SIDE-BY-SIDE CODE SAMPLES

Bolt

.bolt/prompt

text

You are building a SaaS dashboard application.

Stack: Remix with TypeScript, Prisma ORM, PostgreSQL, TailwindCSS.

Key rules:
- Use server loaders for data fetching, not client-side fetch
- All forms use Remix Form with progressive enhancement
- Use Prisma for all database operations
- Style with TailwindCSS utility classes, no custom CSS
- Components go in app/components/, routes in app/routes/
- Use zod for form validation on both client and server

Lovable

AGENTS.md

markdown

# Project Instructions

## Stack
- React 19 with TypeScript
- Supabase for backend (auth, database, storage)
- TailwindCSS v4 + shadcn/ui components
- Vite for building

## Architecture
- Feature-based folder structure
- Each feature owns its components, hooks, and types
- Shared components in src/components/ui/
- All API calls go through src/lib/supabase.ts

## Conventions
- Use shadcn/ui components before creating custom ones
- Mobile-first responsive design
- Use Supabase RLS policies for authorization
- Prefer server-side filtering over client-side

## Brand
- Primary color: #6366F1 (indigo)
- Font: Inter for body, Cal Sans for headings
- Rounded corners (radius-lg) on all cards

1. Config format

Bolt: text. Lovable: markdown.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Bolt, configure .bolt/prompt. If you use Lovable, configure AGENTS.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
