Custom application developers · Support and maintenance · Australia
Who looks after the app now?
The developer who built it moved on. The framework kept moving. BLACKBX developers look after custom applications and headless sites: upgrades, fixes and the features on your list, done and recorded in a logbook you own.
From $840 a month. No minimum term.
Sample, redacted. Every upgrade, fix and change, dated and in order. Yours to read any time.
The problem
Custom code, and nobody left who knows it.
The build
Built by a developer or an agency that has since moved on to the next project.
The gap
Dependencies age every month. Frameworks drop old versions. Every change waits until someone can learn the codebase.
Meanwhile
The feature list grows, and the upgrade you put off gets bigger every release.
Looking after code someone else wrote is our whole job.

Applications, headless sites and the content platforms behind them. If your stack isn’t listed, ask: a developer will tell you straight.

Who we are
Fifteen years of building websites. Now we look after them.
BLACKBX is the website service department from UnDigital (opens in a new tab): same company, same developers. Some clients send us one change a month. Others have a full team on their application every month. Our team works out of Sydney, the Sunshine Coast and Ho Chi Minh City.






Websites we’ve built and looked after across the UnDigital (opens in a new tab) group.
You’ll always deal with a person, never an unnamed inbox.
Questions
Before you ask.
Which technologies do BLACKBX developers work with?
BLACKBX developers look after custom applications and headless sites built with Next.js, React, Node.js, TypeScript and Laravel; content platforms including Statamic, Craft CMS, Sanity and Storyblok; PostgreSQL and MongoDB databases; and the APIs and integrations that connect them. We also look after WordPress, Drupal, Magento and Silverstripe sites.
Can you take over an application someone else built?
Yes. That’s most of what BLACKBX does. A developer looks through the code and how it’s deployed before we quote, and from then on every change we make is recorded in a logbook you own, so the knowledge doesn’t leave with the next developer either.
How much does custom application maintenance cost?
With BLACKBX, Maintenance starts at $840 a month + GST. Our developers keep the framework and its dependencies up to date, patch security issues, fix what breaks and build the changes on your list. We’ll give you a fixed monthly price after the first call. Every plan is monthly with no minimum term.
Do you build new applications?
We look after applications that are already built. New builds and rebuilds are done by UnDigital (opens in a new tab), the build team behind BLACKBX, and launch straight into BLACKBX.
Do we have to move our hosting?
No. Maintenance works wherever your application runs now. If you’d rather hand us the hosting too, we run applications on Google Cloud, AWS or our own Australian servers: see managed hosting.
Can we keep our current developer or agency?
Yes. Our developers do the maintenance and yours can keep access. The access is granted and logged, and the logbook records our work.
Is there a minimum term?
No. Monthly, no minimum term. The price you start on is the price you renew on.
