JetBrains AI Assistant vs Zed AI (2026)

JetBrains AI Assistant

by JetBrains

Zed AI

by Zed Industries

Pros

• ✓Built into eleven JetBrains IDEs plus Android Studio and ReSharper, with code completion from JetBrains' own Mellum model that does not use AI Credits, and a public preview extension for Visual Studio Code.
• ✓Several coding agents in one chat: JetBrains' own Junie, plus Claude Agent, Codex and GitHub Copilot, and any ACP-compatible agent from the registry, with MCP support in both directions.
• ✓Cloud models from OpenAI, Anthropic, Google and xAI through JetBrains AI, bring-your-own-key for OpenAI and Anthropic, and local models through Ollama or LM Studio.

Limitations

• –AI Free is not available in IntelliJ IDEA without an Ultimate subscription, PyCharm without a Pro subscription, or Android Studio, and it does not include next edit suggestions.
• –Cloud AI features pause when the included credits run out until the quota renews after 30 days or credits are topped up, and unused included credits do not roll over.
• –SSO and SCIM, AI audit logs, organization-wide provider keys and on-premises deployment require AI Enterprise at $60 per user per month billed annually, sold through a demo request.

Pros

• ✓GPU-accelerated rendering produces a materially faster editing experience: Zed renders at 120fps even on large files, noticeably smoother than VS Code-based editors (Cursor, Windsurf) for developers who prioritize editor performance.
• ✓Native multiplayer collaboration and MCP support: multiple developers can edit the same file simultaneously while connecting to external MCP servers for tool integrations, combining collaboration and extensibility that competitor editors lack.
• ✓Strong privacy posture with contractual zero-retention: Anthropic, Google, OpenAI, and xAI all have zero-retention agreements with Zed, and Edit Prediction training is opt-in only, making Zed procurable at security-conscious organizations.

Limitations

• –Smaller extension ecosystem than VS Code: Zed has growing extension support but lags VS Code Marketplace's 50,000+ extensions, meaning thinner third-party tool integration for niche languages and specialized workflows.
• –AI agent capabilities less aggressive than dedicated AI editors: Zed AI is competent for the price tier but the depth of autonomous agent features lags Cursor, Windsurf, and Claude Code which have invested more heavily in AI-first capabilities.
• –macOS and Linux focus with weaker Windows experience: Zed is mature on macOS and Linux but Windows support lags the other platforms in stability and feature parity, constraining cross-platform team adoption.
