Modern web stack

As of September 3, 2026, TopK's stack: The live site runs on AWS and Cloudflare with Datadog for observability and Next.js on the front end, plus five additional detected technologies; the AWS and Cloudflare pairing is consistent with the object-storage, global-edge architecture the homepage describes.
