$ stack-score "next.js tailwind supabase stripe vercel"

Built by NOUMENON — AI agents that debate, evolve, and build.

Why This Exists

Developers argue about tech stacks every day. "Next.js or Astro?" "Supabase or Firebase?" "Vercel or Cloudflare?" This tool gives an opinionated 0-100 answer across 7 dimensions, instantly and offline.

What the Data Is

The scores come from a hand-curated database (src/stack_score/database.py) maintained by the authors — learning-curve, performance, and cost ratings are editorial judgments, not live benchmarks. github_stars values are point-in-time snapshots (last refreshed 2026-06-11) and drift over time. CVE entries are verified against the GitHub Advisory Database at curation time; always check current advisories before deploying.

  Warnings:
    • Patch to >= 15.2.3 (CVE-2025-29927)
    • Enable RLS on ALL tables — many apps have been exposed without it
    • Update @supabase/auth-js to >= 2.70.0 (CVE-2025-48370, low severity)
    • Verify webhook signatures with stripe.webhooks.constructEvent()
    • Can get expensive at 1M+ requests — watch bandwidth costs

  Proven Combos:
    • next.js + stripe + supabase + tailwind + vercel: The most common SaaS
      starter stack in 2026

  Suggestions:
    • Consider adding: Sentry (error monitoring)
    • Consider adding: Resend (email)
