What Postproxy is
Postproxy is a unified social media API built for developers. Instead of integrating with each platform on its own, you use one API to post content, reply to comments, handle direct messages, and read analytics across networks such as Instagram, TikTok, LinkedIn, X, YouTube, Facebook, Threads, and Bluesky. It exposes REST endpoints, webhooks, retry logic, logs, and per-platform result feedback, and it ships official SDKs for Node, Python, and Ruby. The service also adapts to each platform's rules and limits so your content posts and displays the way it should. A free trial is available and does not require a credit card.
What you can do with it
- Post content to many platforms from a single request
- Reply to comments and manage direct messages in one place
- Pull per-platform analytics to see how content performs
- Automate posting and replies through Zapier, Make, or n8n
Who it is for
- Developers adding social posting to their own product
- Social media agencies that run several client accounts
- Automation builders who need posting and replies in a workflow
- SaaS products that want to offer social management to users
What to watch out for
The page offers a free trial but does not list paid pricing, so costs may change and you should check the site for current plans. You still need to write and maintain code against the API, so it is not a no-code tool. Because it wraps third-party platforms, any change to their API rules or rate limits can affect what you can do, and that is outside Postproxy's control. Some platforms may also require their own approval or access before the API can post to them. Test each platform's behavior before you rely on it in production.
