# sccache

11 Hacker News commenters recommended sccache and 7 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months.

**Verdict:** Recommended for easy setup and faster rebuilds by caching compiler output in S3, Redis or memcache. Critics report low cache hit rates.

## Why people recommend it

- Speeds up rebuilds by caching (3 comments): "tools like sccache can dramatically reduce rebuild times by caching artifacts" ([source](https://news.ycombinator.com/item?id=48097693)) "use sccache in ci to cut down on compile times" ([source](https://news.ycombinator.com/item?id=50266249)) "sccache for crate compilation caching" ([source](https://news.ycombinator.com/item?id=48516913))
- Used in CI and shared builds (2 comments): "If you give it another go, I would recommend a shared sccache." ([source](https://news.ycombinator.com/item?id=49923958)) "use sccache in ci to cut down on compile times" ([source](https://news.ycombinator.com/item?id=50266249))

## What people warn about

- Cache misses still recompile crates (2 comments): "even when I setup sccache for our team and our cache hit rate remained below 20%" ([source](https://news.ycombinator.com/item?id=48842176)) "Even that doesn't fully avoid recompilation of the same crate" ([source](https://news.ycombinator.com/item?id=49925200))
- Slow compiles and caching overhead (2 comments): "Even with sscache the compile times are not great" ([source](https://news.ycombinator.com/item?id=48277196)) "caching jobs took longer than some build steps" ([source](https://news.ycombinator.com/item?id=50266492))
- Poor scaling and capped parallel jobs (2 comments): "there's a hard cap on parallel jobs" ([source](https://news.ycombinator.com/item?id=47280396)) "find it doesn't scale well" ([source](https://news.ycombinator.com/item?id=47278423))
