Overall verdict

  • I don't have reliable information about Postproxy (postproxy.dev) in my knowledge base, so I can't give you a verified assessment of whether it's good. I'd recommend evaluating it directly against your own requirements before committing.

Why this product is good

  • The service appears to be a proxy-related developer tool based on its name and domain, which could be useful for API request handling, testing, or routing
  • A dedicated '.dev' domain suggests it targets developers, which often means a focus on developer experience and integration
  • Proxy tools in general can help with tasks like request inspection, mocking, rate limiting, and debugging
  • Without verified reviews or documentation, you should check its official docs, pricing, uptime/SLA claims, and community feedback before relying on it

Recommended for

  • Developers who need a quick proxy or request-routing solution and are willing to trial the tool first
  • Teams evaluating lightweight API proxying, mocking, or debugging tools
  • Users who prioritize doing their own due diligence via official documentation and independent reviews before adopting a service

Questions & Answers

As answered by people managing Link Whisper and Postproxy.

What's the story behind your product?

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.

Why should a person choose your product over its competitors?

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.

What makes your product unique?

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.

How would you describe the primary audience of your product?

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.
