Plerdy Error Tracking Tool for Websites automatically monitors JavaScript errors, 404 errors, 5xx server errors, AJAX failures, and unhandled promise rejections in real time. No extra setup.

Bought it and didn't use it as there were no sites. As soon as I started building sites, I started connecting the tool to them and using it very often. At first I didn't understand it a bit, then I got into it and started to understand the customer journey. Where there were misunderstandings, the responsive support team helped a lot so there was an ease of implementation as well as ease of integration to my Search Console.

When you need to go deeper than simple analytics and want to check out heatmaps and video recordings of your products, Plerdy is a great solution. It also has some nice SEO tools, and even an AI reporting assistant. When you want to go deep on your site's performance, I recommend Plerdy.

They've made a lot of updates that are bringing me back. I was able to get this when it was on AppSumo. It is a very good tool, but I just didn't have the wherewithall to incorporate all the features and really digest the extensive setup and documentation. That's my fault. I see the improvements to the overall experience and I am going to start using it more extensively.

No. Error tracking works through the Plerdy tracking script. Once the script is installed, Plerdy can start collecting website errors automatically.
Plerdy tracks JavaScript errors, broken 404 resources, server 5xx errors, AJAX 4xx/5xx failures, and unhandled promise rejections.
You can see affected sessions, affected pages, devices, browsers, operating systems, countries, and the pages where each error happened.
Yes. Each error includes the message, file, line/column, URL, and last user action before the error. This gives developers clear reproduction context.
No. Developers use it to fix issues, but owners, marketers, QA, and product teams use it to understand impact: how many sessions were affected and which pages are losing users.
Start with critical 5xx errors, checkout/form errors, high-hit JavaScript errors, and issues affecting mobile users or revenue pages.
