Vely
Vely is a general-purpose framework for rapid development of high-performance software. It is especially well suited for web applications. It's Free Open Source (under the business-friendly Eclipse Public License 2 (EPL-2)).
Vely is declarative and functional, with single-line statements performing entire tasks. It's simple to design, write and maintain applications.
Decades of adding energy-intensive abstractions on top of programming languages led to increase in complexity and decrease in performance. Vely applications are 100% native, high-performance and low-footprint without interpreters, virtual machines, or byte-code schemes.
