What AppSignal is
AppSignal is a cloud application monitoring service for developers, combining error tracking, performance monitoring, logs, and tracing. Error tracking groups exceptions with backtraces and the associated deployment. Performance monitoring covers response times, throughput, slow endpoints, and slow queries. Log management includes full-text search, attribute filters, saved queries, live tail, and alerts based on log patterns. The service supports distributed tracing, transaction tracing, and log correlation. Its MCP server lets AI assistants such as Claude, Cursor, or Zed query production errors, traces, and deploys. AppSignal lists support for Ruby, Elixir, Node.js, JavaScript, Python, Go, Java, PHP, and Rust, with integrations including Slack, GitHub, Jira, Linear, GitLab, and PagerDuty. The free plan includes 30K requests, 1GB logging, five-day retention, and unlimited users, teams, applications, and dashboards. The company says it does not charge overages or stop monitoring when accounts cross plan limits.
