Case Study: Colisweb achieves better code quality and faster Scala onboarding with Codacy

How Colisweb uses Codacy to improve their code quality

Colisweb is a Lille-based startup building software-defined transportation infrastructure to enable same-day and scheduled deliveries. As the team grew and the stack moved from Ruby on Rails to Scala, Play and Akka Streams (with ES6/React), maintaining consistent code quality, visibility across the codebase and onboarding new developers unfamiliar with Scala became a major challenge.

Colisweb adopted Codacy to automate quality checks and surface bad practices, giving the team ongoing visibility and reducing manual review overhead. The tool improved code quality, streamlined onboarding by highlighting language-specific issues, required little maintenance, and became both a review and a learning aid as they scaled their technology and team.
