Do not let merge conflicts break your flow

Indicators in the gutter of your editor show the changes others are making. Computed from all active branches, the indicators update as you and your team code together.

Perform eager and continuous code review directly in your IDE with the team view. See who is online, their active branches and changes in a single repository or across your organization, updated in real‑time. Get notified when you fall behind the main branch or your tracking branch. Inspect the changed files in the repository view to know if they will merge cleanly with your own local changes before you pull.

Let your team know what you are working on

Connect your issue tracker to see each other's current issue in the team view. The issue you are working on is determined by your current branch and updates automatically. View your current issue and select another issue to work on via the status bar. Switching issues will check out an existing feature branch or create a new one for you if needed.

  • Video capture to record a particular user sequence
  • Element editor for making suggested changes to HTML and CSS elements
  • Text-based Comments
  • Tagging team members, emoji reactions and status designation per-comment make sure everyone is kept in the loop

👋🏽 About code review

Code review is the process of reviewing code written by one or more programmers in order to check for errors, improve the quality of the code, and ensure that it follows coding standards and best practices. This process typically involves a team of programmers who review the code and offer suggestions for improvements or changes.

Code review can be done manually, with the reviewers reading and analyzing the code line by line, or it can be done automatically using specialized tools that check the code for errors and potential issues. Code review is an important step in the software development process, as it helps to identify and fix problems early on, before they become more difficult and expensive to address.
