Kerf pricing.
The core editor is free and the free tier isn't a trial — there's no timer and nothing to enter before downloading. Kerf Pro is $96/year, $10/month, or $149 for a lifetime license, with the same features on every plan.

Billing opens soonEverything in Free, plus the five tools below.
Kerf Pro isn't purchasable yet — we're still setting up checkout. Download the free editor today; once billing opens, you'll be able to upgrade from inside the app.
- One-click deploy to Vercel — from local folder to live URL without leaving Kerf.
- Snippet library — named HTML and CSS fragments you can insert in any project.
- Design token consolidation — a one-click merge of repeated CSS values into custom properties.
- Full accessibility audit — five WCAG categories with per-issue detail.
- React Native editor — component preview via react-native-web with click-to-source into the JSX.
Annual works out to two months cheaper than paying monthly. Monthly is the way to try Pro without a year's commitment, or to cover a single project. The $149 lifetime license is a single payment for permanent Pro access — no renewal at all.

Pricing FAQ
- Is the free tier really free forever?
- Yes. The core editor — click-to-source sync, Monaco, live preview, CSS hot-swap, framework detection, the layers panel, semantic editing, and visual property editing — costs nothing, needs no account, and has no usage limits. Features that ship in the free tier stay in the free tier.
- What's the difference between monthly, annual, and lifetime?
- The features are identical; only the billing differs. Monthly is $10 charged each month until you cancel. Annual is $96 charged once a year until you cancel, which comes to two months cheaper than paying month by month. Lifetime is $149 charged once, for permanent Pro access with no renewal.
- What happens if I cancel Kerf Pro?
- The free editor keeps working exactly as before. The five Pro tools lock again until you re-subscribe. A lifetime license has nothing to cancel.
- Do I need an account to use Kerf?
- Not for the free editor: download it and open a folder. Kerf Pro requires an account, because the subscription is verified against it.
- Is there a refund policy?
- Yes. Any Kerf Pro purchase — monthly, annual, or lifetime — can be refunded in full within 14 days. Email support and we'll process it.
- Can I use Kerf Pro on more than one machine?
- Yes. One license covers all your personal devices; we don't count machines as long as you're the one using them.
- Do you offer team or volume pricing?
- Not yet. If you need five or more seats, email support and we'll sort something out.
- Does annual auto-renew?
- Yes. Annual renews at $96 each year until you cancel, and canceling keeps Pro active through the period you've already paid for. You can switch between monthly and annual from your account.
- Can I buy Kerf Pro right now, and how will upgrading work?
- Not yet — the price is set, but checkout isn't live, so Pro shows as "Coming soon." When billing opens, upgrading happens in the app: clicking any Pro tool brings up a prompt with the monthly and annual options.
