A digital twin that watches over your website, keeps it up to date and protects it from attacks and outages.
With it, updates and changes are tested in advance and go live without interruption. Vulnerabilities are closed early, and your customers notice none of it.
On most websites every change goes live straight away, without a rehearsal. Updates are tedious, risky and tend to get pushed back. Known security holes stay open for weeks. If that goes wrong one day, your customers will probably notice before you do.
The Doppelgänger changes that: a test environment that always mirrors your live website. With it, I keep your website up to date, monitor its condition and prevent outages. You don’t have to take care of anything. What used to be reserved for corporations with their own IT, I now make possible for small and mid-sized businesses too.
Since our store got its Doppelgänger, where Julian checks every update and every change first, the store has been running absolutely smoothly. Updates are no longer a big project we keep putting off. We see and test new features there before they go live, and only approve them once everything is right. It has made our work noticeably more productive.
The Doppelgänger is an exact copy of your website, with all its content, images and settings. This is where things are built, tested and signed off, while the live website keeps running undisturbed. A regular sync keeps it up to date.
What stays as it is: your hosting, your domain, your logins.
Texts, design or updates: everything happens on the Doppelgänger first, unnoticed by your visitors.
New pages, a redesign, a campaign: on the Doppelgänger you experience everything in advance as a real website, to try out, show around and sign off. It only goes live once you are convinced.
No manual uploads, no forgotten files. The new version is prepared in full and switched over in an instant.
Content, orders and customer data from the live website can be brought over at any time, anonymized in line with the GDPR.
Even a major WordPress or Shopware update is run through in full before your customers see it.
An attack is spotted quickly, every change is visible and can be undone. That keeps the damage small.
AI-assisted programs scan the entire internet around the clock for vulnerable websites. They don’t ask how big your company is, only which version you run. If you update promptly, you close the gap before it is found.
A known vulnerability is often exploited automatically within a few hours, long before “we’ll update when we get around to it”.
Automated attacks don’t pick a target. They hit every website with a known vulnerability.
Spam, malware, lost rankings, days offline. Cleaning up costs many times more than prevention.
Today, the time between a vulnerability being published and the first attack is often just hours. A quarterly update can no longer keep up.
Every change to your website goes into the dossier: when, what, by whom. So you can always trace what happened, even years later.
Every change with date, description and author, whether from you, your team, an agency or a freelancer. So you keep track even with many people involved.
If something goes wrong, the website is switched back to the last clean version. Individual changes can be undone selectively, without losing anyone else’s work.
New staff or a new agency start with a documented website and a complete dossier. No knowledge locked in one person’s head, no dependence on individuals.
An example calculation: four update rounds a year by hand, the Doppelgänger and a single incident compared.
Per update round less than two hours of a developer’s time, and every round is tested first.Usually costs about as much as four rounds by hand, but updates three times as often and checks every update on the copy first.Less than four update rounds a year at an agency, and monthly instead of quarterly.
For a week the website redirected visitors to casino sites. Five websites on the same server were infected, and so were the host’s backups.For a week the website redirected visitors to casino sites.

Example: 3 to 5 hours per round for WordPress with WooCommerce or a page builder, at €100 an hour. Example: 6 to 8 hours per round for minor updates (an agency’s estimate), at an agency rate of €130. Incident costs: the example calculation from the case, without lost sales. Sources: freelancermap 2025, Patchstack 2026.
You give me one login, and I set up everything else.
SSH access or a login to your hosting control panel is enough. That is all I need from you.
I copy your website or store to the Doppelgänger, install the plugin and set up the nightly checks. After two to three days, everything is ready.
Costs depend on your project. After a first review of your system, you get a quote.
In a short conversation I find out what your website needs, how the switch works and what it costs. No obligation, no rush.
