Artifacts provides the foundation: repositories that can be created and forked programmatically, versioned storage for code and agent context, and the Git operations agents already know how to use.

With that foundation in place, you can focus on the layer above it: how agents coordinate their work, how changes are reviewed and merged, and what the developer experience should look like when hundreds or thousands of agents are working on the same codebase.

That is the layer we want you to build.

Now that Artifacts is in open beta, we’re holding a competition to see who can build the next Git platform on Cloudflare using Workers and Artifacts.

Artifacts is in open beta. Here’s why you should build on it

When we launched Artifacts, our goal was to make it possible to create a repository for every agent, session, task, or user — and to do that at the scale agents require.

Since then, we’ve seen developers use Artifacts in a range of ways: Vibe-coding platforms are using it to store the projects their users create. Developers are using it to persist the code and context from agent sessions. Others are creating isolated repositories, so multiple agents can safely work from the same starting point and compare or merge the results later.

Here are some new capabilities we’ve added since the initial launch.

Deploy Artifacts repos to Workers

You can now connect an Artifacts repository to a Worker through Workers Builds. When you or an agent pushes code to the Artifacts repository, Cloudflare will build the project and, for the production branch, deploy the updated Worker. Pushes to other branches automatically create or update Workers Previews, giving you an isolated, shareable version of your Worker where you can test changes before they go live.

You can connect an existing Worker to an Artifacts repository or start a new project and automatically store it in Artifacts.

using project = await env.ARTIFACTS.get("my-project");
const { defaultBranch } = await project.info();
const workspace = await project.fork(`task-${crypto.randomUUID()}`);

using repo = await env.ARTIFACTS.get(workspace.name);
const instructions = await repo.readFile({
  ref: defaultBranch,
  path: "AGENTS.md",
});

const agentTask = {
  remote: workspace.remote,
  token: workspace.token,
  instructions: instructions ? await instructions.text() : null,
};

export default {
  async queue(batch, env) {
    for (const message of batch.messages) {
      const event = message.body;
      if (event.type !== "cf.artifacts.repo.pushed") continue;

      await env.REVIEW_WORKFLOW.create({
        params: {
          namespace: event.source.namespace,
          repo: event.source.repoName,
          ref: event.payload.ref,
          commit: event.payload.after,
        },
      });
    }
  },
};
