Your website's emergency failover plan

How Siteavail Works

Three steps. No agents, no plugins, no code changes.

1

Add your domain and we back it up automatically

Enter your domain and we visit it with a real browser to save a complete, browsable backup. Runs daily, weekly, or monthly on your schedule.

2

Preview every backup and validate failover anytime

Every backup is stored on infrastructure independent from your web host. Open any version whenever you want, and preview the live failover copy before an outage ever happens.

3

Switch your domain in minutes when your host has a problem

Update your DNS to point at Siteavail and your most recent backup goes live on your own domain with automatic SSL. Switch back when your primary host recovers.

Everything you need for a reliable backup plan

Simple tools for serious website continuity.

Real Browser Backups

Unlike simple crawlers, we capture your site exactly as visitors see it, including client-side JavaScript and modern front-end rendering. Your backup is a fully browsable copy, not just a screenshot or HTML export.

Preview Every Backup

Browse any backup of your site and preview the failover copy before you need it. Validate readiness yourself instead of trusting a black box you only test during a disaster.

Time Travel

Open any previous version of your site whenever you need to. See what your site looked like last week, last month, or six months ago. Every backup is dated and browsable.

Your Domain During Failover

Visitors stay on your domain, not ours. SSL is provisioned automatically, and failover works on your root domain, www, or supported subdomains.

Independent Infrastructure

Your backups and failover environment live on completely different providers and networks than your web host. When they have an issue, Siteavail stays out of the blast radius.

Battle-Tested Archive Technology

Archives are indexed using the same open-source technology that powers the Internet Archive's Wayback Machine, with fast and accurate lookups across thousands of pages.

When your host has a problem, your site doesn't

Built for businesses that can't afford to go offline.

Your store goes offline during a sale

Customers still see your products, pricing, and contact info instead of an error page. You stop the bleeding while your team fixes the hosting issue.

A client's migration goes wrong on Friday evening

Switch to a failover copy you've already previewed and know is good. No scrambling, no apology email, no blank page all weekend. Monday morning, you're the hero.

A client asks what your site said six months ago

Browse any previous version from your archive on demand. Every backup is dated and browsable, ready for compliance reviews, legal holds, or just checking what changed.

Less than one hour of downtime costs most businesses.

Frequently Asked Questions

Everything you need to know about Siteavail.

Any publicly accessible website: WordPress, Shopify, custom-built sites, static sites, marketing pages, company sites, newsrooms, public subdomains, and more. As long as visitors can view it in a browser, we can back it up.

Yes. Every customer can view their backups and preview the failover copy before they need it. That makes Siteavail easier to validate than a disaster-recovery product you only discover during an emergency.

Your backup is served within seconds on our end. The main variable is DNS propagation after you switch your records. We provide guidance on optimizing your DNS settings for the fastest possible switchover.

HTML, CSS, images, and client-side JavaScript are preserved exactly as visitors normally see them. Dynamic server-side features such as shopping carts, login forms, and real-time search won't function during failover. It's designed for emergency use while you resolve your hosting issue, not as a permanent replacement.

Not for backups. Those run automatically after you add the site in your dashboard. You only update DNS when you want to activate failover, and we provide the exact records and step-by-step instructions.

Point your DNS back to your host. There's no lock-in and nothing to uninstall. Your backups remain available for future validation and future incidents.

Your backups are stored on enterprise-grade, S3-compatible object storage on infrastructure that's completely independent from your web host. Different providers, different networks, encrypted in transit.

Your live site is unaffected unless you explicitly activate failover by changing DNS. Our failover infrastructure is separate from your host, and Siteavail only serves traffic when you choose to use it.
