Buffer vs Typefully vs Postiz vs Postwire
Postwire is a social media auto poster built for AI agents that is compared here against three popular tools on who operates it, where it posts and where it runs.
Who operates it
Buffer and Postiz are built for people scheduling in an app, with calendars and team features. Typefully is built for people writing threads and short posts. Postwire is built for a program: an AI agent sends a package and approves variants over plain-text endpoints.
Where it posts
Buffer, Typefully and Postiz publish through official platform integrations, each with its own list. Postwire uses no platform APIs for posting: a local Chrome extension fills X, Threads, Instagram, Facebook, Dev.to, Medium, Reddit, LinkedIn and Xiaohongshu in their own web editors, and a human clicks publish on every post.
Where it runs
Buffer and Typefully are hosted services. Postiz can be hosted or self-hosted with Docker. Postwire runs as a Cloudflare Worker plus an extension on your Mac, and your platform logins stay in your own Chrome profile.
Which to pick
Hand-scheduling with analytics: Buffer. Writing threads: Typefully. Self-hosted, open source: Postiz. An agent that already writes and needs to reach no-API platforms too: Postwire. For prices, use each vendor's own pricing page.
