Where PostWire is ahead
- The lowest bill of the three for an agency. 10 clients on 5 networks: $29 a month on PostWire Pro, every network included. Ayrshare: $299; Post Bridge: $99.
- It writes the posts. One request turns one idea into a native post per network — a hook for TikTok, a title and tags for YouTube, a longer post for LinkedIn — and the next call publishes them. Ayrshare publishes the text you send; its AI features come with the Max Pack, a +$300 a month add-on on Business.
- A free plan, not only a trial. 1 business, 20 posts a month, with the REST API and the MCP server, no card and no time limit. Post Bridge has a 7-day trial, and free users get 5 posts.
- A free plan, with the API and MCP in it. 1 business, no card, no time limit. Ayrshare has no free plan; its 28-day trial is on Launch only.
- Every network's post written for you, from one idea, in one request — a hook-first caption for TikTok, a searchable title and tags for YouTube, a longer first-person post for LinkedIn. On Post Bridge you write once and customize each platform yourself.
- Add it to Claude by signing in. PostWire's hosted MCP server takes OAuth 2.1 or an API key. Ayrshare's MCP server authenticates with a static Bearer key, so it is not a connector you add by signing in.
- Approvals from $9 a month. On every paid plan a post can wait until a person approves each network's version, and Pro includes 25 seats with roles. Post Bridge adds team members on Operator, $99.
