Figma is published by Figma. This page compares only projects with an explicit relationship to it; shared categories alone never create an alternative claim.
Recommended order uses OpenAlternative organic alternatives v4 (version 4). Relationship confidence, category fit, logarithmic popularity, as-of maintenance and freshness, bounded anomaly quarantine, and known-data penalties. Payment is fixed at zero.
A hard constraint removes a Project only when its stored fact is known and conflicts. Unknown facts remain visible, are called out below, and never become a negative claim.
Design and prototyping built on open web standards
Penpot stores designs as SVG and uses CSS layout primitives - flex and grid - as its layout model, so what a designer builds maps onto what a developer implements rather than needing translation.
Collaborative whiteboard with a hand-drawn look
Excalidraw's sketchy rendering is not decoration. Diagrams that look provisional invite comment, where a crisp vector diagram signals a decision already made, so it is unusually good at the early part of a design conversation.
Groups appear only when at least two credible projects qualify.
