#1 · ESLint Foundation · Crowd Favorite
ESLint with @typescript-eslint (Strict Config)
Free
The philosophical gatekeeper that questions your type safety obsession
- ✓ Infinitely configurable—you can make it as paranoid as you want
- ✓ Catches legitimate bugs before runtime
- ✓ Huge community means rules for every edge case
- ✗ Initial setup takes 4+ hours if you want it actually strict
- ✗ False positives on legitimate patterns require constant rule tweaking
#2 · Biome Team · Hidden Gem
Biome (Rust-powered)
Free
The radical alternative that comes with opinions baked in—no bikeshedding allowed
- ✓ 10x faster than ESLint because it's written in Rust
- ✓ Zero-config setup actually works for most teams
- ✓ Opinionated defaults mean less arguing about formatting
- ✗ Still immature—ecosystem not as rich as ESLint yet
- ✗ Less granular control if you need specific rule tweaks
#3 · PylintLab
Pylint (Python)
Free
Tells you things about your Python code you didn't want to know—in the best way
- ✓ Incredibly thorough static analysis catches real logic errors
- ✓ Deeply configurable message types
- ✓ Mature project with decades of battle-testing
- ✗ Can feel like a helicopter parent—some rules make you want to scream
- ✗ Performance degrades on large codebases
#4 · Realm · Best Value
SwiftLint
Free
Forces iOS developers to write boring, maintainable code instead of clever code
- ✓ Swift-specific rules that actually prevent crashes
- ✓ Easy CI/CD integration
- ✓ Growing community backing

- ✓ Developers actually listen to Clippy because it's right ~99% of the time
