The Fatal Flaw: API Requires $21+/mo Business Plan

Switching from Publer?
Zernio's API is simpler and more accessible than Publer's. No Business plan required - sign up, copy your API key, and start posting. Most developers are live in under 15 minutes.
Zernio is $168/mo at 50 accounts (usage-based). Publer's per-account add-on rate isn't published in a flat table, so exact savings depend on the negotiated rate, but the gap widens past 100 accounts where Zernio drops to $1/account.
