Everything Cargo does, and then some.

Rune builds your existing Cargo projects with rustc directly — and adds a cache shared by every project and machine, a stronger test runner and supply-chain checks, in one binary.

CachingNothing is compiled twice.Every compiled crate goes into a content-addressable store shared by every project, branch, profile and machine. Same inputs, same artifact — reused in milliseconds.Learn more
TestingA test runner you can trust.Testing starts while the build is still running, with retries, flaky-test detection, re-runs of what failed, cached results and coverage built in.Learn more
CI and teamsOne cache for every machine.Share the store between laptops and CI through a directory or Cairn. A developer with an empty store restores a whole workspace in under a second.Learn more
Supply chainBuild scripts stay in their sandbox.Sandboxed build scripts and proc-macros, advisories with the path and the fix, SBOMs, and a view of every crate that runs code while you build.Learn more
PerformanceThe whole machine, not one core at a time.Pipelined compilation on every core under one jobserver, memory-aware scheduling, and a timeline of the chain that sets the pace.Learn more
Rune vs CargoSame project, less waiting.What stays the same, what Rune adds, how they measure up — and where Cargo is still ahead.Compare

Nothing to migrate and nothing to undo: your project keeps working with plain cargo.
