ColdFusion powers more production systems than most developers will admit. When the person who built yours moves on, finding someone who can pick it up - without breaking it - is harder than it should be.
We’ve been writing ColdFusion (cfml) in production since 2000. Not maintaining it reluctantly - building with it deliberately, because for certain systems it’s still the right tool.

We’d love to do the same for you.
We can read someone else’s ColdFusion and understand it quickly
We can fix what’s broken without touching what isn’t
We can modernise incrementally without rebuilding from scratch
We will be honest and only suggest it if a full rebuild makes more sense
It’s maintained, it’s deployed, and the businesses running it aren’t wrong to keep running it. The problem is the skills pool, not the platform.
Yes. Adobe continues to actively develop and support ColdFusion, releasing ColdFusion 2025 with modern cloud integrations and security updates. More than 300,000 developers at over 10,000 companies worldwide rely on ColdFusion for business-critical applications. It’s maintained, it’s deployed, and it’s not going anywhere.
Yes. We’ve been writing ColdFusion since 2000 and regularly work in other developers’ codebases. We can read existing CF code, understand the logic, and make changes without breaking what’s already working. We document everything we touch so you’re never stuck again.
Not necessarily. Many ColdFusion systems are perfectly viable and just need ongoing support or incremental modernization. We’ll only recommend a full rebuild if it genuinely makes more technical and financial sense than maintaining what you have. We’ll be honest about which path is right.
Yes. We have experience with both Adobe ColdFusion and the open-source Lucee CFML engine. We can assess whether migration makes sense for your system, handle the migration process, and ensure everything works correctly in the new environment.
Most ColdFusion support enquiries fall into one of these categories. We handle all of them.
Something broke and it needs fixing now. Our ColdFusion developers can diagnose the issue, fix what’s broken, and document what we changed - so you’re not stuck next time.
You don’t need a rebuild, just someone who can maintain what’s there and make incremental improvements. We provide ColdFusion development support on a retained basis.
Moving from Adobe ColdFusion to Lucee, upgrading to a current version, or rebuilding the front-end while keeping CF on the backend. We’ve done it all.

Not only did Paul deliver a great site at the front end, but he can also organise the back end that provides the lead information etc. Great communication and quick work even when I kept asking for changes.
