AppSignal

Dutch-built, founder-led, errors plus performance for Ruby and Elixir teams.

By AppSignal B.V. · Founded 2013 · Amsterdam, Netherlands · private

AppSignal is the Dutch-built, founder-led indie option that bundles error tracking, performance monitoring, host metrics, log management, and uptime in a single platform. Founded 2013 in Amsterdam by Robert Beekman and Thijs Cadier. Strong Ruby on Rails heritage that has expanded to first-class Elixir, Node.js, Python, and Ruby support. The advantage vs Honeybadger: AppSignal goes deeper on performance and adds real APM-style insights at indie pricing. The trade-off: smaller US presence, less SDK coverage outside the Ruby/Elixir/Node/Python core. For Ruby and Elixir teams especially, AppSignal is often the strongest fit when you want errors plus performance from one founder-led vendor without the Sentry platform creep or the Datadog price tag.
