November 2026 comparison

Buffer vs Supergrow A free scheduler, or posts from an AI interview.

Both connect to LinkedIn through its official sign-in, and neither wrote a post from my one-line idea. Buffer is a scheduler for 12 networks, free for 3 channels, with good stats and a comments inbox. Supergrow is LinkedIn only and writes from an AI interview called PostCast, with a first comment, a Kanban board and team approvals, at $39 a month with a 7-day trial that asks for a card. I tried Supergrow on 7 November and Buffer on 10 November 2026.

5 differences that matter.

  1. 1

    Where the post comes from

    Buffer

    From you. The AI Assistant expands, rephrases and shortens your text. Asked for a full post from my idea, it asked me to share the idea.

    Supergrow

    Mostly from PostCast, an AI interview on one topic (10 to 15 minutes on its site, 30 in the app), plus repurposing from videos, articles and PDFs. My one-line idea got “Failed to rewrite”.

  2. 2

    Price and trial

    Buffer

    Free for 3 channels. Essentials is $6 a channel a month ($5 yearly), and a profile and page count as two. The free plan asked me for no card.

    Supergrow

    $39 a month for one LinkedIn account ($31 yearly), $199 for Teams of 5. The 7-day trial asks for a card during sign-up. Refunds only for billing errors.

  3. 3

    Planning your posts

    Buffer

    An Ideas board, a queue and a calendar, with recommended times from a weekly posting goal.

    Supergrow

    A Kanban board from draft to published, a calendar, and a Viral Posts search for ideas.

  4. 4

    Stats and comments

    Buffer

    LinkedIn stats from the day you connect, even on Free, and an inbox of unanswered comments with suggested replies.

    Supergrow

    Profile and post stats with a weekly report, and Engage for comments.

  5. 5

    Networks and teams

    Buffer

    12 networks. The Team plan adds unlimited users and approvals, priced per channel.

    Supergrow

    LinkedIn only. Teams adds approvals, an organisation dashboard and per-member voice profiles, for 5 accounts.

First-hand

Same idea, no post from either.

Kaustubh KatdareFounder, Wiral.Social

Supergrow asked for my card before I could write a word. Then my one-line idea got “Failed to rewrite”, and its posts came from a 30-minute AI interview instead. They were inspired by what I said, but partly made up. I cancelled the same day.

Buffer asked for no card. But when I asked its AI to write a full post from my idea, it asked me to share the idea, which was already in the post. It still wants me to do all the thinking and hard work.

Both do some things well. Supergrow’s Kanban board and Viral Posts are genuinely good. Buffer’s Insights showed my last 30 days the moment I connected, and its comments inbox is very useful.

So pick by what you need. Free scheduling and good stats: Buffer. Interviews, a first comment and team approvals: Supergrow. Posts in your own voice from a single line is why I built Wiral.

What reviewers say.

What people say about Buffer

4.3 on G2 (1041 reviews)4.5 on Capterra (1492 reviews)4.2 on Trustpilot (143 reviews)4.3 on Chrome Web Store (3000 reviews)

“Buffer remains one of the most accessible social media management tools on the market”

Rated 4 out of 5: one of the easiest social tools to use, priced per channel so small teams pay little, though not the most feature-packed.TechRadar (Rob Clymo)

“Buffer's real standout feature is its value for money.”

Picked as the best app for plain social media scheduling, mainly for value for money; the free plan covers about a week of posts for a small business.Zapier (Andrew Kunesh, Tim Brookes)
  • Users praise how easy and intuitive scheduling is; a common wish is for more complete analytics
  • Most negative Capterra reviews are about bugs: posts not going out and channels needing to be reconnected
  • Teams say shared access makes onboarding and working together easy
  • One reviewer reports posts failing to publish every week; another wants an exact per-network preview before posting; another says cost climbs with each added platform

What people say about Supergrow

  • A G2 reviewer (4/5, Mar 2026) likes scheduling with the calendar view, the simple setup and responsive support
  • The same G2 reviewer says analytics have not worked well and wants better views of performance over time and top posts
  • Earlier G2 reviewers (5/5, Nov 2023) call it a simple, powerful tool for growing a personal brand on LinkedIn
  • The only Product Hunt review, from a SaaS founder, says it made creating and scheduling LinkedIn posts much faster
