Solutions
We've seen it all, and we can help.
System Locker is the hub for your software business: licensing, authentication, resellers, protected automatic updates, advanced security, and more.
For the builder
Choose a proven licensing solution.
Your software is your expertise. Licensing is ours. System Locker answers the one question your app actually asks — “is this a paying customer?” — so you can focus on what you do best.
Choose the API that matches where your licensing code runs: the Simple API for a trusted central service, Bedrock for connected software on customer hardware, or Nightflyer when that software must keep working offline. Lock access to the right device and let Aegis monitor the logs. We'll handle the rest.
License desktop software
For the maintainer
Ship updates only paying customers can reach.
A ZIP on a public link is not a release strategy. You need a place to put files, and a way to control access.
Link Invisible Folder to your System Locker account and lock your downloads behind the same rules that gate your license. That's right: your customer's access is already proven by authenticating with System Locker.
Distribute software and updatesFor the defender
Catch shared keys, protect your revenue.
Hardware ID locking is a good starting point, but savvy users know how to work around it. Aegis monitors other signals to detect when a key is being used on multiple devices, helping you detect spoofed hardware identifiers.
Start with HWID locking so a key sticks to one device. Then turn on Aegis for IP intelligence and email alerts. When a key is flagged, check the authentication logs to investigate the activity.
Protect against key sharing
For the wise founder
Delegate responsibility: create reseller and admin accounts easily.
Resellers reach customers you would not reach alone. And hiring support personnel or admins can save you time, freeing you to focus on everything else.
System Locker's reseller portal allows the creation of limited-access accounts — perfect for granting key generation access to resellers, or HWID reset permissions for administrators. Create keys, manage existing customers, or handle a slice of support without compromising your personal credentials.
Run a reseller programFor the innovator
Your community lives on Discord. Meet them where they're at.
A lot of software businesses sell, support, and talk to customers on Discord. A small bot can take the repetitive work off your plate: whether it's issuing keys after a payment, looking up a key, or resetting a HWID.
Create a bot that calls the Management API after a webhook, a message from a staff member, or a chat command you define. What happens next is up to you, but System Locker makes it easy, regardless of your setup.
Automate licensing with Discord
Nightflyer lease
Bound to one installation
Authorize online
License and device verified
Keep working offline
20 minutes to 90 days
Proactive renewal
If online, authorization is refreshed
For the game dev
Keep paid customers working when the internet is not available.
An outage, a flight, or a restricted network should not lock a legitimate customer out. Our Nightflyer API authorizes once online, then gives the installation a signed lease your software can verify locally. It is perfect for single-player games that do not require an always-online connection.
Choose an offline window from 20 minutes to 90 days. We even launched a new plan designed to support viral distribution.

Still deciding?
It's free to take a test drive.
Create a test system, generate a key, and put a real authentication check around one feature before you go further. You don't have to commit to anything to see how System Locker fits — just see it work once.
