What we do
BitSalt rescues business-critical legacy applications — the kind of software that's past end-of-life, unmaintainable, and too important to abandon. The work is a structured handover: survey the legacy system, define the parity boundary, build an automated test harness against the real data, and migrate everything with tooling the client runs themselves.
Built by someone who has spent twenty years inside the infrastructure of small teams and knows what it costs when the software stops being an asset.
What we offer
Legacy application rescue
A parity-guaranteed rebuild onto a modern stack. We survey the legacy system, define what "parity" means for your application, build an automated test harness against your real data, and deliver code and documentation to your own repository. The migration command is one your team runs — with safety guards, atomic execution, and parity re-verification after the load.
How we work →Deployment, hosting & support
Available after a rescue or as a separate engagement: cloud-readiness, deployment setup, and managed hosting with ongoing maintenance and support. If what you need is to move an existing application to a cloud environment, that's a standalone engagement type too.

All checks passing doesn't mean the thing runs. With AI-assisted development, that gap isn't occasional — it's structural, baked into how agents verify work.
The Spreadsheet is the Tell
If a spreadsheet has quietly become the system of record for the work your software is supposed to do, that's not a workaround. That's a signal.
The Audit You Wish You Ran Before the Compliance Review
A compliance review asks for things you should already know about your secrets configuration. Running the audit before they ask is the difference between action items and explanations.
Tell me about your legacy application.
If you're running a business on software that's past its prime — end-of-life platform, vendor gone dark, maintenance costs that keep climbing — get in touch. Tell me what the software does and what's wrong with it. Not a pitch. Just a first conversation about what's possible.
