One licence. One price. Everything in it.
There is no cheaper tier with the interesting part removed. The tool that encrypts your DSP constants is the reason to buy Seatlock, so it is in the only thing you can buy.
| Seatlock | |
|---|---|
| Founding price | $249 once — until 30 November 2026, or the first 50 licences, whichever comes first |
| List price after that | $349 once |
| Updates | 12 months included. After that, $99/year if you want to keep receiving them. |
| If you never renew | Your licence keeps working, forever. You simply stop getting new versions. |
| Per-sale fee | None. Ever. |
| Your customers’ data | On your server. We never see it. |
Seatlock 0.1 is built and tested on macOS. Windows support is written and is the next release, included in your updates at no extra cost — founding customers get it the day it ships.
What is included
- The licence server for your own WooCommerce shop, under the GPL.
- The C++17 SDK and the JUCE module.
- seatlock-tool, which encrypts your DSP constants into your build.
- A worked example plugin that builds as VST3 and Standalone, so your first integration is a diff and not a blank page.
- Unlimited products, unlimited licences, unlimited machines. We do not count your customers, because we cannot see them.
- One production shop. Staging and development copies are free.
- A one-command importer if you are moving from another licence manager, and a compatibility layer so builds you have already shipped keep activating.
- E-mail support from the person who wrote it.
Switching from another licence manager?
Send proof of your existing licence to support@seatlocklicense.com and the founding price is $199. The importer moves your existing keys, customers and activations in one command, and old builds of your plugins keep working while you migrate product by product.
What this costs compared with a revenue share
Licensing services that take a percentage are cheap until they are not. At 5% of sales you pay more than Seatlock’s entire price once you have sold about $5,000 of plugins — and then you pay it again every year, forever.
| Your plugin sales in a year | A 5% service | A 10% service | Seatlock |
|---|---|---|---|
| $5,000 | $250 | $500 | $249 once |
| $20,000 | $1,000 | $2,000 | $249 once |
| $50,000 | $2,500 | $5,000 | $249 once |
Those services also hold your customer list. Seatlock never sees it.
Questions people ask before buying
Is there a trial? There is a live demo of the whole system, with the admin screens and a customer account, and you can click anything in it. The SDK is C++ you compile yourself, so the honest way to evaluate it is the demo plus the documentation, and Paddle’s 14-day refund if the answer turns out to be no.
What happens if you stop working on it? The licence server is GPL, so it is yours whatever happens to me. It runs on your hosting, with your database. Nothing phones home, and no service of mine has to be alive for your customers to activate.
Do I need WooCommerce? Today, yes — the server is a WooCommerce plugin. If you sell through Paddle, Stripe or Lemon Squeezy instead, tell me: a webhook endpoint that issues licences without WooCommerce is the next thing after Windows.
Can I see the source? The licence server, yes — it is GPL, and the whole plugin is in the package. The SDK and the tool ship as source too, under the commercial licence, so you can read every line that goes into your product. What you cannot do is redistribute them.
Who is behind it? One person: Mesut SAYGIOĞLU, in Antalya, Türkiye. Seatlock was built to license my own audio plugins, and it does. The Contact and Legal Notice page has every registration detail.
