Apache HertzBeat vs Microsoft Clarity
A side-by-side editorial comparison of Apache HertzBeat and Microsoft Clarity — release velocity, themes, recent moves, and the top alternatives to consider.
Apache HertzBeat vs Microsoft Clarity: at a glance
What is Apache HertzBeat?
A monitoring project whose public release feed skips the release that mattered.
HertzBeat's tracked entries cover four release candidates, and the record is patchy — v1.7.1 through v1.7.3 in mid-2025 carry no notes beyond a merge commit or a signoff line, then an eleven-month gap to v1.9.0-rc1 in July 2026. The 1.8.0 release never appears in the feed at all despite v1.9.0-rc1's own changelog referencing 1.8.0 documentation and download page updates, so this record is missing a version. What v1.9.0-rc1 does show is a split of hertzbeat-common into core and Spring modules, monitoring template fixes and broad internationalization work.
What is Microsoft Clarity?
Microsoft Clarity builds out AI visibility analytics with bot page classification
Microsoft Clarity has pivoted materially toward AI crawl and citation analytics over the past several months. The product now surfaces AI-specific metrics across three surfaces: bot traffic analysis (page classification, robots.txt violation tracking), citation dashboards (branded vs. non-branded queries, topic grouping), and referral attribution (which AI crawlers drive actual site visits). This is no longer just a heatmap and session recording tool — AI visibility analytics is now a distinct product pillar.

A monitoring project whose public release feed skips the release that mattered.
◆ Current state
HertzBeat's tracked entries cover four release candidates, and the record is patchy — v1.7.1 through v1.7.3 in mid-2025 carry no notes beyond a merge commit or a signoff line, then an eleven-month gap to v1.9.0-rc1 in July 2026. The 1.8.0 release never appears in the feed at all despite v1.9.0-rc1's own changelog referencing 1.8.0 documentation and download page updates, so this record is missing a version. What v1.9.0-rc1 does show is a split of hertzbeat-common into core and Spring modules, monitoring template fixes and broad internationalization work.
◆ Where it's heading
The visible direction is structural cleanup rather than new monitoring coverage — separating framework-agnostic code from Spring-specific code is the kind of refactor a project does when it wants the core embeddable elsewhere. The internationalization work and Apache graduation blog point at a project investing in the things that widen a contributor base. The revert of MongoDB user account metrics within the same candidate suggests new collectors still land unevenly.
◆ Prediction
Expect the common module split to continue and MongoDB account metrics to return once the issue behind the revert is resolved. The missing 1.8.0 entry is a feed gap worth confirming before treating the eleven-month silence as real.

5.0ANALYTICS
Microsoft Clarity builds out AI visibility analytics with bot page classification
◆ Current state
Microsoft Clarity has pivoted materially toward AI crawl and citation analytics over the past several months. The product now surfaces AI-specific metrics across three surfaces: bot traffic analysis (page classification, robots.txt violation tracking), citation dashboards (branded vs. non-branded queries, topic grouping), and referral attribution (which AI crawlers drive actual site visits). This is no longer just a heatmap and session recording tool — AI visibility analytics is now a distinct product pillar.
◆ Where it's heading
Clarity is building an analytics layer for the AI search era, measuring how AI systems consume and cite content rather than only how humans navigate it. The consistent weekly shipping cadence in this space — page classification, scrape-to-referral, topic insights, query segmentation — signals deliberate expansion, not experiments. The next logical layer is competitive benchmarking: how does your site's AI citation share compare against peers by topic?
◆ Prediction
Clarity will add competitive benchmarking for AI citation share across topic areas, mirroring how traditional SEO tools provide keyword gap analysis against competitors.
