SiteOS vs Sentry.
Different jobs, one website.
Sentry monitors application code: errors, tracing, logs, session replay and uptime, with Seer for AI root-cause analysis and fixes. SiteOS covers your website's errors, logs, traces and session replay too, alongside SEO and AI visibility, analytics, consent, forms, site search, browser checks on key journeys and checks that tracking fires, in one Project. This page compares SiteOS and Sentry on error tracking, debugging, uptime and browser checks, SEO, analytics, consent and forms, including where Sentry goes further.

YesPartly, with the condition in the notesNot offered
SiteOS is free, with monthly credits for research and checks. Sentry Team costs $26 a month billed yearly and Business $80, with usage-based extras; Seer costs $40 per active contributor a month.
Web analytics: Sentry measures performance and Web Vitals, not traffic sources.
Cookie consent banner: Sentry's docs leave the consent banner to your own CMP.
Forms with an inbox: Sentry User Feedback collects bug reports, not website forms.
Browser checks on key journeys: Sentry Uptime runs HTTP checks every 1 minute to 1 hour; scripted browser journeys are not described.
Error tracking: SiteOS Pulse Errors captures browser and server errors with source maps; Sentry also covers mobile and backend platforms.
Error SDKs for mobile apps and backend languages: Sentry's SDKs cover Android, iOS, React Native and Flutter, and backends such as Python, Java, Go, Ruby, PHP and .NET.
Recordings, logs and traces for debugging: SiteOS Pulse records masked replays of consented visits, server logs and traces through OpenTelemetry, and recordings of its own checks; Sentry records sessions, logs and distributed traces across more platforms.
Code profiling: Sentry's continuous and UI profiling are billed per profile hour from a pay-as-you-go budget.
Free plan: Sentry's Developer plan is free for one user.

Together
Use them
together.
Keep Sentry where it goes further: mobile and native SDKs, profiling, broad platform coverage and Seer's AI debugging. Use SiteOS for the website: its errors, logs, traces and replays next to search and AI visibility, analytics, consent, forms, site search, browser checks on key journeys and tracking checks. Your coding agent can work with both.
