A simple bookmarking engine

This is a small python3 API and website that allows saving bookmarks into an SQLite3 database.

The production environment will eventually be hosted at save.c0de.link

Completed Features:

Database - Capable of any user-defined database file (multiple instances); Has Create/Read/Update/Delete methods for bookmarks

Authentication - I'm thinking about using Telethon which will send me auth tokens, which would then be sent along with the request
Website UI - I want the website to be extremely easy to use. I plan on using Bootstrap 4 with a style very similar to lob.li
API - Able to accept various HTTP methods (POST, GET for sure, possibly PUT and DELETE). This will interface with the database, and provide data sanitization. I'm planning on using Bottle to accomplish this
Chrome Extension - This will allow exporting bookmarks from Chrome into this service, as well as quickly adding pages, most likely through a right click menu and by clicking on the icon
Firefox Extension - Everything the Chrome extension can do
