9 people recommended Rust Glancer in Hacker News comments, 1 had mixed feelings and none criticized it, November 2025 to October 2026. It was recommended in 2 of 12 months, in 2 threads. It does not meet the Hacker Approved badge rule.

8 of the 9 people who recommend it commented in one thread, “Rust Glancer: Rust LSP using 100x less RAM”.

**Verdict:** Rust language server that uses much less memory than rust-analyzer while staying competitive on latency. Caveat: initial indexing can use more RAM, and some tasks run slower.
