Freebuff

What Freebuff is

Freebuff calls itself "the only 100% free coding agent", with "Powerful coding models, funded by ads." It is a family of 5 products rather than a single editor: Desktop, CLI, Web, Cloud and Chat, each tagged "New" on the home page. For this directory the one that matters most is Freebuff Web, which the site describes as a "100% free AI web app builder with fully managed agentic hosting" that takes you from prompt to a live app on its own URL. The others are coding agents for people who work in code, so the entry fits a developer or technical founder who wants an AI to do the building at no cost, and a non-developer who wants a hosted web app from a description. The home page invites you to "Join 550,640 developers", and a live map shows "1K+" developers building right now, with the top countries listed. A banner line at the foot of the home page sums up the company's attitude: "We just killed paid coding agents."

What you build and how

Freebuff Web is the builder. You describe an app and the agent generates it, hosts it, and gives it a URL. Freebuff's own blog says Freebuff Web comes "with auth/DB/deploy built in", lists authentication and a database as included, and gives a one-click GitHub eject, so the code can leave with you. The same post describes Web as a prompt-to-app loop with "no per-generation meter", and the Freebuff team's author note calls Web "the free way to ship full-stack apps" with "No subscription, no setup, no lock-in." For native mobile, the post says "Freebuff CLI + Expo gets you there in a few prompts", and marks mobile app generation as "Via Freebuff CLI + Expo" rather than a built-in feature of Web. The home page FAQ covers whether you need to know how to code to use Freebuff Web, whether you can deploy and host the app for free, and whether you can bring your own design or theme, which shows the questions the team expects from non-developers.

Freebuff CLI is "A 100% free coding agent, right from your terminal." The home page shows the whole setup as 3 commands: npm install -g freebuff, cd your-project, freebuff, with "No API key, no credit card. It just runs." The terminal screenshot shows the agent running on MiniMax M3 inside a project folder.

Freebuff Desktop runs on macOS, Windows and Linux and lets you "Run coding agents in parallel on your machine", "each in its own workspace." It also needs no API key and no credit card, and there is a separate "Build in your browser" route for anyone who would rather not install anything.

Freebuff Cloud is "A coding agent in a full cloud IDE, working on any GitHub repo", with an editor, a terminal and "a real sandbox". "Nothing to install." You connect GitHub, and it works on public or private repos. The sample session shows a request to add rate limiting to a checkout API in a storefront repository: the agent reads 34 files and maps the API routes, runs the test suite, and reports 3 files changed, with tabs for Preview, Code, Terminal and Changes, a Deploy button, and a sandbox running a dev server. That is the clearest picture on the site of what working with Freebuff looks like: you ask in plain language, the agent edits real files and tests them, and you review the diff.

Freebuff Chat is "A free AI chat that researches and thinks deeply to answer your questions", a general assistant beside the building tools.

So a reader coming from a prompt-to-app mindset starts with Web. A reader who wants to own a repository starts with Cloud or CLI, and a reader who wants several agents working at once on a laptop picks Desktop. All 5 products draw on the same daily allowance of models, which a post from the team on the home page confirms when it says a newly added model can be used "in any of our 5 products from coding agents to chat". There is no visual drag-and-drop editor on the site; this is a prompt-and-code product.

The evidence from the pages

Price. The home page says Freebuff is "$0 / yr" and "Freebuff is $0. Forever." The FAQ answers "How can it be free?" with "Freebuff is supported by text ads." The navigation carries an Advertisers link, which fits that model.

Daily allowance. Users get "100 Freebucks every day. Spend them on any mix of these models. No subscription required." The listed free hours per day by model are:

• Unlimited: Solar Mini 4 and Space Bunny Alpha
• 10 hours: MiMo 2.6 Flash and Solar Pro 4
• 6 hours: GLM 5.3 Flash and DeepSeek V4.1 Flash
• 5 hours: GPT-6 Luna
• 3 hours: MiMo 2.6 Pro

The page adds that "Hour totals use your whole daily allowance on one model; they aren't added together," that daily Freebucks "refill at midnight Pacific and don't carry over," that "Access depends on your country and VPN," and that "Session usage limits apply." Gemini 3.8 Flash and Muse Spark 1.3 are "included with a paid plan." GPT-6.1 Sol is "free in the US and included with a paid plan everywhere else", with one session a day for every account. The site does not say what a paid plan costs. The FAQ also mentions a limited mode, and the model chart marks each model as full access or limited access.

Social proof. The home page shows a testimonial, "Life-changing in making a dream of mine come true", credited to Mia Cova, and a row of video reviews by independent creators, among them a full test of the CLI, Desktop app, web builder and Cloud. Posts from James Grugett announce free access to DeepSeek V4 Flash, with 6 free hours a day "in every country", and to GPT 5.6 Luna.

Content and updates. A blog sorted into Comparisons, Guides, Community, Research, Engineering and Launches carries posts written by the Freebuff team, including a guide on leaving a paid cloud agent subscription while keeping the project on GitHub. The a0.dev post is dated May 22, 2026 and the Cloud posts July 7, 2026, so the product and its model list change often.

Who it suits and who it does not

Freebuff suits solo developers, students, side-project builders and small teams who are comfortable with code or with GitHub and want an AI agent without a subscription. The Web builder gives a founder a fast route to a hosted prototype with login and data already wired, and the one-click GitHub eject, as the company describes it, keeps the exit open. The CLI and Cloud agents suit people who already have a repository and want help inside it, and Desktop suits someone who wants to run several tasks side by side.

There are real caveats. The service is paid for by text ads, so you will see them. Free model hours are rationed by model, reset daily at midnight Pacific and depend on your country, so a long working day on one stronger model can run into limits. Several models are listed as paid-plan only or region-limited. With every product tagged "New", expect the line-up to keep moving.

It is a weaker fit for non-technical teams that want a visual builder with forms, roles and governed workflows, since Freebuff is built around prompts, code and repositories rather than a canvas.
