Introduction to Lovable with InitRepo
Lovable.dev is one of the most capable AI app builders available. Give it a prompt and it generates a full React + Supabase application — authentication, database schema, UI, and all — that you can deploy with a single click. For founders, indie hackers, and developers who want to ship fast, it's genuinely transformative.
The problem isn't Lovable's ability to generate code. The problem is that most people come to Lovable with a vague idea and start typing. Lovable makes assumptions, generates something plausible-looking, and then the real work begins: endless rounds of "change this", "add that", "actually make the sidebar work differently" — each iteration drifting further from a coherent product.
InitRepo solves this by giving you the structured planning documents that Lovable's AI needs to make consistently good decisions. A 15-minute planning session with InitRepo produces a Project Brief, PRD, User Stories, and Architecture Spec that you can paste directly into Lovable as context — and watch it build exactly what you had in mind.
What Lovable Is Optimized For
- • React + Supabase full-stack apps — auth, database, and UI in one shot
- • Rapid prototyping — working app in minutes, not days
- • MVPs and side projects — get something in front of users fast
- • UI-heavy products — dashboards, SaaS tools, internal apps
What InitRepo Adds to the Stack
- • Project Brief — scope, audience, and goals that anchor every Lovable session
- • PRD — feature requirements specific enough for Lovable to implement correctly
- • Architecture Spec — database schema, auth setup, and API patterns to follow
- • User Stories — feature-by-feature session guides that keep Lovable focused
- • UX/UI Spec — design direction for consistent visual output
The Vibe Coding Wall
"Vibe coding" — writing prompts and iterating until the app looks right — works brilliantly for simple projects. A landing page, a basic CRUD tool, a quick prototype to show investors. But almost every builder hits the same wall when the product grows beyond a few screens.
Signs You've Hit the Wall
- • You've regenerated the dashboard three times and it still doesn't feel right
- • Lovable adds a feature in one place and breaks it somewhere else
- • The database schema makes sense for screen 1 but not screen 5
- • You can't remember what you decided about user permissions last Tuesday
- • Each session starts with re-explaining the same context
- • The app looks great but the data model is a mess
- • Adding a new feature means re-doing work from a previous session
- • You're not sure what "done" looks like for the MVP
These aren't Lovable bugs — they're planning gaps. Lovable is an expert builder, but like any expert builder, it needs blueprints. Without blueprints, every session starts from scratch and every decision is made ad hoc.
The Real Cost of Unplanned Lovable Sessions
How InitRepo Unlocks Lovable's Full Potential
InitRepo generates six structured planning documents from a 10-minute questionnaire. Each document plays a specific role in making your Lovable sessions more focused, more productive, and less likely to require rework.
📋 Project Brief → Lovable's First Prompt
The Project Brief defines what you're building, who it's for, and what the MVP includes and excludes. Paste it as the first message in a new Lovable session and Lovable starts with the full picture — no assumptions, no scope creep.
📄 PRD → Feature Session Context
Before each feature session, paste the relevant PRD section. Lovable knows exactly what the feature should do, what edge cases to handle, and how it connects to other features.
🏗️ Architecture Spec → Consistent Technical Decisions
The Architecture Spec tells Lovable which Supabase tables to create, which auth approach to use, and what patterns to follow. This prevents the common problem of Lovable making conflicting technical choices across sessions.
📝 User Stories → Focused Sprint Sessions
Each user story is a focused Lovable session. "As an admin, I want to manage user permissions so that I can control who sees what." One story, one session, clear acceptance criteria.
Setting Up Your Lovable Workflow
The setup takes about 30 minutes total. Once you have your InitRepo documents, every Lovable session is focused and purposeful.
Run InitRepo (10–15 minutes)
Answer the wizard questionnaire about your project. Be specific about your target user, core workflow, and what the MVP includes. InitRepo generates all six planning documents immediately.
Download and organise your documents
Download the ZIP from your InitRepo dashboard. Open the Project Brief, PRD, Architecture Spec, and User Stories in your editor. You'll reference these throughout your Lovable build.
Open a new Lovable project
Start a new project in Lovable. Before writing your first prompt, paste in your Project Brief and Architecture Spec. This sets the foundation for everything Lovable will generate.
Build feature by feature using User Stories
Work through your user stories in priority order. Each story is one focused Lovable session. Paste the story and its acceptance criteria, then let Lovable implement it before moving to the next.
Step-by-Step: Brief to Built App
Here's a concrete walkthrough using a SaaS project management tool as the example.
Phase 1: Foundation (Session 1)
Open Lovable and paste your Project Brief plus the database schema from your Architecture Spec. Ask Lovable to generate the app skeleton: Supabase schema, authentication, and the main navigation structure — nothing more.
Example first prompt:
"Build the foundation for this app using the Project Brief and Architecture Spec below. Create the Supabase schema exactly as specified, set up email magic link auth via Supabase, and generate the navigation shell with placeholder screens. Don't build any features yet — just the skeleton. [paste documents]"
Phase 2: Core Feature (Sessions 2–4)
Work through the core user stories one at a time. For each, paste the story and its acceptance criteria. Review the output against the criteria before moving on. If something's off, paste the specific criterion that failed and ask Lovable to fix it.
Example story session prompt:
"Implement this user story: As a project owner, I want to create a project with a name, description, and team members, so that I can organise work with my team. Acceptance criteria: [paste]. Use the existing Supabase schema — don't add new tables."
