Project context + native analyzer bridge · V1.3

Understand the error before changing the code

Paste the compiler/runtime error or stack trace, then add the related source. MNBTools can now inspect a safe project snapshot as well as pasted code: it indexes files/symbols/imports, maps stack frames back to uploaded project files, separates cascade errors, and can augment its own rules with installed native static analyzers.

No program execution

Project context optional

Add a ZIP or selected project files when the error depends on imports, namespaces, exports, modules, or another source file.

Text-only · never extracted/executed
No project files selected. Paste-only analysis still works.

V1.3 project-aware analysis: PHP · JavaScript · TypeScript · Python 300+ built-in diagnostic patterns + optional native analyzers + project file/symbol/import indexing. ZIPs are inspected in place and project code is never executed.
Ready. Tip: press Ctrl/⌘ + Enter to analyze.
How V1.3 works: MNBTools always runs its own text/rule/structural analysis. Project ZIPs are inspected without extraction; traversal paths, symlinks, binaries, oversized content, dependency/build/cache directories, .env files and private-key/credential formats are excluded. Uploaded project code is indexed as text only and never executed. Native checks still operate on a bounded temporary single-file copy, never install project dependencies, and delete the temporary workspace after analysis. Error/code contents are not written to the feature's database or audit log.
About this tool

Use Code Error Analyzer without a complicated workflow.

Paste an error or stack trace with optional source code and let MNBTools identify the likely language, error category, reported file and line, probable root cause, and practical next fixes. V1.3 adds safe ZIP/multi-file project context: MNBTools indexes source files, symbols, manifests and import/namespace relationships, maps stack frames back to project code, groups cascade issues, and still augments its own knowledge engine with optional native analyzers without running the submitted application.

How to use

01Paste the full error or stack trace

02Add the related source or optionally upload a safe project ZIP/file set

03Review reported/root-cause locations, cross-file relationships, cascade groups, confidence, and practical fixes

Workspace highlights

✓300+ deterministic PHP, JavaScript, TypeScript, and Python rules

✓Safe ZIP/multi-file project indexing with manifests, symbols, imports, namespaces, and stack-path matching

✓Cross-file root-cause correlation and cascade grouping plus optional native analyzer evidence

✓Submitted application/project code is never run; ZIPs are inspected without extraction and native tools only parse, lint, or type-check temporary source
