Crater vs Bors

Developers should use Crater when working on Rust compiler development, library maintenance, or large Rust projects to prevent regressions and ensure compatibility across updates meets developers should use bors when working on collaborative projects with multiple contributors to enforce a 'never break master' policy and reduce integration issues. Here's our take.

Crater

Nice Pick

Developers should use Crater when working on Rust compiler development, library maintenance, or large Rust projects to prevent regressions and ensure compatibility across updates

Pros

• It is particularly valuable for testing changes to the Rust language or standard library, as it provides empirical data on how modifications impact the broader ecosystem
• Related to: rust, cargo

Cons

• Specific tradeoffs depend on your use case

Bors

Developers should use Bors when working on collaborative projects with multiple contributors to enforce a 'never break master' policy and reduce integration issues

Pros

• It is particularly useful for open-source projects, large teams, or any codebase where maintaining a stable main branch is critical, as it automates the merge process and ensures all tests pass before changes are integrated
• Related to: github-actions, continuous-integration

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Crater if: You want it is particularly valuable for testing changes to the rust language or standard library, as it provides empirical data on how modifications impact the broader ecosystem and can live with specific tradeoffs depend on your use case.

Use Bors if: You prioritize it is particularly useful for open-source projects, large teams, or any codebase where maintaining a stable main branch is critical, as it automates the merge process and ensures all tests pass before changes are integrated over what Crater offers.

The Bottom Line

Crater wins

Developers should use Crater when working on Rust compiler development, library maintenance, or large Rust projects to prevent regressions and ensure compatibility across updates
