About Postproxy
What if publishing to social media could be as reliable and predictable as sending an email? Postproxy is an exploration into turning that idea into reality. It's a unified API layer designed to transform the chaotic, fragmented process of multi-platform social media publishing into a stable piece of infrastructure. At its core, Postproxy acts as a single, intelligent endpoint that sits between your application and the ever-shifting APIs of platforms like Instagram, Facebook, YouTube, LinkedIn, and X. It's built for developers, automators, and teams who are tired of the hidden complexities—the platform bureaucracy, inconsistent rules, account sprawl, and operational failures that only reveal themselves at the worst possible moment. By abstracting away the need for platform-specific integrations, OAuth flows, rate limit handling, and content adaptation, Postproxy offers a consistent and reliable publishing contract. This allows you to focus on creating and routing content, whether it's generated by LLMs, triggered by CI/CD pipelines, or orchestrated in tools like n8n and Zapier, with the confidence that the "last mile" of delivery is handled with deterministic logic and clear reporting.
