Liferay vs. Commercial Products

  • Innovation - In its 9th year of development, Liferay boasts a history of innovation among both commercial and open source products.
  • Low TCO - Liferay provides the lowest total cost of ownership with ZERO license fees.
  • High ROI - Use your existing IT investment! There is no application server agenda and no pressure to pay for toolsDevelop portlets with a full featured IDE like Eclipse, Netbeans, and JBuilder or with lightweight editor like EditPlus, VI, and Emacs.
  • Freedom & Flexibility - Open source means the code is in your hands. If you want to customize it, you can. If there are security flaws, the community can participate in fixing it quickly.
  • Security - There is actually less risk in going with a sustained open source product than in going with a commercial vendor. Vendors can go out of business. Vendors can merge and render your product dead in the water. A sustained open source product like Liferay Portal has an active community around it that works together.

Liferay vs. Open Source Portals

  • Market Leadership - Liferay is the leader in downloads (over 60,000 per month) among ALL open source Java portals.
  • Principle - Not all open source licenses are created equal! Some require modifications to be contributed if you choose to sell or distribute your product. Some still charge a license fee for commercial use.
    Liferay is open source because we believe it is the next step in the evolution of software development and chose the liberal MIT license accordingly.
  • Maturity - Liferay has one of the most mature and active open source communities as evidenced by our active forums.
  • Stability - Aside from our impressive community, there is a real company behind the product driving product development.
