Here are our docs on Code Channels: And the Slack docs:

Slack4 days ago

They say that everything good must come to an end; that's the beauty of Code Channels, too. ✨

Smart Flow | AI & Tech5 days ago

The IDE moving into Slack is the easy part. The hard part is the agent in that channel: who pays for the loop, where context lives, and what happens after a failed PR. Multiplayer is useless if every review burns a frontier pass.

Thats pretty neat!

This feels like a big step towards more interactive team dev

Mercurio Nevio5 days ago

Watching a PR get reviewed in Slack while the build happens live feels less like engineering and more like a high-stakes heist movie.

Mo Rajabi4 days ago

we should bring devin to inline. threads > "code channels"

Colbert5 days ago

This is a total game changer for remote pairing. Having the feedback loop integrated directly into the chat flow is going to save so much time on context switching.

IdeaAize5 days ago

Congrats on shipping this, Nader! Turning Slack into a multiplayer IDE with PR reviews and auto-edited demo recordings baked in is such a clever workflow 🔥 Big fan of how frictionless the collab loop looks.

John Rood5 days ago

ephemeral channels are right. the durable unit should be the decision log + PR + test receipt. otherwise deleting the room also deletes the team's memory of why the code exists.

Aamir4 days ago

This is huge for remote teams 💻 multiplayer coding in Slack is genius

Raz Michaels4 days ago

Whoa!

Is it possible to add my claude/codex/agy cli into slack channel and discuss to reach the agreements? that would be so much helpful to me.

A good teammate earns trust. They give you quality work and maybe most underrated, are a delight to work with Today we're launching Devin and Slack Code. We've worked with Slack on new primitives, bringing more of what makes Devin great into Slack. Now Devin can take more complex work and start a Code Channel, bringing team collaboration and more information about code diffs, PRs, and other files into the same work space. What makes Devin different is it has its own computer. It can deploy various OS/mobile platforms, test the code, and really prove that it did a good job to your team (like replying with a video recording). Better yet, Devin is a delight to work with in Code Channels. It jumps in when needed, consolidates feedback, and doesn't overburden your team with replies like other agents We're so excited to be working with Marc Benioff and team to bring this to market, we can't wait to see what you (and your team!) build

How is Cognition working with Devin in Slack Code? 👀👇 Devin follows the work as it happens, picks up a task from the engineering channel, opens a PR with a demo video, and brings in a designer to finish the UI. All without leaving Slack or waiting to be tagged. The agent isn’t off doing its own thing. The whole team is right there, building with it. That's the beauty of multiplayer AI in Slack.

StealthSDK has just implemented a game changing feature! Powered by SOTA reasoning models, you can now use Stealth to generate dynamic Lua snippets which are executed at runtime. This means our AI agents now have full control over the Roblox game code and players can even recreate entire Roblox games without writing a single line of code. The possibilities this feature brings are endless, and we are excited to see what you build with it. See our demo showcasing this functionality 👇

Reviewing AI-generated code is the new bottleneck. Writing code was slow before. Now, in a few minutes, you can generate virtually unlimited lines of code using AI. But developers are now spending 70% of their time checking that code. That's the new bottleneck. I've been using Cline, and they have a feature that actually helps with this: You can click a button and have Cline generate an inline explanation for every single line of AI-generated code. Take a look at the attached video. What it does: 1. You can read the code and the explanation together 2. You don't lose context while reviewing code 3. You understand the "why" behind each change And here is the best part: It works on any git diff. You can use it to review PRs, understand commits from other people, or catch up on a codebase you haven't touched in a while.

You can't build iOS apps without a Mac, so we gave Devin one. Devin Cloud Agents now run macOS, with Xcode, iOS simulator, and your signing setup, all in a real macOS environment (with full computer use). In this demo, Devin builds a native iOS game, then plays and tests it with computer use. Devin then sends a screen recording of the gameplay along with a test report for my review. With Namespace you get as many macOS environments as you'd like, configurable with many major versions of macOS operating system and Xcode.

You lose customers every time an agent like Codex or Claude Code uses your product and fails to complete a task. At Scope (YC P26) we built a feature to find those errors for you and fix them. Let’s use Vercel as an example to show you how it works! Want us to run a workflow for you? Drop it in the comments below :)

Watch Slack Code change the game. 👇 GitHub spins up a code channel, connects it to the repository, and gets to work on a fix. The team watches, weighs in, and builds alongside it, all in real time. Multiplayer AI? Check. All in Slack? Check. Check out the video? Check.
