PeakStack Guides

Ship AI-built software without shipping the risk

Direct, practical guides to the security, scalability, and cost gaps in AI-generated code, whether you vibe-coded it or built it with an agent, grouped by the tool you used and the stack you run on.

AI builders & agents

Vibe-coded with a builder (Lovable, v0, Bolt) or agentic-coded with an agent (Cursor, Codex, Antigravity, Claude Code)? Both face the same risks. Start here for what to harden before real users arrive.

Is Lovable code production-ready? What to check before you launch

Lovable ships a working app fast - but speed hides risk. The security, scalability, and cost gaps to fix in Lovable-generated code before real users arrive.

AI builder · Security

v0 app security checklist: hardening Vercel v0 output before launch

v0 generates polished UI and full-stack scaffolding fast. The security checks - auth, server actions, secrets, access control - to run before v0 code goes live.

Bolt.new production readiness: from working prototype to safe launch

Bolt.new gets you a running app fast. The security, scalability, and cost checks that turn a Bolt prototype into something safe to launch to real users.

Reviewing Cursor-generated code: a practical pre-merge checklist

Cursor writes code fast across your whole repo. The security, scalability, and correctness review steps to run on AI-generated changes before you merge them.

Replit Agent security checklist: what to harden before going live

Replit Agent builds and deploys a full app autonomously. The security, access-control, and cost checks to run before a Replit-built app faces real users.

Reviewing OpenAI Codex output: a pre-merge checklist for agentic code

Codex writes and edits code autonomously across your repo. The security, scalability, and cost review to run on agentic code before you merge it.

AI agent · Production readiness

Shipping Antigravity-built apps: an agentic production-readiness checklist

Antigravity builds and edits apps agentically. The security, scalability, and cost checks to run before an agent-built app faces real users.

AI agent · Security

Claude Code security checklist: hardening agentic changes before they ship

Claude Code edits your repo and runs commands agentically. The access-control, secret, and dependency checks to run before agentic changes ship.

AI code · Security

Is AI-generated code secure? What the research says, and how to check

Studies find roughly 45% of AI-generated code ships with a security weakness. Why it happens, the most common vulnerability classes, and how to check your own app.

Stacks & frameworks

Stack-specific reviews: the mistakes AI-generated code tends to make on the platforms you ship on.

Stack · Security

Common Firebase security mistakes in AI-generated apps

AI builders lean on Firebase and ship permissive rules by default. The Firestore, Auth, and Storage security mistakes to fix before your AI-built app goes live.

Stack · Production readiness

Next.js production readiness checklist for AI-built apps

A Next.js production readiness checklist for AI-generated apps: server actions, auth boundaries, secrets, caching, and the scalability and cost checks before launch.

Stack · Security

Supabase security checklist for AI-generated apps

AI builders love Supabase but often ship without Row Level Security. The RLS, policy, key, and storage checks to run before a Supabase app goes live.

Stack · Security

Stripe integration security in AI-built apps

AI-generated Stripe code often skips webhook signature verification and trusts client-set amounts. The payment-security mistakes to fix before you take real money.

Stack · Scalability

Postgres scalability mistakes in AI-generated apps

The Postgres patterns AI-generated code gets wrong - N+1 queries, missing indexes, unbounded reads - and how to fix them before they slow your app to a crawl.

Stop reading checklists. Run them automatically.
