Letterbox

Ready-to-run paste backend for apps, bots, and automation workflows

PlatformWebfree

Letterbox is a free, ready-to-run paste backend that developers can drop into apps, Discord bots, Telegram bots, and automation workflows, adding shareable, password-protected, expiring paste links without building the backend from scratch. It's built for developers who need paste functionality inside their own app or bot, not a standalone paste website.
