How much does Sentry cost per month in 2026?

Sentry has four plans in 2026. Developer is free with 5,000 errors, 5M spans, 50 replays, and 5GB logs. Team is 26 dollars per month on annual billing (29 dollars monthly) with 50,000 errors, 5M spans, 50 replays, 5GB logs, and 5GB application metrics. Business is 80 dollars per month on annual billing (89 dollars monthly) with identical base quotas plus SAML, SCIM, advanced quota management, and anomaly detection. Enterprise is custom pricing per the Sentry pricing page as of August 2026.

What is Sentry per-error pricing in 2026?

Sentry bills errors at tiered rates that decrease with volume. On the Team plan, errors above 50K per month cost 0.0003625 dollars each in the 50K-100K tier, dropping to 0.0001500 dollars each in the 20M+ tier. On the Business plan, the same tiers are roughly 2-3x higher per the Sentry pricing documentation. Reserved capacity at 20 percent off the PAYG rate is available for predictable workloads.

How much does Sentry charge per million spans?

Sentry spans are billed per million spans and are the largest line item in most Sentry bills. On the Team plan, spans above 5M per month cost 1.60 to 2.00 dollars per million. On the Business plan, the same volume costs 2.90 to 4.00 dollars per million. A traced app emitting 50M spans per month on Team pays roughly 80 to 100 dollars in span overage fees in addition to the 26 dollar base subscription per BudgetForge's Sentry analysis from July 2026.

What does Sentry Seer AI cost in 2026?

Sentry Seer AI is billed at 40 dollars per active contributor per month, where an active contributor is anyone who makes two or more pull requests to a Seer-enabled repository within a billing cycle. Seer AI is the debugging AI agent that ships with Sentry; it is sold separately from the base plans. As of January 2026, legacy Seer pricing is no longer offered as an add-on to Sentry subscriptions per the Sentry pricing documentation.

Does Sentry charge per seat?

No. Sentry Team, Business, and Enterprise plans all include unlimited users at no additional per-seat cost. The pricing is based on event volume (errors, spans, replays) rather than headcount, which means adding developers to the organization does not increase the base subscription. The only user-based charge is Seer AI at 40 dollars per active contributor per month, which makes Sentry substantially cheaper than per-seat observability tools for large engineering organizations.

What is Sentry Session Replay pricing in 2026?

Sentry Session Replay is included in the base quotas: 50 replays per month on Team and Business plans. Overage rates are roughly 0.00375 dollars per replay above 50, dropping to 0.00245 dollars per replay above 4.5 million replays per month. Session Replay costs the same on both Team and Business plans. For teams that run Session Replay broadly, the overage cost can exceed the base subscription cost per CheckThat's Sentry analysis from June 2026.

What cost-control tactics work best for Sentry?

Three tactics work together. First, enable Spike Protection on all projects; it detects abnormal event surges and automatically drops events to prevent quota consumption during spikes, recalculating thresholds hourly based on the 7-day historical baseline. Second, pre-purchase reserved capacity for predictable monthly volume; reserved capacity is 20 percent off PAYG rates per the Sentry pricing documentation. Third, configure SDK-level sampling rates carefully; trace sampling in particular can cut span volume dramatically.

Q: What is the difference between Sentry Team and Business?

Sentry Team (26 dollars per month annual) and Business (80 dollars per month annual) include identical base quotas: 50,000 errors, 5M spans, 50 replays, and 5GB logs per month. Business adds SAML plus SCIM support, advanced quota management, unlimited custom dashboards, unlimited metric monitors with anomaly detection, and longer sampled retention. Business also charges roughly 2-3x higher per-unit overage rates for errors and spans.

At a glance

Developer: 0 dollars per month, 5K errors, 5M spans, 50 replays, 5GB logs, 1 user per the Sentry 2026 pricing page.

Team annual: 26 dollars per month with 50K errors, 5M spans, 50 replays, 5GB logs, 5GB metrics, unlimited users.

Team monthly: 29 dollars per month with the same quotas as annual.

Business annual: 80 dollars per month with SSO plus SCIM plus anomaly detection, identical base quotas to Team.

Business monthly: 89 dollars per month with the same features as annual.

Seer AI: 40 dollars per active contributor per month, the largest variable cost for AI-forward teams.

Overage is the real bill: a traced app emitting 50M spans per month pays 80 to 100 dollars in span overage on top of the 26 dollar base.

