Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
A side-by-side editorial comparison of OpenReplay and Apache SkyWalking — release velocity, themes, recent moves, and the top alternatives to consider.
OpenReplay's feed is Helm chart bumps behind its asset-cacher deny list.
OpenReplay's entries since November 4 are automated backup tags on the 1.26 and 1.27 lines that only increment Helm chart versions for chalice, assist-api and assist-stats. The last functional change remains the November 3 ASSETS_DENY_HOSTS option, which lets self-hosters block hosts the asset cacher may fetch, alongside a fix for EE 1.26 images that crashed on start.
SkyWalking 11.1 builds service maps from OpenTelemetry traces, no SkyWalking agent required.
Apache SkyWalking spent 2025 and 2026 rebuilding its foundations: BanyanDB replaced H2, the Groovy DSL runtime gave way to ANTLR4 and Javassist, and 11.0.0 split the UI out of the backend. Version 11.1.0, released November 6, stores OTLP traces as they arrive and adds a Trace Analysis Language that turns spans into service, instance and endpoint metrics, topology and dashboards for the databases, caches and queues those services call. Applications instrumented only with OpenTelemetry SDKs now get SkyWalking's dashboards without its agent.

The project is in a maintenance stretch, backporting fixes across 1.25 to 1.27 and repackaging charts. Nothing in recent entries points to new user-facing features.
Unclear from these entries; more chart-bump backup tags are likely until a 1.27.x release with notes appears.

After taking storage and runtime in-house, SkyWalking is opening its front door to OpenTelemetry data. Its value is shifting from its own agents toward the analysis it runs on any trace source.
Expect more TAL coverage and OpenTelemetry quick starts, with SkyWalking's own agents positioned as optional rather than required.
