Pricing Overview
Sentry uses a freemium pricing model with event-based billing. The Developer tier is free forever for individuals and side projects; paid plans start at $26/month (Team) and $80/month (Business), with Enterprise priced on request. Billing meters four event types separately: errors, performance spans, session replays, and profiling samples. Each plan includes a base allocation across these dimensions, and overages are charged at published per-event rates.
This model is unusually transparent for the observability category. The public pricing page shows base monthly cost, what's included at each tier, and the exact per-event rates above your quota — no vendor-quoted-only walls until you hit Enterprise. The practical implication: teams can forecast their bill with reasonable accuracy by estimating their monthly error rate and replay volume, unlike per-host or per-GB models where usage can balloon unpredictably.
Plan Comparison
| Plan | Price | Users | Errors included | Key features |
|---|---|---|---|---|
| Developer | Free | 1 | 5,000/month | Basic error tracking, 10,000 spans, 50 replays, public GitHub integration |
| Team | $26/month | Unlimited | 50,000/month | Everything in Developer, plus unlimited users, custom alert rules, team management, custom dashboards |
| Business | $80/month | Unlimited | Customizable | Everything in Team, plus advanced insights, code owners, application insights, SSO, custom dashboards, audit log |
| Enterprise | Custom | Unlimited | Negotiated | Dedicated support, SSO SAML, priority SLA, custom contract terms, HIPAA support |
Beyond the base allocations, overages are metered per-event: errors, performance spans, session replays, and profile samples each have published per-unit prices. This means a team on the $26/month Team plan that generates 100,000 errors in a month (double the included quota) pays the base plus the overage rate for the extra 50,000 events. Most teams stay within their included allocation.
Hidden Costs and Considerations
Three cost drivers to watch:
- Event volume spikes during incidents — a release that generates a regression can easily 10x monthly errors. Sentry has inbound filters and sample-rate controls, but teams often don't configure them until after the first bill surprise.
- Session Replay is metered separately from errors — each replay captures ~30 seconds of user interaction plus DOM snapshots. If you enable replay at 100% sample rate on a high-traffic app, replay can become the dominant cost.
- Performance Monitoring spans add up — each traced transaction generates multiple spans (parent + children). A single incoming request might create 20-50 spans. Default sampling is conservative, but teams that bump it to 100% for debugging can blow through their quota.
Annual billing saves ~17% vs monthly. Mid-year plan upgrades are prorated cleanly. Sentry offers non-profit and educational discounts on request.
Cost Estimates by Team Size
These are rough monthly estimates for typical usage patterns:
- Solo developer / hobby project: $0. Developer tier covers everything under normal use.
- Small team (5 engineers, 1 production app): $26/month on the Team plan. Unless you're running a high-traffic consumer app, 50K errors/month is enough.
- Mid-size team (20 engineers, multiple apps): $80-$200/month. Business plan for SSO and dashboards, plus some error-volume overage or a modest Session Replay add-on.
- Large engineering org (100+ engineers, many apps, high traffic): $500-$3,000+/month. Usually a negotiated Enterprise contract with volume discounts across errors, replays, and performance spans.
A practical rule: start on Developer or Team, enable Session Replay only on critical user flows, and set Performance Monitoring sample rate at 0.1 or lower in production until you know what you need. Most teams overspend 2-3x before tuning sample rates.
How Sentry Pricing Compares
Sentry's scoped billing is unusual in observability — most competitors bundle error tracking into a broader APM product:
- Datadog: Free tier plus paid plans starting at $0.75 per host per month (usage-based add-ons extra, including APM and Error Tracking as separate SKUs). Datadog's error tracking is bundled into APM, so you end up paying for both. For error-tracking-only use, Sentry is meaningfully cheaper.
- New Relic: Free tier plus paid plans starting at $19/month per host. New Relic's error tracking is part of APM; a team running 5 production hosts pays $95+/month minimum, versus $26 on Sentry Team.
- Amazon CloudWatch: Pay-as-you-go, $0.01 to $5,120/month on AWS. CloudWatch handles infrastructure and logs well but has no error-grouping feature comparable to Sentry. They're typically used together, not instead of each other.
The honest summary: for the error-tracking-specific job, Sentry is the price-performance leader. For full observability, it's additive to a broader tool like Datadog or Grafana Cloud, not a replacement.
