Score: 6.3/10 (Innovation: 7, Technical: 6, Documentation: 4, Utility: 6)

Mainline is a project management tool that rejects story points, backlogs, and surveillance, instead using a story map, tracking unreleased work as inventory, and making collaboration patterns like pairing visible. It aims to counter dark-agile practices and promote healthier engineering workflows. Built as a boring monolith with Ruby, Roda, and Sequel, it integrates with GitHub to track CI/CD health.

Target audience: engineering managers, software teams, DevOps engineers