Phase 3: Polish and Edge Cases (Sessions 5–6)
With core features working, use the PRD to drive polish. Empty states, error states, loading states, mobile responsiveness. Paste the UX/UI Spec for design direction. The PRD's non-functional requirements section is useful here for performance and accessibility.
Example polish prompt:
"Go through every screen and add: proper loading states, empty states with a clear first action, and error states that explain what went wrong. Follow the UI style from this spec: [paste UX/UI Spec design section]."
Sprint-Based Feature Development
Once you've shipped your MVP, use your InitRepo documents to plan feature sprints. The User Stories document already has your backlog — work through it systematically rather than reactively.
Keeping Lovable on Track
- • Start every new session with: "Here's what we've built so far and what we're adding today" — paste the relevant sections
- • After any large change, paste your Architecture Spec and ask Lovable to verify it hasn't drifted from the schema
- • Use the PRD's "Out of scope (v1)" section explicitly to stop Lovable from adding features you don't want
When to Regenerate vs. Iterate
- • Iterate when a specific feature isn't right — paste the acceptance criteria and ask for a fix
- • Regenerate a section when the data model for a feature is wrong — reference the Architecture Spec
- • Start a new session when context gets muddled — begin with the relevant document sections fresh
GitHub Sync Workflow
Lovable supports GitHub sync. Once your project is connected:
- • Store your InitRepo documents in the repo under
/docs/planning/ - • Each Lovable session corresponds to a meaningful commit — reference the User Story ID in the message
- • If you need to hand off to a human developer, the planning documents are already in the repo
Key Benefits and Time Savings
Consistent database schema across all sessions
The Architecture Spec prevents Lovable from inventing new tables or breaking the existing schema when adding features.
Scope stays controlled
The PRD's in-scope and out-of-scope lists give you something concrete to reference when Lovable starts suggesting features you didn't ask for.
Ready to hand off to developers
If your product grows beyond what Lovable handles alone, the planning documents give any human developer the full context they need to take over.
Clearer user research and feedback loops
When you know exactly what you built (the User Stories define it), you know exactly what to test with users and what feedback is in-scope to act on.
Real-World Use Cases
🚀 Founder Shipping a SaaS MVP
A first-time founder has a SaaS idea but no engineering background. They use InitRepo to plan the product in 15 minutes, then spend a day in Lovable building the MVP feature-by-feature using user stories as a guide. The result: a working, deployed product ready for first users — without writing a line of code.
💡 Developer Prototyping a Client Idea
A freelance developer uses InitRepo to turn a client's vague idea into a structured plan, then uses Lovable to build a clickable prototype in an afternoon. The client sees a real working demo — not a slide deck. The InitRepo documents become the basis of the formal project scope when they decide to build for real.
🛠️ Internal Tool Builder
A product manager needs an internal tool for their team — something ops has been requesting for months but engineering never has time to build. They use InitRepo to plan it properly, then build it in Lovable. Because they have an Architecture Spec, the Supabase schema matches what the ops team actually needs, not what seemed obvious in the moment.
Best Practices for Maximum Results
✅ Do This
- • Start every Lovable project by pasting the Project Brief and Architecture Spec
- • Use one user story per session — don't try to build multiple features at once
- • Paste acceptance criteria explicitly and ask Lovable to verify them before moving on
- • Keep the PRD open next to Lovable as a running reference
- • When Lovable suggests a feature you didn't plan, check the PRD's out-of-scope list first
- • After major changes, paste the Architecture Spec and ask for a schema consistency check
❌ Avoid This
- • Vague prompts like "make it look better" without pasting the UX/UI Spec
- • Building features that aren't in your user stories yet
- • Letting Lovable create new Supabase tables without referencing the Architecture Spec
- • Skipping the foundation session — auth and schema mistakes are expensive to fix later
- • Using Lovable to make big architectural changes mid-build without re-pasting the spec
- • Starting a feature session without pasting the relevant PRD section first
Common Challenges and Solutions
🚨 Issue: Lovable keeps changing the database schema
You ask Lovable to add a feature and it creates new Supabase tables that conflict with what you already have.
💡 Solution:
- • Start every session with: "Here is our current Supabase schema — do not deviate from it: [paste Architecture Spec database section]"
- • If the feature genuinely requires a schema change, update your Architecture Spec first, then paste the updated version
- • Use Lovable's "don't change existing tables" instruction for sessions that only modify UI
🚨 Issue: The UI looks inconsistent across screens
Different screens use different component styles, colors, or spacing — the app doesn't look cohesive.
💡 Solution:
- • Paste the UX/UI Spec's design system section at the start of any session that adds new screens
- • Ask Lovable for a "consistency pass" — paste all screen names and the design spec, ask it to unify them
- • Define a component library early and reference it explicitly when adding new features
🚨 Issue: Scope keeps expanding
You started with a simple MVP idea but the app is growing with features you didn't plan and don't need yet.
💡 Solution:
- • Paste the PRD's "Out of scope (v1)" section at the start of each session as a guardrail
- • When Lovable suggests something not in your user stories, explicitly decline: "That's not in scope for v1, skip it"
- • Add any good ideas to your PRD's backlog section — they're not lost, just not now
Ship Your MVP This Week
Lovable is extraordinary at building — but like any skilled builder, it needs a blueprint to build the right thing. InitRepo provides that blueprint in 15 minutes, and the combination turns "I have an idea" into "I have a working app" in a single day.
