An Editor Built Like a Video Game

On April 29, 2026, Nathan Sobo published the Zed 1.0 announcement post on Zed's blog. The post landed on Hacker News at 2,047 points and 663 comments — the highest-engagement HN story in the present cache by a substantial margin. The launch announcement is a milestone marker after five years of development, roughly a million lines of Rust, and a custom GPU-accelerated UI framework called GPUI that the Zed team built from scratch rather than building atop Electron, Chromium, or any other browser engine. The structural argument Zed has been making for the last several years is condensed in one sentence from Sobo's post: "Instead of building Zed like a web page, we built it like a video game, organizing the entire application around feeding data to shaders running on the GPU."

The video-game framing is not metaphorical. Zed's editor surface is composited by feeding glyph atlases, syntax-tree-derived color spans, and pane-layout geometry into GPU shaders the way a video-game engine composites its frames. The reason this matters is the reason the Zed team gave for starting over from the Atom era: Atom was built as a fork of Chromium, and the same team that built Atom is the team that spawned Electron. The Atom-Electron-VSCode lineage is, in the historical-causal sense, Zed's own. Sobo's post is unusually direct about the inherited limitation: "Electron eventually became the foundation of VS Code (which today seems to be forked into a new AI code editor every other week). Web technology offered an easy path to shipping flexible software, but it also imposed a ceiling. No matter how hard we worked, we couldn't make Atom better than the platform it was built on." The 1.0 announcement is, in part, a statement that the rebuild from scratch has finally cleared that ceiling.

Who built it

Zed's three co-founders all worked on Atom at GitHub before founding Zed Industries in 2021. Nathan Sobo led the Atom team from 2011 to 2018; he also co-led Teletype for Atom, one of the first production deployments of conflict-free replicated data types for collaborative text editing. Max Brunsfeld joined the Atom team in 2013 and, in parallel with the Atom 1.0 push, built Tree-sitter, the incremental-parsing framework that now underlies syntax highlighting and code intelligence in Atom's successors, including Zed itself, Neovim, and Helix. Antonio Scandurra joined Atom in 2014 while still in university and partnered with Sobo on the Teletype work that became Zed's collaborative substrate. Redpoint Ventures led a $10M Series A in March 2023; Sequoia led a $32M Series B in August 2025.

The three-person founder bench is a useful data point because it makes the built it like a video game claim load-bearing rather than rhetorical: the team that built Atom, the team that wrote Tree-sitter, and the team that productionized CRDTs for collaborative editing is the same team writing Rust shaders for Zed. The 1.0 milestone is the artifact of that team's second attempt at the editor problem, with the lessons from the first attempt informing every layer.

The AI-native positioning

The piece of Zed's 1.0 framing that most directly addresses 2026 is the AI integration model. Sobo's post: "Zed is also an AI-native editor. You can run multiple agents in parallel, and edit predictions suggest your next change at keystroke granularity and with the speed you've come to expect from Zed. The Agent Client Protocol opens Zed up to a growing number of the best agents out there, including Claude Agent, Codex, OpenCode, and more recently Cursor. We built AI into our editor's foundation instead of bolting it on top."

The Agent Client Protocol, abbreviated ACP and documented at zed.dev/blog/bring-your-own-agent-to-zed, is the part of this story most worth attention. ACP defines an open contract for agent integration: any agent that implements the protocol can run inside Zed with the same foundational primitives as any other. The set of agents that have shipped ACP support at launch is broad (Anthropic's Claude Agent, OpenAI's Codex, the OpenCode project, and Cursor, which joined the protocol shortly before the 1.0 launch), and the protocol is positioned to grow with the agent ecosystem rather than against it. The contrast with the VSCode + Cursor / GitHub Copilot extension model is structural: in the VSCode pattern, each agent is a separate plugin layered on top of the editor; in the Zed pattern, each agent is a peer collaborator running through a shared protocol with shared primitives.

The collaborative-coding extension of this is the second project Zed has been advancing toward 1.0: DeltaDB, a CRDT-based synchronization engine that tracks every change at character-level granularity and is designed to let humans and AI agents share a single consistent view of the codebase as it evolves. Sobo's framing: "DeltaDB lets multiple humans and agents share a single, consistent view of the codebase as it evolves. DeltaDB will allow you to invite teammates into conversations with agents to review and evolve agentic code directly in the context from which it's generated." The CRDT lineage runs directly from Sobo and Scandurra's Teletype work at Atom, with the difference that the protocol's other end in 2026 is at least as likely to be an AI agent as another human developer.

