Zed is a new code editor built for speed and optimized for working with large codebases and AI-powered tools. It boasts significantly faster performance than VS Code, especially when handling massive files and complex language servers. Built on a custom, from-scratch foundation, Zed uses Rust for the backend and a novel tree-sitter based approach for syntax highlighting, enabling near-instantaneous loading and interaction. The editor also prioritizes collaborative editing with built-in real-time co-editing capabilities and aims to integrate tightly with AI coding assistants in the future.
ArkFlow is a high-performance stream processing engine written in Rust, designed for building robust and scalable data pipelines. It leverages asynchronous programming and a modular architecture to offer flexible and efficient processing of data streams. Key features include a declarative DSL for defining processing logic, native support for various data formats like JSON and Protobuf, built-in fault tolerance mechanisms, and seamless integration with other Rust ecosystems. ArkFlow aims to provide a powerful and user-friendly framework for developing real-time data applications.
Hacker News users discussed ArkFlow's performance claims, questioning the benchmarks and methodology used. Several commenters expressed skepticism about the purported advantages over Apache Flink, requesting more detailed comparisons, particularly around fault tolerance and state management. Some questioned the practical applications and target use cases for ArkFlow, while others pointed out potential issues with the project's immaturity and limited documentation. The use of Rust was generally seen as a positive, though concerns were raised about its learning curve impacting adoption. A few commenters showed interest in the project's potential, requesting further information about its architecture and roadmap. Overall, the discussion highlighted a cautious optimism tempered by a desire for more concrete evidence to support ArkFlow's performance claims and a clearer understanding of its niche.

Hacker News users discussed Zed's performance claims, with some expressing skepticism about its "fastest" claim, especially regarding scrolling and syntax highlighting compared to established editors like Sublime Text and VS Code. Others pointed out the lack of clear metrics backing up the speed claims, emphasizing the importance of quantifiable data for such comparisons. Several commenters showed interest in the editor's potential, especially its use of Rust and its novel approach to collaborative editing. However, some found the comparison to VS Code unfair, given VS Code's extensibility and vast plugin ecosystem, which contributes to its performance overhead. The closed-source nature of Zed also drew concern, with users preferring open-source alternatives for customization and community involvement. Finally, some questioned the focus on AI features, suggesting they might be premature or unnecessary for core editing tasks.
The Hacker News post titled "Zed: High-performance AI Code Editor" (https://news.ycombinator.com/item?id=43912844) has generated a moderate number of comments, many of which express cautious optimism or skepticism about Zed's performance claims and overall value proposition.
Several commenters focus on the claim of Zed being the "fastest" AI code editor. Some question the methodology behind this claim, requesting benchmarks or comparisons against other editors like VS Code. Others point out that "fastest" can be subjective and depend on specific use cases and hardware. One commenter suggests that raw speed might not be the most crucial factor for an AI code editor, arguing that the quality of code suggestions and overall user experience are more important.
Another recurring theme in the comments is Zed's closed-source nature. Many users express concern about relying on a proprietary tool for critical tasks like coding, emphasizing the benefits of open-source alternatives. Some speculate about potential vendor lock-in and the possibility of Zed introducing paid features in the future. There is a discussion about the trade-offs between closed-source development potentially allowing for faster iteration and innovation versus the transparency and community involvement fostered by open-source projects.
Several commenters discuss Zed's features, particularly the AI assistance capabilities. Some express interest in trying these features, while others remain skeptical of their practical usefulness. There's a discussion about the potential for AI to truly enhance the coding experience, with some suggesting that current AI coding tools are more gimmicky than genuinely helpful. One commenter expresses a desire for more concrete examples and demonstrations of Zed's AI features in action.
A few comments touch upon Zed's choice of using Rust and its potential impact on performance. One commenter questions the necessity of using Rust for the entire application, suggesting that a hybrid approach might be more efficient.
Finally, several commenters mention existing alternatives, such as VS Code with extensions, and question whether Zed offers enough differentiation to justify switching. There's a general sentiment that Zed needs to demonstrate a significant advantage over established players to gain widespread adoption.
