If you need reverse engineering (code -> UML) and professional exports, StarUML is worth the license key investment. Frequently Asked Questions (FAQ) Q: Can I share my StarUML license key with a friend? A: No. The license is tied to your hardware + email. Sharing will result in the server revoking the key for excessive activations. Q: Does StarUML have a subscription? A: No. It is a perpetual license. You pay once until a major version upgrade (e.g., v5 to v6), which offers a 50% upgrade discount. Q: I found a "Universal License Key" on a blog. Will it work? A: 99.9% of those are fake. They either do nothing or are old keys from 2014 that the StarUML blacklist has banned. Q: Can I use StarUML offline after activation? A: Yes. Once the license file is installed locally, you can work without an internet connection for approximately 30 days before it requests a re-check.
