Direct answer: error tracking in 2026 is “base fee + usage overage”, but the thresholds differ: Sentry Team 26/month (annual) includes 50k errors; overage 50k–100k at 0.0003625/error (0.3625/1k), 100k–500k at 0.0002188 (0.2188/1k), 500k–10M at 0.0001875 (0.1875/1k); Datadog Error Tracking is a flat 25/month (annual, 36 on-demand) below 50k, then 0.25/1k for 50k–100k, 0.21/1k for 100k–500k, 0.17/1k for 500k–10M. At 50k/100k/500k/1M/10M errors: Sentry 26/44.13/131.65/225.40/1,912.90; Datadog 25/37.50/121.50/206.50/1,736.50. Bottom line: the two are almost the same at low volume; Datadog is about 10% lower at high volume; but Datadog’s Error Tracking is already included for APM/RUM errors, so if you already pay for Datadog APM/RUM the incremental cost may be 0; Sentry is standalone error tracking with logs/traces/replays included.
This guide is for teams responsible for application stability, frontend/backend errors, SRE and procurement. Data cut-off: 7 November 2026; prices come from Sentry Pricing and Datadog Pricing, in USD, excluding tax; all TCOs are editorial calculations, not vendor quotes. “Error/log/span/replay, 50k threshold, APM/RUM inclusion” differ, so official facts, editorial assumptions and non-comparable items are kept separate.
Sentry Team 26/month includes 50k errors; overage 0.3625/1k (50k–100k), 0.2188/1k (100k–500k), 0.1875/1k (500k–10M); Business 80/month. Datadog Error Tracking flat 25/month (annual), 36 on-demand below 50k; 0.25/1k (50k–100k), 0.21/1k (100k–500k), 0.17/1k (500k–10M). 50k/100k/500k/1M/10M: Sentry 26/44.13/131.65/225.40/1,912.90; Datadog 25/37.50/121.50/206.50/1,736.50. Datadog APM/RUM errors are included — incremental may be 0.
Two meters: 50k-error tier + usage vs flat below 50k + usage
Sentry: Developer free (5k errors, one user); Team 26/month (annual) includes 50k errors, unlimited users, 20 dashboards, 5GB logs, 5M spans, 50 replays, 1 uptime/cron monitor; Business 80/month (annual) adds more dashboards/advanced quota/SAML+SCIM; Enterprise custom. Team overage: 50k–100k 0.0003625/error (0.3625/1k), 100k–500k 0.0002188 (0.2188/1k), 500k–10M 0.0001875 (0.1875/1k), 10M–20M 0.0001625, 20M+ 0.00015. Datadog Error Tracking: below 50k errors, flat 25/month (annual) or 36 on-demand; above 50k, 0.25/1k (50k–100k annual), 0.21/1k (100k–500k), 0.17/1k (500k–10M), 0.12/1k (10M–20M), 0.10/1k (20M+); monthly/on-demand rates are higher. Datadog’s Error Tracking is included for errors collected as part of APM traces and RUM sessions; standalone frontend/backend/log errors are billed as above.
| Platform/tier | Base monthly | Errors included | Overage (annual) | Boundary |
|---|---|---|---|---|
| Sentry Developer | 0 | 5k | — | One user |
| Sentry Team | 26 (annual) | 50k | 0.3625/1k (50k–100k) | Unlimited users/5GB logs/5M spans/50 replays |
| Sentry Business | 80 (annual) | 50k | Same | SAML+SCIM/advanced quota |
| Datadog Error Tracking | 25 (<50k, annual) | 50k | 0.25/1k (50k–100k) | APM/RUM errors included |
| Datadog on-demand | 36 (<50k) | 50k | 0.38/1k (50k–100k) | Higher on-demand/monthly |
Sources: Sentry Pricing and Datadog Pricing (US/USD, accessed 7 November 2026). Excludes tax, commitments/annual billing, logs/spans/replays/uptime/cron overage, APM/RUM/Infra, support/compliance and migration; Sentry rates are tiered by error range; whether Datadog’s <50k flat stacks with >50k usage follows the page wording; this article estimates “25 base + overage”.
