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 Merge?
Merge adds connectors and new models weekly while fixing ERP sync details underneath.
Merge ships weekly across Gateway, Unified and Agent Handler. October brought new Agent Handler connectors (Google Workspace, Ironclad, Zoom Phone, Meta Ads, TikTok for Business, Warp), Gateway support for GPT-6.1 Terra, Gemini 4 Argon and Mistral Large 4, custom prompt classifiers and a management API for security rules. Unified got NetSuite, QuickBooks, SharePoint and Jira sync fixes.
AppSignal vs Merge: editorial side-by-side
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.
Merge
5.0INFRA · APIS
Merge adds connectors and new models weekly while fixing ERP sync details underneath.
◆ Current state
Merge ships weekly across Gateway, Unified and Agent Handler. October brought new Agent Handler connectors (Google Workspace, Ironclad, Zoom Phone, Meta Ads, TikTok for Business, Warp), Gateway support for GPT-6.1 Terra, Gemini 4 Argon and Mistral Large 4, custom prompt classifiers and a management API for security rules. Unified got NetSuite, QuickBooks, SharePoint and Jira sync fixes.
◆ Where it's heading
Merge is positioning Gateway and Agent Handler as the governed path for enterprise AI, adding admin controls and API management alongside catalog growth. The Unified integrations business keeps getting steady correctness fixes rather than new categories.
◆ Prediction
Expect more connectors and same-week model additions in Gateway, plus more management-API coverage; pricing or packaging changes are not visible in the entries.
