Build on the platform that agents and AI call home.
What do you want to build next?
Building is a team sport.
Slack Code is where humans and agents build together. Each code channel is a dedicated space for one task, where your agent shares its plan, diffs, and live previews, and your team can weigh in as the work happens. Build your own agent with the code channels APIs and give your users a shared place to work.