TCO: 50k/100k/500k/1M/10M errors
By errors/month: 50k Sentry 26, Datadog 25; 100k Sentry 26+50×0.3625=44.13, Datadog 25+50×0.25=37.50; 500k Sentry 26+18.125+400×0.2188=131.65, Datadog 25+12.5+400×0.21=121.50; 1M Sentry +500×0.1875=225.40, Datadog +500×0.17=206.50; 10M Sentry +9,500×0.1875=1,912.90, Datadog +9,500×0.17=1,736.50. The two are almost the same at low volume; Datadog is about 10% lower at high volume, but the gap is small — platform inclusion (APM/RUM errors already covered) is the decisive factor.
| Monthly errors | Sentry Team | Datadog Error Tracking | Lower |
|---|---|---|---|
| 50k | 26.00 | 25.00 | Datadog (small gap) |
| 100k | 44.13 | 37.50 | Datadog |
| 500k | 131.65 | 121.50 | Datadog |
| 1M | 225.40 | 206.50 | Datadog |
| 10M | 1,912.90 | 1,736.50 | Datadog |
Editorial calculation, not a quote. Sentry Team 26 includes 50k, overage at 0.3625/0.2188/0.1875 per 1k; Datadog 25 includes 50k, overage at 0.25/0.21/0.17 per 1k (annual). Excludes tax, logs/spans/replays/uptime/cron, APM/RUM/Infra, support and migration; Datadog APM/RUM errors are included, so the actual increment may be 0.
Effective unit cost: real cost per 1k errors
Amortize the monthly fee per 1k errors: 50k Sentry 0.520, Datadog 0.500; 100k 0.441 vs 0.375; 500k 0.263 vs 0.243; 1M 0.225 vs 0.207; 10M 0.191 vs 0.174. Both effective rates fall with volume; Datadog is always slightly lower. But Sentry’s 26 also includes unlimited users/5GB logs/5M spans/50 replays, while Datadog Error Tracking is errors only — logs/APM/RUM are extra (unless already purchased). So “per 1k errors” is not the only metric; add the platform scope back.
| Monthly errors | Sentry effective $/1k | Datadog effective $/1k | Gap |
|---|---|---|---|
| 50k | 0.520 | 0.500 | +0.020 |
| 100k | 0.441 | 0.375 | +0.066 |
| 500k | 0.263 | 0.243 | +0.020 |
| 1M | 0.225 | 0.207 | +0.018 |
| 10M | 0.191 | 0.174 | +0.017 |
Editorial conversion, not a quote. Effective rate = monthly fee/errors×1,000; Sentry includes 50k + tiered overage; Datadog 25 base + tiered overage (annual). Excludes tax, logs/spans/replays, APM/RUM/Infra, support and migration; platform scope differs, so do not compare effective rates alone.
Platform scope: Sentry standalone vs Datadog included
Sentry is standalone error tracking: Team 26 includes errors, 5GB logs, 5M spans, 50 replays, 1 uptime/cron, fitting teams that “only want error tracking”. Datadog’s Error Tracking is included for APM/RUM errors at no extra cost; standalone frontend/backend/log errors are billed at 25/36 or usage. If you already pay for Datadog APM (31/host) or RUM (0.15/1k sessions), the error-tracking increment may be 0; if you do not, standalone Error Tracking from 25 is also cheap. Sentry’s advantage is standalone, cross-language SDK/issue workflow/replay/log bundle; Datadog’s is the same platform as APM/RUM/logs and error-to-trace correlation.
| Item | Sentry Team | Datadog Error Tracking |
|---|---|---|
| Positioning | Standalone error tracking | Part of APM/RUM/log platform |
| Below 50k | 26 (includes 50k) | 25 (annual)/36 on-demand |
| APM/RUM errors | Billed per error | Included, no extra |
| Logs/traces/replays | 5GB/5M spans/50 replays | Buy Log/APM/RUM separately |
| Users | Unlimited | Per Datadog platform |
| Typical use | Standalone/cross-language | Already on Datadog APM/RUM |
Sources: the two official pricing pages (accessed 7 November 2026). This is a public pricing/inclusion overview; SDK/language coverage, issue workflow, retention, sampling, SSO/audit and support depend on tier/contract.
Which option fits which scenario?
Only error tracking, cross-language/standalone, want logs/traces/replays bundled: Sentry Team 26; need SSO/SCIM/advanced quota: Sentry Business 80; already on Datadog APM/RUM, want error-to-trace correlation: Datadog Error Tracking (increment may be 0); using Datadog without APM/RUM: standalone Error Tracking from 25; very high error volume (10M+): Datadog’s effective rate is slightly lower, but the gap is small — choose by platform; very low volume/single user: Sentry Developer free 5k. Do not compare only “per 1k errors”; include whether APM/RUM/logs are already included.
| Scenario | First choice | Monthly (example) | Check first |
|---|---|---|---|
| Standalone/cross-language | Sentry Team | 26 (50k) | SDK/issue workflow |
| SSO/SCIM/advanced quota | Sentry Business | 80 (50k) | Compliance/audit |
| Already on Datadog APM/RUM | Datadog Error Tracking | 0 increment (APM/RUM included) | Error source/sampling |
| Datadog without APM/RUM | Datadog Error Tracking | 25 (50k) | Logs/traces included? |
| 10M+ errors | Effective rate + platform | 1,736.50 vs 1,912.90 | Tiers/contract |
| Single user/very low volume | Sentry Developer | 0 (5k) | One user |
Sources: the two official pricing pages (accessed 7 November 2026). This is an editorial decision matrix, not vendor advice; SDK coverage, error grouping, sampling, retention, SLA and migration cost were not tested.
