Why IPStar

Built for the use case giants ignore

We don't sell proxies. We just tell you if they're any good.

Privacy by default

Keys live in Cloudflare Workers — never exposed to the browser. Results cached in KV for 12–24h to reduce external calls.

Small seller friendly

Built for indie shops, dropshippers and solo devs. No "schedule a demo" popups, no "enterprise plan".

Technical & honest

Plain numbers, clear sources, real cache timestamps. No fluffy marketing scorecards.

Mobile first, fast

Static pages on Cloudflare Pages. Fonts preloaded, images in WebP. Target LCP under 2.5s.

Proxy Guides

Sorted by what you're actually trying to do — not by who pays the highest affiliate fee.
