The Cursor alternative for agent work

The short answer

Switch your agent work to OmniRush. You keep whatever editor you like, and the agent work stops costing money: GPT 6 Astra, GPT 6.1 Sol and GPT 6 Sol come with a daily allowance that refills every day, with no card and no paid tier. You also get swarm agents, a Linux sandbox per project and a terminal CLI for scripts and CI.

What to look for in a Cursor alternative

• Frontier models without a second bill. On Cursor, GPT, Claude and Gemini sit outside the plan's pool and are paid at API list price on Premium and above.
• An agent that does the whole task: reads the code, runs the commands, checks its own work, and shows you the diff.
• A window and a terminal. A desktop app for day-to-day work, and a CLI for SSH, scripts and CI.
• Somewhere safe to run commands, so installs and experiments do not touch the rest of your machine.
• No lock-in: it should work on the folder you already have, beside the editor you already use.

OmniRush ticks every one of those, for free.

Cursor alternatives compared

For the details, see OmniRush vs Cursor, OmniRush vs Claude Code and OmniRush vs Windsurf. If you want an open-source terminal agent or another free tool, there is also OmniRush vs opencode and OmniRush vs Freebuff.

What you get with OmniRush

• Frontier models: GPT 6 Astra (the default), GPT 6.1 Sol and GPT 6 Sol, free with a daily allowance. Claude Opus 5.5, Claude Sonnet 5.5 and Kimi K3.1 Pro are available in OmniRush too, and they work in the same per-project sandbox as every other model. Usage limits apply, and a request may be served by an equivalent or newer model while OmniRush tests models or manages capacity, as the Terms say.
• A desktop app for Windows, macOS and Linux with swarm agents: ask for a swarm and several agents split one task side by side, then hand you one summary. It also has a code editor and an IDE layout beside the chat.
• A terminal CLI built on the opencode engine: an interactive agent, one-shot runs with -p, pipes, scripts, CI and SSH.
• A Linux sandbox per project, so the agent's installs and commands run apart from the rest of your machine, and installed packages are still there next time.
• Guarded by default: the agent asks before risky actions such as git writes, destructive commands and sudo. Careful mode asks before every change and command; Auto never asks.
• Built-in best-practice guides for setup, features, bugs, tests, refactors and reviews, and an agent that checks its own changes with your project's checks, sees code diagnostics after edits and keeps notes in AGENTS.md.
• Review, fix and undo built in: /review checks your changes, /fix fixes what it found, and one /undo takes back a whole turn while keeping your own edits.
• Hosted web search for the model, when it is available for your account, with the searches and their sources shown in the chat.
• MCP servers from a supported list: filesystem, git, SQLite, memory, sequential thinking, time, Playwright on local pages, and Figma with your own key.

How to switch

1. Create your account and connect your GitHub account.
2. Read the Terms and the Privacy Policy, which together are the data agreement, and accept them when you sign up.
3. Download the desktop app from the download section, or install the CLI with npm i -g omnirush@latest.
4. Open the project folder you use in Cursor and describe the task: the bug, the files involved, and how to check the fix.
5. Review the diff in the app's editor or your own, run your tests, and commit.
