What It Is

Diffs is an AI-native code editor. Its positioning is not “a traditional IDE with a chat sidebar,” but rather a rethinking of how human developers collaborate with AI agents. The official site emphasizes that “review is the bottleneck, not writing,” so the product focuses on viewing and reviewing diffs after AI-generated code changes, and on making agents a first-class presence inside the editor environment.

Core Capabilities

Based on the publicly available copy, Diffs has three main capabilities. First, it is compatible with agents such as Claude Code, Codex, and OpenCode, with support for more agents also mentioned. Second, it offers what it calls the “best diff view,” aiming to improve the review workflow for AI-generated changes. Third, agents can run in local, worktree, and remote scenarios, making it suitable for different workflows such as local development, branch isolation, and remote execution. Its autocomplete also emphasizes steerable autocomplete, allowing developers to guide the AI with intent during completion rather than passively accepting suggestions.

Pricing and Openness

The current page only offers a waitlist signup. It does not disclose pricing for a free tier, subscription plan, team plan, or enterprise plan, nor does it explain payment methods. There is also no clear information on whether the product is open source or closed source, whether it can be self-hosted, which operating systems it supports, its editor extension mechanism, or any API/SDK. Although it mentions that agents can run locally, in worktrees, or remotely, that does not mean the product supports private deployment.

Pros and Cons

The main advantage is that its positioning closely matches a real pain point in the AI coding era: generating code is becoming easier, but reviewing, understanding, and controlling changes remains difficult. Instead of putting AI in a chat window, Diffs integrates agents into the editor and diff workflow, which is a sensible direction. The downside is that there is still too little information available, and it currently feels more like an early preview page. Without documentation or details on language/framework support, team collaboration, security and compliance, and stability, it is hard to judge whether it is ready for real production use.

Who It’s For and Access from China

Diffs is better suited to individual developers or small teams already using AI coding agents such as Claude Code, Codex, or OpenCode, and who want to improve the efficiency of diff review. Access from mainland China, account registration, and payment availability are not mentioned in the public copy, so they remain unknown. If the product depends on overseas large model services, actual usage may be affected by network conditions and model account restrictions. Alternatives worth watching include Cursor, Windsurf, VS Code + GitHub Copilot, Zed, JetBrains AI Assistant, and Continue.
