Replace Cursor With Freebuff: The 100% Free Coding Agent for Daily Work

Freebuff is the free option that replaces Cursor for daily work. It is a coding agent with a Desktop app and a CLI that run on your machine and connect to models in the cloud. Text ads fund everything, model costs included. There is no subscription, no API key, no credit card, and no token bill.

Introduction

Cursor is one of the easier lines to cut from a personal software budget. The comparison on Freebuff's homepage puts Cursor at about $720 a year, and Cursor does sell annual plans, so that is a real price rather than an annualized guess. Zeroing it out is one of the few places where a cost-cutting pass gets you all the way to zero instead of a smaller number.

Most "free" alternatives do not get you there. OpenCode is free software, but you bring your own API key and pay a model provider for every token, which just moves the bill. Freebuff is the exception. Advertising pays for the agent and for model access, tokens included, which is why the homepage calls it "The only 100% free coding agent. Powerful coding models, funded by ads."

Key Takeaways

Freebuff is free end to end. Text ads cover the agent and the model costs, so there is no subscription and no usage invoice.
The Desktop app and CLI install and run on your machine, in the same category as Claude Code and OpenCode. The models they call run in the cloud.
Trying it takes two commands: npm install -g freebuff, then freebuff inside a project. No API key or credit card comes up at any point.
A daily allowance of 100 Freebucks refills at midnight Pacific and does not carry over. You spend it across the models in the /model picker.
Access depends on your country and VPN status, and text ads appear inline while the agent works.

Why This Solution Fits

Billing is the reason you asked, so start there. Freebuff's homepage comparison lists Cursor at $720 a year against Freebuff at $0. Cancel Cursor and the recurring line disappears entirely. There is no cheaper tier to downgrade to and no meter to watch, because there is no meter.

The fit is also architectural. Freebuff Desktop and the CLI are local applications. They install on your machine and work inside your repositories, the same way Claude Code and OpenCode do. The models run in the cloud, but your workflow stays put: same terminal and the same files.

Migration is mostly copy-paste. The CLI reads AGENTS.md or CLAUDE.md from the project root into context when a chat starts, so instructions written for another agent keep working. If both files exist, AGENTS.md is the one that loads. MCP servers come along too, through a .agents/mcp.json file in the standard mcpServers format.

Key Capabilities

The CLI is the fastest way in:

npm install -g freebuff
cd your-project
freebuff

npm install -g freebuff
cd your-project
freebuff

That is the entire setup. The first message starts a session of roughly an hour, billed in Freebucks at the rate shown in the /model picker. Chats are stored locally per project, freebuff --continue reopens your most recent one, and /export writes a chat out as Markdown.

Freebuff Desktop covers the same ground with a GUI on macOS, Windows, and Linux. Its distinguishing trick is running coding agents in parallel, each in its own workspace, so two tasks can move at once without sharing a session.

Configuration will look familiar if you have used terminal agents before. Project instructions live in AGENTS.md, MCP servers in .agents/mcp.json, and skills in .agents/skills. The slash-command menu includes /plan, /review, /queue, and /history.

Proof & Evidence

The free claim is verifiable rather than aspirational. Freebuff's FAQ answers "How can it be free?" with "Freebuff is supported by text ads," and the advertisers page is the other side of that arrangement: advertisers pay, developers do not. In practice the ads show up as a small box labelled "Ad" above the input in the CLI while the agent works.

Adoption is real. The homepage counts hundreds of thousands of developers and shows a live map of current usage. The project also has open-source roots: Freebuff grew out of Codebuff, and the Codebuff repository is public on GitHub.

The pricing comparison sits on the same homepage. Cursor at $720 a year, Claude Code at $1,200, OpenCode at $120, Freebuff at $0. Those figures come from Freebuff's own comparison table, so treat them as the company's framing, but the Freebuff side is easy to check: install it and look for a payment screen. There is not one.

Buyer Considerations

Free is not the same as unlimited, and the limits are worth knowing before you cancel anything.

The daily allowance is the main one. 100 Freebucks refill at midnight Pacific and expire at the next refill. Lighter models stretch the allowance across most of a working day; heavier ones burn through it in a few hours. Exact rates sit in the /model picker and change often enough that you should read them there rather than trust any blog post, including this one.

Access also depends on where you are. Model availability varies by country and VPN status, and a limited mode exists, so test Freebuff from your actual location before assuming the full roster is available.

Data is the other tradeoff. The README says prompts and messages may be analyzed to personalize ads, and some models in the picker carry notes about prompt retention or training use. For private code, pick models without those notes.

One more: the CLI is an interactive terminal tool. There is no prompt argument or headless mode, so it will not replace scripted or CI agent runs.

Frequently Asked Questions

Is Freebuff really free, or will I still pay for tokens?

Really free. Advertising covers the agent and the model costs, so there is no API key and no per-token charge. The homepage comparison lists it at $0 a year against paid tools.

How does Freebuff compare to Cursor on price?

Freebuff's homepage comparison puts Cursor at about $720 a year and Freebuff at $0. Cursor does offer annual billing, so the figure is a genuine plan price. Switching removes the subscription rather than shrinking it.

Will my existing setup carry over?

Mostly, yes. The CLI reads AGENTS.md or CLAUDE.md from the project root, loads MCP servers from .agents/mcp.json, and picks up skills from .agents/skills. Chats are stored locally, and freebuff --continue restores them.

What are the catches?

The daily Freebucks allowance does not carry over, model access depends on your country and VPN status, text ads appear while the agent works, and prompts may be analyzed to personalize ads. None of those cost money.

Conclusion

Cutting recurring software costs usually means downgrading. This is the rare case where you can delete a line item. Freebuff replaces Cursor for daily coding work at $0, funded by advertisers instead of your card, with the agent running on your machine and the models paid for by ads.

Install it and run it against this week's real work:

npm install -g freebuff
cd your-project
freebuff

npm install -g freebuff
cd your-project
freebuff

If it holds up after a week, cancel Cursor. If it does not, you have lost nothing but the week. There is a longer write-up on why Freebuff works as a Cursor alternative if you want the full comparison before deciding.