What should procurement and acceptance specify?
At least ten things: monthly errors/peaks, projects/languages, logs/traces/replay needs, retention, sampling/quota, whether APM/RUM is already purchased, SSO/audit, alerting/workflow, SLA/support, contract. Run a 2–4 week POC on real errors and record errors, grouping, sampling, retention, alerting and the bill; do not compare only “50k tier 26/25”.
- Errors: monthly total/peaks, projects/environments, duplicates/noise.
- Language/SDK: frontend/backend/mobile, frameworks, symbolication.
- Logs/traces/replay: needed or not, volume, retention.
- Sampling/quota: error sampling, quota management, overage.
- APM/RUM: already purchased, errors included?.
- Alerting/workflow: routing, silence, issue state.
- SSO/audit: SAML/SCIM, audit logs.
- Retention: 30/90/180 days, export.
- SLA/support: uptime, response, credits.
- Contract: annual/monthly, commitment, renewal, exit.
FAQ
Which is cheaper?
50k: Sentry 26, Datadog 25; 100k: 44.13 vs 37.50; 500k: 131.65 vs 121.50; 1M: 225.40 vs 206.50; 10M: 1,912.90 vs 1,736.50. Datadog is slightly lower, but the gap is small; if you already use Datadog APM/RUM, the error-tracking increment may be 0.
What does Sentry Team 26 include?
50k errors, unlimited users, 20 dashboards, 5GB logs, 5M spans, 50 replays, 1 uptime/cron monitor; Business 80 adds more dashboards/advanced quota/SAML+SCIM.
What is the difference between Datadog 25 and 36?
25 is the annual <50k flat; 36 is on-demand. Above 50k, 0.25/0.21/0.17 per 1k (annual); APM/RUM errors are included at no extra cost.
Why may Datadog’s increment be 0?
Datadog Error Tracking is included for APM traces/RUM sessions; if you already buy APM (31/host) or RUM (0.15/1k sessions), error tracking is not separately charged. Standalone frontend/backend/log errors are billed at 25/usage.
How does Sentry’s overage work?
Team 50k–100k 0.0003625/error (0.3625/1k), 100k–500k 0.0002188, 500k–10M 0.0001875, 10M–20M 0.0001625, 20M+ 0.00015; tiered.
Who wins at 10M errors?
Sentry 1,912.90, Datadog 1,736.50 (annual); Datadog about 9% lower. If already on Datadog APM/RUM, the increment is lower; if you only want standalone error tracking, Sentry’s bundle/workflow may fit better.
What hidden costs should we expect?
Logs/traces/replays, retention overage, sampling/quota, SSO/audit, alerting/workflow, support/SLA, tax and migration. Sentry’s 5GB/5M/50 allowance and Datadog’s separate APM/RUM/logs both count.
How do we choose and accept?
Standalone: Sentry; already on Datadog APM/RUM: Datadog; 10M+: effective rate + platform; single user: Sentry free. A 2–4 week POC on real errors records errors, grouping, sampling, retention and the bill.
Research method and limitations
This article separates “official facts” from “editorial modelling”: Sentry’s Developer/Team 26/Business 80, 50k errors, 0.0003625/0.0002188/0.0001875 tiers and 5GB logs/5M spans/50 replays come from Sentry Pricing; Datadog’s <50k 25/36, 50k–100k 0.25/0.30/0.38, 100k–500k 0.21/0.25/0.32, 500k–10M 0.17/0.20/0.26 and APM/RUM error inclusion come from Datadog Pricing. The TCOs are arithmetic at 50k/100k/500k/1M/10M with a “25 base + overage” assumption, not vendor quotes.
Eight limitations: (1) only US public list prices are used, excluding tax, commitments/annual billing, enterprise discounts and regional differences; (2) only errors are counted, excluding logs/spans/replays/uptime/cron, APM/RUM/Infra, support/compliance and migration; (3) whether Datadog’s <50k flat stacks with >50k usage follows the page wording; this article estimates “25 base + overage”; (4) SDK coverage, error grouping, sampling, retention, alerting and SLA were not tested; (5) Rollbar, Bugsnag, Honeybadger and Elastic APM are excluded; (6) 50k/100k/500k/1M/10M are assumptions; (7) mobile symbolication/privacy/compliance are excluded; (8) prices and terms can change by contract, region and exchange rate. Treat this as a pricing-conversion template and replace assumptions with a 2–4 week real-error POC.
