Compare the Top API Monitoring Tools in Europe as of October 2025

What are API Monitoring Tools in Europe?

API monitoring tools are software solutions designed to track the performance of an application programming interface (API). These tools can provide insights into API errors, request routing, latency, and other key metrics. They also help identify potential issues such as broken calls or security susceptibilities. Additionally, API monitoring can be used to log all calls made to the API and alert users of any unexpected behaviour. Furthermore, some API monitoring tools are able to recognize trends in user requests that could indicate a need for increased capacity or improved design. Finally, these tools are typically cloud-based and easy to integrate into existing architectures without requiring significant changes. Compare and read user reviews of the best API Monitoring tools in Europe currently available using the table below. This list is updated regularly.

    IBM Instana
    IBM Instana is the gold standard of incident prevention with automated full-stack visibility, 1-second granularity and 3 seconds to notify. With today’s highly dynamic and complex cloud environments, the average cost of an hour of downtime can reach six figures and beyond. Traditional application performance monitoring (APM) tools simply aren’t fast enough to keep up or thorough enough to contextualize the issues identified. Also, they are typically limited to super users who must complete months of training to learn. IBM Instana Observability goes beyond traditional APM solutions by democratizing observability so anyone across DevOps, SRE, platform engineering, ITOps and development can get the data they want with the context they need. Instana Dynamic APM operates using the Instana agent architecture, which incorporates sensors—lightweight, automated programs tailored to monitor specific entities.

    Integration Eye
    Integration Eye® is a modular product, which streamlines system integrations, infrastructure, and business. It consists of 3 modules: proxy module IPM, logging module ILM, and the security module ISM, which can be used independently or combined. It is based on the widely used, secure, and platform-independent Java language (why choose Java?) and it runs on the lightweight integration engine Mule™. Using individual Integration Eye® modules, you can monitor your APIs and systems, create statistics on and analyze calls (logging with the ILM module), and be alerted to any problems, downtime, or slow responses of specific APIs and systems. You can secure your APIs and systems using roles (authorization and authentication with the ISM module) based on Keycloak SSO we deliver or your existing Auth server. You can extend or proxy service calls (both internal and external) with mutual SSL, headers, etc. (proxy with IPM) you can also monitor and analyze these calls.
