Resin 1.2 is released under the Caucho Developer Source License. Caucho Technology is committed to providing the best web tools for all developers, from hackers to multinational corporations. We've created the Developer Source License to meet that goal. Developer Source ensures that everyone has access to Resin. It also ensures that we can continue to develop and support the highest quality web development software.

For information on deployment licenses, see our sales page.

You may use Resin for development, evaluation, and demos.
You must contact us 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.
