Lunarion Labs / Solutions / Software rescue

Software project rescue services

Software project rescue for stuck SaaS products, mobile apps and platforms, including AI-built prototypes: audit, secure, stabilize, ship.

[ The reality ]

Software rescue

Most failing software projects are not worth throwing away. What they lack is access, documentation, tests and one senior person who owns the whole thing. We read what exists, lock down what is exposed, stop the bleeding, then get the product moving again while it stays live for your customers.

[ 01 / 06 ] · We fix and finish software others left behind.

[ Our commitments ]What we guarantee.

100%in your name: code, accounts and access
0service downtime during the work
1senior lead, from first call to launch
4steps, always in this order

[ What we do ]

[ In short ]

Software project rescue means a new team takes over a stuck, failing or abandoned software project, whether built by an agency, a freelancer or an AI tool. It starts with a code audit, then secures access and data, stabilizes production and gets development moving again, usually without a full rewrite.

What are we talking about?

A project needs rescuing when money keeps going in and nothing ships: the vendor is unreachable, every release breaks something, nobody understands the code, or an AI-generated prototype cannot handle real users. A rescue is not a rewrite. It is a disciplined sequence: understand, secure, stabilize, then build.

Most failing software projects are not worth throwing away. What they lack is access, documentation, tests and one senior person who owns the whole thing. We read what exists, lock down what is exposed, stop the bleeding, then get the product moving again while it stays live for your customers.

When should you call us?

  • Your agency or freelancer stopped answering.
  • Every deploy breaks something in production.
  • Your AI-built MVP works in demos, not with real users.
  • Investors want a technical review before the next round.

How does an engagement work?

  1. Audit. Code, access, hosting and contracts. A written, costed diagnosis.
  2. Secure. Access recovered, backups in place, secrets rotated.
  3. Stabilize. Blocking bugs fixed, deploys you can trust.
  4. Ship. A clear roadmap, new features, launch.

The starting point is always the same: the Lunarion audit, at a fixed price, which gives you a written, costed diagnosis. See our four-step approach.

Software rescue: what is included

  • Code audit and technical review : Code, database, hosting, dependencies, security and running costs, written up in plain English with a costed plan.
  • Access and ownership recovery : Domain, cloud accounts, repositories, App Store and Google Play, Stripe: everything moved into your company's name, in the right order.
  • Emergency stabilization : Outages, blocking bugs, broken deploys: we stop the bleeding before touching anything else.
  • Security hardening : Leaked secrets, API keys in the code, vulnerable packages, shared admin logins: closed and rotated.
  • Refactor, not rewrite : Fragile code and outdated frameworks modernized step by step, the strangler fig way, with no big-bang rewrite.
  • AI-built app rescue : Prototypes generated by AI app builders turned into maintainable, secure production code.
  • Technical due diligence : An independent review of a codebase before you invest in it, buy it or hand it to a new team.
  • Documentation and handover : How it works, how to deploy it, where everything lives: written down, so you are never locked in again.

What drives the cost?

Every project is costed after the audit, which has a fixed price. The main factors are:

  • The size and condition of the codebase and database
  • How much access has to be recovered (domain, cloud, app stores, payments)
  • How much technical debt and how many outdated dependencies
  • Urgency: production outages come before new features

Mistakes to avoid

  • Rewriting from scratch by reflex and losing years of edge-case fixes
  • Firing the vendor before your company owns the accounts and the code
  • Adding developers to a late project (Brooks's law)
  • Shipping new features before production is stable

[ Questions ]

Frequently
asked.

Do you take over code written by another agency or freelancer?

Yes, it is our core service. We read everything before we change anything, and we tell you what is worth keeping.

Can you fix an app built with Lovable, Bolt or Base44?

Yes. We review the generated code, secure it, fix what breaks with real users and make it maintainable, without throwing away what works.

Do we have to rewrite everything?

Rarely. We keep what holds up and refactor or replace only what blocks. The audit prices each option.

Will our product go down during the rescue?

No. We work on a copy and release only after testing.

Do you do technical due diligence for investors?

Yes. You get an independent written review of code quality, security, scalability and the cost of fixing what matters.
