Analysis

An editorial look at what each product does well and who it suits.

Postproxy
Speed-Check

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

Overall verdict

  • Speed-Check.net is a simple, no-frills internet speed testing tool that provides quick and accessible measurements of download, upload, and ping speeds without requiring installation or account creation.

Why this product is good

  • Free and easy to use with no signup required
  • Provides quick results for download, upload, and ping speeds
  • Accessible directly from a web browser on multiple devices
  • Lightweight interface that doesn't require heavy bandwidth to run the test itself
  • Useful for basic troubleshooting of internet connectivity issues

Recommended for

  • Casual users wanting a quick check of their internet speed
  • People troubleshooting basic connectivity issues at home
  • Users who prefer a simple, ad-light testing experience
  • Those who don't need advanced diagnostics or detailed historical data tracking

Questions & Answers

As answered by people managing Postproxy and Speed-Check.

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.

Speed-Check's answer:

Speed-Check was launched in August 2025 as an independent alternative to the ad-heavy, account-gated speed tests that dominate the market. The goal was simple: build a speed test that respects user privacy, uses open measurement protocols (M-Lab NDT7), and gives back to the web by offering a free embeddable widget and browser extensions — without ever asking for a signup.

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.

Speed-Check's answer:

Because it combines accuracy with transparency: M-Lab NDT7 results within 2–5% of Ookla, but without the heavy ads, tracking, video pre-rolls, or mandatory accounts. The embeddable widget is free in three sizes (Ookla charges $300+/month for Speedtest Custom), upload/ping/jitter are shown by default (unlike Fast.com, which hides them), and the entire methodology is open and verifiable. Ideal for users, webmasters, and ISPs who value privacy, fairness, and full metrics.

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.

Speed-Check's answer:

Speed-Check is an open-source, privacy-first internet speed test built on the M-Lab NDT7 protocol (the same standard Google uses) combined with Cloudflare endpoints. Unlike most competitors, it requires no account, stores no personal data on public pages, runs only a single light ad placement, and offers a completely free embeddable widget — features that are paywalled or hidden elsewhere. It also ships with dedicated Chrome and Firefox extensions, a PWA install option, and detailed country-level rankings, glossaries, and guides.

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.

Speed-Check's answer:

Privacy-conscious internet users, remote workers, gamers, and streamers who want a fast, accurate, no-nonsense speed test — plus webmasters, bloggers, and ISPs looking for a free, embeddable widget. Secondary audiences include journalists and researchers who use the global country rankings and the open M-Lab methodology for citations.

Which are the primary technologies used for building your product?

Speed-Check's answer:

React 18, Vite 5, TypeScript 5, Tailwind CSS, M-Lab NDT7 (measurement protocol), Cloudflare (CDN and edge measurement endpoints), Supabase (backend/edge functions), and PWA standards. Browser extensions are built on Manifest V3 (Chrome) and the WebExtensions API (Firefox 140+).

Who are some of the biggest customers of your product?

Speed-Check's answer:

As a privacy first speed test this is unknown to us. None of our users are being tracked by size and they don't need to sign up on our website.
