Where they pull apart

Postiz

Stands out: Agent access is the product, not an add-on. Every plan includes a hosted MCP server with OAuth sign-in, a CLI skill and a public API, so a recruiter can ask Claude to turn one job post into LinkedIn, X and Facebook versions and schedule them for the week. The AGPL-3.0 code on GitHub has over 37,000 stars.

Watch out: There is no permanent free plan on the cloud version, and the $29 Standard plan is solo only with no AI images. Self-hosting is free but means running Docker yourself and getting your own developer app approved by Meta, TikTok and YouTube, which can take weeks. It is a general social tool, so it has no job posting, ATS or candidate features.

Not the right fit for

  • Recruiters who only need LinkedIn and want writing help (a LinkedIn-first tool fits better)
  • Buyers who want a permanent free plan
  • Teams that need job distribution to job boards or ATS integration

SocialBu

Stands out: Covers 12 networks, including Threads, Bluesky, Mastodon and Google Business Profile, with a free entry plan.

Watch out: Free is 3 accounts and 10 lifetime posts. Starter caps at 8 accounts and 750 posts a month; automation and social listening sit on higher plans.

Not the right fit for

  • Anyone who needs more than 10 free posts
  • Teams that need social listening on the entry plan
