What happens after you pay

Pay once via Polar

Card or wallet. Polar is the merchant of record and handles tax.

Your key lands by email

A license key arrives within seconds — and the checkout page shows a one-paste command with it already embedded.

One-paste install

The key is dropped into the command for you — nothing to type by hand.

curl -fsSL https://usetare.dev/install.sh | TARE_LICENSE=<key> sh

Run tare today

Start coding — your savings ledger fills up from your first session.

It's not a subscription. You pay once. Nothing recurring, ever.

It runs offline. No telemetry, no account required to use it.

Clean exit anytime. tare uninstall removes it; your ledger stays yours.

A subscription to save money is a contradiction.

You're already paying for the AI. Tare's only job is to make that bill go further — so charging you every month to do it would be its own kind of waste. One payment. Then it just works.

Tare

$49 once

Pay today, own it forever, v1.x updates included. The math stops here.

A typical SaaS add-on

$/mo · forever

Recurring charges that quietly outgrow whatever they saved you.

Checkout questions

Is this really one-time? +

Yes. One payment, no subscription, no renewal. Lifetime updates within the current major line (v1.x) are included in the price.

Can I try it before I pay? +

Yes — every install starts with a 7-day full-power free trial, no key required. Watch it save at least twice its price before you pay a cent. On day 8 it settles into a free measure-only mode; it never locks you out.

What do I get right after paying? +

A license key by email within seconds, and the success page shows a one-paste install with your key already embedded: curl -fsSL https://usetare.dev/install.sh | TARE_LICENSE=<key> sh. Run tare today to see your ledger.

Can I use it on more than one machine? +

Yes — the license covers up to 3 machines at a time. Deactivate a device and move the seat to another one you own whenever you need to.

How is tax / VAT handled? +

Polar is the merchant of record and calculates any tax/VAT at checkout, so you don't have to think about it.

What's the refund policy? +

You saw it work before you paid — but if something's wrong, email tare-support@agentmail.to within 30 days and we'll make it right. Refunds are administered by Polar as merchant of record. See the Terms for the full policy.

Why is it paid and not free / open source? +

The 7-day trial and the free measure-only mode already let you see your waste before paying a cent. The one-time fee funds the optimizations and lifetime v1.x updates without a subscription.

Buy it once.
Own it forever.

What happens after you pay

A subscription to save money is a contradiction.
