paperwork

Paperwork aims to be an open-source, self-hosted alternative to services
like Evernote (R), Microsoft OneNote (R) or Google Keep (R).

Paperwork is written in PHP, utilising the beautiful Laravel 4 framework.
It provides a modern web UI, built on top of AngularJS & Bootstrap 3, as
well as an open API for third party integration.

For the back-end part a MySQL database stores everything. With such common
requirements (Linux, Apache, MySQL, PHP), Paperwork will be able to run not
only on dedicated servers, but also on small to mid-size NAS devices
(Synology (R), QNAP (R), etc.).
