Every public repository needs a LICENSE file — without one, most open-source conventions default to "all rights reserved" even if you intended otherwise. The challenge is that the popular open-source licenses have subtly different wording: MIT and ISC are short and permissive; Apache-2.0 has a long header plus an appendix that names the project; GPL-3.0 ships a heavyweight notice; MPL-2.0 scopes copyleft to individual files; BSD-3-Clause adds an explicit non-endorsement clause; and the Unlicense is a public-domain dedication rather than a permission grant.
This generator keeps the wording accurate for every supported license and fills in the three placeholders that always trip people up: the copyright year, the holder, and (where the license needs it) the project name. Apache-2.0 and GPL-3.0 both reference the project name in their generated text — leave the field blank to omit the optional appendix. The output is ready to drop into a LICENSE file at the root of your repository, no editing required.
Everything runs entirely in your browser — no upload, no signup, no telemetry. Your copyright details stay on your device.

Supported licenses
| License | When to use it |
|---|---|
| MIT | Permissive, short — the default for libraries and most npm packages |
| Apache-2.0 | Permissive + explicit patent license; common at large companies |
| GPL-3.0 | Strong copyleft — derivative works must also be GPL |
| ISC | Functionally equivalent to MIT, slightly shorter wording |
| MPL-2.0 | File-level copyleft — modifications to MPL files stay MPL |
| BSD-3-Clause | Permissive with a non-endorsement clause |
| Unlicense | Public-domain dedication, not a permission grant |
