krpano Software License Overview

Part 5: Maintenance and Upgrade Pricing

krpano operates on a perpetual license + optional maintenance model.

Why maintenance matters: Web technologies change rapidly (e.g., the death of Flash, new WebXR standards, iOS updates). If you let your license lapse for two major versions, you may need to repurchase a full license to get compatibility with modern browsers.

Best practices for compliance and deployment

  1. Determine scope: Inventory domains, subdomains, and distribution channels before buying.
  2. Choose appropriate tier: Match license to expected deployments and client needs.
  3. Document purchases: Keep license agreements, keys, and receipts in a secure record.
  4. Secure keys: Don’t commit license keys to public repositories; use environment variables or server-side injection.
  5. Audit usage: Periodically verify deployments against license terms to avoid violations.
  6. Contact vendor for special cases: For white-labeling, embedding, or high-volume distribution, negotiate terms with krpano directly.

Unlocking the Full Potential of Virtual Tours: A Guide to krpano Licensing

If you’ve ever explored a high-end 360-degree virtual tour, chances are you were looking at krpano. Known as one of the most versatile and high-performance panorama viewers in the world, krpano is the engine behind countless professional virtual tour platforms. However, while the software is powerful, navigating its licensing structure is essential for anyone looking to deliver a polished, professional product. 1. The krpano License: Your Entry Ticket

The standard krpano License is required to use the software legally for production. Without it, your tours will display a prominent watermark and "krpano" branding in the viewer.

Core Functionality: Registering your license key allows you to process panoramas on your own server or locally without trial limitations.

One-Time Purchase: Unlike many SaaS platforms with monthly fees, krpano typically operates on a one-time payment model for the current version, making it a favorite for developers who want long-term control over their costs. 2. Branding Free License: The Professional Edge

For many creators, the standard license isn't enough. Even with a paid license, a "About krpano" link often remains in the viewer’s right-click context menu.

Removing the "krpano" Link: The Branding Free License is an additional add-on specifically designed to remove all visible references to krpano.

Prerequisite: You must already own a standard krpano License to purchase and use the Branding Free version.

Whitelabeling: This is essential for agencies and photographers who want to present the virtual tour as their own custom-built solution or offer a "clean" interface to corporate clients. 3. Why Invest in a License?

While there are free alternatives, professionals stick with krpano for several reasons:

Customization: If you are comfortable with XML, you can build entirely unique UI templates and interactions that go far beyond standard "click-and-move" tours.

Advanced Features: Access to powerful droplets, like "convert cube to sphere," helps you manage raw panoramic data and recover equirectangular images.

Performance: krpano is optimized for both desktop and mobile, ensuring smooth delivery across different devices. 4. Implementation and Deployment

Once you acquire a license, you can embed your panorama into various platforms. For instance, the WP krpano plugin allows you to use simple shortcodes like [krpano xml="file.xml"] to display tours within WordPress articles. For more advanced setups, developers often use krprotect to encapsulate files and protect their source code and panoramas before delivering them to clients.

Whether you are building a simple real estate walkthrough or a complex interactive exhibition, understanding these licensing tiers ensures your final product looks professional and remains fully compliant with the software’s terms of use. Wordpress Plugin: WP krpano - Forum

The Ultimate Guide to Krpano Licenses: Everything You Need to Know

If you are diving into the world of high-end 360-degree photography or virtual tours, you’ve likely encountered krpano. It is widely considered the most powerful and flexible panoramic viewer software available. However, unlike many modern SaaS tools, krpano’s licensing model is a bit "old school"—which is actually a great thing for your wallet.

Here is a comprehensive breakdown of the krpano license, what it costs, and why it remains the industry standard for professionals. 1. What is krpano?

