The Solo Founder's Lean Stack: Bubble + n8n + Supabase Setup Guide (2025)
Building a startup alone in 2025 looks dramatically different than it did just a few years ago. You're competing against well-funded teams while wearing every hat yourself. The good news? Solo-led exits now account for 52.3% of successful startup outcomes, proving that going it alone isn't just viable, it's increasingly the norm.
The secret weapon? A lean tech stack that maximizes velocity while minimizing complexity and cost. Enter the Bubble + n8n + Supabase combination: a powerful trio that lets you build, automate, and scale your MVP without writing extensive code or assembling a technical team.
This isn't about taking shortcuts. It's about strategic tool selection that allows you to focus on what matters most: validating your idea with real users and iterating based on their feedback. As the Lean Startup methodology emphasizes, the unit of progress for startups is validated learning, not features shipped.
Traditional MVP development can cost $35,000 to $150,000 and take three to six months, according toindustry estimates. This stack flips that equation entirely, getting you to market in weeks for under $100/month. Whether you're building a SaaS product, marketplace, or internal tool, you'll have a clear roadmap for bringing your idea to life - solo.

Why This Stack Works for Solo Founders
The bar for what constitutes a "minimum" viable product has risen substantially. Users expect polished experiences even from early-stage products. As one analysis notes, "the floor for viability in 2025 includes what would have been considered premium features in 2015." This stack lets you deliver that quality without the traditional development timeline.
Speed Meets Professional Quality
Where a custom-coded MVP might take months, this stack can get you to launch in weeks. Bubble handles your visual interface with a drag-and-drop editor that makes traditional frontend development look glacial. Supabase provides instant backend infrastructure, database, authentication, and APIs that would typically require extensive setup. And n8n automates the connections between everything, eliminating custom integration code that often becomes a maintenance nightmare.
The speed advantage isn't just about faster building. It's about faster learning. Every week you're not in the market is a week you're not gathering real user feedback. With AI startups now reaching $1 million in annual revenue four months faster than traditional SaaS, velocity matters more than ever.
The No-Code Advantage Without Limitations
Critics of no-code platforms often point to their limitations. This stack addresses those concerns head-on. Bubble isn't just a simple website builder, it's a full-fledged development platform with an API connector that integrates with virtually any external service. When you hit the edges of what Bubble can do natively, Supabase and n8n step in.
Supabase gives you the power of PostgreSQL, one of the most robust relational databases available, with the ease of a managed service. Need complex queries or custom database functions? You've got full SQL at your disposal. And n8n's flexibility means you can write custom JavaScript or Python code when needed, while handling 90% of your automation needs visually.
This combination gives you an escape hatch from typical no-code limitations while maintaining speed advantages. You're building on open standards and technologies that scale with your business, not locked into a proprietary system.

The Three Pillars Explained
Before diving into setup, let's understand what each tool brings and why this particular combination works so well together.
Bubble: Your No-Code Frontend
Bubble is a visual programming platform that lets you design, develop, and deploy web applications without writing code. Since its founding in 2012, it has evolved to support complex workflows, advanced database management, and thousands of third-party integrations. Companies have built everything from simple landing pages to full-featured SaaS platforms serving thousands of users.
The drag-and-drop interface means you can see changes in real-time, dramatically speeding up the design-to-development cycle. Want to test a new user flow? Build it in minutes. Need to pivot based on user feedback? Make changes live without waiting for deployment cycles. The platform also handles hosting and deployment, abstracting away server management complexities.
Supabase: Your Backend Infrastructure
Supabase markets itself as the open-source Firebase alternative, but it's more accurately a complete backend-as-a-service platform built on PostgreSQL. You get enterprise-grade database technology without enterprise complexity or cost.
At its core, Supabase provides a PostgreSQL database wrapped in developer-friendly tools: instant APIs, real-time subscriptions, authentication, file storage, and edge functions. The authentication system alone saves countless development hours, supporting email/password, magic links, OAuth providers, and phone authentication with minimal configuration.
The platform's generous free tier includes 500MB of database storage, 1GB of file storage, and 50,000 monthly active users, plenty for MVP validation and initial traction. What makes Supabase particularly valuable is its seamless integration with both Bubble and n8n, serving as the central source of truth for your data.
n8n: The Automation Powerhouse
If Bubble is your frontend and Supabase is your backend, n8n is the intelligent middleware connecting everything. It's workflow automation on steroids—providing the flexibility of code with the speed of visual programming.
N8n stands out because of its open-source nature and developer-friendly approach. Unlike tools that lock you into their ecosystem, n8n can be self-hosted, giving you complete control over your data and workflows. With over 400 pre-configured integrations and the ability to make HTTP requests to any API, you're not limited by what the platform supports out of the box.
The platform recently raised $180 million in Series C funding at a $2.5 billion valuation, signaling strong market validation and long-term viability. For solo founders, n8n becomes your virtual technical team member, handling repetitive tasks and ensuring data flows smoothly between your tools.
How They Work Together
Here's the magic: in this architecture, Bubble serves as your user-facing layer, Supabase becomes your single source of truth for data, and n8n orchestrates the workflows that tie everything together.
When a user signs up through your Bubble interface, Bubble creates the account through Supabase's authentication API. This triggers an n8n workflow that:
Sends a welcome email through your email service
Creates a profile entry in Supabase with default settings
Adds the user to your CRM
Notifies your team in Slack
Schedules follow-up tasks
Each tool handles what it does best. Bubble provides a smooth user experience. Supabase maintains data integrity. N8n orchestrates complex workflows. This separation of concerns keeps your architecture clean and maintainable as you scale.