Sentry pricing 2026 error monitoring cost: Developer free 0 dollars with 5K errors, 5M spans, and 50 replays. Team is 26 dollars per month on annual billing (29 dollars monthly) with 50K errors, 5M spans, 50 replays, and 5GB logs. Business is 80 dollars per month on annual billing (89 dollars monthly) with SSO plus advanced features. Sentry bills across five separately-metered categories, so overage, not sticker price, is the real bill for most teams.

Side-by-side pricing comparison

Plan	Price per month	Errors	Spans	Replays	Logs	Users
Developer	0 dollars	5,000	5M	50	5 GB	1
Team annual	26 dollars	50,000	5M	50	5 GB	Unlimited
Team monthly	29 dollars	50,000	5M	50	5 GB	Unlimited
Business annual	80 dollars	50,000	5M	50	5 GB	Unlimited
Business monthly	89 dollars	50,000	5M	50	5 GB	Unlimited
Enterprise	Custom	Custom	Custom	Custom	Custom	Unlimited

The base subscription is a rounding error compared to overage for most production workloads per the Sentry 2026 pricing documentation. The error and span quotas reset monthly, and unused volume does not roll over.

Five separately-metered categories

Sentry bills across five categories that meter independently, and overage, not sticker price, is the real bill. Each category has its own per-tier rate, and a workload that pushes one category over quota pays for that one category only.

Errors: 0.15 to 0.36 dollars per 1,000 errors above 50K on Team; 0.30 to 1.11 dollars per 1,000 on Business per the Sentry pricing documentation.

Tracing spans: 1.60 to 2.00 dollars per million spans above 5M on Team; 2.90 to 4.00 dollars per million on Business. Spans are the largest line item for traced applications.

Session replays: 1.96 to 3.75 dollars per 1,000 replays above 50, the same on both Team and Business plans. Session Replay costs are unpredictable because video replay volume scales with user activity.

Logs and metrics: 0.50 dollars per GB above 5GB on both Team and Business.

Attachments: 0.31 dollars per GB above 1GB on both Team and Business. Cron monitor costs 0.78 dollars each per month above the included 1. Uptime monitor costs 1.00 dollar each per month above the included 1. Continuous profiling costs 0.0315 dollars per hour.

A traced application emitting 50M spans per month pays roughly 80 to 100 dollars in span overage fees in addition to the 26 dollar base per BudgetForge's Sentry analysis from July 2026. The base subscription is a rounding error compared to the overage.

Developer vs Team vs Business vs Enterprise

The four plans map to team size and feature requirements. Choosing the right plan is the single biggest cost lever, because plan-to-plan overage rates differ by 2-3x.

Developer (free): 0 dollars per month with 5,000 errors, 5M spans, 50 replays, 5GB logs, 1 user. Best for solo developers, side projects, and proof-of-concept evaluation. Limited to a single user with no third-party integrations and only email alerts.

Team (26 dollars per month annual, 29 dollars monthly): 50,000 errors, 5M spans, 50 replays, 5GB logs, 5GB metrics, unlimited users, third-party integrations, basic alerting. Best for small teams with predictable low-to-moderate volume.

Business (80 dollars per month annual, 89 dollars monthly): identical base quotas as Team plus SAML plus SCIM support, advanced quota management, unlimited custom dashboards, unlimited metric monitors with anomaly detection, advanced insights. Best for mid-market teams requiring SSO and advanced quota management.

Enterprise (custom): custom pricing with volume discounts, dedicated technical account manager, custom SLAs, advanced security features, and self-hosting options. Best for organizations needing custom contractual terms and dedicated support.

As of January 2026, legacy Seer AI pricing is no longer offered as an add-on to Sentry subscriptions. Seer is now available only via direct purchase. Legacy Seer customers continue on legacy terms per the Sentry pricing documentation.

Error pricing ladder and tracing spans

Errors are billed at tiered rates that decrease with volume. The Team plan PAYG error overage rates are 0.0003625 dollars per error in the 50K-100K tier, dropping to 0.0001500 dollars per error in the 20M+ tier. The Business plan rates are roughly 2-3x higher: 0.0011125 dollars per error in the 50K-100K tier, dropping to 0.0003000 dollars per error in the 20M+ tier. Reserved capacity is 20 percent off PAYG rates for predictable monthly volume per the Sentry pricing documentation.

