VR IDEs & Commercial Code Maps

CodeSee / CodeSee Maps 2D commercial acquired — standalone product gone

CodeSee · shut down Feb 22, 2024 · acquired by GitKraken May 14, 2024 · folded into the GitKraken DevEx platform

The polished commercial "code map" — auto-generated diagrams of how a codebase's pieces connect, with the signature "stadium of arrows" overview, code-review walkthroughs, the works. It was the closest thing to a productized codebase-cartography tool with real momentum, and then it announced its own shutdown in early 2024, got bought by GitKraken weeks later, and dissolved into their paid DevEx platform. codesee.io still resolves; the standalone product does not.

CodeScene 2D dashboards commercial · free tier alive

Adam Tornhill / Empear → CodeScene · the commercial descendant of "Your Code as a Crime Scene" · free tier for individuals/small teams; paid from ~€18/mo per active author

Mature, actively sold, genuinely good — and not spatial. CodeScene mines git history for "behavioral" signals (hotspots = high churn × high complexity, knowledge maps colored by author, change coupling, code health trends, the "X-Ray" function-level drill-down) and renders them as 2D circle-packing diagrams and dashboards. It's the productized form of Tornhill's crime-scene tooling. Worth listing here precisely to mark the boundary: this is the state of the art in "make the whole codebase legible at a glance," and it does it in 2D, with circles, deliberately.

CAST Imaging 2D zoomable map enterprise alive

CAST Software · enterprise code cartography · handles systems up to ~60M LOC; AWS Marketplace listing

The big-enterprise answer to "we have sixty million lines and nobody understands them": a browser-based, zoomable interactive map that descends from UI layers through application logic to the database, with elements rendered as nodes and icons. It scales further than anything else here — but it renders the system as a diagram of components, not as source text. The "code cartography" name is doing a lot of work; it's a very good architecture map.

AppMap runtime maps alive · OSS

AppMap (getappmap) · open source, actively developed across Java / Python / Node agents · free; lives inside VS Code and JetBrains

Different category, included so the boundary is clear: AppMap records a program running and draws the resulting call sequences and dependency maps inside your editor. It's runtime-dynamic, not whole-repo-static — the map is "what executed during this test," not "what the codebase is." Genuinely useful, genuinely maintained, genuinely not the thing glyph3d-js does.

CodeMR 2D dashboards commercial · crippled community edition

CodeMR · Eclipse + IntelliJ plugins (Java / Scala / Kotlin / C++) · alive, but the free edition caps at ~50 files / ~60 classes — effectively a demo

Static quality analysis with dependency and complexity dashboards. Listed mainly because it shows up in any "code visualization tools" search; the community edition is too small to use on a real project, and the paid edition still produces 2D dashboards, not a spatial scene.

Sourcetrail renders text (in a pane) 2D graph dead upstream, alive in a fork

Coati Software → community forks · original archived Dec 14, 2021 (final release 2021.4.19) · the petermost/Sourcetrail fork shipped release 2025.12.8 — 3000+ commits, Clang/LLVM 20, Qt 6.9, VS 2026

The best-loved of the code-graph navigators: click a symbol, see its callers and callees as a graph on one side and the actual source on the other, for C/C++/Java/Python. Coati Software shut it down and open-sourced it in 2021; the living continuation is the petermost fork, which is genuinely maintained. Not spatial — but the closest thing to a polished, interactive, whole-codebase symbol explorer that still works, and a good reference for "what does navigating a real codebase's structure feel like when someone sweated the UX."

CodeCompass renders text 2D alive

Ericsson + ELTE Budapest · ICSE / SANER tool track 2018 · actively maintained; used at industrial scale inside Ericsson

A web-based, server-backed codebase explorer for C/C++/Java/Python: full source with deep cross-references, call graphs, build-system views, version-control overlays. The layout is conventional (source pane + side panels + graph popups), not spatial — but it ingests genuinely huge codebases and it's one of the few tools here that an actual large company runs in anger.

emerge 2D graph alive · OSS

Glenn Lasse Tews (glato) · latest release v2.0.7, July 2024 · MIT; pip install emerge-viz or Docker

Point it at a source directory in ~12 languages and it produces a browser-based, force-directed dependency graph plus metrics. Solid, small, maintained — and a graph, not a city or a text-scape. A reasonable "I just want to see the module structure" tool.

Sourcegraph renders text (search results & file views) 2D alive · independent · well-funded

Sourcegraph · Code Search · Cody · Amp · independent (not acquired), substantial revenue

Worth a line only to confirm what you already assumed: Sourcegraph indexes enormous codebases and exposes that index as search results and file views and as fuel for AI tools. There is no map view, no spatial view, no city. The "code graph" is an internal data structure, not a thing you fly through. If you were wondering whether the biggest player in "understand a large codebase" had quietly built the spatial thing — they haven't.

codemap.app · CodeAtlas · VS Code "Code Map" 2D assorted, mostly dormant

various small tools

The long tail of "call-graph in a sidebar": codemap.app (multi-language 2D call graphs, last visible activity around 2020/2024, treat as link-rot risk), CodeAtlas (old Sublime plugin riding on the Understand engine; a GitHub Action wrapper survives it), and the oleg-shilo.codemap VS Code extension (a lightweight per-file symbol outline — useful, but it's a file outline, not a codebase map). None of these scale to "the whole repo as one view"; all of them are worth a glance for UI ideas.

Glamorous Toolkit / Moose / Roassal renders text (as moldable objects) 2D alive — unusually active

feenk / the Pharo community · Pharo + Rust; "Bloc" rendering engine; Roassal visualization engine; "Moldable Development" · multiple releases a week; steep Smalltalk learning curve

The serious software-analysis platform you can actually download and point at a codebase today. Moose parses and models systems; Roassal draws the visualizations; Glamorous Toolkit wraps it all in a "moldable" environment where every object — including every chunk of source — gets bespoke, composable views, and the text editor itself was rebuilt (in Bloc) to carry attribute spans, cursor indexes, and live inline previews. It's genuinely powerful and genuinely alive.

It's also not a "whole repo, all at once, spatially" tool — it's per-object and analytical, it has known performance pain on very large text buffers, and it has no repo-scale text-wall view. The right way to file it: the closest thing to a peer on rich, programmable, annotated source, on a completely different axis from scale.

GitHub Codespaces · vscode.dev · Gitpod · CodeSandbox renders text (one file at a time) 2D alive

the "VS Code, but in a browser / in the cloud" category

You know all of these; this is here so the survey is complete. Every one of them is a remote or web build of VS Code (or an equivalent): file tree on the left, tabs across the top, one file open at a time. Zero whole-repo spatial rendering. Whatever else they do — and they do a lot — none of them competes with, or even gestures at, the thing in Volume 01. "Code on the web" turned out to mean "the editor, but somewhere else," not "the codebase, as a place."
