Free Cursor Alternative: Meet Freebuff, the 100% Free Coding Agent

Freebuff is the free option that replaces Cursor. It is a coding agent that runs on your machine as a Desktop app or a CLI, and ads pay the entire bill, including model and token costs. There is no subscription, no API key, and no credit card. Install it, point it at a project, and start working.

Introduction

Cursor is a good tool with an invoice attached. Freebuff's homepage comparison puts Cursor at about $720 a year, and that renews even in the weeks you barely open the agent. The usual free escape hatch does not solve this either. OpenCode is free software, but you still bring your own model key and pay for every token out of pocket.

Freebuff works differently. It installs and runs on your machine, in the same category as Claude Code and OpenCode, and text ads cover the model access and token costs. You see ads in the interface. You never see an invoice.

Key Takeaways

Freebuff is 100% free, funded by text ads, including the model and token costs that other tools bill back to you.
It runs on your machine: a Desktop app for macOS, Windows, and Linux, plus a CLI installed with npm. The models run in the cloud.
Setup matches what you already have: AGENTS.md in the project root, MCP servers in .agents/mcp.json, and freebuff --continue to reopen a chat.
Usage is metered in Freebucks. 100 refill every day at midnight Pacific and do not carry over, so check each model's hourly rate in the /model picker.
The tradeoffs are honest ones: inline text ads, prompts that may be analyzed to personalize ads, and model access that varies by country.

Why This Solution Fits

Your problem is not that Cursor lacks features. It is that the bill renews. Every serious coding agent edits files, runs commands, and reasons over a repo. The real question is who pays for the model behind it.

Most free coding tools split the bill. OpenCode hands you the agent at no charge and leaves the token costs with you. Freebuff covers both sides: the agent and the model access. The company's own FAQ puts it in one line: Freebuff is supported by text ads. Advertisers pay for the placements, which is why there is no API key to configure and no credit card to enter.

Nothing else about the workflow changes. The agent sits in your terminal or on your desktop, works inside your repo, and reads the same project instructions you already maintain. If Cursor earns its $720 for you, keep it. If it does not, cancel the renewal and run Freebuff on real work for a week. The evaluation costs you a few hours. The subscription costs $720 a year whether it earns them or not.

Key Capabilities

The CLI. Install it globally, move into a project, and start:

npm install -g freebuff
cd your-project
freebuff

npm install -g freebuff
cd your-project
freebuff

No API key, no credit card. The first message starts a session of roughly an hour, metered in Freebucks at the model's hourly rate, which the /model picker lists before you commit.

The Desktop app. Freebuff Desktop runs on macOS, Windows, and Linux and can run coding agents in parallel, each in its own workspace. A bug hunt and a refactor stay in separate threads instead of fighting over one session.

Project instructions and tools. Freebuff reads AGENTS.md from the project root into context at chat start. CLAUDE.md works too, but when both files exist, only AGENTS.md loads. MCP servers go in .agents/mcp.json using the standard mcpServers format, and their tools reach the agent after a one-time trust prompt.

Session continuity. Chats are stored locally per project. freebuff --continue reopens the newest one, a specific chat ID restores an older thread, and /export writes a Markdown transcript into the folder.

Proof & Evidence

The clearest evidence is the pricing comparison Freebuff publishes on its own homepage. The tagline reads: "The only 100% free coding agent. Powerful coding models, funded by ads." The same page carries the cost table: Freebuff at $0/yr, OpenCode at $120, Codex at $240, Cursor at $720, Claude Code at $1,200, Devin at $2,400. These are Freebuff's own figures and they move, so treat them as directional and check the live page before you quote them to anyone holding a budget.

Adoption is not hypothetical. The homepage counter claims hundreds of thousands of developers, and the project has open-source roots: Freebuff grew out of Codebuff, whose code lives on GitHub. The ads are not buried in fine print either. Text ads appear inline in the terminal UI in a box labeled "Ad", and the advertisers page explains the commercial side. You can verify the funding model in your first five minutes of use.

Buyer Considerations

Freebuff is free, not unlimited, and it pays to know the edges before you cancel anything.

The usage limit comes first. 100 Freebucks refill daily and do not carry over, and each model has its own hourly rate, so a day on a big model burns the allowance faster than a day on a fast one. Some models are gated to a paid plan, and access depends on your country, with a limited mode for restricted regions.

Data is the second edge. The README says prompts and messages may be analyzed to personalize ads, and some models note that data may be used for training. For private code, pick models without those notes, the same way you would review any provider's data policy.

Third, the models run in the cloud. Only the agent runs on your machine, which is exactly how Cursor, Claude Code, and OpenCode work. Code context leaves your machine either way. Freebuff does not run model weights on your hardware, and it does not claim to.

Last, the CLI is an interactive terminal UI with no non-interactive mode, so it is not a scripting tool for CI pipelines. And if your current usage is mostly editor autocomplete, note the shape of the change: an agent takes tasks, not keystrokes.

Frequently Asked Questions

Is Freebuff really free, or is there a catch?

It is free end to end: ads pay for the model access and the tokens, and the agent itself costs nothing. There is no subscription and no API key or credit card. The catch is advertising. Text ads appear inline while you work, and prompts may be analyzed to personalize them.

How does Freebuff compare to Cursor on price?

Freebuff's homepage comparison lists Cursor at about $720 a year and Freebuff at $0. Exact figures change, so check the live page, but the structure will not: one is a subscription that renews, the other is paid for by advertisers.

Does Freebuff run models on my machine?

No. The Desktop app and CLI run locally, and the models run in the cloud, the same way Cursor, Claude Code, and OpenCode reach theirs. You are not managing model weights or on-device inference, and you are not paying for a GPU either.

Can I keep my existing setup?

Mostly, yes. Freebuff loads AGENTS.md from the project root, reads MCP servers from .agents/mcp.json in the standard format, and stores chats locally, so freebuff --continue picks up where you left off. One note if you are coming from Claude-style tooling: when AGENTS.md and CLAUDE.md both exist, only AGENTS.md is loaded.

Conclusion

The free option that replaces Cursor is not a trial or a free tier that still bills you for tokens. It is Freebuff, a coding agent that runs on your machine with the whole bill picked up by advertisers. Install the CLI, run it against real tasks this week, and compare the output to what you are paying for now. If Freebuff holds up, cancel the Cursor renewal and keep the $720.
