postproxy.devAbout Postproxy
Postproxy replaces per-platform social integrations with a single API covering publishing, comments, direct messages, reviews and insights across YouTube, X, TikTok, Threads, Pinterest, LinkedIn, Instagram, Facebook, Telegram, Google Business and Bluesky. You send one payload; the service maps it to each platform's rules and returns a per-platform outcome rather than a single opaque success flag, which is the difference between an integration you can debug and one you cannot. The full engagement flow is exposed, not just publishing — replying to comments, answering DMs and managing reviews all run through the same contract, with webhooks, retries and logs behind it. There are official SDKs for Node, Python and Ruby, verified nodes and apps for n8n, Make and Zapier, and an MCP server so an agent in Claude, Cursor or a similar client can drive it directly. The pricing split is the part that shows who it is actually for: one model billed per connected profile for agents and automations, and a separate one billed per profile group for SaaS products and agencies publishing on behalf of clients, with each group covering up to eleven connected platforms. The documentation and integration pages are published per platform rather than as one combined reference, so the specific constraints of each network are visible before you write against them, and Bluesky is listed as coming soon.
