Yes, if you have a "top" developer license, you can install it on up to three machines (e.g., Work, Home, Laptop) provided you are the sole developer.

Ideal for freelancers or solo developers. Small Group (up to 4 Developers): Suitable for small teams.

Once you decide to purchase a license through the Chilkat website (via MyCommerce or PayPal), you will receive a valid, non-trial unlock code. This code will look similar to a structured string, such as SAMPLE.CB1072019_abcd7tqxyzz... , which contains an embedded month and year (e.g., July 2019) indicating the version of the SDK your key is valid for.

To activate your library, you typically call an UnlockComponent method (or similar, depending on the language) at the start of your application. : global.UnlockBundle("YOUR_UNLOCK_CODE")

Purchasing a Chilkat license is straightforward. You can visit the official “Buy a Chilkat License” page, where you choose your licensing level (1, 4, or 8 developers) and then proceed to payment via Stripe or PayPal. Once the transaction is complete, you will receive an email containing your permanent unlock code. That code is valid immediately; you can start using it in your application as soon as you receive it.

While Chilkat is a powerful all‑in‑one solution, it is worth noting that some developers have considered alternatives. For a specific, narrowly scoped need (e.g., only SMTP email sending), there may be open‑source libraries that are free of charge. However, for developers who need a consistent, cross‑platform API across many different protocols and who value having a single, well‑supported commercial product, Chilkat is often the right choice. The key is to evaluate your own requirements: if you need a wide range of network and security features, the Chilkat Bundle is typically less expensive and less time‑consuming than assembling and maintaining a dozen separate open‑source libraries.

Once you apply your license, you gain access to the features that make Chilkat legendary:

You don't need a purchased key to start testing. All non-free Chilkat components can be unlocked for a by calling a specific method once at the beginning of your program:

const chilkat = require('@chilkat/ck-node23'); function initializeChilkat() let glob = new chilkat.Global(); let success = glob.UnlockBundle("Your_Purchased_Chilkat_Key_Here"); if (!success) console.log(glob.LastErrorText); return false; return true; Use code with caution.
