What is Buffer?
Buffer is a simple, popular social media scheduler for planning and publishing posts across up to 11 networks including Facebook, Instagram, TikTok, LinkedIn, X, YouTube, Threads, Pinterest and Bluesky. It offers a clean queue and calendar, an AI Assistant for drafting, own-account analytics, a reply inbox, a link-in-bio page and team approvals. Its permanent free plan (3 channels, 10 posts each) makes it a favourite for solo creators. It is built to publish your content — not to discover viral posts across networks.
- Very affordable, with a genuinely usable permanent free plan
- Broad publishing coverage — 11 networks including Threads and Bluesky
- Clean, beginner-friendly scheduling with an AI Assistant
- Per-channel pricing adds up for many accounts
- No viral/trend discovery — you source content yourself
- No social listening; deeper features gated to the Team plan
Pricing: from ~$5/mo per channel (free plan)
What is Semrush?
Semrush is an all-in-one SEO and digital-marketing suite: keyword research, competitor analysis, rank tracking, site audits, plus content and (via add-ons) social tools. It is a powerhouse for search marketing and is sometimes compared to BuzzSumo for topic research. But its core is SEO and paid search, not discovering the viral posts trending across social networks, and the social features are add-ons rather than a real-time cross-network radar.
- Enormous keyword and competitor database
- Full SEO + content + PPC toolkit
- Topic research and content templates
- SEO-centric — social viral discovery is an add-on
- No editorial board or team workflow for content
- Add-ons push the price up fast
Pricing: from ~$139/mo
What is ViralHunt?
ViralHunt is a viral-content discovery platform that tracks the top-performing posts across 12 networks — TikTok, Instagram, Facebook, Pinterest, Reddit, X, Bluesky, Mastodon, Douyin, RSS, Quora and Tumblr — in real time. Beyond discovery, it turns trends into a team workflow with an editorial Kanban board, an AI content studio and built-in team chat — and now schedules and auto-publishes finished posts to 11 social networks, with separate brand/client projects. So a whole team can find, create and publish content in one place instead of stacking a discovery tool, a workflow tool and a scheduler.
- Tracks viral posts across 12 networks in one dashboard
- Editorial board, AI studio and team chat built in — no extra tools
- Schedules & auto-publishes to 11 networks, with multi-brand projects
- Affordable, a free plan that never expires, plus a REST API for AI agents
- Not a dedicated enterprise listening/analytics suite
- Younger brand than the incumbents
Pricing: from $29/mo
