Top 23 Rust Build Tool Projects

rspack Description: A modern, rust-based javascript compiler that replaces webpack. What we like: Rich feature set that attempts to have feature parity with webpack; it's part of a growing ecosystem that appears well-maintained. What we don't like: It supports similar complexity in its configuration due to feature parity with webpack

Project mention: Bear generates a compilation database for Clang tooling | news.ycombinator.com | 2026-05-18

farm Description: Another rust-based bundler What we like: Excellent documentation; has been under active development for quite some time; if its history is a reliable indicator, it will (hopefully) be reliably maintained for years to come. What we don't like: The speed comparisons on their website feel dishonest - we don't like that it claims to be faster than everything but doesn't offer direct comparisons for tools like bun. (Note: we're not commenting on the accuracy of their comparisons - only noting that the comparisons aren't presented in the best light)
