flowable-engine has 9,635 GitHub stars, 2,904 forks, 411 open issues and last shipped 18 days ago. Juggle has 1,165 stars, 203 forks, 7 open issues and last shipped 2 months ago. flowable-engine leads on adoption by 727% (9,635 vs 1,165 stars). flowable-engine is written in Java under Apache-2.0; Juggle is written in Java under GPL-3.0. flowable-engine has attracted 30% as many forks as stars, Juggle 17%. flowable-engine was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (workflow-engine), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.
