Show HN: I built a free AI tool that picks your SaaS tech stack based on budget

Hey HN,

  I kept seeing the same question asked over and over in startup communities:
  "What tech stack should I use for my SaaS?" The answers were always
  scattered, opinionated, and never accounted for budget or team size.

  So I built appstackbuilder.com — you tell it your monthly budget, app type,
  team size, and skill level, and it recommends a full stack (auth, database,
  hosting, payments, analytics, etc.) with actual pricing for each tool.

  A few things that make it different from generic advice:

  - It accounts for team size when calculating costs (e.g. Clerk charges per
    user, Linear charges per seat — most stack guides ignore this)
  - You can toggle "no-code only" if you're a non-technical founder
  - It shows you 2–3 alternatives per category, not just one option
  - You can export the full stack as a PDF or share a link
  - It's completely free, no account required

  Under the hood: Next.js, Supabase, and Gemini for the recommendations.
  The tool database has ~80+ tools across categories with real pricing data
  I manually verified.

  What I'm still figuring out:
  - How to keep pricing data fresh as tools change plans frequently
  - Whether to add a "stack score" based on community usage data
  - If the no-code recommendations are actually good (I'm a developer,
    so I'd love feedback from non-technical founders specifically)

  Would love brutal feedback, especially if the recommendations feel off
  for your use case.
