# AppSignal

Error tracking bundled with performance monitoring, priced by requests in euros, with a free plan and unlimited users on every plan.

55 points out of 100. #9 of 12 error monitoring tools. Vendor: AppSignal B.V.. Website: https://www.appsignal.com/

- The paid plan costs €219 a year (€18.25 a month) for 250,000 requests a month, with unlimited users [1].
- The free plan allows 30,000 requests a month with 5-day retention [1].
- Stack traces for exceptions are kept for at least 30 days [1].
- AppSignal says its data sits in ISO 27001 certified facilities in the Netherlands [1].
- Docs list no iOS, Android, React Native, Flutter or .NET library [2].

Verdict: AppSignal suits web teams on Ruby, Elixir, Node.js, Python or PHP who want error tracking and performance in one plan with unlimited users [1][2]. Source maps, breadcrumbs, deploy markers and alerts to Slack, Teams, PagerDuty and email are documented [1][3][7][8][9]. The catch: pricing counts requests, not error events, there is no mobile or .NET library, and SAML sign-in is a business feature [1][2]. Best for: Ruby, Elixir, Node.js and Python teams that want errors and performance in one tool.
