Rework my legacy system
“Our system has run for years. Whoever built it is gone, there’s no documentation, and every change is a risk, so nobody changes anything.”
Companies with an application nobody fully understands any more.
X-ray my code →Before you commit: free
- 1.You enter a public repository link (a private one by arrangement). The code X-ray shows stack, services, data model and exposure, with file and line. Your code is read, never run.
- 2.You can also drop a database schema or an OpenAPI file into the same box.
The steps, and who decides
- 1TodayYou ask for the full map of your code. No obligation, nothing to pay.You
- 2Map and callAtlas reads all of the code; a person reviews the map before you get it. In 30 minutes we go through it: what stays, what is adapted, what is rebuilt.Us, then you and us
- 3Assessment and planEvery requirement with its effort and reason, then a fixed price confirmed by a person. Nothing is built before you approve the plan.You approve
- 4Build in stepsWith your approval comes the phase 1 invoice (30 %). We move it step by step; each stage is checked.You pay
- 5PreviewYou try the result before it replaces anything. On your approval: phase 2 (40 %).You approve
- 6Go-liveIt goes live and we hand it over. Phase 3 (30 %); care begins if you want it.Us, with you
You get
- The full map of your system: components and their jobs, data flows, features, every risk with file and line, reviewed by a person
- What stays, what is adapted, what is rebuilt, each with effort and reason
- A fixed price after the assessment, before anything is built
- Your code is read, never run
We need from you
- Read access: a public repository, or a private one arranged with us
- What you have in mind: understand it, modernise it, rebuild it, or have us run it
- Who knows the system today, if anyone
- 30 minutes for our call, to go through the map
Price and terms
- Asking for the full map: no obligation; we reply in person with scope and price.
- The rework: a fixed price after the assessment, before anything is built; paid 30 / 40 / 30.
- Term and notice
- Care runs for at least 12 months from go-live and can be cancelled with 1 month’s notice to the end of that term. Paid yearly, it renews for 12 months at a time unless you cancel or switch to monthly billing with 1 month’s notice before renewal. Paid monthly, it continues month to month with 1 month’s notice.
- If you stop
- Phase 1 (30 %) is due with your plan approval and is not refunded once the build has started. If you stop before approving the preview, phases 2 and 3 are never due.
- Changes
- Two rounds of changes on the preview are included before you approve the go-live.
- Leaving
- Your content, pictures and domain stay yours. On leaving you receive a full export of your content data and pictures within 14 days, and you point your domain wherever you like. No exit fee.
Where you land
- Right away: the X-ray on screen, and the next steps by email when you ask for the map.
- With the plan: your project room, with every stage, your approvals and invoices.

Questions about: Rework my legacy system
Do you run my code?
Never. The code is read, not executed: nothing from your repository runs on our side.
What does the free code X-ray show?
The stack, services, data model, routes and what is exposed, each with file and line, plus a first architecture map you can download.
My repository is private. Can you still read it?
The public X-ray reads public GitHub repositories. For a private one we arrange read access with you. You can also drop a database schema or an OpenAPI file into the box on the check page.
What is in the full map, and how fast?
Components and their jobs, data flows, features and every risk with file and line, reviewed by a person before you get it. The Audit (full map, supply-chain scan and action plan) comes within two working days.
Do you rebuild everything?
Only what has to be. The assessment shows per requirement what stays, what is adapted and what is rebuilt, each with effort and reason, and a fixed price before anything is built.
How is the rework paid?
Asking for the full map is without obligation. The rework has a fixed price after the assessment, paid 30 / 40 / 30: with the plan, at the preview, at go-live.
Which of the six ways is right for me?
Pick the sentence that sounds like you. An old website: move it. A new website or tool: build it. Code nobody understands any more: rework the legacy system. Routine work eating your team’s time: agentify one process. Customers asking how you use AI: Synaptwin. Customers or auditors asking for security evidence: Viwago. Unsure? Every way starts free, so start with the check that fits best and we tell you if another way suits you better.
What does it cost to start?
Nothing. The website check, the code X-ray, the company scan, the Agentify walk-through, Synaptwin’s first call and Viwago’s sign-up are free. You see the steps, the price and the terms before you commit to anything.
Free, and no sign-up, until you decide.
