Your computer is the cloud.

PierPulse turns one browser tab into a private file server. Choose a folder and share the code - guests browse, stream, download and edit straight from your disk over an encrypted peer-to-peer link. Nothing gets uploaded, and no account is needed.

Host

Share a folder

Your browser becomes the server. The tab stays open; the files stay on your machine - guests only ever see what's inside the folder you pick.

Sharing options

Guest mirroring

A guest who finishes downloading a file can help serve it to the next guest, instead of every copy coming from you. This also lets guests see that each other exist and connect to one another directly - off by default.

Full read-and-write hosting uses desktop Chrome, Edge, or Opera.

Dock at a pier

Have a code from a host? Enter it here to reach their folder from any browser.

The code is both the address and the key. Codes live only as long as the host's pier is open.

Pick a folder

The grant lives in this tab only. Nothing outside the folder is ever visible, and you can close the pier at any moment.

Share the code

The code is both the address and the key. Rotate it whenever you like - anyone holding an old code is locked out.

They dock

Guests stream video, read documents and - only if you allow it - save edits straight back into your folder.

What actually leaves your machine

A straight answer, because this app points at a real folder on your disk.

Files travel direct

Content moves browser-to-browser over DTLS-encrypted WebRTC. It never passes through or rests on any server - including ours.

One folder, no more

The host picks a single folder. That is the entire blast radius. Guests cannot enumerate or touch anything outside it.

Access you control

Guests get exactly the role you grant - view, download or edit - set per person, changeable live, revocable with one click.

A public signaling service introduces the two browsers to each other - like exchanging phone numbers - then steps out of the way. It sees two random IDs, never your files. Hosting is best on desktop Chrome, Edge or Opera; guests can use any modern browser. The host tab must stay open while guests are connected.
