Reproduce errors
using telemetry
Ever encountered an error which was impossible to reproduce? Not anymore.

This helps you reproduce & debug the issue even faster.

Make User fall
in love with product
Have a great product? Nice. ErrLytics gives you a better understanding of your product from user's perspective. It shows slow pages, API calls and errors which users encountered so that you can focus on those to make the user experience even better.
Our site is based highly on Javascript and we needed to see if there are any errors which our users are facing and most of the time a user do not send in feedback. ErrLytics also helps if there are any issues raised due to browser upgrades, plus the integration is just so easy.

How can I integrate ErrLytics with MVC frameworks like Angular, React, Ember, Vue etc.?
You don't need to. ErrLytics strictly believes in plug-and-play. You just have to put our code snippet at the top of your page and et voilĂ , You're good to go.
What do you count as a Hit?
A hit is any page view by the visitor that executes JavaScript and includes ErrLytics error reporting. We also count hits by bots like GoogleBot, AlexaBot etc. as it processes JS and we don't want our client's rank to go down because of any errors.
Does ErrLytics track user's input on my website?
No. We respect privacy. We just track the pattern of the input e.g. If user enter in input field, we track it as "15 characters email" format
Can I try out ErrLytics before choosing a plan?
We encourage you to. In fact, every new subscription starts with a 15 days trial of our popular Prototype plan.
Is my data secure?
Security of your data is crucial to us. We encrypt your data before it leaves your browser and send it over SSL only. We do not share your personal or application related data with anyone.
Is my credit card secure?

What if I exceed my plan usage?
We'll contact you to find the right subscription for your needs when your plan is about to exceed the limits. Don't worry, we will give you some time to take action even after you exceed limits.
Can I cancel my plan mid-term?
