Which one should you pick?
Both are good tools. It comes down to what you post and how you work.
Choose Postbase if
- You post to your own or your team's accounts, not your customers'.
- You want to connect Claude or Cursor by signing in, with no key to paste.
- You want a calendar and composer next to the API, or to self-host.
Choose Ayrshare if
- You're building a product that posts for your users and need white-label, multi-tenant profiles.
- You need networks like Instagram, Pinterest, Reddit, Telegram or WhatsApp today.
- You need a large API surface: comments, analytics and moderation endpoints.
What you get with Postbase
A calendar for every network, an agent built in, and an MCP server for the AI tools you already use.
Connect the AI tool you already use
Claude, Claude Code, Cursor, VS Code, Windsurf or Gemini CLI. Sign in with Postbase and your agent can schedule posts, with no key to paste.

Or use the agent built in
Tell it what to post and when. It checks your channels, writes each version and schedules it when you say so.
Here's a post for all three, with a shorter cut for X. It's set for Wednesday at 12:00.
Everything on one calendar
Posts you write and posts your agent schedules, across every network, in a month, week or day view.

Frequently asked questions
Is Postbase a drop-in replacement for the Ayrshare API?
No. Postbase's API is smaller: list channels, create posts and threads, list and cancel scheduled posts. It's built for posting to your own accounts, not for managing thousands of end-user profiles.
How do AI agents connect?
Add the hosted MCP server to Claude, Claude Code, Cursor, VS Code, Windsurf or Gemini CLI and sign in with Postbase. Or use the @postbasehq/mcp npm package with an API key.
Does Postbase support Mastodon?
Yes, on any instance.
