Instabug Web SDK 1.0

This library is built with love by Instabug's team as a free tool to help developers build better websites and is not part of any of Instabug's current subscription plans.


Instabug web SDK is an open-source javascript library that provides an easy way to report bugs from your website with all the details to help you reproduce and fix the bugs faster.

Your users and testers can attach a screenshot with annotations to highlight the issue, a description of the bug they spotted and their email. In addition, more details are automatically captured:

  • Device
  • OS
  • Current view
  • Locale
  • Session duration
  • Screen size
  • Density
  • Locale storage
  • Console logs


To start using Instabug, you need to have an account on the following tools:

  • Zapier: to receive your bug reports on a variety of tools: email, Jira, Tello, Slack, etc.
  • Cloudinary: to host the screenshots included in the bug reports online.

Node engine compatibility:

  • we're using eslint@5.x.x module which requires node engine versions 6.14.0 or 8.10.0 or >= 9.10.0.
