Who This Is For

Backend engineers and technical leads use this template to manage API projects from schema design to production deployment. It includes dedicated phases for security testing and documentation, which are frequently underestimated in API projects.

Why Use LoopGantt

API projects have complex interdependencies between schema design, implementation, and documentation. LoopGantt tracks these dependencies visually so you can see exactly when documentation needs to start based on development progress, and shifts security testing dates automatically when code takes longer.
