Why Nib

Built for the work between prompts.

Most tools stop at a chat box. Nib runs commands, reads the result, and decides what to do next. The difference shows up on real repositories, not demos.

It reads before it writes

Nib maps the repository first: entry points, tests, build scripts, the files that actually matter. Edits land where they belong, not in a plausible-looking neighbour.

It closes the loop

Run the test, read the failure, change the code, run it again. You get a result and a diff, not a suggestion you have to paste somewhere.

One key, every tool

Your plan includes an API key that works with Cline, Continue, Zed, and any OpenAI-compatible SDK. Same credits, same models, no second bill.

Plans

Plus $10 · Pro $30 · Max $90.

Every paid plan includes every model. Higher tiers add a larger balance and more concurrent sessions — that is the whole difference.

Questions

Before you install.

What exactly is Nib?

A desktop AI coding agent. It lives on your machine, reads your repository, edits files, runs your tests, and keeps going until the work is done. A subscription covers the agent and a monthly allowance of model usage.

Which platforms are supported?

Windows x64 is available now. macOS (Apple silicon and Intel) and Linux x64 builds are in progress and will be published on the download page — nothing to reinstall, your account just keeps working.

What am I paying for?

A monthly subscription that includes a fixed amount of model usage, measured in credits, plus the API key for other tools. Ten credits equal one dollar of usage at our published model rates.

Do you publish per-model prices?

No. We charge each model at one rate, and ten credits equal one dollar of that usage. Every request reports what it cost, and the app shows the estimate before it runs.

What happens when I run out of credits?

Requests draw from your top-up balance if you have one, otherwise they pause until your credits reset or you upgrade. A daily cap of 25% and a weekly cap of 60% of your monthly credits keep one runaway session from eating the month.

Can I use the same subscription in other tools?

Yes. Create an API key in the console and use it with any OpenAI-compatible client or SDK. The same credits apply. See the API docs for base URLs and protocol support.

Can my team share one account?

Plans are per account, and the concurrency limit is what decides how many people can use it at the same time: 3 sessions on Plus, 10 on Pro, 30 on Max. Upgrade when you need more people working at once.

Is Nib based on an open-source project?

Yes. Nib is a distribution of OpenCode, which is MIT licensed. We add login, credits, model routing, and the desktop client.

What if I want a refund?

First subscription: 14 days, minus usage already consumed. Renewals are non-refundable once the period starts. Full terms are in the refund policy.

Install it. Then forget it is there.

Nib stays on your desktop, remembers your repository, and shows you the bill.
