Codacy alternatives
7 other tools do this job. Which one is right depends on why Codacy is not working for you — so start from the reason, not the list.
Why teams leave Codacy
- Wrapping open-source linters means analysis depth depends on those tools.
- Configuration across many languages becomes fiddly.
- Less established than SonarQube in enterprise procurement.
Worth saying: Codacy is genuinely strong at this — per-developer pricing is cheaper than sonarqube for small teams on big repositories. If that is the part you rely on, switching may cost more than it saves.
If cost is the problem
Free tools and lower starting prices on the same billing unit. Usage, plan limits and maintenance can change the total cost.
ESLint
Code Quality
The JavaScript and TypeScript linter every project ends up using.
Ruff
Code Quality
Extremely fast Python linter and formatter that replaces most of the toolchain.
Biome
Code Quality
Rust-based linter and formatter that replaces ESLint and Prettier, very fast.
If you need open source
Codacy is proprietary; these are not.
