Slack-alike is a real-time guest chat app with multiple rooms, live messaging, presence, typing indicators, and room creation. Usage note: Best tested with two different browsers to verify real-time messaging, presence, and typing indicators.
News-mailer is a full-stack newsletter manager for creating newsletters, managing subscribers, building signup forms, segmenting audiences, writing campaigns, and reviewing delivery activity. Includes a no-login demo mode with seeded localStorage data. Usage note: Demo and real app share the same UI patterns, but demo mode uses localStorage and never calls Supabase or Resend.
