Common Questions

How is Zernio different from bundle.social?: └Both are API-first social media platforms, and both ship posting, scheduling, comments, and analytics. The difference is scope and pricing. Zernio also ships DMs, comment-to-DM automation, and ads across 6 networks today, covers WhatsApp/Telegram/Snapchat, and publishes a 99.97% uptime SLA. bundle.social lists its DM and ads APIs as coming soon and prices per organization and usage rather than per account.
Does bundle.social have an ads API?: └Not yet. bundle.social publishes a Social Media Ads API page describing future paid-social workflows, but it’s listed as coming soon. Zernio’s Ads API covers 6 networks and is live today, included at every pricing level.
Which is cheaper, Zernio or bundle.social?: └It depends on your usage. bundle.social starts at $100/month for unlimited accounts but caps posts per plan (10,000/month on Pro). Zernio is free up to 2 accounts, then $6/account (3–10), $3/account (11–100), and $1/account (101–2,000), with unlimited posts.
Does Zernio support WhatsApp and Telegram?: └Yes. Zernio covers 15 platforms including WhatsApp, Telegram, and Snapchat. bundle.social’s platform list (14 platforms) includes Slack and Mastodon but not WhatsApp, Telegram, or Snapchat, so messaging-heavy use cases are a clear fit for Zernio.
Do both work with AI agents?: └Yes. Both offer an official MCP server, a JSON-first CLI, and an OpenAPI spec, so an agent can post through either. Zernio’s MCP server exposes 280+ tools and covers the full loop: publish, analyze, and boost.
