Ephemeral browser sharing

Share a logged-in browser.
Never your password.

Hand a friend temporary, time-limited access to a browser that's already signed into your account. They control the screen over a live stream — your credentials never leave the server. When the timer ends, access revokes itself.

Forgot password?

Your session token is kept only in this browser tab. Passwords are hashed (scrypt) server-side.

  • Guests get an opaque token — never a password
  • Use packs: e.g. 5 uses × 15 min each
  • Revoke any session instantly
See it in action

From login to auto-revoke.

A single-use link, a live screen, a ticking timer. Watch the whole lifecycle.

  1. Already signed in

    Your browser holds the login — it never leaves the server.

  2. Mint a timed link

    One click creates a single-use link with a TTL.

  3. Guest connects

    They watch & control the screen — over video, no password.

  4. Auto-revoked

    The timer ends and the session is torn down.

The problem

Sharing an account usually means sharing your password.

That hands over the keys to your whole account — and parallel logins from one credential trip fraud and concurrency detection. There's a safer way.

The old way

Hand over the password

  • They can see and change your real credentials.
  • No expiry — access lasts until you reset the password.
  • Two simultaneous logins → flagged, locked, or banned.
  • No way to claw access back once it's out.
VS
With SubShare

Send a single-use link

  • Guests see only a video stream — no credentials, ever.
  • Every link is time-limited and dies on its own.
  • One profile, one guest at a time — no concurrency flags.
  • Revoke instantly from your console.
How it works

Pixels travel. Passwords stay put.

SubShare wraps Neko, which runs a real browser in Docker and streams only audio & video over WebRTC.

1

Sign in once

Log into your account inside the streamed browser. The profile is saved in a private Docker volume.

2

Mint a link

Pick a duration. SubShare generates a single-use link your friend can open in any browser.

3

Auto-revoke

When the timer ends — or when you click revoke — the session is torn down and the link dies.

Built for safety

Everything you need, nothing you don't.

Zero credential leakage

Guests receive an opaque, single-use token — never your password or the account URL.

Auto-expiry

Per-session timers tear down access at the TTL, and survive a backend restart.

Single-use links

Each link works exactly once. Replays and expired links are rejected outright.

Concurrency-safe

One profile, one guest by default. Overflow requests are rejected to dodge fraud flags.

Instant revoke

Kill any live session from the console — the Neko session is deleted immediately.

Self-hosted

Runs on your VPS with Docker + Caddy and automatic HTTPS. Your data stays yours.

Share access, not your password.

Open the console, mint a time-limited link, and send it over. Revoke anytime.
