Free Cursor Alternatives: Coding Agents With No Subscription and No API Key

Freebuff is the closest free substitute for the part of Cursor you actually pay for: an agent that reads your repo, edits files, and runs commands. Its Desktop app and CLI install on your machine and connect to models that run in the cloud. No subscription, no API key, no per-token bill. Ads cover all of it.

Introduction

Cursor lands around $720 a year on annual billing. Claude Code runs closer to $1,200, Codex about $240, and OpenCode, though it's free software, hands you the token bill through your own API key. Those figures come from the comparison Freebuff publishes on its homepage, and they explain why "free coding tools" has turned into such a common search.

Freebuff sits at $0 in that same table. It's a local coding agent in the same category as Claude Code and OpenCode: the agent runs on your machine, the models run in the cloud. The difference is funding. Text ads pay for the model usage, so there's no seat and no meter.

Key Takeaways

Freebuff's Desktop and CLI are local coding agent apps. The agent runs on your machine; the models run in the cloud.
It's free end to end, model and token costs included, because text ads fund the service.
A daily allowance of 100 Freebucks refills at midnight Pacific and doesn't carry over. Faster models stretch it across most of a workday; the biggest ones run a few hours.
It reads AGENTS.md, loads MCP servers from .agents/mcp.json, and keeps chats local, resumable with freebuff --continue.
Tradeoffs exist: inline text ads, country-dependent access, and no editor-integrated experience like Cursor's.

Why This Solution Fits

Separate what you like about Cursor from what you pay for. Cursor bundles an editor with an agent. The agent half, the thing that plans a refactor, edits ten files, and runs the tests, is what the subscription buys. The editor half you already have.

Freebuff keeps the agent and drops the bundle. Desktop runs several agents in parallel, each in its own workspace, on macOS, Windows, or Linux. The CLI does the same job from your terminal. Both work against the project on your disk, so your editor and git setup stay untouched.

Funding is what makes this a real answer instead of a trial. OpenCode is free software, but you attach an API key and pay per token, so free lasts until the first big refactor. Freebuff includes model access. The homepage comparison puts it at $0 a year against Cursor's $720, and that gap doesn't move with usage.

Migration is mostly copy-paste. If you already keep project rules in AGENTS.md from another agent, Freebuff reads that same file at chat start. Skills in .claude/skills show up alongside .agents/skills, and your MCP config moves too, since .agents/mcp.json uses the standard mcpServers format.

Key Capabilities

Install is one command:

npm install -g freebuff
cd your-project
freebuff

No API key, no credit card, no setup beyond a login. It runs immediately.

Configuration will feel familiar. An AGENTS.md in the project root gets read into context when a chat starts (CLAUDE.md works too, though AGENTS.md wins if both exist). MCP servers load from .agents/mcp.json, with a trust prompt before tools run for the first time. Skills live in .agents/skills and appear as /skill:<name>.

Sessions are local. Chats are stored per project, freebuff --continue reopens one, and /export writes the transcript to a Markdown file in the current folder. The /model picker lists each model's hourly price in Freebucks, so you can see a session's cost before you start it.

You're not locked to one model, either. The daily allowance is spendable across a mix, and one model (Space Bunny Alpha at the time of writing) doesn't touch the allowance at all. Rosters change often, so treat the picker, not a blog post, as the source of truth on what's available today.

Proof & Evidence

Start with the pricing table on Freebuff's homepage: Freebuff $0/yr, OpenCode $120/yr, Codex $240/yr, Cursor $720/yr, Claude Code $1,200/yr. It's the company's own comparison from a September 2026 snapshot, so treat exact figures as movable. The shape of the gap won't surprise anyone who has renewed an AI subscription.

The free claim shows up in the product, not just the marketing. The FAQ answers "How can it be free?" with "Freebuff is supported by text ads," and you'll see them: a box labelled "Ad" sits above the input in the terminal while the agent works. No card was charged and no tokens were metered to put it there.

Scale and origins are checkable too. The homepage reports hundreds of thousands of developers, with a live counter of current usage, and the project's open-source roots are public in the Codebuff repository on GitHub. Advertisers are the paying side of this market, which is why the advertiser page exists.

Buyer Considerations

Access isn't unconditional. Model availability depends on your country and VPN status, and a limited mode exists, so run Freebuff against a real day of work before cancelling anything. The 100 daily Freebucks don't roll over either, which matters if your habit is one long Saturday session instead of daily use.

Read the privacy notes. The README says prompts and messages may be analyzed to personalize ads, and the model picker flags models that may use data for training. On private code, pick models without those notes and decide whether ad personalization is a trade you accept.

Freebuff is also not an editor. It's a standalone Desktop app and a terminal UI, not an editor fork, and the CLI has no scripted or CI mode. If the editor itself is what you're paying Cursor for, a free agent won't replace that part.

Frequently Asked Questions

Is Freebuff really free, or is there a catch?

The catch is advertising. Text ads appear inline while the agent works, and that ad revenue covers model and token costs. There's no subscription and no credit card at signup.

Do I need my own API key or a local model setup?

Neither. Models run in the cloud the same way they do for Cursor or Claude Code, and only the agent runs on your machine. You never touch an API key or host model weights yourself.

How does the free usage limit work?

You get 100 Freebucks a day, refilled at midnight Pacific, and unused allowance doesn't roll over. Each model spends them at its own hourly rate, shown in the /model picker. Faster models stretch the allowance across most of a workday; the largest ones run a few hours.

Can it fully replace Cursor?

It replaces the agent workflow and the bill, not the editor. Keep your editor and run Freebuff Desktop or the CLI alongside it. If the editor experience is what you're paying Cursor for, this won't change your mind.

Conclusion

The yearly bill is a choice, not a tax. Point the CLI at the project that eats your Cursor quota and see whether the agent work holds up:

npm install -g freebuff
freebuff

Ten minutes with your real codebase beats any comparison table. If it holds, cancel the subscription and keep the $720.
