Tool review
Arcjet
Application security toolkit for rate limiting, bot detection, signup protection, WAF-style filters, email validation, and AI prompt protection. A practical abuse-prevention layer for small teams shipping public apps quickly.

Auth.js
Open-source authentication toolkit formerly known as NextAuth.js, now maintained under the Better Auth umbrella. Worth considering when you want more direct control over auth wiring and are comfortable owning the implementation details.
Comparison
Lovable vs Antigravity for Vibe Coders
These both sit in the “build with AI” bucket, but they solve different first problems. Lovable is the faster path from idea to deployed web app. Antigravity is stronger when you want agents operating inside real repos with more verification, control, and orchestration.
Comparison
Supabase vs Firebase for Vibe Coders
These are two of the fastest ways to bolt a real backend onto an AI-built app, but they optimize for different futures. Supabase is usually the cleaner default for SQL-first web apps. Firebase is still brutally effective when mobile support, post-launch tooling, and the wider Google app ecosystem matter most—and it now has a real Postgres path through SQL Connect.
