A full clone.
In five minutes.

StageForge creates a pixel-perfect replica of your live WordPress site inside a sandboxed Docker container — posts, plugins, users, options, uploads, the lot. Connected via OAuth. Running in your chosen region. Ready for chaos.

✓ OAuth · no SFTP ✓ 3-region provisioning ✓ Live in 2–5 min

01 · Scope of clone

Everything the live site sees.
Nothing it can touch.

The clone is a byte-faithful copy — down to serialized option values and cron schedules — but all outbound writes are intercepted at the container boundary.

Cloned 1:1
✓ BYTE-EXACT
DATABASE
All wp_* tables + custom tables
UPLOADS
wp-content/uploads (any size)
PLUGINS
Active + inactive, with state
THEMES
All themes + child customizations
OPTIONS & TRANSIENTS
Serialized, rebuilt on import
MU-PLUGINS
Drop-ins, object-cache, advanced-cache

Each outbound call is logged. Allow-list a specific host to let it through.
02 · Connection

OAuth in 90 seconds.
Never an FTP password.

Install the WordPress plugin (or drop a one-line PHP mu-plugin). It exposes a single REST endpoint. You authorize once from the StageForge dashboard — handshake is signed with HMAC-SHA256, rotated every 15 minutes.

▸ Zero inbound firewall changes
▸ No wp-config.php edits required
▸ Revoke access at any time from /wp-admin
▸ Works behind Cloudflare, Sucuri, WAF

03 · Timing

Median boot: 2m 48s.
P99: 4m 12s.

We keep a warm pool of pre-provisioned containers in each region. The bulk of your time is spent encrypting the backup (at the CPU of your live host) and running wp search-replace against serialized data.

▸ 50 GB site · median 6m 40s
▸ Warm pool eliminates cold-start latency
▸ Parallel table import for DBs over 2 GB
04 · URL rewriting

Serialized data, handled.

Most staging tools break when plugins store serialized PHP arrays with absolute URLs. We walk every row and rewrite in-place without breaking object length prefixes.

Before · live site
a:3:{
  s:4:"url";
  s:24:"https://acme-shop.com";
  s:4:"api";
  s:34:"https://api.acme-shop.com/v2";
  s:5:"email";
  s:17:"orders@acme-shop.com";
}

After · staging
a:3:{
  s:4:"url";
  s:42:"https://a1b2c3.staging.stageforge.app";
  s:4:"api";
  s:52:"https://api-a1b2c3.staging.stageforge.app/v2";
  s:5:"email";
  s:25:"orders@staging.acme-shop.com";
}
Object length prefixes (s:24 → s:42) rewritten correctly. No corruption. No PHP Fatal error: unserialize().
FAQ · staging
Can I stage a site with a multisite network?+
Yes. StageForge detects multisite configurations during analyze and provisions the full network in a single container. Subsite URLs and domain mappings are rewritten per-site during import. Subdomain and subdirectory installs are both supported.
Does StageForge work with managed hosts (WP Engine, Kinsta, Pressable)?+
Yes — the plugin runs inside WordPress itself, so any host that runs WP runs StageForge.
How big of a site can you stage?+
There's no hard size limit — we stage sites of any size. For sites above 2 GB, images aren't copied into the staging environment; they're referenced directly from your source site instead. That keeps staging fast and lightweight no matter how large your media library gets.
Can I get my changes back out of staging?+
Yes. Once you're happy with the result, you can download the updated version of your site — both the files and the database — and deploy it to production yourself.
