Simplified Code Discussion

Rather than copying & pasting, CodeStream enables in-editor commenting on any code in your repository, with optional sharing to Slack, Teams or via email, with automatic at-mentioning of code authors via git blame.


Your teammates can participate in the discussion right from their IDE, or from Slack, Teams, or replying to the email.

Build the Knowledge Base Behind Your Codebase

CodeStream turns conversation into documentation by capturing all of the discussion about your code, and saving it with your code. Comment and code review threads are automatically repositioned as your code changes, even across branches. All with zero effort on your part.

Knowledge Base

Previously discussed questions and issues that explain important decisions are now accessible right where you need them, when you need them. Just click on the codemark to expand it and see how something works or why something was done a certain way.

Frequently Asked Questions

Where are messages stored?

Your team’s codemarks, which include the message text and the code snippet, are stored in the cloud on CodeStream’s servers. CodeStream uses best practices when it comes to security, but if your team has stringent infosec requirements we also offer an on-prem solution.
