Fusion’s code panel just got a serious upgrade. Files now stay in sync automatically thanks to a built-in watcher. We added a global search UI that feels like your favorite IDE, plus a "New Changes" view that makes it easy to jump through modified files fast. Learn more.
Plan Mode lets you think through a feature with Fusion before any code is generated. You can explore edge cases, refine requirements, and get a full implementation plan, but Fusion won’t create or modify files until you click Implement Plan. It’s a safer way to make sure the feature you ask for is the feature you actually want.

Tag @builder.io to request a new feature, tweak an existing one, or ask for changes. Fusion reads the context, links it to your project, and starts building instantly.
Everyone stays in the conversation while Fusion handles the implementation. When the bot finishes, it drops updates and previews right back in the thread, keeping the team in sync without leaving Slack.
Assign Jira tickets directly to the Builder bot and it reads the requirements, creates a branch, and starts implementing. The bot understands acceptance criteria and user stories and turns them into actual features. Comment on tickets with updates and the bot responds with code changes.
