AppSignal
Dutch application monitoring that combines error tracking with performance metrics for Ruby, Elixir, Node.js and more.
AppSignal is an application performance monitoring and error-tracking service run by AppSignal B.V. in the Netherlands. It collects exceptions, slow requests, host metrics and custom data from frameworks like Ruby on Rails, Elixir/Phoenix, Node.js and Python.
It unifies error tracking, performance dashboards, anomaly alerts and uptime checks behind a friendly interface, with data hosted in Europe under GDPR. For teams that want errors and performance in one EU-hosted tool, it is a European alternative to Sentry, Datadog and New Relic.
