AWS has no spending limit.
BillStop gives you one.
Forgotten servers. Runaway GPU jobs. Leaked keys mining crypto at 2am. BillStop catches them in seconds, tells you exactly what they'd cost, and stops them before your limit blows. Set a limit and BillStop actually enforces it — the runaway and the slow leak — no cloud expertise required.

The full protection loop
Caught in seconds, priced instantly, stopped before your limit — and if money burned anyway, we help get it back.
Burn Detected
Something expensive starts — a launch (caught in seconds via AWS events) or silent AI token burn on Bedrock (caught in minutes via live usage counters). No waiting on billing data.
Priced Instantly
BillStop estimates what it burns — ≈$/hr and ≈$/mo — and checks it against YOUR limit: “at this rate, your $100 limit is gone in ~33 hours.”
You Know Immediately
Email, dashboard, and Slack — the alert names what launched, where, what it costs, and when your limit dies. Actionable, not vague.
Circuit Breaker Trips
If a launch is forecast to blow your limit, BillStop stops it — reversibly, never deleting anything. Turn on the hard cap and it also stops whatever's already running the moment your actual spend hits the limit. Your call: alert only, dry run, or circuit breaker.
Waste & Stealth Fees Found
Between emergencies, BillStop hunts the quiet leaks: idle servers, unattached disks, zombie IPs — plus hidden fees like the RDS Extended Support surcharge. One click sweeps every region for an all-clear.
Worst Case? Refund Rescue
If a surprise bill lands anyway, one click writes the AWS support ticket that gets honest first-time charges waived — with BillStop's incident timeline attached as evidence.

More than a kill switch
Everything you need to never think about AWS bills again.
AI Circuit Breaker
The moment something expensive launches — by you, a script, or leaked keys — BillStop prices it and, if it would blow your limit, stops it automatically. Reversible, never deletes.
A real spending limit
AWS has no hard cap. Turn on the hard cap and BillStop stops everything already running the moment your actual month-to-date spend reaches your limit.
Budget Rules
One overall monthly cap, or a separate budget for each AWS service. BillStop watches every dollar and warns you at 80% and 100% by email and Slack.
All-Clear Scan
“Is anything, anywhere still costing me money?” One button sweeps every AWS region — and flags stealth fees like the RDS Extended Support surcharge (it doubled in March) and billed public IPv4s.
AI Burn Watch
AI agents never “launch” anything — they burn tokens silently until the invoice lands. BillStop reads Bedrock's live usage counters and warns in minutes when the burn endangers your limit.
Waste Finder
Hunts what you forgot: idle servers, unattached disks, zombie IPs — each priced per month. Stop them in one click; stopping is always reversible.
No keys. Ever.
Connect through a read-only role created in your own AWS console — about 2 minutes, every permission auditable. Revoke anytime by deleting one stack.
Reports & Slack
Formatted Excel and PDF cost reports on demand, alerts in your Slack channel, and a monthly recap in your inbox. Your accountant will like you.
Refund Rescue
If a surprise bill lands anyway, one click writes the AWS support ticket that gets honest first-time charges waived — with your incident timeline attached as evidence.
It happens more than you think.
Real stories from developers who got burned.
"A hobby static site went viral — 60 TB of bandwidth before anyone noticed."
"An AI workload billed past a cap the customer believed was on. The lag did the damage."
"A coding agent left running while its owner slept. Token billing plus a loop did the rest."

Frequently asked questions
How does the free trial work?
Every account starts with a 7-day free trial — full access to everything (Circuit Breaker, All-Clear Scan, Waste Finder, reports). You add a card to start, aren’t charged for 7 days, and can cancel anytime before then. After the trial it’s $19/mo.
Is my AWS data safe?
Yes. BillStop connects through a read-only cross-account IAM role you create in your own console — there are no access keys to paste or store. We can see your costs but can never create, modify, or delete a resource, and you revoke access anytime by deleting one stack.
How is this different from AWS Budgets?
AWS Budgets reacts to billing data that lags 8–24 hours, and only catches what you budgeted for. BillStop reacts to the launch event itself — in seconds — prices it, and can stop it before your limit blows. You can also do this with AWS Budgets Actions if you’re happy writing the IAM policies yourself; BillStop is the 2-minute, no-setup version.
What if I go over my limit?
On the Free plan you get an instant alert. On paid, the Circuit Breaker automatically stops the runaway before it gets worse — reversibly, never deleting anything.
Which cloud providers do you support?
AWS today. GCP and Azure coming soon.
Can I cancel anytime?
Yes. No contracts, no cancellation fees. Cancel in one click from your dashboard.
