The next era of productivity is agentic—and it lives in Slack. We’re calling on all builders—from seasoned Slack veterans to "vibe coders" picking up the Slack CLI for the first time—to join the Slack Agent Builder Challenge. This is your opportunity to redefine the workplace by building intelligent agents that automate workflows, surface real-time insights, and connect systems in ways we haven’t imagined yet. Whether you’re building a specialized agent for your organization, a tool for social good, or the next viral Slack Marketplace app, we want to see your creativity in action. Leverage the Slack Agent Builder, MCP integrations, and the Real-Time Search (RTS) API to show the world why Slack is the ultimate surface for AI. Why Join? Whether you're a "vibe coder" or a seasoned pro, the on-ramp is designed for speed—use the slack create agent command and ready-made templates for HR, IT, and Sales to go from an idea to a running agent in a single afternoon. For those building for organizations, the hackathon serves as a guided path to the Slack Marketplace, giving you a structured deadline to ship your app and gain direct distribution to Slack’s massive enterprise customer base. Compete for a share of the $42,000 cash USD prize pool, a chance to go to Dreamforce 2026, some Slack swag, an invite to an exclusive Slack community gathering and to be featured in the Slack newsletter and social media.
