Turn a rough idea into a Build Pack Lovable can ship.
Detailed, structured build prompts covering schema, RLS, auth, validation, error states, empty states and edge cases — so Lovable builds it right the first time and you burn fewer credits getting to a production-ready app.

The USP
What's in a Build Pack
Not a wall of text. A structured spec that thinks through the parts of your app most prompts skip — the parts that cause rebuilds.
Explicit sections for data model, auth, UI, edge cases, error and empty states, and acceptance criteria — so Lovable knows exactly what to build.
- Per-feature acceptance criteria
- Empty, loading and error states
- Mobile and responsive checks
The critique enforces the patterns real production apps need — the things that turn a slick demo into something you can actually ship.
- Supabase RLS on every user table
- Role tables, not role columns
- Server-side validation & safe redirects
The Build Pack drops straight into Lovable. Pro plans also generate a paste-ready Supabase migration with RLS policies, so the database is wired up on build one.
- Lovable-ready build prompt
- Supabase migration SQL (Pro)
- Versioned iterations with rollback
Completeness, not just vibes.
Every Build Pack is graded against a completeness checklist: schema present, RLS policies specified, error & empty states defined, acceptance criteria per feature. Miss any and the critique flags it before you paste into Lovable.
Save credits. Ship sooner.
Every Lovable rebuild costs credits. A better prompt is the cheapest optimisation you can make.
How it works
Three steps between a half-formed idea and a Build Pack that holds up in production.
Raw idea vs Build Pack
What Lovable actually receives — and what it does with it.
- Vague prompt — Lovable guesses the data model
- No RLS specified — user data leaks between accounts
- No error or empty states — UI breaks the first time a query fails
- Auth flow underspecified — password reset and verify get patched later
- Multiple rebuild cycles, credits burned chasing the same bugs
- Structured spec with data model, auth, UI, edge cases
- RLS policies specified per table — user data stays isolated
- Error, empty and loading states defined for every screen
- Auth flows fully described: sign in, verify, reset, delete
- Builds cleanly on the first try — credits preserved
Every Build Pack includes SEO scaffolding by default: per-route titles and meta descriptions, canonical tags, Open Graph, JSON-LD, a real sitemap.xml and an AI-crawler-aware robots.txt. Content-led packs can add an optional edge prerender Worker for GPTBot, PerplexityBot and ClaudeBot.
It's not the headline feature — it's just something we refuse to ship without. Your app is findable on day one, no extra work.
Built for vibe-coders
Versioned iterations
Every applied rewrite creates a new version. Try aggressive changes without fear and roll back instantly if something goes sideways.
