What each license actually means — in plain English. 11 licenses documented.
Do whatever you want. Just keep the copyright notice.
Like MIT, but with an explicit patent grant and contribution terms.
Use freely, but if you distribute modifications, you must release your source code under GPL too.
Like GPL, but the copyleft extends to network use. If you run it as a service, you must share your source.
Almost identical to MIT. Keep the copyright notice, that's it.
Copyleft for the library itself, but you can link to it from proprietary code.
Source code is visible but you cannot use it commercially as a competing service. Converts to open source after a set date.
File-level copyleft. Modified files must be shared, but your other files can be proprietary.
Do whatever you want. Keep the copyright. Don't use the author's name to endorse your product.
Functionally identical to MIT but shorter. Do whatever you want, keep the copyright.
Public domain dedication. No restrictions whatsoever — not even attribution required.
