Instead of branches and PRs, teammates join live threads to watch agents work and can spin up review subthreads with full context. Underneath is DeltaDB, an incremental, delta-based versioning layer that tracks edit-level activity below Git commits while staying compatible with existing Git workflows. Zed's own team of 33 has already landed 570 changes via Delta threads and disabled PRs internally, though its public open-source repo still uses conventional PRs. The company frames Delta as a first step toward eventually replacing GitHub.com entirely. Competitors are chasing similar ideas: Cursor is building 'Origin' and GitLab has 'Project Switch.' Delta beta is free on macOS, Linux, Windows, and web, with paid plans coming later. ## Content Zed has launched the public beta of Delta, a collaborative coding environment that replaces GitHub-style pull requests with shared, multiplayer threads. The argument is straightforward: pull requests were designed for humans reviewing human-written code, and that model doesn't hold up well when AI agents are doing most of the work. ## How it works Instead of pushing a branch and opening a PR, teammates join live threads where they can see the same worktrees and watch agents work in real time. If you want to dig into a specific decision, you can spin up an isolated review subthread that carries the full context of what the original agent was doing and why. Underneath all of this is DeltaDB, a versioning layer that records edit-level activity below the Git commit level. It's incremental and delta-based, which means teams don't have to abandon Git entirely to use it. Existing workflows stay intact. ## Zed is already using it internally 33 people on Zed's team have landed 570 changes to main through Delta threads, and the company has disabled pull requests on its internal repository. The public open-source repo will keep using conventional PRs for now, but Zed says it plans to move fully off GitHub for internal development within months. The longer-term goal is broader: Zed frames Delta as the first step toward replacing GitHub.com entirely, starting with Git storage and eventually adding CI-style verification inside threads. ## The competitive picture Zed isn't alone here. Cursor is working on something called Origin, and GitLab has Project Switch. There's a real race to figure out what code collaboration looks like when agents are writing most of the code, and nobody has a definitive answer yet. The Delta beta is free and available on macOS, Linux, Windows, and web. Paid plans are coming later. ## Questions this post answers ### What is Zed's Delta and how does it replace pull requests? Delta is a collaborative coding environment from Zed, now in public beta, that replaces GitHub-style pull requests with shared, multiplayer threads. Teammates join live threads to watch AI agents work in real time, and can spin up isolated review subthreads carrying full context. It runs on DeltaDB, an incremental, delta-based versioning layer tracking edit-level activity below Git commits, while remaining Git-compatible. It's free on macOS, Linux, Windows, and web. _Teams rethinking code review for agent-driven workflows can follow tools like Delta as they evolve on daily.dev._ ### Is Zed actually using Delta internally instead of pull requests? Yes, 33 people on Zed's team have landed 570 changes to main through Delta threads, and the company has disabled pull requests on its internal repository. The public open-source repository still uses conventional pull requests for now, but Zed plans to move fully off GitHub for internal development within months. _Engineers weighing early internal adoption of new dev tools can track real-world usage stories like this on daily.dev._ ### What other tools are competing with Zed's Delta for AI-agent code collaboration? Cursor is building a similar tool called Origin, and GitLab has one called Project Switch. Both are part of a broader push to rethink code collaboration workflows for a world where AI agents write most of the code, alongside Zed's Delta, though none of these tools has established a definitive standard yet. _Anyone comparing emerging agent-first collaboration tools can track how Delta, Origin, and Project Switch evolve on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@andradei** · 1 upvotes > Interesting field. And judging by how GH is moving these days, it might not keep up. **@ristotoldsep** · 1 upvotes > PRs are already meetings with diffs attached. Curious if live threads make review calmer. **@trevorsuna** · 0 upvotes > Live threads can preserve far more decision context than a finished pull request, especially when agents produce many small edits. I’d still want durable review checkpoints, signed verification results, and an exportable Git history; synchronous collaboration should improve review without making audits or asynchronous handoffs dependent on one tool. ## Similar posts on daily.dev - [Software Is Made Between Commits — Zed's Blog](https://daily.dev/posts/software-is-made-between-commits-zed-s-blog-85az94983) · Zed · 43 upvotes · 5 comments --- Tags: [#github](https://daily.dev/tags/github), [#ai-agents](https://daily.dev/tags/ai-agents), [#code-review](https://daily.dev/tags/code-review), [#version-control](https://daily.dev/tags/version-control), [#zed](https://daily.dev/tags/zed) [View this post on daily.dev](https://daily.dev/posts/zed-launches-delta-public-beta-to-replace-pull-requests-with-ai-agent-friendly-threads-bdw45yvux) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Zed launches Delta public beta to replace pull requests with AI-agent-friendly threads","url":"https://daily.dev/posts/zed-launches-delta-public-beta-to-replace-pull-requests-with-ai-agent-friendly-threads-bdw45yvux","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/zed-launches-delta-public-beta-to-replace-pull-requests-with-ai-agent-friendly-threads-bdw45yvux"},"datePublished":"2026-09-16T20:00:27.552Z","dateModified":"2026-09-16T20:01:09.965Z","description":"Zed has launched the public beta of Delta, a collaborative coding environment designed to replace GitHub-style pull requests with shared, multiplayer threads...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/d85d124d185f12f61efe823f9dfd98f5?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/d85d124d185f12f61efe823f9dfd98f5?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":3,"discussionUrl":"https://daily.dev/posts/zed-launches-delta-public-beta-to-replace-pull-requests-with-ai-agent-friendly-threads-bdw45yvux","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":31},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":3}],"keywords":"github,ai-agents,code-review,version-control,zed","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"Zed launches Delta public beta to replace pull requests with AI-agent-friendly threads"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/zed-launches-delta-public-beta-to-replace-pull-requests-with-ai-agent-friendly-threads-bdw45yvux","comment":[{"@type":"Comment","text":"Interesting field.
