What is Apache SkyWalking?

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.

What is Grafana Loki?

Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.

Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

Apache SkyWalking vs Grafana Loki: editorial side-by-side

A3.8

SkyWalking 11.1 builds service maps from OpenTelemetry traces, no SkyWalking agent required.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

Expect more TAL coverage and OpenTelemetry quick starts, with SkyWalking's own agents positioned as optional rather than required.

6.3

Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.

◆ Current state

Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

◆ Where it's heading

Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.

◆ Prediction

Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
