# Gossamer programming language

5 Hacker News commenters recommended Gossamer programming language and 11 criticized it, November 2025 to November 2026. It was recommended in 1 of 13 months.

**Verdict:** Free Rust-like language with Rust function calls and goroutine-style concurrency; people like its design, but critics doubt claims of preemption, memory and ecosystem.

## Why people recommend it

- Easy Rust interop and similar syntax (2 comments): "The syntax similarities help make for a more painless two language approach." ([source](https://news.ycombinator.com/item?id=48720903)) "All three points are erased by its ability to call Rust functions" ([source](https://news.ycombinator.com/item?id=48700125))
- Appealing language design (2 comments): "the actual language design seems quite nice" ([source](https://news.ycombinator.com/item?id=48692340)) "If Gossamer were to drop that claim, then I'd say it looks impressive to me." ([source](https://news.ycombinator.com/item?id=48694018))

## What people warn about

- Concurrency and memory claims overstated (3 comments): "Green threads are not impressive if they are not preemptive." ([source](https://news.ycombinator.com/item?id=48694407)) "That means it doesn't have "pause free" memory." ([source](https://news.ycombinator.com/item?id=48691065)) "m:n scheduled by io is .. 2000s-era" ([source](https://news.ycombinator.com/item?id=48691477))
- Suspected vibe-coded, doubtful ecosystem (2 comments): "Even on the off chance this project is not entirely vibe coded how could it ever build an ecosystem?" ([source](https://news.ycombinator.com/item?id=48692445)) "It's clearly vibecoded if you look at the commit history." ([source](https://news.ycombinator.com/item?id=48691427))
- Rust overhead and flavour claims questioned (3 comments): "Calling this rust flavored (or even a systems programming language) seems a bit bold." ([source](https://news.ycombinator.com/item?id=48693124)) "it isn't used for its own compiler. The compiler is written in Rust." ([source](https://news.ycombinator.com/item?id=48693784)) "it's going to have more overhead than rust when it's running" ([source](https://news.ycombinator.com/item?id=48693468))
- Web routing example looks awkward (2 comments): "The web-routing thing is especially gross because a different example shows off pattern-matching." ([source](https://news.ycombinator.com/item?id=48691920)) "That web routing example is absolutely gross to my eye" ([source](https://news.ycombinator.com/item?id=48691373))
