Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
React developers building project management and scheduling tools need Gantt visualization. No search volume, but the user survey link signals active demand collection—suggesting unmet demand among a defined audience.
Competition & the opening
Crowded space (7/10): react-gantt, Frappe Gantt, dhtmlxGantt, and commercial options exist. Gap is a drag-and-drop native React library without external dependencies or vendor lock-in.
What's hard to build
Gantt charts are hard: rendering thousands of tasks performantly, managing complex dependency graphs, drag-and-drop conflict resolution, and responsive design. Feasibility 7/10 means building a polished version requires significant frontend engineering.
Why now
React ecosystem lacks a best-in-class native Gantt component; existing libraries are either outdated or bloated with jQuery dependencies.
