Inngest leads on adoption by 416% (6,021 vs 1,166 stars). Inngest is written in Go under a custom or non-standard licence; Juggle is written in Java under GPL-3.0. Inngest has attracted 6% as many forks as stars, Juggle 17%. Inngest was the more recently maintained of the two, and both are self-hostable with no licence fee.
