Zed 1.0 Is Here: The Rust-Powered Editor Challenging VS Code and Cursor

Zed 1.0 Is Here: The Rust-Powered Editor Challenging VS Code and Cursor

For years, Visual Studio Code has become the near-default choice for developers. Built on Electron, VS Code represents the triumph of open source and plugin richness, covering nearly every language and framework. But this flexibility came with increased memory consumption and slower startup times. Add AI integration on top, and our editor increasingly becomes a heavier tool. At this exact moment, Zed, created by the makers of the Atom editor and written from scratch in Rust, has officially launched with version 1.0. In this article, we examine the technology behind Zed, its features, and its position against VS Code, Cursor, and OpenAI Codex.

What Is Zed and Who Built It?

Zed is developed by Zed Industries, founded by the creators of the Atom editor and the Tree-sitter parsing library. Under Nathan Sobo's leadership, the team started the project in 2021 and built a code editor entirely from scratch in Rust. The project currently has nearly 80,000 stars on GitHub and is developed as open source under the GPL license.

The biggest difference is that Zed is not built on web technologies like Electron. Instead, it offers GPU-accelerated rendering through a custom user interface framework called GPUI. Using Metal on macOS and DirectX on Windows, this architecture allows the editor to deliver a smooth experience at 120 frames per second. Memory usage ranges between 100 and 200 MB for typical projects, virtually eliminating the slowdown developers feel throughout the day.

Key Features in Zed 1.0

The 1.0 release announced on April 29, 2026, signals that the Zed team considers the project ready for general use. The team notes in their blog post: "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." Here are the standout features of this release:

Parallel Agents and ACP Support

Zed presents AI agents as a natural part of the editor. Through an open protocol called ACP (Agent Client Protocol), you can run different agents simultaneously, such as Claude Agent, Gemini CLI, OpenAI Codex, and OpenCode. These agents perform file editing, code navigation, and tool execution at native speed. You can manage agents running in parallel across multiple projects. This feature is a significant advantage for developers who use multiple AI models at the same time.

Edit Prediction and the Zeta2 Model

Zed offers an edit prediction feature using the Zeta2 language model, which is built on open source and open data. This feature predicts the continuation of your code and provides inline completions. Similar to GitHub Copilot, Zed hosts this model on its own infrastructure, adopting a privacy-focused approach. By default, your code does not go to Zed's servers; you can use your own API keys or run local models.

Real-Time Collaboration

Zed offers multiplayer collaboration as a natural part of its structure. You can invite teammates to the project via a link and share real-time cursor and selection information. Thanks to CRDT-based editing, multiple developers can work on the same file without conflicts. Built-in voice chat and screen sharing are also accessible from within the editor. Compared to VS Code's Live Share extension, this feature offers a much more fluid and native experience.

Debugger and Git Integration

With the 1.0 release, Zed has expanded its debugging support through the Debug Adapter Protocol (DAP). It offers native debugging capabilities in multiple languages. Git integration allows you to perform basic operations such as staging, committing, pulling, pushing, and viewing diffs directly from within the editor. The bookmarks feature was also added in this release and can be persisted across sessions.

Zed vs Visual Studio Code

VS Code dominates the market with over 50,000 extensions and Microsoft backing. However, Zed targets a different segment. Here is a head-to-head comparison:

Performance and Resource Consumption

Zed opens in 0.5 to 1 second on a cold start. VS Code typically starts in 2 to 5 seconds, and this duration can increase with loaded extensions. The difference in memory usage is even more pronounced: while Zed consumes between 100 and 200 MB, VS Code ranges from 400 to 800 MB. When working with large files, Zed's fluidity in scrolling and file switching is noticeable.

AI Integration

VS Code offers deep integration with GitHub Copilot. Copilot Agent Mode provides autonomous multi-file editing and terminal access. However, these features require a subscription of $10 to $39 per month. Zed presents AI integration as a natural part of its structure and can be used without additional cost through the bring-your-own-key (BYOK) option. OpenAI, Anthropic Claude, Google Gemini, and local Ollama models are directly supported.

Extension Ecosystem

VS Code is the undisputed leader in this area. With over 50,000 extensions, it offers support for almost every language, framework, and cloud service. Zed has approximately a thousand WASM-based extensions, and this number is growing every day. However, Zed has not yet reached sufficient coverage in niche areas such as Flutter, Unity, Salesforce, or cloud integrations like AWS Toolkit. If your workflow depends on specific VS Code extensions, the transition may take some time.

