ZLM.

simple and easy-to-use software license management

10 reasons why ZLM is the right license manager for you:

1. dead simple API

It is very easy to integrate ZLM into your project, see the documentation for an example. Different licensing schemes can be set in the license files and not with different API calls. You can integrate ZLM in your product once and then forget about it!

2. eco-friendly library

The ZLM library is very eco-friendly:

3. no hustling, no dependency

We do not hustle with you over the price and make you dependent on us by yearly contracts.

Our pricing policy is very simple: You pay $999 (USD) once and you can use the current ZLM release (and all upcoming minor releases) forever, for as many products and as many customers you want! This makes ZLM a risk free purchase, we do not lock you in with a yearly contract which might get more expensive over the years.

In contrast to many competitors you do not have to pay anything from the second year on!

4. no legalese

We hate legalese as much as you do and we trust our customers, therefore we do not make you sign lengthy legal agreements before you can start coding. Instead we have very simple EULA with which you can agree by a simple click when you buy the product online.

You can buy your ZLM license in less than 5 minutes!

5. try before you buy

You can try ZLM out right now for 30-days (free of charge, no strings attached). We do not make you fill out big forms or talk to sales reps beforehand.

Get started with ZLM in 5 minutes!

6. strong cryptography

To make the license files used by ZLM basically unforgeable we use the Digital Signature Algorithm (DSA) with a key length of 2048 bits in combination with the SHA-256 hash function, thereby following the recommendations for secure digital signatures of the National Institute of Standards and Technology outlined in NIST 800-57.

Don’t settle for anything less than the industry standard!

7. rock-solid software made in Germany

As German software engineers we have a strong focus on software quality which borders on OCD. We go to great lengths to make sure that ZLM solves your problems and doesn’t cause you more:

We obsess for your success!

8. guaranteed bug-free

In fact we believe in the quality of our software so much that we guarantee to pay you a 0.1 Bitcoin finders fee if you are the first person who reports a reproducible bug.

Of course, we also fix any such bugs free of charge!

9. tamper resistance

ZLM is three-fold tamper resistant:

Most competitors lack these features!

10. ZLM is made by developers for developers

ZLM was born out of unhappiness with existing license managers. As developers we didn’t want to read lengthy EULAs, fill out forms, or talk to sales reps before even looking at an API or getting a quote.

With ZLM we cut the crap and let you go back to coding fast!

It takes less than 5 minutes to buy ZLM now (pay $999 (USD) once and use ZLM forever)! You can also try out ZLM for 30 days completely free of charge before you make a decision.

If you have any questions or special needs for your license management (for example, you want to use ZLM on an embedded platform, you miss critical functionality in the API, or you need special language bindings), please talk to us! We are happy to hear from you!
