Why this exists

You shouldn't have to read 10,000 lines to change 10.

CodeMap turns an unfamiliar repo into a map you can actually see — so you find the right file in seconds, not an afternoon.

Issue Mapper

Don't browse 100 files.
Start with the right one.

Picked up your first "good first issue" and have no idea which file to open? Paste the issue URL. We walk the dependency graph, rank the files most likely to be involved, and give you a confidence score for each — so you start fixing code instead of hunting for it.

  • →Traces the issue text against your real import & call graph
  • →Falls back to AI ranking when the graph alone isn't conclusive
  • →Caches results, so a repeat lookup is instant

The map

Your whole codebase,
as a map you can read.

Pick any file and CodeMap shows exactly what it imports, what imports it, and how the pieces connect — laid out so even a 300-file hub stays readable instead of a hairball.

  • → Right-angle connectors, no tangled spaghetti
  • → Hover any node to light up its real connections
  • → Honest counts — imports vs imported-by, matched to the source

Function call graph

Change a function — safely.

Before you touch a function, see exactly who calls it and what it calls. You change only what's connected — nothing breaks downstream, and your PR doesn't get sent back.

  • → Callers ← function → callees, at a glance
  • → Read the body inline — no tab-switching
  • → Exported but uncalled? It still shows who imports it

File Dependencies

See every import relationship as a visual edge. Understand how files connect at a glance.

Function Call Graph

About to change a function? See exactly who calls it and what it calls first — so you only touch what's connected, nothing breaks downstream, and your PR doesn't get sent back.

One-Click GitHub

Every function links directly to its exact lines on GitHub. No hunting through code.

Issue → fix, end to end

A starting point — and only the
pieces that actually change.

Map an issue and you get the handful of files it touches. Open the AI chat to understand the bug in context, then jump straight to the exact function and lines to edit. You change the connected pieces — you never read the whole repo.

  • → The issue, ranked to its most likely files
  • → AI chat that answers against your real graph
  • → Inspect the affected function, then edit with confidence

Languages

Maps the languages you actually contribute to.

I made this because

I still remember staring at a huge unfamiliar repo as a beginner, wanting to contribute — but wasting so much time just trying to understand the codebase before I could even start solving a single issue. If this idea is useful to you too, I'd love to hear about it — what's confusing, what's missing, what would make this an easier on-ramp into open source.
