HyperDX vs OpenReplay: at a glance
What is HyperDX?
HyperDX 2.42 lets dashboards be authored from the CLI and adds an MCP service-health report.
The 2.42 release train adds dashboard and saved-search authoring to the hdx CLI (list, export, create, import, round-trip JSON), returns PromQL tiles through the external dashboards API, and gives the MCP server a one-call per-service health report. The app moves alert editing into a side panel next to the chart and adds a content font size setting; the collector can now send PromQL remote-write over HTTPS.
What is OpenReplay?
OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.
On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

HyperDX
5.0ANALYTICS
HyperDX 2.42 lets dashboards be authored from the CLI and adds an MCP service-health report.
◆ Current state
The 2.42 release train adds dashboard and saved-search authoring to the hdx CLI (list, export, create, import, round-trip JSON), returns PromQL tiles through the external dashboards API, and gives the MCP server a one-call per-service health report. The app moves alert editing into a side panel next to the chart and adds a content font size setting; the collector can now send PromQL remote-write over HTTPS.
◆ Where it's heading
HyperDX is making its dashboards and alerts manageable outside the UI, through the CLI, the API and MCP tools, while PromQL becomes a full citizen next to ClickHouse logs and traces. Ad hoc dashboard filters and OTel event-name fields are being laid down for later use.
◆ Prediction
Expect MCP dashboard tools to gain PromQL tile editing and the new event-name and severity fields to start driving log views.
OpenReplay
5.0ANALYTICS
OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.
◆ Current state
On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.
◆ Where it's heading
The release feed is all maintenance: dependency and runtime upgrades backported to several self-hosted lines at once, published as timestamped backup tags without feature notes. The quick follow-up fix shows the pgx migration is touching real query paths.
◆ Prediction
Expect more backup tags as the pgx v5 change reaches 1.22 and any further query fixes land; nothing in the entries points to a feature release.
