Pastebin Alternative — No Signup, Optionally Encrypted

Most Pastebin clones gate the useful features behind a signup, throw ads at the paste page, or make every URL public by default. Clipcroft is a different shape: a real-time clipboard you open on two devices, type a name, and paste into. No account, no email, no public URL — and an optional password makes it end-to-end encrypted.

How this differs from a classic Pastebin

Pastebin and its clones (paste.ee, hastebin, ix.io, dpaste, gist) are public-by-default URL containers. You paste text, you get a URL, you share that URL, the recipient opens it. Privacy varies — some support unlisted, some support burn-after-read — but the mental model is "the paste lives on the server, addressed by URL".

Clipcroft is a clipboard, not a URL container. The text lives in the browsers that joined the clipboard, not on a server. The "URL" you'd share is just the clipboard name, and the other device pulls the content live as soon as it joins. There is no public paste page. There is no scrape-able URL.

The trade-off is that both devices need to be online when the text is pasted (or shortly after). For genuinely asynchronous "leave a paste, link it tomorrow" sharing, a classic Pastebin is the better tool. For "I have text on my phone and need it on my laptop right now", Clipcroft is faster and more private.

Why "no signup" matters

Most Pastebin services let you paste anonymously, but the useful surface — paste history, syntax highlighting, expiry control, private pastes — is gated behind an account. The Pastebin home page is also adversarially monetised: heavy ad rails on the paste view, anti-adblock interstitials, "premium" upsells. None of this is necessary for what you came to do, which is move text between two devices.

Clipcroft has no account because it doesn't need one. The clipboard name is your session identifier, the browsers do all the storage, and the only server-side state is the live signaling connection. Once the browsers disconnect, there is nothing left on our side that even hints you used the service.

Optional end-to-end encryption — like PrivateBin, simpler

For sensitive snippets — credentials, tokens, internal config, anything you wouldn't want sitting in a server log — set a clipboard password. Once set, the clipboard becomes a private pastebin: AES-GCM encryption with a key derived from your password using PBKDF2, all in the browser. The server only ever sees ciphertext, and the key never leaves either device.

This is structurally similar to PrivateBin's URL-fragment-as-key pattern, with one ergonomic difference: instead of handing someone a long random URL, you pick a memorable password and split the channels — clipboard name through one path, password through another. See the password-protected clipboard guide for the full security model.

Common use cases

Code snippets between dev machines

You're testing on a remote box and need a one-liner from your laptop. Paste it into the clipboard, paste it out on the other side. Faster than committing to a scratch repo, no Pastebin URL trail.

Logs from a colleague's machine to yours

A colleague hits a stack trace. They paste it into a shared clipboard, you paste it out on yours. End-to-end encrypted if they bother to set a password — but in any case, the log doesn't go up to a public Pastebin URL that gets indexed somewhere.

Magic-login URL or one-time code from phone to PC

Hit a "we sent you a login link" email and you only have the inbox open on the phone? Paste the URL into a Clipcroft clipboard with the same name open on the PC, and click it from the laptop — without forwarding mail or messing with mobile-PC handoff features. See sending a link between devices.

Notes-to-self across devices

Treat one named clipboard as your private scratchpad. Anything you paste lives in the browsers' local storage, expires after 3 days by default, and can be password-protected if you want even the relay to be encrypted.

Frequently asked questions

Is Clipcroft a Pastebin alternative?

Yes, for the share-text-between-devices use case. Open clipcroft.com on both devices, pick the same short clipboard name, and paste text. The other device shows it instantly. No signup, no email, no app — and unlike Pastebin, the text isn't a public URL by default.

Do I need an account?

No. Clipcroft requires no registration, no email, no account password. (There's an optional clipboard password for encryption, see below.) The clipboard name is the only thing you need to share between devices.

Is the text public, like a Pastebin URL?

No. There is no public URL for your paste. Anyone with the same clipboard name can join, but the name is something you choose and share only with your other devices or the people you want. For genuinely sensitive content, set an optional clipboard password — that turns on AES-GCM end-to-end encryption with a key derived in your browser.

How long is the text kept?

Items live in the browser's local storage on the devices that joined the clipboard, for 3 days by default. The retention window is configurable. Nothing persists on Clipcroft's servers — the server only relays small text messages momentarily so they reach the other browser.

Is there a length limit?

Short text relays through the server (subject to the standard 256 KB cap). Larger text is sent peer-to-peer via WebRTC the same way file uploads are. In practice you can paste anything from a one-line URL to multi-megabyte logs without hitting a hard limit.

Can I use it for code snippets?

Yes. Paste any text, including code. There's no syntax highlighting (Clipcroft is a clipboard, not a code-review tool), so for code you want to read on the destination device, copying it back into your editor will give you the right rendering.
