💸 Better value
One affordable plan instead of stacking a discovery tool + a workflow tool + a listening tool.
What is Exploding Topics?
Exploding Topics uses machine learning to surface emerging trends, products and markets months before they peak. It is a trend-spotting database with a weekly newsletter and a Trends API, ideal for early market research. The catch: it shows topic-level trends, not the actual viral posts on each social network, and has no engagement tracking or team tools.
- Genuinely early trend detection (12-month forecasts)
- Affordable entry plan
- Trends API for automation
- Topic-level only, not per-network viral posts
- No engagement tracking or team workflow
- API is a costly add-on
Pricing: from ~$39/mo
What is Postiz?
Postiz is an open-source "agentic social media scheduler": cloud plans from $29 a month (Standard, 5 channels) to $99 (Ultimate, 100 channels), or self-hosted on your own server at no licence cost. Every plan includes the hosted MCP server, the Postiz CLI, the public API and webhooks, so Claude, ChatGPT, Codex, Cursor or Gemini can schedule through it. It publishes to X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Threads, Pinterest, Reddit, Discord, Bluesky, Mastodon and more. Like Blotato, it is the last mile only: it does not find the content.
- Open source and self-hostable
- MCP server, CLI, API and webhooks on every plan
- Wide network list including Reddit, Discord, Bluesky and Mastodon
- No trend or viral discovery
- No drafts, review or approval gate for what an agent sends
- Channel caps per plan (5 on Standard)
Pricing: from $29/mo for 5 channels (7-day trial); self-hosting free
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
