Install Replyburst in 30 seconds

One click to add the extension, sign in on X, and you’re growing. Here’s the whole thing.

Get the extension

On the Chrome Web Store — launching soon.

  1. STEP 1

    Add it to Chrome

    Click the button below to open the Replyburst listing on the Chrome Web Store, then hit “Add to Chrome.” Works in Chrome, Brave, Edge, and Arc.

  2. STEP 2

    Pin the icon

    Click the puzzle-piece icon in your toolbar and pin Replyburst, so it’s always one click away.

  3. STEP 3

    Open X and sign in

    Go to x.com logged into the account you want to grow, click the Replyburst icon, and hit “Sign in with Replyburst.” We detect your account automatically — nothing to copy.

  4. STEP 4

    Start engaging

    Your account shows up in the dashboard. Set your voice, then review AI-drafted replies in the Engage deck — or flip on automation.

Is it safe?

Yes. Replyburst posts through your own logged-in browser session — never the X API and never a bot server — with human-like, randomized delays. Nothing is posted without your approval unless you turn on automation yourself. The extension only runs on x.com and your Replyburst dashboard.

Installing the beta manually?

If we sent you the beta package before the store listing is live:

  1. Unzip the Replyburst package we sent you.
  2. Open chrome://extensions.
  3. Turn on Developer mode (top-right).
  4. Click Load unpacked and select the unzipped folder.
  5. Then follow steps 2–4 above.
