CLUSTER DESIGN-OFFLINE-OPEN · 7 ENTRIES · EARLIEST ENTRY 2026-03-17

Open-source offline design tools

This cluster comprises open-source desktop applications for creating and prototyping interface designs, with local-first offline editing as a common theme. The dated history is too thin to read a shape from—it predates the index or its members are undated. Among traction leaders, figcraft leads with 541 stars, while VectorSpace and baren have far fewer.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
