The premise
SaaS automation tooling gets expensive fast. This architecture breakdown shows how I built a full internal productivity suite — AI content generation, task queues, real-time updates — for exactly $0/month: Google Colab as free compute, Supabase's free tier as the database and real-time layer, and lightweight Chrome extensions as the client.
The result
The stack processed over 5,000 automated tasks in its first month while saving roughly $300/month in subscriptions. The full architecture — how the pieces connect and where the sharp edges are — is in the breakdown.
