Rheos vs Buffer: Honest Comparison for Small Businesses
Both do scheduling. Only one writes the content for you on brand. Here is how they compare across pricing, AI, platforms, and who each is actually for.
TL;DR
- Buffer is the OG scheduling tool. Good at queuing posts you already wrote. Limited AI.
- Rheos is an AI-first content platform that reads your website, learns your brand, and creates on-brand content before scheduling it.
- Pick Buffer if you already write every post and want a clean queue.
- Pick Rheos if you want the AI to handle content creation for you — text, images, and carousels.

Where Buffer wins
- Platform breadth. Buffer supports Mastodon, Pinterest, Threads, Google Business Profile out of the box.
- Maturity. Around since 2010. Extremely stable. Mobile app is polished.
- Price per channel at the low end. If you only need 1-2 channels and a simple queue, Buffer Essentials at £5/channel is cheaper than Rheos Business.
- Pure scheduling UX. Buffer does one job very well. No learning curve.
Where Rheos wins
- Content creation is built in. Rheos generates the post — text, image, or carousel — using AI trained on your brand. Buffer expects you to write and design yourself.
- Brand-aware AI. Rheos reads your website, learns your voice, colours, and audience. Buffer's AI is generic.
- Better free tier for SMEs. Rheos Free includes image generation; Buffer Free has no AI and no images.
- UK-based, GBP-priced. No FX fees for UK businesses. Built for the UK SME market.
- More in one subscription. Rheos Business (£35) includes AI content + scheduling + analytics. Buffer equivalent needs Buffer + Canva + Buffer Analyze add-on, which adds up.
Who should pick Buffer
Pick Buffer if:
- You already write every post yourself and have the time to do so.
- You just need a reliable queue.
- You post to Mastodon, Pinterest, or Google Business Profile heavily (Rheos doesn't cover these yet).
- You are comfortable designing your own images in Canva.
Who should pick Rheos
Pick Rheos if:
- You want content created for you on brand, not just queued.
- You do not have a content strategist or designer.
- You value UK-based pricing and support.
- You want AI that learns your brand, not a generic ChatGPT wrapper.
