracking, performance monitoring with slow query and N+1 detection, host monitoring, anomaly detection, uptime monitoring and dashboards. Long-term log storage and HIPAA compliance are paid add-ons. The pricing page showed euros from our location, so the USD price is marked pending. AppSignal has a strong following in Ruby and Elixir and also supports Node.js, Python, Go, Java, PHP and Rust. For a team that only wants error alerts, the request-based price can be more than a dedicated error tracker, but for teams that also need APM it replaces two tools.
- ✓30-day free trial with no credit card
- ✓Free plan with 30K requests and 1GB of logging
- ✓GDPR and HIPAA compliant, ISO 27001 certified
- ✕Priced by requests, not errors, so error-only teams may overpay
- ✕USD prices did not load for us, so we could not verify them
- ✕Free plan keeps data for only 5 days
- Free plan:
- Yes, 30K requests, 1GB logging, 5-day retention
- Pricing basis:
- Monthly requests
- Free trial:
- 30 days, no credit card
- Add-ons:
- Long-term log storage and HIPAA compliance
Bottom line: A good pick when you want APM and errors from one vendor. Teams that only need error tracking will find cheaper options above.

Best forMobile and web teams that want stability scores and error monitoring across 50+ platforms.
Bugsnag has long been popular with mobile teams, and its pricing reflects that focus on app stability. The free plan covers one user with 7.5K events and 1M performance spans a month across 50+ platforms and 30+ integrations, but data is kept for only 7 days. Paid plans are built from packs: you choose a monthly event volume from 50k up to 3M and a separate span volume for performance monitoring, which captures metrics such as App Start, Screen Loads and Web Vitals. Paid tiers keep data for 60 days and add data forwarding to Splunk and Amazon SQS on higher plans. We could not confirm a USD starting price from the page as it loads for us, so the price is marked pending. Compared with Sentry, Bugsnag is narrower, with no logs or replay in the core plans, but teams shipping iOS and Android apps often prefer its stability-focused view of releases.
- ✓Permanent free tier for solo developers
- ✓Event packs let you choose quota and spans separately
- ✓14-day free trial on paid plans
- ✕Free tier keeps data for only 7 days
- ✕Paid prices only appear after the page's scripts run
- ✕Free plan is limited to one user
- Free plan:
- Yes, 1 user, 7.5K events and 1M spans a month
- Paid event packs:
- 50k to 3M monthly events
- Retention:
- 7 days on Free, 60 days on paid plans
- Free trial:
- 14 days
- Platforms:
- 50+
Bottom line: A strong pick for mobile app stability with a usable free tier. Confirm current USD pricing on the vendor page before buying.

Best forTeams already on Datadog that want errors tied to their existing logs, APM and dashboards.
Datadog sells Error Tracking as one line item on its public price list, which makes it easy to cost. The first 50k errors a month cost $25 on annual billing, $30 month-to-month and $36 on demand, and further errors are priced per thousand: $0.25 per 1k between 50k and 100k, $0.21 up to 500k and $0.17 up to 10 million on annual terms. The product page describes automatic grouping into issues based on stack traces, messages and runtime metadata, alerts for new, recurring and high-volume errors, suspect commits and AI-powered issue classification. The real advantage is context: an error in Datadog sits next to the logs, traces and real user sessions from the same request, so teams that already run Datadog skip a second tool and a second login. For a team that does not use Datadog, the case is weaker. The platform is large, the interface has a learning curve, and there is no free error tier to start with.
- ✓$25 a month for 50k errors on annual billing
- ✓Errors link directly to Datadog logs, traces and RUM
- ✓Per-1k error rates are published for every volume tier
- ✕Best value only if you already pay for other Datadog products
- ✕Month-to-month and on-demand rates are higher
- ✕The Datadog interface takes longer to learn than single-purpose tools
- First 50k errors:
- $25 annual, $30 month-to-month, $36 on-demand
- 50k to 100k errors:
- $0.25 per 1k on annual billing
- 100k to 500k errors:
- $0.21 per 1k on annual billing
- Languages:
- 10+ languages and frameworks
Bottom line: A fair price for teams already invested in Datadog. Teams starting fresh will find Sentry or Honeybadger simpler.

Best forTeams that deploy often and want errors grouped and tied to versions in real time.
Rollbar is a mature error monitoring service with a free plan that covers 5K occurrences and 1K session replays a month, plus a real-time feed, intelligent grouping, stack traces and deploy tracking. Paid plans have moved to a credit model: Essentials adds 4K credits, fine-grained rate limiting and up to 90 days of retention, while Advanced adds 8K credits, adaptive alerts, Rollbar Analyze with RQL queries and a metrics API, SCIM provisioning and up to 180 days of retention. Rollbar also says it protects budgets against surprise bills. We could not read a USD price for the paid plans from the page as fetched, so pricing is marked pending. The credit model makes direct comparison with per-error rivals harder: you need to know how credits map to occurrences and replays for your traffic. Teams that deploy several times a day still like its version tracking and fast grouping.
- ✓Free plan with 5K occurrences and 1K session replays a month
- ✓14-day full access trial
- ✓Advanced plan keeps data for up to 180 days
- ✕Paid plans use a credit system that is harder to compare
- ✕Paid prices did not appear in the page as fetched
- ✕SCIM provisioning only on Advanced
- Free plan:
- Yes, 5K occurrences and 1K sessions a month
- Essentials:
- Includes 4K credits, up to 90 days retention
- Advanced:
- Includes 8K credits, up to 180 days retention
- Free trial:
- 14 days
Bottom line: A capable tracker with a decent free tier and session replay. Check how credits translate to your error volume before upgrading.

