JetBrains Details a Rust Rewrite of Core Tooling
JetBrains published a blog post outlining its decision to rewrite parts of its tooling stack in Rust, joining a growing list of companies moving performance-sensitive code away from older languages like Java, C++, or Go. While details in the original writeup are light, the move fits a broader industry pattern: teams building IDEs, linters, and build tools increasingly reach for Rust when they need speed, memory safety, and predictable performance without a garbage collector.
The post generated modest but active discussion on Hacker News, with commenters weighing in on tradeoffs between rewrite risk and long-term maintainability gains.
For a company like JetBrains, whose products live or die by editor responsiveness and indexing speed, shaving latency out of core paths has direct product value for millions of developers using tools like IntelliJ, PyCharm, and Rider.
