00:00:00When your editor feels slow, is it actually the code base or the editor?
00:00:03Recently, one name keeps popping up everywhere.
00:00:06This is Zedd.
00:00:07A Rust native editor that's crazy fast and it's going straight at Cursor's two biggest pain points.
00:00:12Lag on big projects and the fact that Cursor is still mostly a solo editor.
00:00:17Zedd didn't ship more AI, it shipped clawed integration and real-time multiplayer
00:00:21without turning the editor into a mess.
00:00:24We have videos coming out all the time, be sure to subscribe.
00:00:30Over the last few weeks Zedd quietly made some huge updates.
00:00:35The headline is clawed integration via ACP, the Agent-Client Protocol, which gives for
00:00:40better reasoning, cleaner reviews, and even custom agents without the editor feeling heavy.
00:00:45And that matters because a lot of AI editors do the opposite.
00:00:48They add features and then things start to feel slow.
00:00:51Zedd angles is different.
00:00:53This is not AI everywhere all the time, like Cursor.
00:00:56In fact, AI is optional.
00:00:58Zedd is all about speed and I felt the difference right out of the box.
00:01:02It's written in Rust with no electron and no browser pretending just to be an editor.
00:01:06On large repos like genuinely large, 100k+ line code bases, there is no lag.
00:01:12Like here on this major JSON file, it handles way better.
00:01:16Smoother scrolling and updating is a win here.
00:01:19Where Cursor can start to feel slow as the project grows, Zedd didn't seem to care.
00:01:23Now let's see if this holds up with actual use and look at some of the things I noticed.
00:01:28I'll keep this part simple.
00:01:29What it is, why it matters, and some quick examples.
00:01:33Now I'm going to demo the navigation, alright.
00:01:35It's super minimalistic, which took me a second, but I quite liked the feel here.
00:01:39If I first hit Command+P, this is file search.
00:01:43It's basically what we do all day, but now it's right here in front of us.
00:01:47Here's a bigger repo, and now results pop up instantly without much delay.
00:01:52If we go with Command+Shift+O, we get symbol search, which is something I really like.
00:01:57I'm not scrolling around hunting for functions or classes.
00:02:00It shows everything right here in the sidebar.
00:02:04With Command+Shift+F, I get repo-wide search.
00:02:07This is huge because big repos are where certain other editors start to fall apart.
00:02:12Zedd indexes fast, results update instantly, and it doesn't break when the code base gets
00:02:16too big.
00:02:17Now, I get it.
00:02:18Okay, great.
00:02:19These are a few basic tricks.
00:02:21Is that the only difference here?
00:02:22No.
00:02:23It only gets better from here.
00:02:24Now, on to AI, adding AI is optional, unlike Kersey, which is like heavy AI first.
00:02:30Check this.
00:02:31I can go highlight some code, press Control+Enter.
00:02:34Claude kicks in with a focused suggestion like adding error handling or refactoring a function
00:02:39right where I'm at in my code.
00:02:41A really nice touch is if I ask it to add something, it's going to drop it in right exactly where
00:02:47I told it to.
00:02:48What I like here is what doesn't happen.
00:02:50No constant pop-ups or extra UI stuff to clutter up my page, so the point isn't look how much
00:02:56AI it has.
00:02:58The point is it helps, and then it gets out of its way.
00:03:01Yes, you can still access the sidebar AI editor if you turn on Claude code with a simple Command+Shift+A,
00:03:08and you get something that feels familiar, kind of like cursor.
00:03:11So it's there if you want it, otherwise it's not.
00:03:14Now, the part cursor can't really match is collaboration.
00:03:17Zedd has something called channels.
00:03:20This is actually an insane feature.
00:03:22I want you to think like Slack or Discord, but integrated right into the editor.
00:03:27If I open that up with Command+Shift+C, I can create my own channel, invite teammates
00:03:32straight from GitHub, and share the project.
00:03:34And this is that boom moment.
00:03:37You get real-time cursors and avatars, live edits with everyone in the same place.
00:03:42It's almost like Google Docs, but for code without all that slowness.
00:03:46You can pair program, review changes, or debug together right inside the editor.
00:03:50The crazy part here is you can actually do live audio chat with everyone who's in your
00:03:55project, just like Discord or Slack, as well as having these channels.
00:04:00So to nail the contrast points here, if you care about performance on big projects, Zedd
00:04:05is directly aiming at cursor's biggest weakness, lag.
00:04:09It's native performance, GPU accelerated rendering, low overhead, and instant feedback.
00:04:14And the second point is just as important, if not more so, collaboration.
00:04:19It's multiplayer by design.
00:04:21Cursor for all its strengths still assumes you're working alone, and that means external
00:04:25tools for pairing, reviews, and walkthroughs.
00:04:29So the trade-off is basically this.
00:04:31Do you want an editor that's built around solo AI workflow, or do you want one that balances
00:04:35light AI with real-time multiplayer and collaboration?
00:04:39If you're tired of slowdowns and heavy repos, or you work with a team, Zedd's combo is actually
00:04:44a pretty compelling reason to give it a shot.
00:04:47It's not trying to replace your flow, it's just trying to keep up with it.
00:04:51So is Zedd enough to pull you away from cursor here in 2026?
00:04:55If speed matters, if large repos are your daily reality, or if you want real collaboration
00:04:59inside your editor, it just might be.
00:05:02Try it out, see how it feels in your workflow.