Remote Development

VS Code offers remote development capabilities through containers, SSH, WSL, and the web. Zed has recently added Remote Development support and can reuse SSH ControlMaster sessions. Dev Container support also works close to the reference implementation. However, VS Code's maturity and broad platform support in this area still remain a step ahead.

Zed vs Cursor

Cursor is one of the most popular tools of recent times as an AI-focused IDE built on VS Code. With over 1 million paying users and more than $2 billion in annual recurring revenue, Cursor maximizes the AI-focused development experience. So where does Zed stand against Cursor?

AI Maturity and Agent Experience

Cursor can work with cloud-based agents on isolated virtual machines and offers up to 10 parallel agents per user. With Cursor 3, the Agents Window and Design Mode have matured the AI-focused development experience considerably. Zed offers the flexibility to run different agents within the editor through the ACP protocol. However, the agent experience is not yet at Cursor's level. According to Builder.io's assessment, while Zed scores 3.5 in agent user experience, Cursor achieves the highest score in this area.

Speed and Resource Usage

This is where Zed wins most clearly. According to independent benchmarks, Zed is 5 times faster than Cursor in file opening speed. While Zed can open a 100,000-line monorepo in less than 1 second, Cursor takes approximately 4.5 seconds. Memory usage also ranges from 200 to 400 MB for Zed, while Cursor consumes between 500 and 800 MB.

Pricing and Flexibility

Zed offers 50 hosted AI prompts per month in its free tier. When you bring your own API key, no additional subscription payment is required. Cursor, on the other hand, charges $20 per month for Pro, $40 per user for Business, $60 for Pro+, and $200 for Ultra. Zed offers a much more flexible model in terms of cost. Especially for developers who already pay for Claude or Gemini API keys, Zed can be used completely free.

Memory and Context Management

Cursor has productized native memory management like Skills, and Windsurf has Memories. Zed is not yet at the same level in this area. However, thanks to strong MCP support, it is possible to close this gap by connecting external memory servers. This makes Zed technically capable in memory management, but configuring it is left to the user.

Zed vs OpenAI Codex

OpenAI Codex stands out as a command-line-based coding agent. This tool, which can be integrated into VS Code, can make project-wide changes with natural language commands. The relationship between Zed and Codex is somewhat different: thanks to the ACP protocol, Zed can run Codex directly inside the editor. So Codex can be used as a tool within Zed.

At this point, it is more accurate to evaluate the two tools as complementary rather than direct competitors. While Codex CLI offers a powerful terminal-focused agent experience, Zed presents the outputs of this agent in a fast and fluid editor. Zed's strength lies in its ability to combine different agents in the same environment. Being able to use Claude Code, Gemini CLI, and Codex in parallel in the same project is one of the features that makes Zed unique.

Who Is Zed Suitable For?

Zed may not be the right choice for every developer. However, it is quite appealing for users with the following profiles:

• Performance-sensitive developers: Those who prioritize fast editor opening, low memory consumption, and fluid scrolling.
• Users of multiple AI models: Those who switch between Claude, GPT, Gemini, and local models and want this flexibility within the editor.
• MCP server users: Those who want to control tool management and approval processes in detail.
• Terminal-based agent users: Those who mostly work in the terminal with Claude Code and Codex CLI but want edits to happen in a fast editor.
• Collaborative teams: Teams that do real-time code sharing and pair programming.

However, Zed is not yet fully ready for developers who need special frameworks such as Flutter and Unity, or cloud integrations like AWS Toolkit. Similarly, those who expect AI memory management to work out of the box may lean towards Cursor.

Conclusion: Is a New Era Beginning?

Zed 1.0 brings a fresh breath to the code editor market. Its GPU-accelerated structure written in Rust, its approach to AI integration with a focus on speed and privacy, and its unique position of bringing different agents together through open protocols make it a strong alternative alongside VS Code and Cursor. Although it is still behind VS Code in terms of extension ecosystem and behind Cursor in terms of AI maturity, it carves out a unique place for itself in performance and flexibility.

The team has a clear message for developers who tried Zed a year ago and gave up due to a missing feature: "Try again." The 1.0 release shows that the editor's capabilities are at their highest level ever and it is still getting more performant. The revitalization of competition in the developer tools market is in our favor as end users. We will continue to see faster, smarter, and more collaborative editors.

If you want to try Zed, you can download it for macOS, Linux, and Windows from zed.dev/download. You can access the source code from the GitHub repository. Which editor do you use? Are you considering switching to Zed? Do not forget to share your thoughts.
