Protection with rename, string encryption, control-flow flattening, bytecode VM, CSS embedding, domain lock and expiration date. In this version, the OJS7 award is available for free.
This unlocks: Domain Lock, Expiration Date and lets you embed CSS into the output. These are injected before your code is sent to Nebula for obfuscation — separate from your Nebula account/usage limit above. In this version, the Premium is active for free.
This tool sends your code to the Nebula obfuscation API. It helps:
What Nebula applies when each option is on:
Nebula account access (top of the page): raises your daily obfuscation quota. Buy a key via Gumroad and activate it above — same account as nebula.us.kg.
Local premium (client-side): a separate local key that unlocks Domain Lock, Expiration Date and CSS embedding. These are plain JS guards prepended to your source before it's sent to Nebula.
Q: Is my code sent to a server?
A: Yes — your code is sent to the Nebula obfuscation API to be processed, and is not stored beyond that request.
Q: Do I need an account?
A: Yes, sign in with Google above. New accounts get a free daily quota; a Nebula license raises it.
Q: Where can I learn more about Nebula?
A: Visit nebula.us.kg.