Best forTeams with higher error volumes that want unlimited apps and members on every plan.
Raygun splits its platform into Crash Reporting, Real User Monitoring and Application Performance Monitoring, each with its own price. Crash Reporting Basic costs $40 a month on annual billing, or $60 month to month, for 100,000 reserved errors, with additional errors charged on demand at $0.001 each. Team doubles the quota to 200,000 for $80 annually, and Business covers 1,000,000 errors for $400. Every plan includes unlimited apps, members and customer records, attachments, sourcemaps, alerts to email, Slack or Teams, and spike protection that flags unusual volumes before they become a bill. The 14-day trial is the only free option, since Raygun has no permanent free tier. At 100,000 errors the Basic plan is fair, but small teams pay more to start than with Sentry, Honeybadger or GlitchTip, and adding RUM or APM means buying another product from $80 a month annually.
- ✓No user or app limits even on Basic
- ✓Annual billing saves 33 percent
- ✓14-day free trial
- ✕No free plan
- ✕Entry price is higher than Sentry or Honeybadger
- ✕RUM and APM are priced as separate products
- Basic:
- $40 per month annual, $60 monthly, 100,000 errors
- Team:
- $80 per month annual, 200,000 errors
- Business:
- $400 per month annual, 1,000,000 errors
- On-demand errors:
- $0.001 per error
- Free trial:
- 14 days
Bottom line: Solid crash reporting with no seat limits, best for teams that already produce six-figure error counts. Small teams will pay less elsewhere.

Best forFrontend teams that only need JavaScript error tracking and want a simple page-view price.
TrackJS takes a different approach to quotas: you pay by page views rather than errors. Starter costs $49 a month, or $45 a month on yearly billing, for 100K monthly page views, which TrackJS says covers 800,000+ errors with a limit of 20 errors per minute. It includes unlimited users, one application, 10 days of data retention, realtime alerts and an AI Code Debugger. Professional at $99 a month covers 1 million page views, five applications and 15 days of retention, and Business starts at $199. The page-view model protects a frontend team from a bill spike when one bad deploy floods the tracker. The limits are scope and retention: TrackJS only covers JavaScript in the browser and Node.js, so backend teams in other languages need a second tool, there is no free plan, and 10 days of history is short next to the 90 days on Sentry or Honeybadger's Team plans.
- ✓Price is tied to traffic, not error spikes
- ✓Unlimited users from the Starter plan
- ✓Simple setup for JavaScript projects
- ✕JavaScript only, no backend language support beyond Node.js
- ✕Starter keeps data for just 10 days
- ✕No free plan
- Starter:
- $45 per month yearly, $49 monthly
- Page views:
- 100K a month on Starter
- Errors monitored:
- 800,000+ a month on Starter
- Retention:
- 10 days on Starter, 15 on Professional
- Applications:
- 1 on Starter, 5 on Professional
Bottom line: A focused, predictable choice for JavaScript-heavy sites. Full-stack teams get more coverage per dollar from Sentry or Honeybadger.
What to check before you pay
Compare the included quota, not the plan name
Entry plans differ widely in what they cover. Sentry Team and Honeybadger Team include 50k errors for $26, Datadog includes 50k errors for $25 on annual billing, Airbrake covers 25,000 errors for $19, GlitchTip 100k events for $15 and Raygun 100,000 errors for $40.
Know what happens past the limit
A bad deploy can multiply error volume in minutes. Sentry and Datadog publish per-error overage rates, GlitchTip lets you set a monthly spend cap on on-demand events, Raygun charges $0.001 per extra error and TrackJS prices by page views so error floods do not change the bill.
Check retention and seats
Free plans keep data briefly: 7 days on Bugsnag Free, 5 days on AppSignal's free plan and 15 days on Honeybadger Developer. Several free and entry plans are limited to one user, including Sentry Developer, Bugsnag Free and Airbrake Dev.
Decide how much else you need
Some tools stop at errors, others bundle more. Honeybadger includes uptime monitors and status pages, Sentry adds tracing, logs and replay, AppSignal is a full APM priced by requests, and Datadog makes most sense if you already use its logs and traces.
FAQ
What is the best free error monitoring tool?
Sentry and Honeybadger both give 5,000 errors a month on their free plans; Sentry limits it to one user, while Honeybadger adds an uptime monitor and status page. Bugsnag's free plan covers 7.5K events for one user, and Rollbar's covers 5K occurrences plus 1K session replays.
What is the cheapest paid error tracking plan?
GlitchTip's Small plan costs $15 a month for up to 100k events. Airbrake starts at $19 a month for 25,000 errors, and Datadog Error Tracking costs $25 a month on annual billing for the first 50k errors.
How many errors does a small team need?
Many small teams fit within 50k errors a month, the quota on Sentry Team, Honeybadger Team and Datadog's first tier. Busy apps or noisy frontends can exceed that quickly, so check each tool's overage rate or spend cap before you choose.
Can I switch from Sentry without changing my code?
GlitchTip says it works with Sentry's open source client SDKs, so moving usually means pointing your existing SDK at a new DSN. Other tools in this list use their own SDKs.
How did we rank these tools?
We compared documented features and published prices, then scored each tool on value, features and ease of use, weighted 40, 35 and 25. Prices we could not confirm in USD are marked pending and score more conservatively on value.
