Freebuff

A coding agent you can actually install

Paid coding agents usually ask for a subscription, a credit balance or an API key before you can try them. Freebuff takes the opposite route: the provider describes a free agent for the terminal, desktop and web, funded by advertising rather than by you.

The practical effect is that you can evaluate the workflow without a purchase decision. The trade-off is the usual one for free services — your usage, your attention, or both, are part of the business model — so read the provider’s own terms and privacy documentation rather than our summary.

Your referral link

The link we were given is the provider’s start URL with a referring account attached. Opening it records the referral for the provider; nothing is applied on your behalf beyond that, and any benefit attached to the referral is decided by Freebuff.

You do not need to type or copy a code. If the provider changes how referrals work, the link will follow whatever the provider does next, which is why we describe it as an invitation rather than a discount.

What the workflow looks like

1. Point it at a project. Start in the directory you want changed, on a clean branch, with your work committed or stashed.
2. Describe the outcome. A clear goal with constraints beats a vague request. Mention the framework, the files you care about and what “done” means.
3. Watch it work. The agent reads files, edits code and may run commands. Terminal access is the part to supervise most closely.
4. Read the diff. Review changes before accepting them. Small, reviewable steps are safer than one enormous rewrite.
5. Run your checks. Tests, linters and a manual pass on the affected screens. Passing tests are evidence, not proof.

Where it fits, and where it does not

It is a good fit for mechanical work: scaffolding a feature, writing tests around existing behaviour, refactoring repetitive code, wiring a small integration and explaining an unfamiliar file. Running agents in parallel across separate workspaces helps when the tasks are genuinely independent.

It is a poor fit for work needing context it cannot see — a private roadmap, a customer conversation, a security decision — and for anything you cannot review. Treat its output as a competent colleague’s first draft, not as a finished change.

Sensible guardrails

• Work on a branch, never directly on your release branch.
• Keep secrets out of prompts, and check what the tool reads before you start.
• Prefer a scratch copy for anything regulated or confidential.
• Commit often so a bad edit is one revert away.
• Decide who reviews generated code, and make sure it is a person.
