Unified social media API for agencies, SaaS products and AI agents to publish, reply and engage across platforms.

Postproxy homepage screenshot, productivity & writing AI tool

Our take: Postproxy suits SaaS builders, agencies and automation or AI-agent developers who want one API to publish and engage across social platforms without handling each platform's app reviews.

Main limitation: Billing is per connected profile or profile group, and platform rate limits such as X at 20 posts per 24 hours still apply.

By the AI Tool Atlas editors. Based on the vendor's official documentation; we have not tested this product hands-on. What “documented overview” means

Is Postproxy right for you?

Postproxy suits SaaS builders, agencies and automation or AI-agent developers who want one API to publish and engage across social platforms without handling each platform's app reviews. Based on the vendor's documentation, not on a hands-on test.

Best for: SaaS builders

Also a good fit for

  • Agencies
  • Automation builders

Consider another tool if pricing billed per connected profile or group

Or if

  • Platform rate limits still apply (X capped at 20 posts/24h)
  • Developer-oriented
