Why it's a strong pick

SocialBu gives you a full composer in the browser, with control over which accounts get each post and how the text reads on each platform. That suits people who manage several accounts. The trade-off is the free plan: it has tight limits on accounts and posts, so it may work more as a trial than as an ongoing free scheduler.

What it does

Open the composer from any website with one click, or from the right-click menu. Select one or more accounts, including specific team or client accounts. Edit the text for each platform, with emojis, hashtags and Canva designs. Preview the post, then schedule it, publish now, save a draft or add it to the queue.

Key features

One-click composer. Open it from the toolbar or the right-click menu.
Account targeting. Pick team or client accounts per post.
Per-platform text. Change wording, emojis and hashtags for each platform.
Previews and formats. Preview posts, with options for stories, reels or shorts.
Four ways to send. Schedule, publish now, save as draft or add to queue.

Who it's for

SocialBu's extension suits agencies and teams that manage client accounts and want to control where each post goes. It is a weaker fit if you want a free scheduler to use every month.

Do I need a SocialBu account?

Yes. The store listing says you need a SocialBu account, so there is nothing to post to without one. SocialBu's pricing page lists a free plan with limits, plus a trial. It also has paid plans. Check the vendor's current limits before you commit to the free plan.

Can I send different text to each platform?

Yes. The store listing says you can customize the text per platform, including emojis, hashtags and Canva designs. You can preview the post and choose options such as stories, reels or shorts before you send it. You can then schedule it, publish now, save a draft or add it to the queue.

What permissions and data does it ask for?

We did not find a permission list we could verify, so check the install prompt. The Chrome Web Store privacy tab says the developer handles personally identifiable information and website content, does not sell data outside approved uses, and encrypts it in transit (TLS 1.2). Read it before installing.

FAQ

Is the free plan enough? It has tight limits, so it may be mainly a trial; check the vendor's current limits.

Can I save a draft? Yes. You can also schedule, publish now or add to a queue.

Is it good for agencies? The store text mentions team and client accounts.

Good to know

The free plan's post limit is a lifetime cap, not a monthly one. Once it is used, you need a paid plan to keep posting. Check the vendor's current limits, test the composer first, then decide.

Before you install, open the Chrome Web Store listing and read the privacy practices tab and the permissions in the install prompt. Check that the publisher name matches the vendor's own site, and remove the extension if you stop using it, so it no longer has access to your pages. Our how we choose page explains the checks we use, and we do not show ratings or user counts because we cannot verify them.
