FAQ
What teams ask before connecting.
How syncing, permissions, forecasts and billing work.
How fast does Costbrake catch a spike?
As fast as the provider reports it. Pro and Team check every 5 minutes, and up to every minute while a spike is running. Cloudflare, Vercel, GitHub, OpenAI, Anthropic and most other API providers report usage within minutes, so a spike alert usually lands within minutes too. Google Cloud's billing export runs hours behind and AWS Cost Explorer up to a day, so spikes there show up within hours, still weeks before the invoice. Free checks every hour.
Can my AI agent set Costbrake up for me?
Yes. Tell Claude Code, Codex, Cursor or a chat assistant with tools: "Set up Costbrake for me: https://costbrake.com/agent". It sends you one link to sign in with Google and allow it, then connects the providers it has keys for, sets a budget, points alerts at you and reports back. It can't brake anything, change billing or invite people, and its access ends after an hour.
Does Costbrake need write access to my accounts?
No. Costbrake reads usage and billing data and changes nothing unless you use the killswitch. Wherever a provider offers read-only access, that's all it needs to watch spend, like an AWS IAM user that can only read Cost Explorer or read-only tokens on Cloudflare and GitHub. Anthropic, Neon and Vercel have no read-only keys, so Costbrake only calls their usage and billing endpoints with them. You can revoke a key at any time.
How is this different from AWS Budgets or Cost Anomaly Detection?
Those only see AWS. Costbrake puts AWS next to Cloudflare, GitHub, OpenAI and the rest, with one budget, one forecast and one alert inbox for all of them. You can keep the AWS tools running alongside it.
How does the forecast work?
It adds month-to-date spend to the pace of the last 72 hours, carried through to the end of the month. It updates with every sync, and on Pro and Team you get an alert once a budget is on pace to be crossed.
What counts as an account?
One connection to one provider account: an AWS payer account, a Google Cloud billing account, a Cloudflare account, a GitHub organization or a Vercel team. Free covers 2, Pro 10 and Team 50.
Can I set budgets per team or project?
Yes, on Pro and Team. Put a budget on one provider, one service or one project, like a Vercel project, an OpenAI project or a Cloudflare Worker, and get alerts for it alone. AWS and Google Cloud split per service, not per tag or label.
Is there a free plan?
Yes. Free covers 2 accounts with hourly syncs, 30 days of history and email alerts, with no time limit and no card. Pro is $12 a month and Team $39 a month, with 2 months free when billed yearly.
