Open-source repository with no plan amounts in the text read; running it needs the user's own LLM API key, and the README notes a minimum payment of $5 to unlock an OpenAI GPT-4o key. No charge fact is recorded, since that payment is an OpenAI account requirement, not an Open Interface price.
- Free allowance
Not separately confirmed. Check the current plan before relying on a free allowance.
- Best suited to
developers and researchers automating GUI tasks with LLMs, since Open Interface drives keyboard and mouse and checks screenshots to assess progress.; macOS, Windows and Linux users who want a local agent harness, since binaries cover all three and a Python script path is documented.; builders who want to swap LLM providers, since setup covers both OpenAI GPT-4o and Google Gemini keys.

What to know before choosing
Good fit
developers and researchers automating GUI tasks with LLMs, since Open Interface drives keyboard and mouse and checks screenshots to assess progress.; macOS, Windows and Linux users who want a local agent harness, since binaries cover all three and a Python script path is documented.; builders who want to swap LLM providers, since setup covers both OpenAI GPT-4o and Google Gemini keys.
Limits and trade-offs
users who will not grant Accessibility and Screen Recording permissions on macOS, since the README states both are needed to operate the keyboard and mouse and take progress screenshots.; users who want a hosted tool with no setup, since Open Interface needs a local install plus their own LLM API key.

A closer look at Open Interface
Open Interface is an open-source tool that lets large language models control a computer: it operates the keyboard and mouse, takes screenshots to assess progress, and works on macOS, Windows and Linux, either from a downloaded binary or as a Python script. It connects to LLMs such as OpenAI GPT-4o or Google Gemini through the user's own API key.
Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.
When to choose Open Interface
- developers and researchers automating GUI tasks with LLMs, since Open Interface drives keyboard and mouse and checks screenshots to assess progress.
- macOS, Windows and Linux users who want a local agent harness, since binaries cover all three and a Python script path is documented.
- builders who want to swap LLM providers, since setup covers both OpenAI GPT-4o and Google Gemini keys.
When to choose something else
- users who will not grant Accessibility and Screen Recording permissions on macOS, since the README states both are needed to operate the keyboard and mouse and take progress screenshots.
- users who want a hosted tool with no setup, since Open Interface needs a local install plus their own LLM API key.
A practical starting workflow
- Download the binary for macOS, Windows or Linux, or clone the repository and install the Python dependencies.
- Grant the needed permissions, such as Accessibility and Screen Recording access on macOS, and add an LLM API key in Settings.
- Give the assistant a task, let it operate the keyboard and mouse, and check its screenshot-based progress assessment.
Check before committing
- The README setup notes that OpenAI GPT-4o access needs a minimum payment of $5 to unlock the key; that is an OpenAI account requirement, not an Open Interface price, so no charge fact is recorded.
- macOS operation needs Accessibility access for keyboard and mouse control and Screen Recording access for screenshots, according to the setup text.
- The Linux binary is stated as tested on Ubuntu 20.04 and the Windows binary on Windows 10, so other versions are not covered by the text read.
