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 GLAuth?

GLAuth's September releases are security dependency updates and build fixes.

GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.

AppSignal vs GLAuth: editorial side-by-side

A
AppSignal

5.0

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.

0.0

GLAuth's September releases are security dependency updates and build fixes.

◆ Current state

GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.

◆ Where it's heading

GLAuth is in maintenance after 2.5.0, with occasional security and build releases. No new features have shipped since April.

◆ Prediction

Expect occasional 2.5.x security updates; the entries give no sign of the next feature release.
