Announcing Builder 2.0 We raised $67M to build collaborative coding for Claude and Codex - Start tasks from a local branch, Slack or Jira - Real-time collab between humans and agents - 100s of parallel agents code, test, review Reply "Builder" and I'll DM you 500 agent credits

Start the hard engineering work in Claude Code, Cursor or Codex. Push your branch to Builder. Your team takes it from there. A designer fixes the UI. PM adjusts requirements. QA finds bugs. All without pulling engineering back in.

Tag @ Builder in any Slack channel. It reads the thread, spins up a branch, and starts building. Updates drop back into the same thread. Assign a Jira ticket to Builder. It reads your acceptance criteria and starts implementing.

Builder 2.0 is built for real-time collaboration. A PM spins up a branch and starts building. A designer joins and refines the UI using the design system. An engineer reviews the code. All in parallel.

Every change ships as a pull request. Your review workflow stays intact. AI review agents catch issues before humans look. QA agents automate a browser to click through updates and send videos of bugs they find.

Each agent runs in its own cloud container with a full dev environment and browser preview. Assign a batch of tickets. Walk away. Come back to finished pull requests.

A visual editor that outputs real production code. Your design system stays enforced. Figma-to-code across React, Vue, Svelte, Angular. Prompt-driven changes. No one needs to know React to adjust a component layout.

Builder's Chrome extension connects to your running site or web app, even localhost and auth-walled pages. Select any element. Change it visually. Push it to code. You can also capture any layout from the web and bring it into Builder.

The same agentic capabilities are coming to Publish, Builder's CMS. A chat interface inside Builder where an agent generates personalized pages from your customer data, spins up variations, runs tests, and iterates.

Great work team!

Congrats Steve!!

thanks Yaser!

Builder lets go, I need to go as parallel as possible this seems like the right day

Criminal smooth animation !! ❤️🌺

@FabianHiller do i need to reply or are you gonna gimme? 🙂

This is timely! I’m basically building this in-house. Do you support bringing our own agents and hook to other sources like Microsoft Teams?

oh very cool, would love to hear more about what you're up to. teams support is on the roadmap, and we have a couple ways to hook into your own agents too

Builder Nice! Looking into for a new job I'm starting at, perfect timing on 2.0 releas!

The jump from idea to $67M is where most AI projects stall. What made this one stick?
