Questions people ask

Which posting APIs are compared here?

Ayrshare, Upload-Post, Zernio, bundle.social, Post Bridge, Postiz, Blotato — every pair of them, each with PostWire next to it. Every competitor fact links the vendor page it was read from, with the date.

Why is PostWire on every page?

Because it is a third option for anyone choosing between two posting APIs: priced per business, a free plan with the API and MCP, and it writes each network's post from one idea. As of Sept 2026, we couldn't find another hosted API that writes a different native post per network from one prompt, in one call.

Type one idea and see the post each network gets.

The demo on the home page writes live, with no account, and never publishes. The free plan covers one business — every network connects free, 2 networks per post — with no card and no time limit. Paid plans have a 14-day refund.
