The AI-first alternative to Buffer.
Rheos does everything Buffer does — plus it reads your website, learns your brand, and writes the posts for you.
TL;DR
- Buffer is a scheduling tool. You bring the content.
- Rheos is a content platform with AI that learns your brand and creates posts on-brand, then schedules them.
- Rheos Free beats Buffer Free for anyone who uses AI.
- Buffer still wins on platform breadth (Pinterest, Mastodon, Google Business Profile).
Why small businesses are switching from Buffer
AI that knows your brand
Rheos reads your website and learns your tone, colours, and audience. Buffer's AI Assistant is a generic LLM that doesn't know your brand.
Image and carousel generation built in
Rheos creates images and carousels on-brand (AI video coming). With Buffer you still need Canva, a designer, or stock photos.
Better free tier for SMEs
400 AI credits, LinkedIn + X + Threads publishing, no credit card. Buffer Free has a 10-post cap per channel and text-only AI that isn't brand-aware.
UK-priced, UK-supported
GBP pricing, UK GDPR compliance, UK-based support. No FX fees or time-zone gaps.
Platform coverage at a glance
Rheos publishes to all 10 platforms on every plan. Here's what Buffer covers — and what it doesn't.

Plus: only Rheos has this
The first MCP server for social media.
Rheos ships with an MCP (Model Context Protocol) server plus a full REST API. Draft posts directly from Claude, ChatGPT, Gemini, or Cursor — the AI reads your brand context, formulas, and scheduled calendar, then writes and queues the post in Rheos. Buffer doesn't offer this.
Available on Business and Team plans. Free to set up. Works with any MCP-compatible AI client.

Pick Rheos if…
- You want content created for you on brand, not just queued.
- You don't have a designer or content strategist.
- You post to 3+ platforms (Rheos is cheaper than Buffer's per-channel model).
- You value UK pricing and compliance.
Stick with Buffer if…
- You already write every post and just need a queue.
- You post heavily to Mastodon, Pinterest, or Google Business Profile.
- You only use 1-2 channels (Buffer Essentials at £5/channel is cheapest).
Frequently asked questions
Is Rheos cheaper than Buffer?
For most SMEs on 3+ channels, yes. Rheos Business is £35 flat for all platforms + AI content. Buffer Essentials is from $5/channel/month (annual) with text-only AI, so 4 channels is ~$20/mo — and you still need a separate image tool like Canva. Rheos is usually cheaper once you factor in what you'd otherwise pay for content tooling.
Does Buffer have AI content generation?
Buffer has an AI Assistant that generates captions and post ideas from a prompt. It's text-only — no image or video generation — and doesn't learn your brand voice from your website. Rheos reads your website to learn your brand, then generates text, images, and carousels (video coming soon) on-brand.
Which is better for Instagram?
Both auto-publish to Feed and Reels. Buffer has longer-established Instagram support. Rheos generates the visual content before scheduling — images and carousels (video coming) — so Rheos is better if you need content creation, Buffer if you already have the content and just need a queue.
Can I migrate from Buffer to Rheos?
Yes. Rheos imports your connected accounts via OAuth. Scheduled posts in Buffer's queue don't auto-migrate — you'd re-create them in Rheos, which typically takes 10-20 minutes for a month of content since Rheos generates most of it for you.
Does Rheos have a Buffer-style queue?
Yes. Every post has a calendar view where you schedule, reschedule, or queue. Rheos auto-suggests the best time per platform based on your audience.
