If you've used an AI coding agent for any real work this year, you know how the bill goes. It starts at twenty bucks a month. Then you hit a usage cap halfway through a refactor. Then there's a "pro" tier, then credits, then overage pricing for the good models. For a big company that's a rounding error. For a one-person shop or a small IT business here on the Island, it adds up fast, and it's hard to justify when you're not sure how much you'll use it next month.

Freebuff is an AI coding agent. You point it at a project, tell it what you want, and it reads your code, makes changes, and runs things for you. Same basic idea as the paid agents most developers have tried by now.

The difference is the business model. There's no subscription, no credit card at signup, and no credits to run out of. Ads pay for it.…
