Postproxy

What it does

Postproxy is a unified publishing API for social networks. It provides a single REST API endpoint to publish content, manage comments, respond to DMs, and retrieve analytics across multiple platforms including Instagram, Facebook, Threads, TikTok, X (Twitter), YouTube, LinkedIn, Pinterest, Bluesky, Telegram, and Google Business Profile. The API handles per-platform content mapping, retries, scheduling, and returns per-platform outcomes. It also offers official SDKs for Node, Python, Ruby, and other languages, as well as integrations with n8n, Make, and Zapier. Postproxy supports agentic workflows via MCP server, skills, and OpenClaw for Claude and Cursor.

Who it is for

Postproxy is built for developers and teams who need to automate social media content at scale. It targets three main segments:

• SaaS companies that want to embed social features into their product without building per-platform integrations. Postproxy allows provisioning scoped environments per customer so users connect through the SaaS UI.
• Automation and AI builders who need a reliable social step in pipelines. Postproxy provides skills for Claude Code, an n8n node, and raw API for publishing, replies, and engagement.
• Agencies managing multiple clients. Postproxy offers smart queues, scheduling, and profile groups to keep clients' posts, comments, and DMs separate.

Why it matters

Managing social media across multiple platforms typically requires integrating with each platform's API individually, which is time-consuming and error-prone. Postproxy reduces this to a single integration, saving weeks of development time. It handles platform-specific rules, retries, and error handling, providing a consistent interface. The API also supports full engagement (comments, DMs) and analytics, making it a comprehensive solution for social media automation. Postproxy runs on EU infrastructure, is GDPR-compliant, and is pursuing SOC 2 Type II certification, addressing data sovereignty and security concerns.

Launch signal

Postproxy is live and operational, with a free plan available. The website showcases testimonials from customers like Vendedor Global, Rabe Marketing, Needle, and Renkka.ai, indicating real-world usage. The product has processed millions of API requests with average response times around 140ms (p95 under 300ms). It has verified integrations with n8n, Make, and Zapier, and supports agentic workflows. The founder is Dmitry Sereda.

Brand and naming

The name 'Postproxy' is functional and descriptive, combining 'post' (social media content) with 'proxy' (intermediary), clearly hinting at its role as a unified API layer. However, it lacks distinctiveness and emotional appeal, blending into the crowded 'proxy' naming space. The domain postproxy.dev is available and memorable, though the .dev TLD may limit mainstream recall. Positioning is clear: one API for multi-platform social media management, but the name doesn't inherently convey the full scope (comments, DMs, analytics).