Spans are priced per million and become the dominant line item for traced apps. A traced app emitting 50M spans per month on the Team plan pays roughly 80 to 100 dollars in span overage fees in addition to the 26 dollar base subscription. The same workload on the Business plan pays 160 to 200 dollars in span overage fees. The per-million-span rate drops with volume; at 500M+ spans per month, the rate is typically 1.60 dollars per million on Team, and at 1B+ spans per month, the rate drops further to roughly 1.50 dollars per million.

Sentry bills spans regardless of whether they include errors. A trace with 50 spans and no errors still costs 50 events. This is why tracing-heavy workloads can quickly exceed error-heavy workloads in Sentry bills. Tracing is opt-in via SDK configuration; for workloads where error visibility is sufficient, disabling tracing cuts the bill by 50 to 70 percent.

Session Replay and Seer AI costs

Session Replay and Seer AI are the two largest variable costs beyond base subscriptions per the CheckThat Sentry analysis from June 2026.

Session Replay overage: 0.00375 dollars per replay above 50, dropping to 0.00245 dollars per replay above 4.5M. A team running 10,000 replays per month pays roughly 0.00375 times 9,950 = 37 dollars per month in replay overage fees. A team running 100,000 replays per month pays 375 dollars per month. Session Replay costs the same on both Team and Business plans.

Seer AI: 40 dollars per active contributor per month, where an active contributor is anyone who makes two or more pull requests to a Seer-enabled repository within a billing cycle. A team with 20 active developers on Seer pays 800 dollars per month in Seer fees. Seer AI is the primary AI cost driver for Sentry customers.

As of January 2026, legacy Seer pricing is no longer offered as an add-on. Seer is now available only via direct purchase. Legacy Seer customers continue on legacy terms per the Sentry pricing documentation.

Real-world TCO scenarios and cost-control tactics

Five common scenarios illustrate how Sentry bills scale. The base subscription is a rounding error in most production scenarios; overage is the bill.

Solo developer: 0 dollars per month, stays under 5K errors, no add-ons.

Small team (5-10 devs): Team plan plus light overages (roughly 75K errors per month). 26 dollars plus roughly 10 dollars overage = 35 to 45 dollars per month.

Scaling startup (20-50 devs): Team plan plus 500K errors plus 10K session replays. 26 dollars plus 90 dollars errors plus 38 dollars replays = 180 to 200 dollars per month.

Mid-market (50-100 devs): Business plan plus Seer AI (10 active contributors) plus 500K errors plus 10K replays. 80 dollars plus 400 dollars Seer plus 138 dollars errors plus 38 dollars replays = 640 to 700 dollars per month.

Enterprise (100+ devs): Custom plan with volume discounts and dedicated support. Typically 2,000 to 5,000+ dollars per month at scale per the CheckThat Sentry analysis from June 2026.

Three cost-control tactics work together. First, enable Spike Protection on all projects; Spike Protection detects abnormal event surges and automatically drops events to prevent quota consumption during spikes, recalculating thresholds hourly based on the 7-day historical baseline per the Sentry pricing documentation. Second, pre-purchase reserved capacity for predictable monthly volume; reserved capacity is 20 percent off PAYG rates. Third, configure SDK-level sampling rates carefully; trace sampling in particular can cut span volume dramatically. The PAYG spending cap is a circuit breaker: when the budget is exhausted, excess data is dropped rather than charged.

How to choose Sentry, Datadog, Honeycomb, and LogRocket

The decision hinges on three variables: error focus, session replay needs, and bundle preference. Sentry is the strongest choice for error-focused monitoring with native session replay. Datadog is the strongest choice if the team needs full-stack observability plus infrastructure plus APM in a single tool. Honeycomb is the strongest choice for event-based tracing analytics with deep query power. LogRocket is the strongest choice if session replay for UX debugging is the primary use case.

For most engineering organizations evaluating error monitoring in 2026, the decision comes down to whether the team already pays for a broader observability platform. If Datadog or New Relic is already in place, layering Sentry on top is duplicative. If the team is starting fresh, Sentry offers the best cost predictability because the per-event pricing model is more transparent than consumption-based observability. Honeycomb is the best choice for teams that prioritise tracing analytics over error monitoring. LogRocket is the best choice for product teams that primarily need session replay for UX debugging.

For enterprise buyers, the three concrete actions are: model the bill on actual error and span volume from the past 90 days rather than the sticker; pre-purchase reserved capacity for predictable workloads (20 percent off PAYG); and audit Session Replay usage before signing, because Session Replay overage can exceed the base subscription cost per the CheckThat Sentry analysis from June 2026.
