Legacy Code Risk Scanner
Start with a static security and modernization risk snapshot before you modernize, rebuild, or recode old software.
Modernize Agent AI looks for security smells, unsafe patterns, exposed secrets, callback risks, old dependencies, outdated runtimes, and modernization blockers so the next step is based on evidence instead of guesswork.
This is a Preview Scan powered by static heuristic indicators that run in your browser. It is not a full AI modernization engine yet — the AI Deep Scan and project-level recoding workflows are in early access. Use this preview to surface possible modernization blockers, complexity hotspots, hardcoded configuration risks, outdated patterns, and documentation-recovery candidates — all framed as signals for human review, not guaranteed findings.

What it checks
- possible secrets and credentials
- unsafe SQL patterns
- dynamic execution risks
- shell and file operation risks
- callback and phone-home URLs
- old dependencies and bundled libraries
- outdated framework and runtime signals
- suspicious install and config files
- modernization blockers
What you receive
- risk summary
- finding list
- severity and confidence
- source context
- likely false-positive notes where applicable
- modernization impact
- recommended next action
Honest limitations
- static analysis only
- no code execution
- no exploit attempts
- not a penetration test
- not a full security audit
- findings require human review
- false positives are possible
- qualified security review may still be needed
Advanced defensive AI review may be available for authorized projects and higher-tier plans when configured. All findings require human review.

Project Plan
No mock reports. No fake scan results. No unsupported security claims. Every report is generated from real source evidence, a completed scan, or an explicit explanation of why no report was produced.
If a scan cannot produce a report, Modernize Agent AI will not fabricate one. It will explain what happened, why no report was generated, what you can do next, and whether the issue needs user action, owner/admin action, system configuration, or manual review.

Project Plan
Some codebases may be candidates for careful modernization.
Some may be better treated as source evidence for a clean-room rebuild.
Some may be too risky to revive directly.
Modernization Is More Than Translation
Modernize Agent AI does not treat code translation as proof of modernization. A system may compile and still be unsafe, behaviorally wrong, brittle, or unready for production. The first step is evidence: risk signals, dependencies, callbacks, runtime age, unsafe patterns, and modernization blockers.
Future roadmap areas include memory-safe modernization readiness, C/C++ to Rust readiness assessment, behavior-preservation planning, and containment-first recommendations for systems that should be isolated before they are rewritten. Generated code should be treated as untrusted until there is evidence that it preserves desired behavior.

Project Plan
“Contain” is a roadmap decision category: some risky legacy systems should first be isolated, wrapped, sandboxed, or profiled while a safer modernization path is planned. It is not an implemented report outcome today.
Read-only by design
Preview scans are designed to inspect code text for modernization signals without executing the code or modifying files. Raw source code is not stored by the public demo scanner. Project-level scans require explicit early-access review and additional security controls.
- No code execution
- No production changes
- No public display of code
- No raw source stored for preview scans
- Secrets are redacted from results
- Aggregate metrics only
Run a preview risk scan
Paste a snippet, upload a small legacy file, or upload a WordPress plugin zip. All analysis runs in your browser using static indicators only. AI Deep Scan coming soon.
The Legacy Code Risk Scanner is not available to the public yet. Modernize Agent AI is currently being tested privately by the founder and approved testers.
Scanner is idle. Submit a snippet, file, or plugin zip to start a preview scan.
Want a deeper modernization report?
Modernize Agent AI is preparing early access for project-level legacy code risk scanning, documentation recovery, and AI-guided recoding workflows. The Preview Scan is the first step — saved projects, exports, modernization readiness reports, and rebuild/recode/reject planning are subscription features. Billing is not connected yet, so plan actions record interest and access requests only.
Need to scan a full codebase?
Project-level scans are planned for early access. Tell us about your codebase and modernization problem and we’ll reach out as the deeper scanner becomes available.
- Deeper static analysis across many files
- Documentation recovery candidates
- Migration blocker mapping
- Human-reviewed modernization plan
Realization Helpers
Did you come here for one problem but actually have another?
Legacy software problems rarely stay in one lane. These are the most common shifts we see.
“I only wanted to know if this old code is risky.”
You may also need a modernization readiness report.
“I have an old WordPress plugin or PHP app.”
You may need a rebuild assessment instead of direct code modernization.
“I found an old software package on a backup drive.”
You may need an archived software intake and opportunity report.
“I bought software years ago and the vendor disappeared.”
You may need source evidence review, a callback audit, license-risk notes, and a clean-room rebuild plan.
“I want a new app that does what an old package used to do.”
You may need feature extraction and a clean-room blueprint.
“I'm worried about hidden callbacks.”
You may need a callback / phone-home audit.
“I need to move a site off a builder or old host.”
You may need site portability planning.
“I want to understand a competitor's product structure.”
You may need public feature intelligence and a clean-room build brief.
Pathfinder
What brought you here?
Pick the closest match. No login required, and nothing is collected here — this only points you at a starting path.
This preview scan is a directional assessment based on static indicators. It is not a full security audit, compliance review, compiler validation, or guaranteed modernization plan. Modernize Agent AI is being built for human-reviewed modernization workflows.
