As answered by people managing Insomnia REST and Postproxy.
Postproxy's answer:
We were building a product for ads creation at scale with fancy templates management, different platforms with adaptive sizing. Then Nano Banana got released and made a product largely obsolete. Postproxy was basically a part of that product.
Postproxy's answer:
Postproxy is a production-grade social media API for SaaS products, AI agents, and multi-tenant platforms. It provides one API for publishing, comments, direct messages, reviews, analytics, webhooks, and OAuth account connections across Instagram, Facebook, Threads, LinkedIn, TikTok, X, YouTube, Pinterest, Google Business Profile, Bluesky, and Telegram.
Compared with publishing-only APIs and automation tools, Postproxy is designed for customer-facing products that require official platform integrations, explicit delivery statuses, automatic retries, profile-group isolation, predictable pricing, and infrastructure built for production workloads.
Postproxy's answer:
Postproxy combines production-grade publishing infrastructure, engagement, and analytics in one social media API. Every publishing request has an explicit status and human-readable failure reason, failed deliveries can be retried automatically, and the same platform also handles comments, direct messages, reviews, profile analytics, and webhooks.
Postproxy uses official platform APIs and OAuth flows, supports isolated profile groups for multi-tenant products, and provides integrations for n8n, Make, and Zapier, as well as an MCP server for AI agents.
Postproxy's answer:
Postproxy is primarily built for developers and product teams creating SaaS platforms, AI agents, marketing tools, and multi-tenant social media products. It is also used by agencies and automation specialists that manage social accounts for multiple customers.
Individual creators can use Postproxy, but the platform is optimized for software products and production workflows rather than manual social media management.
