# BitSalt > Rescues business-critical legacy applications that have outlived their platform. BitSalt Digital rescues business-critical legacy applications — software that's past end-of-life, unmaintainable, and too important to abandon — and delivers a parity-guaranteed rebuild the client's own team owns. ## What BitSalt does BitSalt surveys the legacy system, defines what "parity" means for the application, builds an automated test harness against the real data, and migrates everything with tooling the client's team runs themselves. Code and documentation deliver to the client's own repository. The work comes from twenty years spent building web applications and cloud infrastructure for clients across industries. ## Pages - [Home](/) — Overview of the company and how it works. - [Tools](/tools) — How we work: legacy application rescue, deployment & cloud readiness, and managed hosting/support. - [Blog](/blog) — Notes on security, operations, software, and the problems worth solving. - [About](/about) — Background on Jeff Moser and BitSalt. ## What we offer - **Legacy application rescue** — Parity-guaranteed rebuild of business-critical legacy applications onto a modern stack, delivered as code and documentation to the client's own repository. - **Deployment & cloud readiness** — Production-readiness setup, deployment pipelines, and migration to AWS, available standalone or as a rescue add-on. - **Managed hosting, maintenance & support** — Ongoing retainer to own the health of an application after a rescue, or independently. ## About Jeff Moser has spent over twenty years building web-based applications and cloud infrastructure — the full stack, from database to UI, across industries.