Before discussing the license, it’s important to understand what you’re buying. Krpano is not a "drag-and-drop" software like many consumer tour builders. It is a highly customizable engine that uses XML and JavaScript to create immersive experiences. It allows for ultra-high-resolution images (multiresolution), complex hotspots, and deep customization that simpler platforms can’t touch. 2. The Krpano License Model: One-Time Purchase

The most attractive feature of the krpano license is that it is not a subscription.

No Monthly Fees: You pay once and own that version of the software forever.

Life-Time Usage: Once licensed, you can create an unlimited number of virtual tours for an unlimited number of clients without paying additional royalties.

Updates: Generally, minor updates and even many major version updates have been free for existing license holders for years, making it one of the best ROIs in the photography industry. 3. Types of Licenses

When you visit the krpano shop, you’ll typically see two main options: A. The krpano License (Standard)

This is the core license. It removes the "krpano.com" watermarks and enables the full functionality of the viewer and the "droplets" (the tools used to process your panoramas). Cost: Currently €129 (Euro).

Usage: Valid for one developer/user. You can install it on your workstation and laptop. B. The Branding Free License

By default, when a user right-clicks on a krpano tour, they see a "About krpano" menu item. If you want to remove this or replace it with your own branding, you need the Branding Free License. Cost: €29 (Euro).

Requirement: You must already own a standard krpano license to use this. It is an add-on, not a standalone product. 4. Why You Need a License

While you can download krpano for free to test its features, the "Demo Mode" has several limitations:

Watermarks: A "krpano" logo will be scattered across your panoramas. Functionality: Certain advanced features may be restricted.

Legal Terms: The free version is strictly for evaluation and testing. If you are getting paid by a client, a license is legally required. 5. Managing Your License

The licensing system is remarkably simple. Upon purchase, you receive a license code. You apply this code to your krpano tools (the krpanotools executable), and it "signs" the viewer files (tour.js or krpano.js) that you upload to your server.

Because the license is embedded into the viewer file during the "build" process, your viewers don't need to "call home" to a server to verify the license. This makes krpano tours incredibly fast and reliable for offline use. 6. Is it Worth It?

For hobbyists, the price tag might seem steep compared to free viewers. However, for professionals, it is a bargain.

White-labeling: You have total control over the look and feel.

Performance: It handles gigapixel panoramas that would crash other viewers.

Extensibility: If you can code it in HTML5/JS, you can integrate it into krpano. Conclusion

The krpano license is a "pro-grade" investment. It rewards those who want to move beyond basic templates and offer clients a truly custom, high-performance virtual reality experience. With no recurring costs and a one-time fee of roughly $140 USD (depending on exchange rates), it usually pays for itself after a single client project.

Title: The Virtual Tour That Almost Went Live

The Character: Sarah, a freelance web developer.

The Situation: Sarah landed her biggest client yet—a luxury hotel chain wanting an interactive 360° virtual tour for their new flagship property. She decided to use krpano, the powerful panoramic viewer.

Step 1: The Free Trial (The "Sandbox") Sarah downloaded krpano. It was perfect. She built a stunning tour with floor plans, hotspots, and a custom skin. She tested it locally on her computer. No watermark, no limits. "This is easy," she thought.

The Trap: She assumed that because the development had no restrictions, the live website wouldn't either.

Step 2: The Near-Miss She uploaded the tour to the client's staging server. Suddenly, a large, semi-transparent "krpano" logo appeared over every panorama. Zoom buttons displayed a "Demo Version" popup. Panning was blocked every 30 seconds.

Panicked, she checked the console. The message was clear: "License missing for domain use."

Step 3: Understanding the krpano License Rules (The Lesson) She finally read the official license carefully. Here’s what she learned:

Step 4: The Solution Instead of panicking, Sarah:

  1. Bought the correct license (krpano license for 1 domain: grandhotel.com – about €99 at the time).
  2. Dropped the krpano.license.js file (provided after purchase) into her tour folder.
  3. Re-uploaded. The watermark vanished. The popups stopped.

The Result: The client launched on time. Sarah learned to always purchase the license before deploying to a public server.
