For developers

Keep your stack. Put fast.site in front.

You connect your domain through its nameservers. Hosting, code and deployments stay as they are. You control caching with standard HTTP headers and check every step with tools you already know.

# Does the domain point to fast.site?
$ dig NS example.com +short

# Request twice: first MISS, then HIT
$ curl -sI https://example.com | grep -i fs-cache
fs-cache: MISS
$ curl -sI https://example.com | grep -i fs-cache
fs-cache: HIT
A MISS on the first request is normal. After that, the response comes from the edge.

Caching

You control the cache with headers

fast.site respects the Cache-Control headers your origin sends. Without them, a template for your platform applies, which already leaves admin, cart, checkout and login uncached.

Purge when something changes

Clear the cache for a list of URLs or the whole domain, optionally as a soft purge. The purge log shows your recent purges.

URLs with different query strings are cached separately, for example ?v=1 and ?v=2.

Cache settings in detail
  • Cache pages for one hourCache-Control: public, max-age=3600
  • Cache versioned files like app.v2.js for a yearCache-Control: public, max-age=31536000, immutable
  • Never cache personal responsesCache-Control: private, no-store

In the dashboard

Everything else is set per domain

Every setting applies to one domain, so you can try changes on a test domain before they go live.

  • DNS and SSL

    Manage DNS records and choose proxied or DNS only for each one. SSL runs automatically or with your own certificate.

    In the docs

  • Firewall and protection

    Firewall rules with expressions, countries and actions such as block or challenge. Plus a WAF in monitor or block mode, rate limiting and HSTS.

    In the docs

  • Analytics and logs

    Traffic, cache status, top paths and the slowest origin responses for each domain. A log shows what the firewall allowed or blocked.

    In the docs

  • Images and HTML

    Growth and Scale serve images as WebP automatically. Brotli compression is automatic, and you can switch on HTML optimization when you need it.

    In the docs

  • Speed previews

    Before you switch, a preview measures the same URL once from your origin and once through fast.site.

    In the docs

  • Regions

    Choose which regions serve each domain. Additional regions are available as add-ons.

API

API keys for your own automation

Create API keys in your account and send them as a bearer token. A key carries your account's full permissions, so it belongs on your server and never in frontend code. We'll work out with you which endpoints your use case needs.
