About flowgo

flowgo

flowgo is an open source tool. It's maps-as-code: zoomable, nested mind-maps and system maps that round-trip with a plain-text .flowgo file. Sketch, drill in, and version your thinking. The format, the editor and the command-line app are all open source, and the file is yours — plain text you can keep in your own repository.

Licence

Source

Format

.flowgo: plain text, diffable, backward-compatible; the round-trip through it stays lossless

Runs

In a browser, or from one binary on your own machine: flowgo mindmap.flowgo serves the same editor against a file on your disk

Costs

Nothing, wherever you run it

flowgo-map.com

flowgo-map.com is a hosted service for it, built by Exaptation. It runs the editor for you, so you can start a map with no account, share one with a link, and work on it with other people. Alpha — this hosted service carries no uptime guarantee. The tool above is unaffected by that: it is open source and runs without this site.
