One pipeline. $0 / month.
AWSMindset is a personal field journal that publishes itself — almost. RSS feeds get drafted into Airtable by an LLM every morning, I review and approve, the site reflects the change within 60 seconds. The whole thing runs on free tiers.

The pipeline
From RSS to reader, in five stages
Tap any stage to see how it works.
Curated RSS feeds.
1. Sources
Ten engineering and AWS-focused feeds, ordered by editorial priority. AWS announcements and the AWS blog run first; Netflix, Uber, Meta, Pragmatic Engineer, React, web.dev, GitHub Blog, and Hacker News (filtered to 100+ points) fill the time budget.

Every layer of the stack lives within a generous free tier at this volume. The constraints push back well before the wallet does: Vercel Hobby caps at 1 cron/day, Gemini free tier at 15 RPM, Airtable at 1.2k records, Resend at 100 emails/day. If any of those become a ceiling, the cost is a small fraction of the alternative — Hobby → Pro is $20/mo, Airtable Pro is $20/mo, Resend Pro is $20/mo. Even at full upgrade, the bill stays under what a Cloudflare Workers Paid plan would cost.
