Community vote — which would you rather vibe code?
The case on Obsidian
Build a desktop subset or keep paying for the real app, because replicating Obsidian's multi-platform Electron architecture, CodeMirror live-preview engine, and zero-knowledge sync is a serious multi-month engineering marathon.
Hardest parts
- Cross-platform file system performance when indexing and watching tens of thousands of local Markdown files without UI stutter
- Building a seamless Live Preview editor mode that toggles between raw syntax and rendered DOM nodes cleanly inside CodeMirror
- Zero-knowledge end-to-end client-side encryption (AES-256) for sync infrastructure
The case on Roam Research
You can build a functional personal single-user clone of Roam's core block-based graph engine, but you will hit friction getting the bidirectional query engine and sub-millisecond editor tree rendering buttery smooth.
Hardest parts
- Building a lightning-fast hierarchical tree editor where every single line is an addressable, transcludable block
- Maintaining instantaneous bi-directional link index updates across the entire database on every keystroke
- Rendering complex Datalog or recursive graph relationship queries without UI blocking or latency
