Apache SkyWalking vs tracing
Apache SkyWalking has 24,958 GitHub stars, 6,633 forks, 41 open issues and last shipped 3 days ago. tracing has 6,880 stars, 933 forks, 887 open issues and last shipped 4 months ago. Apache SkyWalking leads on adoption by 263% (24,958 vs 6,880 stars). Apache SkyWalking is written in Java under Apache-2.0; tracing is written in Rust under MIT. Apache SkyWalking has attracted 27% as many forks as stars, tracing 14%. Apache SkyWalking was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (logging), 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.
