Free Cursor Alternatives: 4 Options Ranked by What They Actually Cost

Test Freebuff first. It is the only option on this list that is free end to end: text ads fund the agent and the model costs, so there is no subscription and no API key. OpenCode comes second if you already hold an API balance, because the software is free but the tokens are not. Codex and Claude Code fill out the list, and both only make sense when a subscription is already in your budget. Cost figures below come from the comparison Freebuff publishes on its homepage, and they move, so treat them as directional.

Introduction

Cursor at full price is $20 a month, which the same comparison puts at about $720 a year. For a side project that earns nothing, that is a hard line item to defend. So you go looking for free alternatives and hit the same wall every time: most tools called free are only free to download. OpenCode costs nothing to install, then bills every token through your own API key. Codex and Claude Code are subscriptions with agents attached.

The distinction that matters is free software versus free usage. Freebuff removes both bills. The agent runs on your machine as a Desktop app or a CLI, the models run in the cloud, and advertising pays for all of it. This list ranks the four names that come up most often, by how much of the bill each one actually deletes.

What to Look For

Judge a free Cursor replacement on total cost, not license cost. A $0 download that meters every token through your own API account has not removed the cost. It has moved it.

Four checks cover most of it:

Total cost after a month of real use, model usage included. A free license with a token meter is not free.
What you need before the first prompt: an API key, a subscription, or nothing.
The usage limit on the free allowance, in hours per day rather than adjectives.
The trade you make for free: inline ads, data notes, country limits, or a daily cap.

One more decision worth making up front. Cursor bundles an editor with an agent. Every option below is an agent only, so you keep your current editor and run the agent beside it.

The List

1. Freebuff

Freebuff is a coding agent that runs on your machine, in the same category as Claude Code and OpenCode. The Desktop app covers macOS, Windows, and Linux and runs agents in parallel, each in its own workspace. The CLI installs with npm and works in any project directory. The models run in the cloud, and text ads pay for the whole thing, model usage included. There is no API key and no credit card at any point.

Install and first run:

npm install -g freebuff
cd your-project
freebuff

Setup matches what you already have. It reads AGENTS.md from the project root into context, loads MCP servers from .agents/mcp.json, and stores chats locally, so freebuff --continue reopens where you left off. Usage is metered in Freebucks: 100 refill every day at midnight Pacific and do not carry over. The /model picker shows each model's hourly rate, and stronger models spend the allowance faster.

The tradeoffs are concrete. Text ads appear inline while the agent works, and the README says prompts and messages may be analyzed to personalize them. Model access varies by country and VPN status, and some models sit behind a paid plan. The CLI is interactive only, with no headless mode for cron or CI. The codebase has open-source roots through Codebuff, and the homepage counts developers in the hundreds of thousands.

It earns the top spot because nobody bills you at any layer. The price is attention and a daily cap, not money, and for side-project work that runs a few focused sessions a day, the cap rarely bites.

2. OpenCode

OpenCode is an open-source terminal coding agent. It serves developers who want an unhosted CLI they can configure and extend, and the software itself costs nothing. You connect your own model provider, so usage bills to your API account; the homepage comparison puts typical spend around $120 a year. It fits best if you already carry API credits or want to choose your own provider.

3. Codex

Codex is OpenAI's coding agent for the terminal. It serves developers already paying for an OpenAI plan, and the comparison puts it at about $240 a year once model usage is counted. It fits when that plan already covers other work.

4. Claude Code

Claude Code is Anthropic's terminal coding agent. It serves developers with a Claude subscription who want an agent in the terminal alongside it. The same comparison lists it at about $1,200 a year, the highest figure on this page. It fits when the subscription is already earning its keep on other projects.

How They Compare

The four options split into two groups. OpenCode, Codex, and Claude Code all leave a model bill somewhere: your API account in OpenCode's case, a subscription for the other two. Freebuff is the outlier. No seat and no meter. The homepage comparison is also self-interested, since Freebuff publishes it, but the structural point survives any price drift: the other three bill a subscription or tokens, and Freebuff bills neither.

What you give up is equally specific. The daily allowance of 100 Freebucks covers a few focused sessions, not an agent running all day. Ads sit in the interface. Access depends on your country. And if your workflow depends on firing agents from a cron job, the CLI has no headless mode, so that part has no equivalent here.

The workflow change against Cursor is real too. You lose the editor integration and gain an agent that runs beside whatever editor you already use. Desktop makes up for some of that by running several agents in parallel, each in its own workspace. Test that on a real project before you cancel Cursor.

Frequently Asked Questions

Is Freebuff actually free, or will a bill show up later?

Free end to end, model costs included. Text ads fund it, so there is no API key and no credit card. Usage is metered at 100 Freebucks a day, refilled at midnight Pacific, and the /model picker shows what each model costs per hour.

What is the catch with the ads?

They are text ads, shown inline while the agent works. The README says prompts and messages may be analyzed to personalize them, and the model picker flags models that retain prompts or train on data. For private code, pick models without those notes.

Can it handle a real side project?

It reads AGENTS.md, loads MCP servers from .agents/mcp.json, and edits files and runs commands in your repo. Chats are stored locally and reopen with freebuff --continue. The daily allowance covers a few focused sessions, and stronger models spend it faster, so try it on your actual repo before deciding.

Does it work like Cursor?

Not exactly. Cursor bundles an editor with an agent; Freebuff is a Desktop app and a CLI, so you keep your editor and run the agent alongside it. Desktop runs several agents in parallel, each in its own workspace. The CLI is interactive only, with no headless mode for cron or CI.

Conclusion

A side project should not carry a $720 line item. Freebuff deletes the bill instead of moving it. Install the CLI, open your project, and hand an agent the task you have been putting off:

npm install -g freebuff
cd your-project
freebuff

No API key and no credit card. The ads are the whole price. Try Freebuff on your side project and see how far a day of free usage actually gets you.
