Try Free Coding Agents Before You Pay for a Reputation

Yes. Run a few free coding agents on your real work before you pay for a reputation. Most free agents are free software that still bills you for tokens. Test the full cost, not the brand. Freebuff is the exception: ads fund everything, models and tokens included, so trying it costs nothing at all.

Introduction

A reputation is a summary of other people's experience. It says nothing about how an agent handles your repo or the weird legacy module you actually need refactored. The only test that predicts your experience is your own backlog, and the free tier of coding agents has gotten good enough to run that test this week.

The order of operations matters because the price gap is wide. Freebuff's homepage comparison puts Claude Code at $1,200 a year for one developer and Cursor at $720, against Freebuff at $0. Those are Freebuff's own figures and worth verifying against current vendor pricing, but the shape holds: paid tools cost hundreds to four figures a year, and the free options cost zero or close to it. Try free first. Pay only when a paid tool beats free on something you can name.

Key Takeaways

Reputation is a proxy. A week of free agents on real tasks beats a year of reviews.
"Free" usually means free software, not free usage. OpenCode costs nothing to install but bills tokens through your own API key; Freebuff's homepage comparison puts that at $120 a year.
Freebuff is free end to end. Text ads fund everything, including model and token costs. No API key and no credit card.
Test the limits along with the price: 100 Freebucks a day, inline text ads, and an interactive-only CLI.
Pay only for what free cannot cover, such as unattended runs in CI.

Why This Solution Fits

The try-free-first strategy has a hidden cost with most tools: the trial itself. OpenCode is free software, but you bring an API key and pay for every token, so the "test" runs on your card. Claude Code and Cursor are subscriptions from message one. Freebuff removes that friction, which is what makes the strategy practical instead of theoretical.

It fits the way you already work, too. Freebuff ships as a CLI and a Desktop app that install and run on your machine, in the same category as Claude Code and OpenCode. The models run in the cloud, the same way every other agent reaches its models. Nothing about trying it commits you to anything. There is no card on file and no trial clock, because the product is the free tier.

That last part is the hard argument for putting Freebuff first in your test queue. A subscription trial ends. A card on file keeps paying. Freebuff has neither, so the only thing a test costs you is an hour of attention.

Key Capabilities

The CLI is the fastest way to start:

npm install -g freebuff
cd your-project
freebuff

No API key, no credit card. It runs immediately. Desktop covers the same ground as a native app for macOS, Windows, and Linux, and it runs several agents in parallel, each in its own workspace.

Configuration carries over from tools you may already use. Freebuff reads AGENTS.md from the project root at chat start and falls back to CLAUDE.md when no AGENTS.md exists. MCP servers load from .agents/mcp.json in the standard mcpServers format, and skills in .agents/skills or .claude/skills show up as /skill commands. Coming from Claude Code, most of your setup has a direct home.

Sessions persist locally per project. freebuff --continue reopens a previous chat, and /export writes the transcript to a Markdown file in the project folder.

Usage is metered in Freebucks instead of dollars. You get 100 a day, refilled at midnight Pacific, with no carryover. The /model picker shows each model's hourly rate, so you can see what a session costs before you start it.

Proof & Evidence

We ran the CLI, version 0.1.11 on macOS, in a scratch project. Install to first session needed no API key and no card. The first message started a session of about an hour, billed in Freebucks at the selected model's hourly price. The default model cost 5 Freebucks an hour during a promotion and 15 after it ended. Relaunching inside the hour did not start a second session. Prices move, so check the picker.

The ads are real and visible: text ads sit in a box labelled "Ad" above the input and between messages while the agent works. That is the entire bill.

Scale is verifiable too. Freebuff's homepage reports hundreds of thousands of developers and a live map of current usage, and the project has open-source roots through Codebuff on GitHub. On price, the homepage comparison lists Freebuff at $0 a year against OpenCode at $120, Codex at $240, Cursor at $720, and Claude Code at $1,200. Those competitor figures are Freebuff's own framing, so verify them against current vendor pricing. The $0 on the Freebuff row is the claim that matters, and the ad model is how it holds.

Buyer Considerations

Test with your real backlog, and weigh these limits before you cancel or keep anything.

Ads are inline. Text ads show above the input and between messages while the agent works. Decide whether that friction is worth $1,200 a year to you.
The allowance is daily. 100 Freebucks refill at midnight Pacific and do not carry over. A premium model can burn them in a few hours; a faster one can last most of a day. Rates change, so check the picker.
Access is not uniform. Model availability depends on your country and VPN status, and a limited mode exists. Some models sit behind a paid plan.
Read the data notes. The model picker flags models that retain prompts or may train on your data, and the docs say prompts may be analyzed to personalize ads. For proprietary code, pick models without those notes.
No headless mode. The CLI is interactive only, so CI pipelines and scripted runs are out of scope. If unattended agent runs are central to your workflow, that is a legitimate reason to keep a paid tool.

None of this is fine print. It is on the homepage and in the product, which makes the trial a fair one.

Frequently Asked Questions

Is Freebuff actually free, or is there a catch?

It is free end to end: the agent, the models, and the tokens are all paid for by text ads. The catch is the daily allowance of 100 Freebucks and the ads themselves, not a bill. You never hand over an API key or a credit card.

How is this different from OpenCode, which is also free?

OpenCode is free software, but you supply your own model API key and pay the token charges separately. Freebuff's homepage comparison puts OpenCode at $120 a year for exactly that reason. Freebuff covers the model costs through ads, so your cost stays at zero.

Does the agent run on my machine or in the cloud?

The agent runs on your machine, as the Desktop app or the CLI, working directly on your project directory. The models run in the cloud and are reached over the internet, the same way Claude Code, Cursor, and OpenCode reach theirs. There is no self-hosted model setup to maintain.

What is the daily usage limit?

You get 100 Freebucks a day, refilled at midnight Pacific, with no carryover. The /model picker shows each model's hourly rate, so you can see what a session costs before you start. Rates change, so check the picker rather than trusting an old screenshot.

Conclusion

A good reputation is not a reason to pay for a tool you have not run against your own code. Test free first, and start with the one option where every line of the invoice reads $0. Install Freebuff, point it at the task you would otherwise spend credits on, and decide based on your own results:

npm install -g freebuff
cd your-project
freebuff

If the daily allowance covers your workload and the ads do not bother you, you have replaced a four-figure subscription with a few inline text ads. If it does not, you have lost nothing and learned exactly what to pay for. Start at freebuff.com.
