OpenReplay vs Apache StreamPark: at a glance
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.
What is Apache StreamPark?
Five release candidates in two years, none of them stable, and none since October 2025.
StreamPark's tracked feed holds five release candidates spanning April 2024 to October 2025, and the notes are extremely thin — three of the five describe a single change each, one of them a Vue router naming bug. The most substantial entry, v2.1.7-rc1, lists four items: Maven argument validation, a license header consistency fix, a login authentication refinement and a Flink configuration file retrieval fix. No stable release appears anywhere in this record.

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.

0.0ANALYTICS
Five release candidates in two years, none of them stable, and none since October 2025.
◆ Current state
StreamPark's tracked feed holds five release candidates spanning April 2024 to October 2025, and the notes are extremely thin — three of the five describe a single change each, one of them a Vue router naming bug. The most substantial entry, v2.1.7-rc1, lists four items: Maven argument validation, a license header consistency fix, a login authentication refinement and a Flink configuration file retrieval fix. No stable release appears anywhere in this record.
◆ Where it's heading
Nothing in these entries describes new capability for the stream processing platform itself. The changes cluster around build tooling, authentication and the web console — the periphery of the product rather than its Flink and Spark job management core. Combined with a cadence of roughly two releases a year and a nine-month gap since the last one, the visible signal is a project in low-activity maintenance.
◆ Prediction
The entries do not support a prediction about direction. What they do warrant is checking whether development moved somewhere this feed does not capture, since a stream processing platform with no stable releases on record is more likely a tracking gap than a complete picture.
