Cursor. Copilot. Claude. OpenAI API. ChatGPT. All of it — one dashboard, $49/month, flat. Built for the person who actually pays the bill.
Every existing AI observability tool tracks API calls — that's it. Your Cursor, Copilot, and Claude subscriptions are completely invisible.
Founders, CFOs, CTOs need cost visibility — but every tool requires code changes and speaks in "tokens" and "spans."
Your observability bill spikes the moment usage does. Every competitor charges more when you need them most.
API providers connect with a single key. Subscriptions link via OAuth so we can see seats, invoices, and renewal dates — not just usage.
Tag by team, project, person, or environment. We attribute every dollar automatically without traces or instrumentation.
Per-provider or rollup budgets. Alerts at 80% and 100% land in Slack or email — before the surprise invoice does.
Try it on one team's stack.
Unlimited providers. 12 months of history. Board-ready exports.
Everything in Pro, plus per-seat attribution and SSO.
No. We read billing endpoints and invoice metadata, not request content. Your prompts never touch our servers.
Existing tools are observability platforms — they trace API calls. Stax is a finance tool — it tracks every dollar, including the $840/yr/dev you're spending on subscriptions that never appear in any observability dashboard.
Because cost-control software shouldn't be a variable cost. If your bill triples next month, ours doesn't.
Yes — and you can connect Brex, Ramp, or Stripe Issuing so the Stax charge itself is auto-tagged.
Email us. We add the top-requested provider every two weeks. In the meantime, drop your invoice and we'll track it as a flat-cost line item.
Yes — 3 providers, 30 days of history, forever. No card. Most folks upgrade when they hit provider #4 or want history past last month.
