Agentic coding is now multiplayer Introducing Slack Code

Software development has evolved from solo terminal coding to single-player AI copilots, to multiplayer coding with Slack Code. Instead of jumping between tools, teams and agents plan, build, and iterate together in the open, in a dedicated workspace.

Here's an example: a product manager spots a bug report in a channel. Instead of waiting on an engineer, the PM asks a coding agent to help architect a fix. That agent spins up a code channel, reviews the conversational context, screenshots, and docs already shared, and proposes code. The PM brings in an engineer to check the diff, run the preview, and give the agent the go-ahead to open a PR and merge to production. No ticket, no meeting, no waiting — just a fix, shipped.

What changes is who gets to build. Because the work happens in a tool people already use, someone without technical skills can help shape the output, without opening a terminal. Anyone in the channel can pause, redirect, or stop the agent if it drifts off track. Once the work’s done, the channel archives itself, so the sidebar stays tidy while the history stays fully searchable as institutional context. 

Slack is becoming the natural home for AI agents from our ecosystem of partners to meet people where they already work. Anthropic, Cognition, GitHub, ChatGPT, Vercel, and more are already developing in and for Slack Code, using our code channel APIs and bringing their coding agents into this shared space. The agents that developers, PMs, and designers already rely on can now tap into that same team context, right inside Slack.

Software engineering is just the start. Soon these APIs open to the broader developer community, so any custom agent, doing any kind of work, can join a code channel, whether that's a marketing team building a campaign or legal running a document review. As the partner network grows, Slack Code will become the place where every team, technical or not, builds with AI in the open.

As agents are becoming part of how teams work, Slack’s user experience is evolving too, so agents feel like real teammates everywhere, not just in code channels. Here’s what’s new:

• Agent DMs work like any conversation with a teammate: agents are clearly labeled, and threads get real titles so you can pick a conversation up where you left off.
• The new Agents tab gives every agent and agent session a home base. Browse all the agents, see your agent conversations, name them, check statuses, flag a blocked thread, or stop an agent mid-task.
• Add to Slack lets anyone build and ship an agent from NanoClaw, Lovable, Hyperagent, Superhuman, n8n, Vercel, ChatGPT, LangChain, Runlayer, or Skydive in just a few clicks. No migration, no complex setup. We've automated the OAuth, manifest setup, and environment config for you. Take a support assistant built on Lovable: click Add to Slack, and seconds later it's live alongside your team, with its own identity, right where the work happens.

The pattern holds everywhere : agents show up with a clear identity, follow the same channel norms as any teammate, and answer to the same admin controls IT already trusts, whether that's a code channel, a DM, or a project channel.

Agents in code channels inherit Slack's built-in security model, permissions, and admin controls from day one, without any additional IT lift. So, they work as secure extensions of your existing setup, with no new infrastructure or identities to manage.

Speed never comes at the cost of oversight. For high-stakes moves, like pushing code to production, the agent packages its work for an expert to sign-off on, right in the channel. That keeps people in control without slowing things down with separate IT approvals.

When a team works with AI out in the open, context compounds. Better context means better output, which makes AI more useful for the next person, and the next. Slack Code brings building out of isolated terminals and into dedicated code channels, while the broader agent experience makes every agent in Slack feel like a teammate, not just a tool. Together, that's the foundation for multiplayer AI.

This isn't just a new feature — it’s a new way to build software: open, collaborative, and powered by both human ingenuity and judgement and agent scale. Teams that build this way won't just move faster. They'll build things no one else can.
