What AppSignal is

AppSignal is a cloud application monitoring service for developers, combining error tracking, performance monitoring, logs and tracing. It groups exceptions with backtraces and the deployment associated with them. Performance tools cover 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. Its MCP server lets AI assistants such as Claude, Cursor or Zed query production errors, traces and deploys. Supported languages include Ruby, Elixir, Node.js, JavaScript, Python, Go, Java, PHP and Rust, with integrations such as 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. Paid access starts at $23.25 per month with annual billing, and a 30-day full-featured trial does not require a credit card. AppSignal says it does not charge overages or stop monitoring when plan limits are crossed. The company says it was founded in 2012 and has dual headquarters in Amsterdam and Austin.
