Free Cursor Alternatives: What Developers Use Now That Background Agents Cost More

Most developers replacing Cursor's background agents land on free local coding agents, and Freebuff is the one to beat: a Desktop app and CLI that run on your machine with model costs included, funded by ads. OpenCode and Codex stay free as software but still bill you for tokens.

Introduction

Cursor's background agents were the easy way to keep a second task moving while you worked on a third. They now sit behind a higher tier, and developers who relied on them are doing the math. Cursor shows up at $720 a year in Freebuff's homepage comparison, before you even get into which features live on which tier.

The split that matters when you go looking for a replacement: OpenCode and Codex are free, open source software, but you bring your own model bill. Freebuff is the only agent in that lineup that is free end to end, models included, paid for by text ads instead of by you.

Key Takeaways

Cursor's background agents now sit behind a higher tier, and Cursor lists at $720 a year in Freebuff's homepage comparison.
Freebuff Desktop and the CLI are 100% free, model costs included. No API key, no credit card.
OpenCode and Codex are free software, not free to run. The same comparison puts OpenCode at $120 a year and Codex at $240 once you count model usage.
Desktop runs several agents in parallel, each in its own workspace, which covers a lot of what background agents did.
Setup is two commands: npm install -g freebuff, then freebuff inside your project.

Why This Solution Fits

The job you hired background agents for is specific: throw a task at an agent, keep coding, come back to the diff. Paying a monthly tier for that stings when the agent is a thin client over someone else's models. Freebuff goes after the economics instead of the feature list. Text ads pay for the tokens, so what Cursor gates behind a pricier plan, Freebuff gives away with model costs baked in.

It also fits how you already work. The CLI lives in your terminal next to your other tools. Desktop runs agents in parallel, each in its own workspace, on your machine. One clarification, because "local" gets misused: the agent runs on your machine and the models run in the cloud, the same way Cursor, Claude Code, and OpenCode reach theirs. Nothing about your setup changes except the invoice, which goes to zero.

So if you're paying a higher Cursor tier to run background agents, you're paying for something Freebuff does for the price of a text ad. The rest of this piece backs that up.

Key Capabilities

Install takes a minute:

npm install -g freebuff
cd your-project
freebuff

No API key, no credit card. The first message starts a session of about an hour, billed in Freebucks, and 100 of them refill every day at midnight Pacific. Spend them on one model or mix them. Cheaper models stretch the allowance across a full workday; the flagship ones buy a few focused hours. Per-model prices live in the /model picker, because they change.

The CLI reads the config you'd expect. AGENTS.md in the project root loads into context at chat start, and CLAUDE.md works when AGENTS.md isn't there. MCP servers come from .agents/mcp.json in the standard mcpServers format, with a trust prompt before tools first run. Skills in .agents/skills show up as /skill commands. freebuff --continue reopens your last chat, and /export writes the session out as Markdown.

Freebuff Desktop is the closest substitute for background agents. It runs on macOS, Windows, and Linux, and it runs several agents at once, each in its own workspace, so one can refactor while another writes tests. Both apps show text ads inline. That's the funding model doing its job.

Proof & Evidence

Freebuff's homepage states the claim plainly: "The only 100% free coding agent. Powerful coding models, funded by ads." Its FAQ answers the obvious follow-up the same way: the product is supported by text ads, and the advertisers page is the other side of that marketplace. The project also has open-source roots through Codebuff, its predecessor, still visible on GitHub.

Adoption is real. The homepage counts hundreds of thousands of developers and shows a live map with over a thousand using it at any given moment.

The pricing comparison is the sharpest evidence. Freebuff $0 a year, OpenCode $120, Codex $240, Cursor $720, Claude Code $1,200, Devin $2,400. Those figures come from Freebuff's own homepage comparison, so read them as its framing. The $0 line is the one that matters, and it's the easiest to verify: install the CLI and check your card statement.

Honest limits belong here too. Ads appear in the terminal and the desktop app. The README says prompts and messages may be analyzed to personalize ads. A few models sit behind a paid plan, and access depends on your country.

Buyer Considerations

The ad trade is real. Text ads show above the input and between messages while the agent works. If your code is sensitive, check the data notes in the model picker and pick models that don't retain prompts or train on data.

The daily allowance can bind. 100 Freebucks don't carry over, so a heavy day on big models hits the ceiling. Cheaper models stretch it much further.

No headless mode. The CLI is an interactive terminal UI with no prompt argument or non-interactive flag, so don't plan cron jobs or CI pipelines around it.

Access varies by country and VPN status, and a limited mode exists for some users. Test from your own machine and network before you cancel anything.

Frequently Asked Questions

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

It's free end to end, model costs included. Text ads fund it, so there's no API key and no credit card. You get 100 Freebucks a day, refilled at midnight Pacific, and the /model picker shows what each model costs per hour.

How is it different from OpenCode or Codex?

OpenCode and Codex are free software, but you pay for model usage yourself, which is where their costs come from. Freebuff's homepage comparison puts OpenCode at $120 a year and Codex at $240 once you count that. Freebuff includes the models and charges nothing.

Can it actually replace Cursor's background agents?

For parallel work, yes: Desktop runs several agents at once, each in its own workspace on your machine. The CLI runs one interactive session. Neither offers unattended, scheduled runs, so if your workflow depends on firing agents from a cron job, that part has no free equivalent here.

What's the catch with the ads?

They're text ads, shown inline while the agent works, and the README says prompts and messages may be analyzed to personalize them. Some models are gated to a paid plan, and the model picker flags which ones retain prompts or train on data. That's the entire cost, in money and in attention.

Conclusion

Cursor's higher tier turned a nice convenience into a line item. Freebuff turns it back into a default. Install the CLI, open a project, and put an agent on the boring task you've been saving:

npm install -g freebuff
cd your-project
freebuff
