CodeStream provides an in-IDE platform for developers to discuss, review, and understand code, saving conversations alongside the codebase as contextual documentation. The product automatically builds a knowledge base linked to specific code blocks, helping teams pay down technical debt and retain institutional knowledge. Customers include Zenefits, Deloitte, and universities such as Carnegie Mellon. Users report code review time reductions of as much as 50% and improvements in code quality. CodeStream operates as a SaaS business with a free 30-day trial, free use for teams of five or fewer and for educational/open-source projects, and a $10 per user per month price for business customers of six or more, with higher-priced enterprise features. The company has raised a total of $8.8M to date and plans additional integrations and enterprise adoption in the near term. CodeStream offers a conversation layer on top of source code that lets developers select text, start threaded discussions, and @-mention teammates, opening the correct file and line in VS Code. The product integrates with Slack to create matching Slack threads and keeps conversation threads persistent so teams can review why changes were made even as code evolves. Today CodeStream supports VS Code with a split-pane UI showing threads alongside code; the company plans to add support for Visual Studio, JetBrains editors and Atom. CodeStream does not replace git commits or native code comments but complements them with a focused discussion layer. The company is still in beta and is free for now. It is Y Combinator–backed and recently completed a funding round.
