Monitoring and observability
Both are offered as hosted services, so the useful comparison is each vendor’s track record, SDK and licence rather than version support. Datadog is a proprietary service; Sentry is source-available under FSL-1.1-Apache-2.0. In the last 90 days Datadog’s status feed logged 11 incidents and Sentry’s 22.
Last checked against Datadog Status, deps.dev, npm, OSV.dev, CISA KEV and Sentry Status.
Every value links to its source. Where a row doesn’t apply to one of them, the cell says why.

Comprehensive monitoring and analytics platform
Application error monitoring and performance tracking SaaS
From StackPrism’s curated notes. Pricing isn’t covered here: it changes often, so check each vendor’s pricing page.
These overlap less than the search suggests: Sentry started as error tracking and adds performance tracing and session replay, while Datadog is a full observability platform for metrics, logs, APM and security. The comparison matters when you want one tool for errors and traces.
Release lines and end-of-life dates come from endoflife.date, release counts from deps.dev’s publish dates, and advisories from OSV.dev, counted once per flaw even when it’s listed under several ids, and checked against CISA’s list of vulnerabilities known to be exploited. Status and incident history come from each vendor’s public status feed; licences from each project’s licence file or the vendor’s licensing page, linked in the table.
The data refreshes every few hours and the time it was checked is shown above. There’s no pricing and no overall winner: which one fits depends on your constraints. To see how the versions you actually run hold up, check your repo.
