AppSignal vs Skipper
A side-by-side editorial comparison of AppSignal and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
AppSignal vs Skipper: at a glance
What is AppSignal?
AppSignal is turning distributed tracing into the default way to debug, one link at a time.
AppSignal shipped a run of tracing upgrades in two weeks: the service map left its feature flag, traces now link to host metrics and deploys, and cross-app services show by name instead of 'Unknown service'. Alongside that, OAuth tokens and the GraphQL API got tighter scoping and a cleaner log query model.
What is Skipper?
Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.
Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

AppSignal
5.0INFRA · APIS
AppSignal is turning distributed tracing into the default way to debug, one link at a time.
◆ Current state
AppSignal shipped a run of tracing upgrades in two weeks: the service map left its feature flag, traces now link to host metrics and deploys, and cross-app services show by name instead of 'Unknown service'. Alongside that, OAuth tokens and the GraphQL API got tighter scoping and a cleaner log query model.
◆ Where it's heading
The work points at connecting signals that used to live on separate pages: errors, traces, hosts, deploys and incidents. An MCP tool that lets agents count logs suggests the same connected data is being exposed to AI assistants, not just human dashboards.
◆ Prediction
Expect more agent-facing MCP capabilities built on the same trace and log data, likely starting with trace or error queries.
Skipper
5.0INFRA · APIS
Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.
◆ Current state
Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.
◆ Where it's heading
Zone-aware routing is being made safe for production, with guards against skew and fixes for a data race and silent misconfiguration. It currently works only in the routesrv mode, and the release notes say the direct Kubernetes mode needs the same filtering.
◆ Prediction
Expect zone filtering to be extended to the skipper-to-Kubernetes mode in a coming tag, as the v0.28.60 notes say is needed.
