Apache HertzBeat vs OpenReplay: 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 OpenReplay?
OpenReplay handles dynamic HTML root swaps and iterates user journey analytics
OpenReplay's recent releases are primarily stability improvements and UX iterations on session replay and user journey analytics. The HTML swap handler in 0916 resolves a recording gap where apps that dynamically swap the root DOM element produced broken replays. User journey analytics received several targeted fixes — titles, event properties in breakdowns, clickmap renderer tweaks. Pre-v1.28.0 fixed three docker-compose upgrade failures that had blocked self-hosted upgrades.

◆ 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.
OpenReplay
5.0ANALYTICS
OpenReplay handles dynamic HTML root swaps and iterates user journey analytics
◆ Current state
OpenReplay's recent releases are primarily stability improvements and UX iterations on session replay and user journey analytics. The HTML swap handler in 0916 resolves a recording gap where apps that dynamically swap the root DOM element produced broken replays. User journey analytics received several targeted fixes — titles, event properties in breakdowns, clickmap renderer tweaks. Pre-v1.28.0 fixed three docker-compose upgrade failures that had blocked self-hosted upgrades.
◆ Where it's heading
OpenReplay is iterating on analytics depth (user journeys, breakdowns, clickmaps) while filling in session recording edge cases. The docker-compose upgrade reliability work suggests v1.28.0 is in active preparation and self-hosted deployment is a priority — important for a product competing on 'open-source alternative to FullStory/Hotjar' positioning.
◆ Prediction
v1.28.0 will likely ship the user journey improvements alongside docker-compose upgrade stability, positioning OpenReplay's self-hosted option more competitively for teams with on-premise replay requirements.