The comparison table

The set of editors a 2026 engineering team realistically chooses between, with their respective primary positioning:

The columns are the ones that actually matter for a 2026 editor-selection decision. The rendering-substrate row is the one that determines what's possible at the foundation level; the AI-integration row is the one that determines what kind of work the editor can absorb without breaking; the collab row is the one that determines whether the editor scales from individual to team to agent-team usage. The other rows are knobs that adjust the experience within the chosen foundation.

The honest reading of the table is that Zed and Cursor occupy opposing corners of the AI-native quadrant. Cursor is the AI-first VSCode fork that inherited VSCode's plugin ecosystem and built the agent integration as the project's central feature on top of the Electron substrate. Zed is the AI-first rebuild-from-scratch that constructed its own GPU-rendering substrate and offered the agent integration as one of several foundational primitives. Both bets are coherent. They are not the same bet, and the choice between them depends on which trade-off matters more for the specific deployment.

Performance and adoption

The performance argument for the rebuild-from-scratch route is the one most easily corroborated against the HN testimony from working users. One commenter cited 900 MB of resident memory with nine concurrent open projects and full language-server support, against a comparable VSCode setup that struggles to keep one such project open in the same memory envelope. Other commenters cited startup latency, input-to-frame latency, and large-file responsiveness as the dimensions where the Rust + GPU + Tree-sitter pipeline produces measurable wins. The 1.0 announcement claims "hundreds of thousands of developers now rely on Zed to ship software each day," which is consistent with the public download statistics Zed has been publishing through its release notes.

The dimensions where Zed remains less mature than VSCode are also visible in the same HN thread: project-specific LSP configuration is harder than it needs to be (commenters cited PHP and Rails projects that surface noisy default LSP warnings); the diff-and-merge UI does not yet match VSCode's character-level resolution; and Zed's extension language being Rust raises the authoring bar relative to VSCode's TypeScript or Sublime's Python ecosystems. None of these are foundational issues, and Zed's weekly-release cadence is closing them in measurable increments, but they are the issues the 1.0 announcement understates and the HN thread surfaced as the residual rough edges.

The licensing and commercial posture

Zed ships the editor itself under GPL v3 with Apache 2.0 for certain components. The Zed Terms of Service that drew confused early reactions in the HN thread apply only to the hosted services Zed offers (collaborative editing, AI tab-completion, the Zed account substrate), and not to the editor source code. The misreading is, in 2026, a recurring failure mode for open-source-editor-plus-hosted-services dual-licensing models, and Zed is not the only project to have its ToS surface confused for an editor-source license. The Zed clarification was posted in the HN thread by commenters who actually read the agreement; the editorially-useful takeaway is that the open-source editor and the hosted services are separable products with separate licensing surfaces, and a buyer considering Zed for an engineering team should evaluate each surface against the team's compliance posture independently.

Zed for Business, launching alongside 1.0, is the commercial layer the editor source is licensed against. It offers centralized billing, role-based access controls, and team management (the standard enterprise feature set for a SaaS engineering tool), and is positioned as the path Zed expects engineering organizations to take when they roll the editor out beyond individual-developer use. The economic question of whether the Sequoia-backed commercial layer can fund the open-source editor's continued development at its current pace is the question every VC-backed dev-tools company eventually has to answer, and Zed is several years younger in that arc than VSCode was at its analogous milestone.

What 1.0 actually means

Zed's own framing of the 1.0 milestone is the right one to carry forward: "1.0 doesn't mean 'done'. It also doesn't mean 'perfect'. It means we've reached a tipping point where most developers can quickly feel at home in Zed. If you tried Zed a year or two ago and bounced because something was missing, 1.0 is our invitation to try again." The release cadence has been roughly weekly throughout the v0.x series and is expected to continue. The list of capabilities that remain on the roadmap (improvements to the merge-conflict view, finer-grained per-project LSP configuration, broader debugger language support, and the ongoing DeltaDB rollout) is the list of follow-up work the launch announcement is honest about not having closed.

Coda

The structural argument for Zed at 1.0 is the one the built like a video game framing is meant to communicate: building an editor at the GPU substrate level is what makes the next generation of features (multi-agent parallel editing, character-level real-time collab between humans and agents, edit predictions at keystroke granularity) operationally possible. The argument is not that VSCode and its forks cannot ship any of these features, but that they will be shipping each one at a higher operational cost and a lower performance ceiling than an editor that owns its rendering substrate end-to-end.

The 1.0 milestone is therefore best read as a settlement of a long-running architectural bet rather than as the launch of a finished product. The bet was that the rebuild from scratch would, after five years, produce an editor whose foundation could absorb the agent era without bending. The HN reception (the highest-engagement story in the current pipeline cache) suggests the bet is paying off at the level of the developer community's attention. Whether it pays off at the level of the engineering-team selection decision is the next twelve months' worth of testing.
