AppSignal combines error tracking, performance monitoring, logs, and uptime checks in one developer-friendly APM platform, with a free tier.
AppSignal is an all-in-one APM platform, founded in 2012 in Amsterdam, that combines error tracking, performance monitoring, logs, host metrics, and uptime checks into a single product rather than requiring separate tools.
The company reports processing over 500 billion requests per month across its customer base and offers first-party support for Ruby, Elixir, Node.js, JavaScript, and Python, with OpenTelemetry-based coverage for additional languages like Go, Java, PHP, and Rust.
Features include exception tracking with full backtraces and deploy correlation, automatic slow-endpoint detection, full-text searchable logs linked to traces, configurable anomaly alerts, host and uptime monitoring, auto-generated dashboards, and AI-assisted debugging via MCP integration with tools like Claude, Cursor, and Zed.
AppSignal is usage-based, priced by request volume. A free plan covers 50,000 requests per month with no credit card required, and paid plans start around $25/month with every feature included on every tier and no separate feature gating. Add-ons cover long-term log storage, HIPAA compliance, and enterprise SSO.
