Codacy vs Biome
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price
From $18 per developer/month (Team, billed annually; $21 monthly)
Free tierFree and open source
Open sourceWhat drives the bill
The metric that actually scales your invoice.
Per-developer pricing rather than lines of code, which suits small teams with large codebases. Team covers up to 30 developers and 100 private repos; beyond that Business is quote-based.
Free and open source. You pay in engineering time and CI minutes.

Strengths
- Per-developer pricing is cheaper than SonarQube for small teams on big repositories.
- Bundles quality and security scanning in one PR check.
- Very quick to set up — connect a repository and it works.
- Dramatically faster than ESLint plus Prettier, which matters on pre-commit hooks.
- One binary and one config replaces two toolchains.
- Very good ESLint rule migration tooling.
Limitations
- Wrapping open-source linters means analysis depth depends on those tools.
- Configuration across many languages becomes fiddly.
- Less established than SonarQube in enterprise procurement.
- Rule coverage does not yet match ESLint's plugin ecosystem.
- No support for framework-specific plugin ecosystems at ESLint's depth.
- Young project, so expect churn.
Best for
Small and mid-sized teams wanting quality and security checks in PRs without running a server.
New JavaScript projects and teams frustrated by lint performance.