Key Takeaway

Zed is a high-performance, Rust-native code editor designed to solve the lag and collaboration limitations of AI-first editors like Cursor through GPU acceleration and built-in multiplayer capabilities.

Highlights

Zed is a high-performance code editor written natively in Rust, avoiding the overhead of Electron or browser-based shells.

The editor features deep integration with Claude AI via the Agent-Client Protocol (ACP) for enhanced reasoning without UI clutter.

Performance remains stable even on massive repositories with over 100,000 lines of code, offering lag-free scrolling and indexing.

Innovative 'Multiplayer' features allow real-time collaboration with shared cursors, avatars, and built-in audio chat.

Zed prioritizes a minimalistic design where AI is an optional tool that 'gets out of the way' rather than being the central interface.

Key navigation features like file search, symbol search, and repo-wide search are GPU-accelerated for instant results.

Timeline

Introduction to Zed and the Performance Problem

The video opens by questioning whether slow editing experiences are caused by the codebase or the editor itself. The speaker introduces Zed as a Rust-native solution specifically designed to address performance bottlenecks found in editors like Cursor. Key pain points identified include lag on large projects and the isolation of solo-editing workflows. Zed is positioned as a fast alternative that prioritizes Claude integration and real-time multiplayer features. This section sets the stage for a comparison between heavy AI-first interfaces and streamlined native performance.

Technical Foundation and AI Strategy

The speaker details Zed's recent updates, specifically the Claude integration via the Agent-Client Protocol (ACP) which enables cleaner code reviews and custom agents. Unlike many competitors, Zed treats AI as an optional feature to ensure the editor remains lightweight and responsive. The core technical advantage is its Rust architecture, which eliminates the lag associated with Electron-based applications. On repositories exceeding 100,000 lines, Zed maintains smooth scrolling and instant updates, even when handling large JSON files. This technical efficiency is the primary differentiator for developers working on industrial-scale projects.

Minimalistic Navigation and Fast Search

This segment provides a demo of Zed's minimalistic navigation system, which the speaker describes as surprisingly intuitive. Use of Command+P for file search shows results popping up instantly without the typical indexing delay seen in other tools. Symbol search via Command+Shift+O allows for quick jumps to functions or classes through a dedicated sidebar. Repo-wide search is highlighted as a critical feature for large-scale development where other editors often struggle to keep up. These tools are designed to stay out of the way while providing high-speed access to the codebase.

Optional AI Integration and Workflow

The speaker contrasts Zed's 'AI as a tool' philosophy with the 'AI everywhere' approach of Cursor. Users can trigger Claude for focused refactoring or error handling by simply highlighting code and pressing Control+Enter. This allows for seamless code insertion exactly where requested without intrusive pop-ups or cluttered UI elements. For those who prefer a more traditional AI interface, a sidebar editor can be toggled using Command+Shift+A. This section emphasizes the flexibility of choosing when and how to interact with artificial intelligence during development.

Multiplayer Collaboration and Channels

One of Zed's most unique features is its native collaboration system called 'Channels,' which functions like a built-in Slack or Discord. Developers can invite teammates directly from GitHub to participate in real-time 'multiplayer' coding sessions. This includes shared cursors, live avatars, and the ability to perform audio chat without leaving the editor. The experience is compared to Google Docs but optimized for the performance demands of software engineering. This setup effectively eliminates the need for external screensharing or third-party pairing tools.

Final Comparison and Verdict

The final section summarizes the competition between Zed and Cursor by highlighting the trade-offs between solo AI workflows and high-performance collaboration. Zed's primary strengths are its GPU-accelerated rendering, low overhead, and multiplayer-by-design architecture. The speaker suggests that for teams or individuals dealing with heavy repositories, Zed offers a compelling reason to switch. It is framed as an editor that doesn't try to replace the developer's flow but rather keeps up with it at any scale. The video concludes by inviting viewers to test the editor's speed in their own professional environments.
