Lovable?

NOT REALLYA prototype of the interface is possible, but the durable product depends on difficult systems beyond the UI. Build a safer adjacent workflow instead.

BUILD FIRST

A non-sensitive or read-only version of the core experience
A manual review step wherever correctness or trust matters
A narrow companion tool that removes a real piece of work

LEAVE FOR LATER

Regulated decisions, payments, or irreversible actions
Claims of correctness, compliance, or uptime that the MVP cannot support
Sensitive integrations until security, support, and auditability are ready

Lovable is a full-stack AI development platform that generates production-grade web applications from natural-language prompts. Users describe an app or paste screenshots/docs; Lovable writes code, designs UI, and assembles a working app in real time, which users refine via follow-up prompts and visual layout/color/text edits. It produces editable code on an industry-standard stack: React, Tailwind, and Supabase, with auto-provisioned PostgreSQL, authentication, file storage, and real-time features. Projects sync to GitHub from day one. One-click publishing handles custom domains, SEO, and security scans. It supports the full lifecycle: prototyping, iteration, deployment, and ongoing operation. Enterprise features include shared workspaces, roles/permissions, credits pooling, 2FA, SSO, SCIM provisioning, data usage controls, and security checks. An optional built-in AI connector adds cha

RESEARCHED BUILD PROMPT

Give this to your coding agent.

Build an open-source web app called 'PromptStack' — a natural-language full-stack app generator inspired by Lovable's workflow. The core flow: a user types a description of a web app (or pastes a Notion doc / drops a screenshot) into a chat panel; the system streams back a working scaffold — frontend, database schema, auth — and lets the user iterate with follow-up prompts and direct visual tweaks before deploying. Requirements: (1) Chat UI that streams generated code and shows a live preview pane that updates as code is written; (2) scaffolding engine that emits a React (Vite) + Tailwind frontend and a Supabase backend with default tables for user profiles and app-specific models inferred from the prompt; (3) follow-up prompts that modify existing generated files rather than regenerating from scratch; (4) visual edit mode for layout, colors, and text that writes changes back to the codebase; (5) one-click 'deploy' that pushes to a target (Netlify/Vercel) and returns a public URL; (6) optional GitHub sync that creates a repo and commits each iteration. Technical approach: use an LLM API (e.g., OpenAI or Claude) with a system prompt tailored to generating project files, maintain a virtual file tree in a backend store (SQLite or Postgres), run the preview via an iframe pointing to a sandboxed builder server, and use a Vite dev server in the backend to hot-reload previews. Do NOT copy Lovable's brand, logo, marketing copy, color scheme, or UI layout — this is a clean-room replacement with a distinct name and neutral design. Out of scope for v1: multi-user workspaces, team credits/billing, SSO/SCIM/2FA, n8n integration hub, built-in AI feature connectors (chatbots/RAG/etc.), mobile apps, and enterprise security audit tooling. Deliver a README covering local setup (env vars for LLM API key, Supabase URL, GitHub token), how generation and iteration work, deploy steps, and important limitations (e.g., token limits, no migration for existing DBs, preview sandboxing caveats, LLM nondeterminism).
