- Serves cached pages when your origin is down
- HTTPS stays valid — no certificate errors, ever
- Googlebot keeps crawling, so your rankings are safe

How it works
Live in three steps
Add your domain
Create your domain in the panel. nsin scans your current nameservers and imports your existing DNS records automatically.
Point your DNS
Switch to nsin's nameservers and flip records to proxied. Free SSL is issued and renewed automatically — nothing to install.
Tune & watch
Set cache rules, security and rate limits per path, then watch live traffic, cache hit-rate and visitor geography in real time.
Frequently asked questions
What is a CDN and why do I need one?
A Content Delivery Network caches your site at edge locations close to visitors, so pages load faster and your origin handles far less load. nsin adds security and always-on reachability on top.
Do I need to change my code?
No. nsin works at the DNS and network layer. You point your domain at nsin — no SDK, no agent, no code changes.
Is SSL included?
Yes. Free certificates (including wildcards) are issued and renewed automatically and served from the edge — even if your origin is temporarily down. You can also upload your own.
Will a CDN help my SEO?
Yes. Faster load times and reliable uptime are ranking signals, and nsin keeps crawlers like Googlebot connected through outages — protecting indexing and rankings.
How much does it cost?
Every new domain starts on the Free plan, which renews automatically at no cost. Upgrade any time to a per-domain plan with pay-as-you-go bandwidth, where cached traffic is billed at the lowest rate.
Can I stop AI crawlers from training on my site?
Yes. AI Crawl Control lists every AI crawler that reached you, and a one-click policy blocks the training scrapers while leaving Google, Bing and the answer engines that cite you alone. Start in dry run to see what a policy would have done before it does it.
Can I manage nsin from my own code?
Yes. Everything in the panel is a documented REST endpoint, authenticated with scoped API keys. There is also an MCP server, so an AI agent can read your analytics or change a rule directly.
Can I get email at my own domain?
Yes. Email Routing creates addresses like info@your-domain and forwards every message to a mailbox you already use, such as Gmail or Outlook. nsin publishes the MX, SPF and DKIM records for you. It is a forwarder only: nothing is stored, and replies go out from your own mailbox.
Does nsin add security headers and HSTS?
Yes, optionally and per domain. You can switch on no-sniff, a referrer policy, HSTS and removal of fingerprinting headers that reveal your stack, and add any custom request or response header with a header rule. For no-sniff and the referrer policy, a header your origin already sends always wins.
Is nsin only for websites hosted in Iran?
No. nsin routes traffic in both directions: visitors and search engines abroad reach sites hosted in Iran, and visitors in Iran reach sites hosted abroad. Gateways additionally give your servers in Iran a route to global AI, package and cloud APIs.
