What each product is

What makes these two tools different?

DebugBear

DebugBear is best understood as a suite.

DebugBear monitors web performance and Core Web Vitals continuously — running scheduled Lighthouse tests from its own infrastructure, surfacing CrUX field data from the Chrome User Experience Report, and alerting teams when scores drop below thresholds. It provides CWV trend dashboards, waterfall charts for diagnosing LCP root causes, and third-party script impact analysis. Primary audience: development teams and technical SEO professionals who need scheduled monitoring and alerting rather than on-demand audits.

DeepSEOAnalysis

DeepSEOAnalysis is an ungated audit.

DeepSEOAnalysis provides on-demand technical SEO auditing including CrUX p75 CWV — the same data Google uses for ranking decisions — alongside structured data validation, canonical hygiene, redirect chain analysis, and AI visibility scoring. No subscription required. Where DebugBear provides ongoing monitoring and CWV trend dashboards for teams who need continuous alerting, DeepSEOAnalysis provides comprehensive one-shot audits for SEO teams who need actionable findings across the full SEO stack immediately.

FAQ

Common questions

What is DebugBear used for?

DebugBear is a web performance monitoring platform used by development and technical SEO teams who need continuous alerting on Core Web Vitals and Lighthouse scores. Its primary use cases are: ongoing monitoring of CWV scores (LCP, CLS, INP) from both CrUX field data and scheduled Lighthouse synthetic tests, alerting when performance drops below defined thresholds (e.g. LCP exceeds 2.5 seconds), waterfall analysis for diagnosing the root cause of LCP regressions, third-party script performance impact analysis, and tracking the CWV impact of site changes over time. DebugBear is not a full technical SEO auditor — it does not validate structured data, check canonical tags, audit redirect chains, or score AI visibility.

Does DebugBear use CrUX data?

Yes — DebugBear surfaces CrUX (Chrome User Experience Report) field data alongside its Lighthouse synthetic testing. CrUX data in DebugBear shows the real-user CWV distribution (p75 values for LCP, INP, CLS) from actual Chrome browser sessions — the same data that Google uses for Core Web Vitals ranking assessment. This is one key difference between DebugBear and tools like SpeedCurve Lux or Raygun RUM: DebugBear surfaces CrUX as a first-class data source rather than relying solely on agent-sampled real user monitoring. DeepSEOAnalysis also reports CrUX p75 directly, but as an on-demand audit rather than through continuous monitoring.

How does DebugBear compare to SpeedCurve?

DebugBear and SpeedCurve are both web performance monitoring platforms with overlapping capabilities. Key differences: DebugBear explicitly surfaces CrUX field data alongside Lighthouse synthetic tests — making the Google ranking signal visible in the same dashboard; SpeedCurve's Lux RUM is its primary real-user data source (agent-based), which does not equal CrUX. DebugBear has a more accessible pricing model ($68/month self-serve) compared to SpeedCurve's enterprise-focused contact-sales pricing. SpeedCurve has stronger competitive benchmarking features (monitoring competitors in the same test run). Both focus on performance monitoring rather than full technical SEO auditing.

Do I need DebugBear and DeepSEOAnalysis?

They complement each other well for different stages of SEO work. DebugBear is ideal for ongoing performance regression monitoring — catching when a site update drops LCP below the 2.5-second threshold before it shows up in GSC CWV reports. DeepSEOAnalysis is ideal for comprehensive technical SEO auditing — checking structured data validity, canonical correctness, redirect chains, and AI visibility alongside CWV, in a single on-demand report. A workflow that uses DebugBear for continuous CWV alerting and DeepSEOAnalysis for periodic full-stack audits provides both the "is performance regressing?" monitoring and the "what SEO issues exist right now?" audit that a technical SEO programme needs.
