is a self-hosted video CMS for building, managing and monetizing video websites and platforms.
A great video project starts with an idea.
KVS gives you everything you need to bring it to life.
KVS has been continuously developed since 2009.
Our public development history provides a complete dated log of every release, new feature, improvement, and fix from 2009 to today.
KVS powers more than 14,000 video websites — from compact niche projects to high-traffic platforms and multi-site networks.
Its flexible architecture lets you expand your content library, audience, and infrastructure without extensive code modifications.
Established and growing video projects choose KVS or migrate to it from other platforms.
KVS gives website owners the flexibility to adapt their content, infrastructure, design, and monetization model as their projects evolve.
KVS is engineered for fast page generation and efficient use of server resources.
Performance has been a priority since the first version, and every new release continues to improve efficiency for modern technologies and growing workloads.
Distribute video storage, delivery, and conversion across multiple servers as your project grows.
Use dedicated storage and conversion servers, S3-compatible storage, CDN services, and KVS Conversion Cloud to build an infrastructure that fits your workload.
Since 2009, KVS has delivered more than 70 major updates and over 1,200 improvements.
New features and improvements remain available to both existing and new projects through updates, helping long-running websites keep evolving without rebuilding on another platform.
KVS support is provided directly by the programmers who develop the product — never outsourced to third-party operators.
Every KVS package includes free installation on a server configured according to KVS requirements and free product support, with practical guidance and advice from the development team.

We use KVS on several sites with more than 1 million page views a day. It has consistently handled the load, and support has been quick and helpful. That experience is one reason we keep choosing KVS for our new video projects.
— Croco, Croc Network
Choosing KVS meant we did not have to build our video site from scratch. Our previous script could not handle the load, and custom development would have taken months and cost thousands of dollars. After buying and testing KVS, we found a more stable, more affordable solution, backed by knowledgeable support.
— Noterbe
We have used KVS for several years and are gradually moving our major sites to it. We value the combination of content management features, a practical admin area and an easy-to-use template system. Together with professional support, these are the reasons we confidently recommend KVS.
— SP Support, Serious Partners
My site started as a small side project on the basic version of KVS and grew to over 1 million page views a day. It handles that load with one powerful main server and several storage servers, using multi-server support and two-level caching. Having seen this work, I feel much more confident when traffic grows.
— Pikasso, video website owner
We build video websites for clients and use KVS for most of them. We can customize templates, offer free and paid access, and assign admin permissions across the team. The same platform works for both standard sites and more complex projects with member areas.
— Art Design, video website development
Before buying, I explored the admin demo and documentation because KVS seemed complicated at first. Looking closer, I found many of the features I needed were already there and I could customize the site to suit my project. I bought it and haven't regretted it. The features are well thought out, and support gives quick, clear answers.
— Arthur (SteelArt), KVS user
We use KVS to run several Royal Cash websites. Site management and configuration are straightforward, pages load quickly, and server load stays low. The KVS team also helped with installation and configuration for our projects, which we really appreciated.
— RC Support, Royal Cash
Our experience with KVS at Bravo Media Group has been positive from day one. Regular updates bring new features, and the software is flexible enough to adapt to our needs. Support is timely and helpful with both small questions and more complex issues. That combination is something we particularly value.
— Alex, Bravo Media Group
We have worked with KVS for several years. What stands out is the balance between ease of use, flexible customization and a strong set of features. It gives us the freedom to adapt a video website to our needs while keeping it practical to manage.
— CEO, Tube Alliance
KVS was straightforward to get running and easy to use once configured. I usually worry about spending days fixing problems when trying a new script, but that was not my experience here. The ease of use really stood out, and it is the reason I recommend KVS.
— IF, Idol Bucks
What I like about KVS is how many features it offers and how flexibly they fit together. It feels like a set of building blocks you can combine to create the video site you have in mind. That flexibility is what makes the software stand out for me.
