Terminal coding agent
Install Freebuff globally with npm, change into a new or existing project, and start an agent from the terminal. The CLI requires Node.js 18 or later and supports macOS, Windows, and Linux.
Freebuff
Freemium
Freebuff is an ad-supported coding-agent suite for building and modifying software through the CLI, desktop app, web builder, or cloud workspace. It also includes an AI chat product for research and in-depth answers, with free access and optional paid plans.
Freebuffとは？
Freebuff is an ad-supported coding-agent suite for software development. It combines a terminal CLI, desktop application, prompt-based web app builder, GitHub-connected cloud IDE, and separate AI chat product. The core service is available without a subscription, API key, or credit card, subject to model allowances and other usage limits.
The products cover both new and existing projects. Freebuff Web starts an app from a prompt and provides managed hosting with a live URL, while Freebuff Cloud connects to a public or private GitHub repository and creates a cloud sandbox with an editor, terminal, real sandbox, and live preview. The CLI and Desktop products support local development, with Desktop allowing multiple agents to run in separate workspaces.
Freebuff’s free usage is funded by text ads. Users receive daily Freebucks to spend across supported models; the site notes that availability depends on country and VPN use, and that session and usage limits apply. Paid Starter, Plus, and Pro plans are also available, with plan allowances listed on the pricing page.
Freebuffでできること
Parallel desktop workspaces
Freebuff Desktop runs multiple coding agents in parallel on a computer, assigning each agent its own workspace. Installers are provided for macOS, Windows, and Linux, including platform-specific builds for Apple Silicon, Intel, Windows ARM64, older Windows CPUs, and Linux architectures.
Prompt-based web app builder
Freebuff Web is designed for starting a new app from a prompt. It includes fully managed agentic hosting and provides the resulting app on its own URL.
GitHub-connected cloud sandbox
Freebuff Cloud accepts public or private GitHub repositories, clones the selected project, boots a real cloud sandbox, and provides an automatically configured live preview. The workspace includes an editor, terminal, and sandbox.
Daily model allowance
Free users receive 100 Freebucks each day to allocate across available models. Allowances refill at midnight Pacific, do not carry over, and are affected by model availability, country, VPN use, and session limits.
AI research chat
Freebuff Chat is a separate AI chat experience for researching questions and producing answers that the site describes as deeply reasoned.
利用シーン
“Modify a local codebase from the terminal”
A developer can install the CLI, open an existing project, and describe a coding task without configuring a provider API key. This fits quick implementation, refactoring, or review work inside a familiar terminal workflow.
“Run independent coding tasks on a desktop”
A user working on several tasks can run agents in parallel, keeping each one in a separate workspace rather than mixing changes in a single working directory.
“Turn an idea into a hosted app”
Someone starting without an existing repository can use Freebuff Web to describe a new application, then work with the agent and access the hosted result through its app URL.
“Continue an existing GitHub project in the cloud”
A developer or team can connect a public or private repository, let Freebuff create a sandbox and live preview, and share the preview while working on the existing codebase. Projects exported or synced from other app builders can follow the same repository-based workflow.
“Research a technical or general question”
Users can use Freebuff Chat when they need an AI-assisted research and answer workflow rather than direct code changes in a repository.
よくある質問
Is Freebuff actually free?
The core Freebuff experience is offered free of charge and supported by text ads. Free usage is subject to daily model allowances, availability by country or VPN, and session or fair-use limits. Starter, Plus, and Pro paid plans are also available.
Do I need an API key or credit card?
The CLI and Desktop pages state that no API key or credit card is required to start. The CLI is installed with npm, and it requires Node.js 18 or later.
What is the difference between Freebuff Web and Freebuff Cloud?
Web starts a new app from a prompt and provides Freebuff-managed hosting. Cloud connects to an existing public or private GitHub repository, boots a cloud sandbox, and provides a live preview for that codebase.
Which operating systems support Freebuff Desktop and CLI?
Both products support macOS, Windows, and Linux. Desktop provides separate installers for several hardware and operating-system variants; the CLI runs through Node.js.
Can I use a private GitHub repository with Freebuff Cloud?
Yes. The Cloud page explicitly supports both public and private GitHub repositories. Freebuff clones the selected repository into a cloud sandbox and configures a preview.
