Cursor alternatives: coding agents with their own apps
Claude Code, Codex, OpenCode, Kimi Code and DeepSeek Harness as Cursor alternatives: which have desktop apps or editor extensions, and how to run several in Mirasim.


The short answer
Cursor is an AI editor with its own coding agent. If what you use most is the agent, the coding agents from the model companies now come with their own apps: Claude Code and Codex each have a desktop app and editor extensions, and OpenCode has desktop, terminal and phone apps. Mirasim runs these agents side by side in one window.
- Claude Code or Codex extension
- You want to keep VS Code and an agent inside it
- OpenCode
- You want open source and any model provider
- Codex
- You already pay for ChatGPT
- Mirasim
- You want several agents, and teammates, in one place

Moving over from Cursor
- Rules: Cursor reads AGENTS.md as well as .cursor/rules. Codex, Grok Build and Pi read AGENTS.md, and Claude Code can read it in place of a CLAUDE.md, so plain AGENTS.md rules carry over.
- Editor: Claude Code's and Codex's extensions install in VS Code, and Codex lists Cursor and Windsurf too, so you can try them without changing editors.
- Cloud work: if you used Cursor Cloud Agents, a Mirasim team space keeps sessions running after you close your laptop.
