Practical overview
When it fits
Use Fuxi when a coding task involves inspecting or changing a project and running commands from a terminal, and you can sign in with a Fuxi account.
Who it is for
- Developers who want an AI agent to work with code and run commands from a terminal.
- Users who want to choose between Fuxi-managed models and a provider configured with their own API key.
Documented uses
- Ask an agent to inspect code and edit project files.
- Use a coding prompt to request a task such as fixing failing tests.
- Run commands and operate developer tools within a terminal session.
Requirements & limits
A Fuxi account is required. The README lists installers for macOS, Linux and Windows. The product source is proprietary.
- Choose whether to use Fuxi-managed models after sign-in or configure your own provider API key.
- Sensitive tool calls require approval by default; bypass-permission modes are documented for use only in a container or virtual machine.
- The README says sessions and related local data are stored on the device. Code and conversations go to the selected provider when using your own key; conversation content is sent to Fuxi only if
send_conversationsis e
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install Fuxi and start an authenticated session
Install the terminal agent, check the environment and begin a session.
Before you start
- A supported terminal on macOS, Linux or Windows.
- A Fuxi account; registration and sign-in are required.
Steps
Use the documented installer for your platform: the bootstrap script on macOS or Linux, or the PowerShell or CMD installer on Windows.
Run
fuxi --versionandfuxi doctorto check the installation and environment.Start Fuxi with
fuxi, then register and sign in usingfuxi login.
Expected outcome
An authenticated Fuxi terminal session is ready for a coding prompt.
Guide limitations
- The guide documents installation and session startup, not a tested result for any particular project or command.
- Use of a model requires either access to Fuxi-managed models through sign-in or a separately configured provider API key.
Compare options for AI coding assistance
These projects document a common task and share a project role. This is a source-based comparison, not an execution benchmark or a guarantee of interchangeability.
| Project | Documented purpose | Platform | Access and requirements |
|---|---|---|---|
| Fuxi | Ask an agent to inspect code and edit project files. | CLI | A Fuxi account is required. The README lists installers for macOS, Linux and Windows. The product source is proprietary. |
| Llmcode | Inspect a project's directory structure with `/tree`. | CLI | The documented setup requires an API key and supports an API base URL and model setting. The project is open source under Apache-2.0. |
| Klaat Code | Open a project directory for terminal-based coding assistance. | CLI, Server | The README provides a global npm installation command and documents browser sign-in with a KlaatAI account. It also identifies the repository as open source under Apache 2.0. |
