Comparing as AI Pair Programming & Terminal AgentsZed vs Factory
Zed
Factory
Core Differences
The fundamental difference lies in their primary function and architectural approach. Zed is first and foremost a code editor—a direct replacement or alternative to tools like VS Code or Sublime Text. Its AI capabilities are deeply integrated within the editor to assist the human developer in writing and managing code more efficiently. It's about enhancing the individual's coding experience.
Factory, conversely, is an autonomous agent platform that orchestrates and executes full software development tasks independently of a specific IDE. It's not an editor but a system of Droid agents that act as an AI workforce, performing actions like writing code, running tests, and submitting pull requests across the entire SDLC. It's about automating the development workflow across a team or organization.

Editor's Take
Honest opinion from our review team
As an editor, I found Zed to be an absolute pleasure to use. The speed and responsiveness are genuinely noticeable; it feels incredibly snappy and lightweight, a refreshing change from more resource-heavy alternatives. The integrated AI features, particularly the edit predictions, felt like a natural extension of my thought process rather than an intrusive pop-up. The collaborative aspect is also remarkably seamless, making pair programming feel almost effortless. My main consideration would be the smaller extension ecosystem, which might mean a slight adjustment period for those coming from more established editors. However, the core experience is so polished that it quickly becomes a minor point.
Factory, on the other hand, offered a completely different 'feel.' It wasn't about the direct interaction with code, but rather the satisfaction of delegating complex engineering tasks. I found the concept of Droids autonomously tackling tickets, writing tests, and opening pull requests to be incredibly powerful. It felt like having an invisible, highly capable engineering team working in the background. The initial setup and integration into a team's workflow would require some effort, but the long-term potential for accelerating development cycles and offloading repetitive work is immense. It's less about the 'feel' of coding and more about the 'feel' of orchestrating a highly automated development pipeline.
Detailed Comparison
Zed offers a highly attractive Freemium model, particularly for developers who prefer to use their own AI model API keys. The Personal ($0 forever) plan is incredibly generous, including 2,000 accepted edit predictions per month and unlimited usage with your own API keys or external agents. This means developers can leverage powerful models like Claude Agent or Codex CLI without incurring any cost from Zed, making it an excellent value for those comfortable managing their own token consumption. The Pro ($10/month) tier offers unlimited predictions and a modest $5 of included tokens, with usage-based billing thereafter, which can add up quickly with heavy agentic use. The Business ($30/seat/month) tier focuses on organizational features but lacks a free trial, which might deter initial exploration.
Factory also employs a Freemium model, though its entry points are generally higher. The Pro ($20/month) tier is the starting point for individuals, offering access to its core Droid agent capabilities. Subsequent tiers like Plus ($100/month) and Max ($200/month) provide increased usage limits and features like Droid Computers, Factory-managed cloud sandboxes. For larger teams, Business and Enterprise tiers are custom-priced, offering advanced governance, deployment options (including on-premise), and dedicated support. While Factory provides powerful automation, its pricing structure means significant investment is often required to unlock its full potential, especially for teams. For individuals, Zed's free tier, especially with BYO API keys, offers superior immediate value for AI-assisted coding.

AI Verdict
In the rapidly evolving landscape of AI-assisted software development, Zed and Factory represent two distinct yet powerful approaches. Zed is a high-performance, GPU-accelerated code editor built from the ground up in Rust, designed for speed, low latency, and deep AI integration. Unlike traditional editors that bolt on AI as an afterthought, Zed treats agentic collaboration as a core feature. Its Parallel Agents allow developers to manage multiple AI threads simultaneously, while the Agentic Editing mode facilitates fluent delegation of coding tasks with live progress tracking. The editor's Zeta2 open-weight model provides fast, context-aware edit predictions, anticipating a developer's next move. Zed particularly shines for developers who prioritize a blazingly fast, responsive coding environment and seamless, integrated AI assistance directly within their primary workspace, especially for real-time collaborative coding sessions.
Conversely, Factory is an agent-native software development platform centered around autonomous Droid agents. These Droids are engineered to execute entire engineering tasks, moving far beyond mere code suggestions. They can read tickets, analyze codebases, run commands, edit files, write tests, and submit pull requests, effectively spanning the full software development lifecycle from triage to release. Factory distinguishes itself through its model-agnostic and interface-agnostic design, allowing teams to leverage various frontier and open-weight models (GPT-5, Claude Opus, Gemini) from their preferred interfaces—be it a desktop app, CLI, Slack, or web. Its Coordinator-Droid architecture orchestrates specialized agents for coding, review, documentation, and testing, making it ideal for teams seeking to automate significant portions of their development workflow and accelerate delivery cycles by offloading routine or complex tasks to intelligent agents.
Ultimately, while both leverage AI to enhance software development, their core strengths diverge significantly. Zed empowers the human developer with an exceptionally fast editor and intelligent co-pilot features, making their coding experience more efficient and collaborative. Factory, on the other hand, empowers the team by deploying autonomous agents to execute the development work, effectively creating an AI workforce that augments human capacity and streamlines the entire SDLC. The choice between them hinges on whether the priority is optimizing the individual developer's immediate coding environment or automating broader, end-to-end development processes.
Frequently Asked Questions
QIs Zed truly faster than established editors like VS Code or Sublime Text?
Yes, Zed is engineered for speed. Built in Rust with a custom GPU-accelerated UI framework (GPUI) rather than Electron, it boasts near-instant startup times, smooth 120fps rendering, and exceptionally low input latency, often outperforming web-based editors like VS Code in raw performance.
QHow does Factory's 'Droids' approach differ from standard AI code generation tools?
Factory's Droids go beyond simple code generation; they are autonomous agents designed to execute *full engineering tasks*. This includes reading documentation, running commands, editing multiple files, writing tests, and submitting pull requests, effectively spanning the entire software development lifecycle, whereas most code generation tools focus solely on suggesting or generating code snippets.
