How it got here

2009–2017 · modularization and admin overhaul

The project underwent a major architectural shift, migrating from a monolithic structure to a modular OTP application layout with a Rebar3 build system. This period focused on replacing legacy components like Webmachine and ErlyDTL with modern alternatives such as Cowboy and Cotonic, while simultaneously rebuilding the administrative interface with granular access control and new management tools.

2018–2026 · Security, extensibility, and developer tooling

This period focused on hardening the platform's security posture by introducing two-factor authentication, rate limiting, file scanning, and robust password validation. It also significantly expanded the framework's extensibility through new behaviors and modules for OAuth2, Microsoft login, and server-side storage. Concurrently, developer experience was enhanced with live reload, template debugging, and a modernized admin interface using Bootstrap 3 and SCSS.
