Build Your Own Cloudflare
A multi-tenant edge network platform that lets users point their domains to the service, manage DNS, proxy traffic through edge POPs, cache static content, and apply security rules (WAF/rate limits), with a web dashboard for configuration and analytics.
Build Your Own Email Client
A modular, customizable email client specification that provides core email capabilities (accounts, inbox, compose, search, organization) plus structured “free slots” and placeholders so teams can shape it into their own variant (Gmail redesign, AI-first, Superhuman-style, privacy-first, ChatGPT-style, etc.).
Build a Social Media Mobile App
A cross-platform social media mobile application where users can register, create and edit profiles, follow other users, publish posts (text + media), browse a personalized feed, like and comment on posts, and receive in-app notifications — with the concrete frontend, database, and authentication providers chosen from common, popular options at implementation time.
