FAQ

Short answers, no marketing.

What is Haider?

A first-party coding-agent harness: one Rust binary that is the TUI, the headless runtime, and the per-device daemon, where every piece of interior state is a typed, queryable contract.

Do I need Go to use Haider?

No. The harness is free with your own provider keys. Go is hosted models for people who do not want to manage keys.

Can I use my Claude or ChatGPT subscription?

Yes — the harness owns OAuth flows for Claude subscriptions and OpenAI codex. They run locally; subscription traffic never routes through our servers.

What does Go cost?

$40/month for Go — the starter plan with a limited weekly allowance — or $200/month for Go Max with 20× the usage at 5× the price, metered over rolling 7-day windows. usage-credits top-ups are plain dollars.

Is my code private?

The harness is local-first: code, transcripts, and credentials stay on your machine. Go requests pass through the gateway to reach hosted models, but prompt bodies are never logged.

Can my team share billing?

Yes — invite members from the dashboard. A member's usage bills the inviter's account.
