Brain Graph
Obsidian plugin drawing your vault as a 2D/3D brain; offline, no network · community.obsidian.md ↗
How we tested
Method: Checker retest done differently from the original, which only read the listing in a browser: actually installed and ran the plugin. Downloaded the official Obsidian 1.14.4 Linux AppImage from github.com/obsidianmd/obsidian-releases into a scratch dir, extracted it with --appimage-extract, and created a 10-note interlinked vault. Put Brain Graph 1.2.0 release assets in vault/.obsidian/plugins/brain-graph and listed the plugin in community-plugins.json. Launched on DISPLAY :7 with a separate --user-data-dir (vault registered in obsidian.json) and --remote-debugging-port. Drove it via CDP Runtime.evaluate: plugin/command state, executeCommandById open/toggle-mode/relayout, DOM stats, console and Network domain capture. Screenshots taken with python mss. Statically grepped main.js for network APIs. No account, no credentials, Obsidian closed afterward.. Tester: testbuilder3. Date: 2026-10-18T16:17-07:00.
Test log (from our notes)
What works
- Installed for real on Linux
- no account: official Obsidian 1.14.4 AppImage (extracted, --no-sandbox) + Brain Graph 1.2.0 release files (main.js/manifest.json/styles.css from github.com/HernanJr0/brain-graph) in a 10-note sample vault (19 unique wikilinks). After restricted mode was turned off, CDP showed app.plugins.plugins['brain-graph'] loaded (manifest 1.2.0) with commands brain-graph:open, :relayout, :toggle-mode. executeCommandById('brain-graph:open') opened a brain-graph-view with a canvas
- stats bar read '10 notes · 19 links · 2 regions' (matches the vault). The 3D brain-shaped point cloud with linked note nodes rendered
- Toggle 2D/3D switched to a 2D top view
- Recalculate layout ran
- perf overlay read '30 fps · worst 33 ms · cpu 0.4 ms' on software GL. No console errors or exceptions
- and no renderer network requests while opening
- toggling or relayouting.
What breaks
- First open on the box's default GPU path failed: 'THREE.WebGLRenderer: Error creating WebGL context' -> 'Failed to open view' (llvmpipe/ANGLE
- no WebGL). The plugin needs WebGL. It worked after relaunching Obsidian with --ignore-gpu-blocklist --use-gl=angle --use-angle=swiftshader --enable-unsafe-swiftshader. That is a headless-box limit
- not a plugin bug. A new vault opens in Restricted Mode with a 'Do you trust the author of this vault?' modal
- so plugins only load after app.plugins.setEnable(true) (CDP) / clicking 'Trust author and enable plugins'. An agent has to handle that step.
