The stack under every project
Not plugins, not preferences — engineering decisions baked into every site we build.

- Static-first output for maximum performance
- Edge delivery out of the box
- Structured content architecture
- Powers every Foundation and Modernization project
SparkEngine
The performance and growth infrastructure layer.
SparkEngine handles everything that makes a site fast, visible, and measurable — Core Web Vitals optimization, structured data, sitemap generation, and ongoing performance monitoring.
