Flowchart and diagram editors

This cluster covers diagram editors for creating flowcharts, algorithm diagrams, mind maps, and system diagrams, with both desktop and browser-based offerings. The dated history shows single entries scattered across 2015, 2018, and 2021, followed by four entries in the first half of 2026. Traction is led by academic_plotting with 4 stars, followed by nodeflow with 2 and nodeweave-studio with 0.

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 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
