OneSocial

Write once — publish to your own social accounts in one click.

What it does

OneSocial is a browser extension for individual creators. You write a post, add photos or a video and click “Publish”: OneSocial sends it to each of your connected accounts through that network's official API, in the format the network expects (text length, tags, links, media limits). Before you click, every network shows exactly what will be posted and what it won't accept.

How it works

Install the OneSocial extension in a Chromium browser (Chrome, Vivaldi, Edge).
Open “Networks” and connect each account: you sign in on the network's own page and allow OneSocial to publish. Your password never reaches OneSocial.
Write the post, add media and click “Publish”. Nothing is ever posted without that click: no scheduling, no automation, no bulk posting.

For TikTok, you choose who can see each post and whether comments, Duets and Stitches are allowed — OneSocial shows only the options your TikTok account permits and sets none by default. For YouTube, OneSocial uploads your vertical video to your own channel as a Short.

Your data

Access tokens stay only in the extension on your own device. Our server keeps no database of users or posts: it only handles sign-in returns, exchanges sign-in codes where a network requires our app secret, and — for Instagram, Threads and TikTok photos — holds a file for a few minutes so the network can fetch it (deleted after publishing, and automatically within 24 hours). Details: Privacy Policy.

Access

OneSocial is licensed: you sign in with Google, and access is granted by the licence owner. If you were given an access code, enter it on the extension's start screen.
