Vigil is a microservices status page application written in Rust. It monitors distributed infrastructure services via multiple probe modes (HTTP, TCP, SSH, ICMP, push, script, local), aggregates their health status, and serves a public status page with real-time updates. It also sends alerts through various channels (Slack, Email, Twilio, Telegram, etc.) when services go down or recover. The architecture is a single binary with separate threads for probing, aggregation, and HTTP serving, using a shared in-memory state protected by RwLock. The codebase is well-structured, with clear separation of concerns: config reader, prober, notifier, aggregator, and responder modules. It includes an MCP server for AI agent integration. The project is actively maintained with recent commits and CI/CD pipelines.
CloudMeet is a full-stack meeting scheduler (Calendly alternative) built entirely on Cloudflare's free tier. It uses SvelteKit for the frontend and server-side logic, Cloudflare D1 for the database, KV for caching, and Workers for cron-based email reminders. The application supports single-user (admin) operation with Google Calendar and Outlook Calendar integration, allowing attendees to book meetings that automatically create calendar events with video conferencing links (Google Meet or Microsoft Teams). It includes a comprehensive email notification system via Emailit API, customizable availability rules, event types, and a dashboard for managing bookings, profiles, and email templates. The architecture is a monolith deployed to Cloudflare Pages with a separate cron worker for reminders. The codebase demonstrates solid engineering practices: TypeScript throughout, well-structured caching layer with KV and browser cache, request coalescing, input validation, and a modular email template system. It is not a data research project; it is a production-ready application.
