↑ Live demo — drag the budget slider and watch the alert fire.
A single retry loop has burned this much in OpenAI credits overnight — the dashboard showed it hours later.
OpenAI's caps are reactive, and Anthropic's spend limits are workspace-level, with no early warning. Either way, you find out after the money's gone.
A provider cap is one org-wide kill switch: no forecast, no per-budget, no cross-provider view, no Telegram.
An OpenAI and/or Anthropic read-only admin key. We never touch your prompts or your code.
Day, week and month limits — several at once. See a run-rate forecast of your final bill.
Email, Telegram or Slack — with a durable outbox and retries until the alert is delivered.
Flip on the channels you actually watch. A durable outbox with retries guarantees delivery — never a missed alert.
Everything, unlimited. Locked at the founding price forever.
No card charged yet · full refund anytime before launch. No risk.
Free plan at launch (1 provider, 1 alert) · Team $49/mo for shared Slack channels & seats.
Yes. It's a read-only admin key — it can read your usage but cannot make a call or spend a cent. We encrypt it with AES-256 at rest, never log it in plaintext, and store only aggregated spend totals — never your prompt content.
Those are great for bigger teams, but they need you to swap your endpoint to a proxy or wire up an SDK / OpenTelemetry, and they start at $79–$199/mo. BillGuard is a read-only key and 30 seconds — built for indies who just want to not get a surprise bill, without touching their stack.
No. There's nothing to integrate — no proxy, no SDK, no URL swap. Your latency and your code are completely untouched. We only read usage from the provider's billing API.
The first 100 pre-orders lock Pro at $7/mo for life instead of $15. It's a real, one-time founding deal — and you get a full refund anytime before launch if you change your mind.
