Engineering and product notes from FlareStarter.
Drizzle vs Prisma — the comparison changes completely on Cloudflare D1
On Postgres this is a taste argument. On D1 it is not — Prisma's D1 support is Preview and silently drops transaction semantics, while D1 itself does have transactional batches. Verified against both vendors' docs.
Cloudflare D1 vs Supabase — a comparison that is usually a category error
Supabase is a backend platform built on Postgres. D1 is a SQLite database bound to your Worker. Comparing them head-to-head is wrong, and the right comparison is more useful. With real August 2026 pricing.
better-auth vs Clerk — what you are really buying at $125/month
Clerk's B2B organizations are a $100/month add-on on top of the $25 Pro plan. better-auth's organization plugin is free and runs in your own database. Here is what that price difference actually buys, and when it is worth paying.
TanStack Start vs Next.js — picking the one that is not 1.0 yet
Next.js is the safe default and will stay that way. Here is the honest case for TanStack Start anyway, from a team running it in production on Cloudflare Workers while it is still a release candidate.
Stripe vs Polar — the fee comparison misses the actual decision
Polar is a merchant of record, Stripe is not. That single difference decides who owes sales tax in twenty jurisdictions — and it matters more than the percentage on the pricing page. With real August 2026 numbers.
Cloudflare Workers vs Vercel — what a real SaaS actually costs on each
A side-by-side of Cloudflare Workers and Vercel using each platform's published August 2026 pricing, plus the architectural differences that decide the bill — seats, the database you have to bring, and where SSO stops being free.

Idempotent Stripe webhooks on Cloudflare Workers
