Overview

Zed Industries, the company behind the Zed code editor, opened public beta access to Delta on September 16, 2026, according to Zed’s official blog. Delta is described in the announcement as “a multiplayer environment for coding with agents and reviewing what they build,” and the company frames it as the start of an effort to move development work away from GitHub’s pull-request model, as stated in the announcement.

What We Know

  • Delta first became available to a private beta group on August 12, 2026, when Zed said it was “inviting the first users into our private beta,” according to Zed’s introductory blog post.
  • With the public beta, Zed says Delta can now be downloaded for macOS, Linux, or Windows, used on the web without installation, or followed from a mobile browser, according to Zed.
  • Zed’s stated motivation is that “agents have fundamentally changed the way we write software, but our collaborative tooling isn’t keeping up,” per the company. It argues that because agents now generate large volumes of code, “the diffs we’re asking each other to review have mushroomed,” according to Zed.
  • Rather than reviewing static diffs, Delta lets teammates join a live “thread” alongside an AI agent. Collaborators “see the same worktrees” as the thread’s owner and “can work with them on their own machine,” and if the original participant logs off, others “can keep working with the agent where you left off,” per Zed’s announcement.
  • For review specifically, Delta supports a “dedicated review subthread” where each review gets “its own isolated copy of the parent thread’s worktrees,” so reviewers can explore or try changes with an agent without disrupting the original work, according to Zed.
  • The system is built on a data layer Zed calls DeltaDB, which the company says “extends Git’s content-based versioning with incremental versions based on deltas” and “records edits between commits alongside messages from humans and agents,” while a Git commit “remains the checkpoint you push, pull, and build from,” according to Zed.
  • Delta integrates with outside agent tools as well: Zed says it “connects to third-party agent harnesses, starting with Claude Code,” syncing a terminal session live into a Delta thread, per Zed’s introductory post.
  • Zed is not moving its own main code repository off GitHub. The company says “zed-industries/zed will remain on GitHub for now because it’s where our community finds issues and submits changes,” while contributors are encouraged to “share Delta threads alongside their pull requests,” according to Zed.
  • Zed says its own team has already moved off pull requests internally: “Last week, we crossed a key milestone: we disabled pull requests on Delta’s own repository,” and since then “33 of us have landed 570 changes to main since we turned off pull requests,” per the company.
  • Delta is free during the public beta. Zed says it will “introduce paid plans soon for individuals and teams” while promising “There will always be a free version of Delta,” according to Zed.

Framing

Zed positions pull requests as just the first piece of GitHub’s workflow it intends to displace, writing that “pull requests are the first part of the GitHub workflow we’re leaving behind” in favor of what it calls “continuous engineering,” according to Zed’s announcement. The company acknowledges it isn’t alone in this ambition, stating “it seems like everyone is in a race to replace GitHub right now,” while arguing that rival efforts largely still rely on “the same old primitives: branches, commits, and diffs,” per Zed. For continuous integration, Zed says the current approach is narrower than a full CI replacement: “an agent can trigger a run with an existing CI provider and check the results before landing the change,” according to the company.

What We Don’t Know

Zed has not disclosed pricing details for the paid plans it says are coming, nor a timeline for when they will launch. The company also has not said when, or whether, it plans to move its own primary zed-industries/zed repository off GitHub entirely.
