21 Best Web Application Monitoring Tools for Developers 2023

With any of these powerful monitoring tools for web developers, you can be safe and sound that your application or website operates flawlessly at all times – which it must.

What is happening with your apps? How about your server? When was the last time you analyzed your logs? Probably never! We don’t blame you, the manual process of analyzing and monitoring a server can feel like a ton of work, and it is.

But monitoring has some intense benefits to take advantage of, especially in application/server security. Moreover, it also helps understand how your users use your app and what you can do to improve the user experience.

Use monitoring tools for performance improvements

Believe it or not — there’s a lot of room for improvements, even if you think you have done everything in your power. There’s always something more, and these apps/tools will tell you exactly what it is.

Monitoring is all about understanding the connection between the app and the server, the app, the user, and all the other wonderful variations you can imagine.

When this post was first proposed as an idea, we didn’t seem to think much of it, yet that was also when it struck us, during our research, that there is huge demand for monitoring tools. Especially for uptime monitoring, general server health monitoring, and user accessibility monitoring.

All these categories have tens of startups working hard on producing the best possible tool to solve the given issue. We had some fun and learned that out of the 100+ tools on the market right now, about 30 of them are worth a mention of their own. Not because they have great communities behind them, but because they achieve the result of smooth monitoring functionality without much interference to your workflow.
