Diagrams
Diagram tools in this list are either a text language or a drawing canvas. A text language belongs in git. A canvas belongs in a meeting. Treating them as the same alternative is how teams pick a tool they will not use.
Open source rows can be checked into a repo and rendered in CI. Proprietary canvases are accounts and sharing links. If the diagram has to survive a vendor shutdown, prefer the row whose license lets you keep the source. The since-year is a hint about how much syntax and how many examples already exist.
