AppSignal is an application performance monitoring (APM) platform that brings error tracking, performance monitoring, uptime checks, host metrics, log management, and anomaly detection into a single tool. Built with a lightweight Rust agent, it supports Ruby, Elixir, Node.js, Python, and more with minimal setup. AppSignal automatically instruments popular frameworks so you get actionable insights out of the box.
AppSignal officially supports Ruby (including Rails, Sinatra, Hanami, and Grape), Elixir (Phoenix, Plug, Ecto), Node.js (Express, NestJS, Next.js, Koa, Fastify), and Python. It also offers support for Go, Java, PHP, and Rust, plus OpenTelemetry compatibility for other languages.
AppSignal has a free plan that includes 50,000 requests, 1GB of log storage, and 5‑day data retention. Paid plans begin at around €18.25/month (about $23.25 USD) when billed yearly and include all features with unlimited users, apps, and hosts. You won’t get surprise overage charges, and going over your usage limits won’t stop monitoring or trigger unexpected bills.
Yes. AppSignal offers a 30-day free trial with no credit card required. You get full access to all features during the trial period.
Most users report getting up and running in under 10 minutes. For supported frameworks like Rails or Phoenix, AppSignal auto-instruments common libraries, so you get useful data immediately after installing the package.
Yes. AppSignal's data processing is GDPR compliant, which is important for teams with EU-based customers. Optional HIPAA compliance is also available as an add-on.
AppSignal is generally easier to set up and more focused than larger observability platforms. It provides core APM, error tracking, uptime monitoring, logs, and host metrics in one interface with predictable pricing that scales with usage. Competitors like New Relic or Datadog offer broader feature sets and deeper analytics at higher complexity and cost, which may be more than smaller teams need.
Yes. AppSignal integrates with Slack, GitHub, GitLab, PagerDuty, OpsGenie, webhooks, and more. You can send alerts and issues directly to the tools your team already uses.
