Zovo Pro
Every Zovo extension is free and stays free. Zovo Pro adds extra tools to the Zovo viewers, USD 19 once for life, or USD 59 once for a team of 5. Each Pro tool works 3 times before you pay.
Zovo is made by BeLikeNative. The card page says "Pay BeLikeNative", and your card statement shows ZOVO PRO.
Before you pay
- Try first. Each Pro tool works 3 times on your computer, with no key and no account.
- Free stays free. No feature that has shipped as free will move behind Pro.
- USD 19 once for one person, for life, in every Zovo extension that has Pro tools. USD 59 once for a team of 5 people who share one key. No subscription.
- Card payment through Stripe, with no account. Apple Pay, Google Pay and Link show up where your browser offers them.
- Nothing about Pro shows when you open a file. No startup popup, no countdown, no banner.
How the key arrives and where it goes
- Pay by card. The next page shows your license key, which starts with ZOVO1., and a "Copy key" button. Keep that link; it shows the same key again.
- Go back to VS Code, Cursor or Windsurf. In the Zovo Pro window of any Pro tool, click "Enter a key". Or open the Command Palette (Ctrl+Shift+P, on a Mac Cmd+Shift+P) and run "Zovo Pro: Enter Zovo Pro license key".
- Paste the key. It is checked on your computer, with no network call. Pro turns on at once in every Zovo extension on that computer.
A team key works the same way. Pay USD 59 by card, and each of the 5 people pastes the same key.
Other ways to pay
- GitHub Sponsors. Pick the "$19 one time" tier on GitHub Sponsors, then pick "Unlock with GitHub Sponsors" in the extension and sign in with the same GitHub account. A monthly sponsorship of USD 10 or more that is still running counts too.
- PayPal. Send USD 19 to www.paypal.com/paypalme/najzzz/19 (USD 59 for a team, www.paypal.com/paypalme/najzzz/59) with "Zovo Pro" in the note. The key comes by email within a day, to the address PayPal shows us.
- Team of 5 on GitHub Sponsors, the "$59 one time" tier. The key comes by email within 24 hours.

Questions before you buy
Ask first. Open an issue on GitHub with your question, and the answer comes there. The issue is public, so do not post your email address or a key.
Need your format supported?
Open a format request with a sample file, and I reply there whether it can be done. For USD 299 once, through this GitHub Sponsors tier, I add your file format or a missing feature to a Zovo viewer, with tests, within 7 days.
This is separate from Zovo Pro. Zovo Pro adds ready-made tools for everyone. Custom format support is work for you: a format or feature you need, added to the free viewer for every user, so it stays free there too.
Questions
Who sells Zovo Pro?
Zovo is made by BeLikeNative. The card page says "Pay BeLikeNative", and your card statement shows ZOVO PRO. The payment runs through Stripe.
Will anything that is free today become paid?
No. Every feature that has shipped as free stays free, in every later version. Pro only adds tools on top.
How much is it, and is it a subscription?
USD 19 once for one person, for life. USD 59 once for a team of 5 people who share one key. No subscription and no renewal.
Can I try a Pro tool first?
Yes. Each Pro tool works 3 times on your computer with no key and no account. The row under the toolbar shows how many tries are left.
How does the key arrive?
After a card payment the next page shows your key, which starts with ZOVO1., and a "Copy key" button. The same link shows the key again later. With PayPal or GitHub Sponsors the steps differ; see "Other ways to pay" above.
Do I have to enter the key in each extension?
No. Enter the key once. Pro turns on in every Zovo extension on that computer. On a second computer, enter the same key there.
Does the extension call home?
No. The key is checked on your computer, with no network call and no account. No tracking and no telemetry. The only network request is one GitHub check, and only if you pick "Unlock with GitHub Sponsors".
Does it work in Cursor, Windsurf and VSCodium?
Yes, with a key. The extensions install there from Open VSX, and the key check runs on your computer.
Can I pay without a card?
Yes. Pick the "$19 one time" tier on GitHub Sponsors, or pay USD 19 by PayPal (USD 59 for a team by PayPal) with "Zovo Pro" in the note and get a key by email within a day.
I lost my key.
Open the link of the page that showed it, or reply to the email that brought it. You can also open an issue without posting the key.
Will I see ads or popups?
No. No startup message, no countdown and no banner. A Pro tool asks for a key only when you click it after its 3 free tries.
Does Pro cover the JetBrains plugins?
No. Zovo Pro is for the VS Code extensions. The JetBrains plugins are separate.

Support this work
Zovo builds and maintains every tool on this site. If one saves you time, you can support the work on GitHub Sponsors. Monthly tiers start at $5, and one-time tiers start at $15. Sponsorship is optional, and the tools work the same without it.
