Botd vs dead-drop

BotD is FingerprintJS's open-source, MIT-licensed JavaScript library that runs entirely in the browser to flag basic automation -- headless Chrome, PhantomJS, Selenium, and similar tools -- without any server round-trip for the detection itself. It ships as an npm package or as a CDN-hosted ES module and returns a plain detected/bot-kind result object from a single detect() call. It is free for any use with no signup; FingerprintJS separately sells a more sophisticated, paid, server-side Bot Detection API for teams that need those extra signals.

dead-drop is a minimal, self-hostable API for sharing ephemeral secrets: the client encrypts the payload before it ever reaches the server, so the backend only ever stores ciphertext it cannot read, and each secret can be set to self-destruct after a single view or a time limit. It needs no account or API key — requests are simply rate-limited per IP — and returns plain JSON over a small REST surface. The design mirrors the classic one-time-secret pattern used for sharing passwords or tokens without leaving a permanent copy anywhere.
