Where this came from (Reddit)

AI builders waste time comparing constantly changing model and GPU prices.

The threads (in our words)

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. The business below is our own design inspired by these threads.

Who it’s for

AI developers, startups and agencies watching costs.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. List providers with public pricing pages and check their terms.
  2. Schedule a daily agent run that reads prices and saves them in Supabase.
  3. Publish a free, searchable comparison table for SEO.
  4. Sell price-drop and price-change alerts through Stripe.
  5. Send a weekly “what changed” newsletter with beehiiv.
  6. Check flagged price changes before alerts go out.

Your autonomous stack

Autonomy: Agents gather sources, write the report and email it. Your part: Spot-check one report a week for accuracy (about 1 hour).

Every layer an agent-run business needs, in order. Prices are public list prices, checked Oct 16, 2026.

  1. Agent (the brain): Claude (incl. Claude Code) (opens in new tab) (Free tier · Pro $20/mo). Runs the business day to day: writes, answers, decides small things and reports to you. Grok Bot, Claude Code or Codex can also run scheduled jobs.
  2. Build and hosting: Vercel hosting (opens in new tab) (Hobby free · Pro $20/mo), Supabase database (opens in new tab) (Free tier · Pro from $25/mo), beehiiv newsletter (opens in new tab) (Free up to 2,500 subscribers). The product or service your customers use.
  3. Payments: Stripe payments (opens in new tab) (No monthly fee · 2.9% + 30¢ per card payment). Automatic checkout and receipts. Other options: PayPal Checkout (3.49% + 49¢) or Lemon Squeezy (5% + 50¢, handles sales tax).
  4. Customer acquisition: Buffer (scheduled X posts) (opens in new tab) (Free plan (3 channels, 10 queued posts each) · Essentials $5/mo per channel, billed yearly), beehiiv newsletter (opens in new tab) (Free up to 2,500 subscribers). Agent-written SEO pages, scheduled X posts and a weekly newsletter.
  5. Delivery: Make automations (opens in new tab) (Free tier · Core $16/mo). Automations deliver the product or result as soon as someone pays.
  6. Support: Make automations (opens in new tab) (Free tier · Core $16/mo). An AI inbox or chat answers questions; anything unclear is flagged for you.
  7. Monitoring and schedule: Make automations (opens in new tab) (Free tier · Core $16/mo). Scheduled runs (cron) each day: send, check for failures, alert you if something breaks.
  8. Analytics: Google Analytics (opens in new tab) (Free). Tracks visits, signups and sales so the agent can report what works.
  9. Human checkpoint: Spot-check one report a week for accuracy (about 1 hour).
  10. Price: charge $9 per subscriber (monthly alerts plan). Offer the first 3 customers a founding price for honest feedback.
Monthly cost$0–$86/monthFree tiers → paid plans of the tools above. Card fees come out of each sale.
What you could earn · EstimateEstimate: 80 subscribers × $9 = $720/moOur estimate, not a fact or a promise. It’s simple math if you land these customers at this price.

What they did

Agents check AI API and GPU rental prices daily; builders get a free table and pay for alerts. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.
