PasteLite

Very lightweight and simple paste service. Can support any type of file configured, and can display in HTML, raw text, or JSON. Pastes can automatically expire after a set time.

Written in typescript and using Fastify & Handlebars, PasteLite is a fast, simple, and lightweight tool to just allow without registration users to paste content and retrieve it simply.

Pastes are stored using sqlite into a pastes.db file
