I'm creating a local-first DevOps workstation using Electron and Node, and I want to ensure that my licensing system is completely offline. This means no calls to a server every time the app starts up. I'm currently using a public-key signature for the license file, but I have concerns about users bypassing the verification check since the main process runs on JavaScript. I'm looking for advice on strong offline verification methods. Beyond just obfuscation, which has its limitations, how can I implement a more secure local verification? I've thought about moving the verification process to a native C++ Node add-on or using V8 snapshots. What's the best way to balance not requiring internet connectivity while maintaining solid license protection?

If you're looking for existing solutions, check out Keyforge. It's a licensing platform I've been working on that supports offline licensing with JWTs and includes a self-service customer portal. It could save you some time!
This is a tricky area! I'd recommend considering a contractual agreement for enforcement rather than relying solely on technical solutions. Offering a reward for reporting any misuse might help incentivize honesty among companies that use your software.
Using V8 snapshots could obscure your code structure, but keep in mind that determined users might still find ways to manipulate it. It's about finding the right balance between security and usability.
This sounds like a DRM issue. Make sure to explore the DRM features that your target operating systems offer. Another approach could be to integrate license validation into a self-update mechanism that runs when the user has internet access.
