# Best JavaScript Application Monitoring Tools in 2026

Application Monitoring Tools prevent uncaught exceptions and errors from going
unnoticed. Most tools offer automated instrumentation, enabling your application
to recognize and ship the error messages for further processing automatically.

Most Web applications are made using JavaScript. It's around
[95% of websites](https://w3techs.com/technologies/details/cp-javascript). So
most issues occurring on websites are most probably due to JavaScript.
JavaScript Applications Performance Monitoring helps to prevent these
unnecessary outages and errors.

**Main Benefits of JavaScript Performance Monitoring:**

- Frontend APM tools help to reduce latency, which is key for driving up the
  number of conversions
- End-to-end observability into the frontend and its dependencies help to spot
  underlying performance issues across the entire stack

Relying solely on web browser profiling tools is not a viable option. The market
is full of frontend monitoring solutions ranging from lightweight and
open-source all the way to SaaS Enterprise-ready Tools. Let's take a look at
some of the best of them available in 2026.

## Conclusion

JavaScript is one of the most popular and widely-used languages in the world,
which also allows for the creation of countless client-side libraries and
frameworks. New web applications are deployed all the time, so the chances of a
breakthrough come down to speed and reliability. APM tools reduce the number of
performance-related issues and prevent them from escalating to an outage.
Knowing all this, there is no reason to neglect JavaScript monitoring,
especially in 2023. For further resources on APM head over to our list of the [best application performance monitoring tools](https://betterstack.com/community/comparisons/application-performance-monitoring-tools/).
