cilium vs coze-loop
cilium has 25,360 GitHub stars, 4,082 forks, 1,085 open issues and last shipped today. coze-loop has 5,739 stars, 795 forks, 84 open issues and last shipped 2 days ago. cilium leads on adoption by 342% (25,360 vs 5,739 stars). cilium is written in Go under Apache-2.0; coze-loop is written in Go under Apache-2.0. cilium has attracted 16% as many forks as stars, coze-loop 14%. cilium was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (monitoring), 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.
