Sample Home Page

This is the default index.xtp page for the Resin web server. If you see this page while browsing, it's because the site owner hasn't bothered creating his own home page yet.

Developer Source Licensing

Resin 2.1 is commercial software released under the Caucho Developer Source License. Commercial and other paid users must purchase deployment licenses, allowing us to develop and support the highest quality web application software.

Caucho Technology is committed to providing the best web tools for all developers, from hobbyists to multinational corporations. We've created the Developer Source License to meet that goal. Developer Source is a commercial license that ensures everyone has access to Resin.

For information on deployment licenses, see our sales page.

  • You may use Resin for development, evaluation, and demos.
  • You must to purchase a deployment license if either:
    • You are paid to use Resin.
    • You are paying someone else to use Resin.
  • If no one is paid to use Resin, you may use Resin for deployment:
    • students
    • private use
    • tiny startups with neither funding nor income.
  • Anyone falling in between should contact us for a waiver.
  • Distributors must contact us.
  • If you are allowed to use Resin, you may modify the source for that use.

Congratulations! Resin is working.
