UI-TARS Desktop: review, pricing, security and alternatives

What UI-TARS Desktop does

UI-TARS Desktop belongs to the computer use family: agents that see the screen and drive the keyboard and mouse of a computer or phone. On our grid it ranks #6 of the 17 projects of this family listed in the directory.

You use it from: desktop app and terminal (CLI). It can run on your own machine or server.

Who is UI-TARS Desktop for?

It is for people who want to automate desktop software with no API, by driving the screen as a person would. Typical tasks people give it:

• chain actions in legacy business software
• copy data from one application to another
• test a desktop application

It is a good candidate if you are comfortable in a terminal and your data must stay on your machines.

Access and human control

According to its documentation, UI-TARS Desktop can:

• control the screen, keyboard and mouse
• drive a web browser

We could not establish whether it asks for human approval before sensitive actions: test it first on an unimportant account or folder.

The code is free, under the Apache-2.0 licence.

Getting started with UI-TARS Desktop

1. Install it: the project ships as a Node.js package (install with npm, or run directly with npx). The exact command is in the repository README.
2. Create an API key with the model provider and put it in an environment variable, never in a shared or versioned file.
3. Give it a first playground with nothing at stake: a test folder, a secondary account or a throwaway project. Only open your real accounts once you have seen how it behaves.
4. Give it a short, checkable task, review the result and its action log, then raise the difficulty step by step.

Security: risk level

An agent that controls the computer has the same rights as you: run it in a dedicated virtual machine.

Points found for UI-TARS Desktop:

• Sensitive access: it can control the screen, keyboard and mouse, with no established default human approval.
• Outside content: it reads web pages or API responses, which may contain booby-trapped instructions (prompt injection).

Three habits: least privilege (minimal rights, dedicated keys), human approval for irreversible actions, a sandbox for code execution. The AI agent security check reviews your setup in a few minutes.

UI-TARS Desktop vs other computer use

GitHub stars of the best-rated open-source projects in the computer use family. Stars measure attention, not quality: a heavily promoted project collects them fast, a specialised tool will have few.

UI-TARS Desktop and other computer use at a glance

The 7 best-ranked agents in the same family, 7 of them open source. The score out of 100 only applies to open-source projects; for proprietary services we show the published entry price. A dash marks information the documentation does not state.

How we rated it

Score: 71/100, computed only from public, verifiable data, with no subjective testing or partnership:

• Adoption 31/40: 39,374 stars on a log scale (40 points from about 200,000).
• Activity 20/30: last commit less than a month ago, 1 release in six months, 42 commits in a year.
• Framework 20/30: licence, default human approval, self-hosting, model choice and documentation site.

The score does not say whether the agent will succeed at your tasks: it measures how solid the project is. The full grid is on the method page.
