Legacy Code Discovery

Meet Your
Code Archaeologist AI Agent

Old code is expensive to keep and scary to change. The Code Archaeologist reads your live pages, lists what they load, flags heavy and unused scripts and old libraries, and ranks the fixes, so you know more about what you have before you change it.

The Infrastructure Crisis:
Legacy Code Debt Is Draining Your Budget.

Maybe your site mostly works, but every new feature takes longer than it should because nobody really understands the old code. The people who built it may be long gone, and the notes they left are outdated or missing. So every change feels risky.

According to the Consortium for Information and Software Quality, poor software quality costs U.S. businesses over $2 trillion per year. The same report also looks at technical debt, the extra cost you pay every time someone has to work on old, undocumented code.

Code with no notes is the hardest to work on. When the only person who understood it is gone, even a simple bug fix can take days to track down. The GitHub Octoverse report shows that developers spend more time reading and understanding code than writing it. A map of what you have is the place to start.

Old Code Signals Detected
// Example site analysis:
Pages read: 5
Broken internal links: 4 found
Scripts on every page: 9
Unused JavaScript (homepage): 310 KB
Outdated libraries: 3 found
Render-blocking files: 5

What the Old-Site Check Looks At.

Scripts and Files Each Page Loads

Reads up to 5 of your live pages and lists the scripts each one loads, plus the framework or site builder it can spot. You see what you are working with, even if nobody wrote it down. We work from what your site shows the public, not your private code.

Unused Code and Old Libraries

Old features and abandoned experiments pile up over the years. On the one page we test with Google PageSpeed (usually your homepage), the agent sees how much JavaScript and CSS goes unused and which old libraries load. You and your developer decide what is safe to remove.

Danger Zone List

Some parts of a site are risky to touch, like one script that every page loads, or files that block the page from showing. The agent lists these so any rebuild can go piece by piece. It also flags broken internal links and long redirect steps it finds. Pairs with our QA Automation Engineer for testing while you make changes.

Plain-Language Report

You get a short report with up to 5 issues, ranked, in words anyone can follow. Share it with your team or a new developer before you plan a redesign.

Example Before: Legacy Spaghetti
Scripts listed: none
Broken internal links: unknown
Framework: old PHP, version unknown
Scripts on every page: unknown
Risky files: not listed
// Developer confidence: zero
Example After: Checked
Scripts listed: for each page it reads
Broken internal links: listed for review
Framework: version and old libraries noted
Scripts on every page: listed
Risky files: top issues ranked
// Developer has a list to start from

Strategic Execution:
Examples of What This Agent Checks.

Logistics Company PHP Site

Example: a logistics company runs an old custom PHP site. Nobody on the team knows how the pages fit together, so every change feels risky.

The Code Archaeologist would read a sample of the public pages, show which scripts and files load where, and list the parts that look risky to change. That list helps the team plan a rebuild one piece at a time.

Insurance SaaS Cleanup Check

Example: an insurance software site has grown for years with no cleanup. Old landing pages and test features are still live, and big script files load on every page.

The Code Archaeologist would flag scripts that load on every page, how much code goes unused on the homepage, and internal links that lead to dead pages. Your developer can then check each one and remove what is safe to remove.

E-Commerce .NET Site

Example: an online store runs on an old .NET build with no written docs. New staff struggle to learn how the site fits together.

The agent would explain in plain words what the live pages load and flag outdated libraries it can see. It works from the live site only, so it will not see database code or private files.

Legacy Code - Questions Answered.

What does the Code Archaeologist actually do?

It reads a handful of your live pages (up to 5) and lists the scripts each one loads. On the one page we test with Google PageSpeed, usually your homepage, it also sees unused JavaScript and CSS, files that block the page from showing, old libraries, and heavy third-party scripts. It adds our site checks, like broken internal links and redirect steps, and explains the top issues in plain words.

Will it break my existing application?

No. The agent only reads your live site, the same way a browser does. It never changes your code. It gives you a report, and you and your developer decide what to change.

How long does an audit take?

Usually a few minutes once you start it. You get a short report with up to 5 issues, ranked, and a score from 0 to 100: things like heavy or unused scripts, old libraries, and broken internal links.

Can it handle old PHP or .NET codebases?

Yes, for the parts your live site shows the public. The agent reads the pages your server sends out, so it works no matter what language built them. It cannot see server code, databases, or private files.

What is a strangler fig migration?

It is a safe way to rebuild where new code wraps around the old system piece by piece. The old code keeps running while each section gets replaced. The agent does not do the rebuild, but its list of heavy scripts, old libraries, and broken links helps you plan one.

Do I need to give you access to my source code?

No. The agent works from your live site, the same pages anyone can visit. It does not read private GitHub repos or pages behind a login.
