CocoIndex vs go-streams
CocoIndex has 11,566 GitHub stars, 899 forks, 83 open issues and last shipped 2 days ago. go-streams has 2,172 stars, 174 forks, 11 open issues and last shipped 8 months ago. CocoIndex leads on adoption by 433% (11,566 vs 2,172 stars). CocoIndex is written in Rust under Apache-2.0; go-streams is written in Go under MIT. CocoIndex has attracted 8% as many forks as stars, go-streams 8%. CocoIndex was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (etl), 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.

About go-streams
go streams is a lightweight stream processing library for Go. It lives in the Go data engineering and analytics ecosystem, and it lets programmers define declarative data pipelines from composable sources, flows, and sinks. The core module has no external dependencies, so the basic pipeline model does not require a broker, cloud service, or third party runtime.