Setting Up Your Lean Stack
Ready to build? This guide walks you through setting up each component and connecting them into a cohesive system.
Phase 1: Supabase Foundation (30 minutes)
Start with Supabase because it forms the foundation. Head to Supabase and create a free account. Click "New Project," name it, choose a strong password, and select a region close to your users.
Navigate to Project Settings > API and save these credentials:
Project URL: Your API endpoint
Anon public key: For client-side requests
Service role key: For backend operations
Click "Table Editor" and create tables for your core data. Supabase automatically creates an API for any table you build. Navigate to Authentication > Providers and enable email plus one social login (Google works well). Supabase handles all OAuth flows automatically. Finally, enable row-level security on your tables and create policies defining who can access what data.
Phase 2: Bubble Interface (2-3 hours)
Visit Bubble.io and create your app. Navigate to Plugins > Add Plugins and install the "API Connector." Configure it with your Supabase URL and create API calls pointing to Supabase's REST API endpoints. Include your Supabase API key in the headers.
Build your essential pages: landing page, signup/login forms, and main application interface. Focus on usability over elaborate visuals—your goal is validating your concept, not pixel-perfect design. Use the workflow editor to define what happens when users interact with elements. Set up workflows that send form data to your Supabase API calls, keeping them straightforward for your MVP.
Phase 3: n8n Automation (1-2 hours)
Use n8n Cloud for the easiest setup (free tier available). Create your first workflow and add a Supabase node, entering your credentials (URL and service_role key). Test by reading from one of your tables.
ForBubble integration, generate an API key in Bubble (Settings > API) and configure an HTTP Request node in n8n. Build your first automation: a workflow with a webhook trigger, Supabase node to fetch new users, and email node to send welcome messages. Then create synchronization workflows that sync users to your CRM, update analytics, back up data to Google Sheets, and post Slack notifications when key metrics are hit.

Real-World Implementation
Understanding how others have used this stack can spark ideas for your MVP.
SaaS Product with Subscription Management
A solo founder building a project management tool used this exact stack. Bubble powered the interface, Supabase stored projects and tasks, and n8n handled subscription management. When users signed up for paid plans, n8n:
Integrated with Stripe for payment processing
Updated user permissions in Supabase
Sent onboarding emails
Scheduled trial expiration reminders
The automation meant the founder could focus on product development without manually managing subscriptions. As the user base grew, the system scaled automatically.
AI-Powered Customer Support
A more technical founder leveraged this stack to build a support tool with AI capabilities. Bubble handled the ticket interface, Supabase stored conversations using its vector database features, and n8n orchestrated AI workflows by:
Sending customer queries to OpenAI
Retrieving relevant context from Supabase vector store
Generating suggested responses
Learning from feedback to improve over time
This RAG (Retrieval-Augmented Generation) system gave the solo founder enterprise-level AI capabilities without hiring a machine learning team.
Content Marketplace Platform
Another founder created a marketplace connecting creators with buyers. Bubble powered both interfaces, Supabase stored user profiles and listings, while n8n managed complex workflows. When creators uploaded content, n8n:
Checked quality standards
Generated thumbnails automatically
Sent for moderation review
Notified creators of approval status
When buyers purchased, n8n handled payment processing, transferred funds to creators (handling platform fees), sent purchase confirmations, generated invoices, and updated analytics dashboards. This level of automation would typically require a development team, butn8n's workflow capabilities made it manageable for one person.

Cost Breakdown: Budget Reality
Understanding true costs helps you budget appropriately and avoid surprises as you scale.
MVP Stage (0-100 Users)
When launching and validating your concept, costs remain minimal:
Bubble:
Free plan for development and testing
Upgrade to Starter ($29/month) only when deploying on a custom domain
Supabase:
Free tier includes:
500MB database storage
1GB file storage
50,000 monthly active users
2GB bandwidth
Authentication and real-time features
n8n:
Self-hosted community edition: $0 (plus ~$10/month hosting)
n8n Cloud free tier: 5,000 workflow executions/month

As your user base grows:
Bubble Growth Plan: $119/month
Premium version control
Increased capacity
Professional features
Supabase Pro: $25/month
8GB database storage
100GB file storage
250GB bandwidth
Daily backups and point-in-time recovery
n8n Cloud: ~$50/month
20,000 workflow executions
Priced per execution vs. per operation, making it significantly cheaper than alternatives like Zapier ($500+ for equivalent functionality)
Total growth stage cost: $194-225/month
Scale Stage (10,000+ Users)
At meaningful scale with revenue:
Bubble Team Plan: $349/month
Collaboration features
Advanced security
Higher capacity
Supabase Team: $599/month
Organization-level features
Professional support and SLAs
n8n: Scale through self-hosting or enterprise tiers
Total scale stage cost: $948+/month
Even at scale, this remains dramatically less than hiring a technical team ($5,000-15,000/month) or managing custom infrastructure. You're essentially getting a virtual technical team for less than one junior developer's salary.
Additional Considerations
Budget for supporting services:
Email delivery (SendGrid/Postmark): $10-50/month
Payment processing (Stripe): 2.9% + $0.30 per transaction
File storage overages if media-heavy
API costs for third-party integrations
Compared to traditional development approaches, this stack delivers extraordinary value at every stage.
Cost Breakdown: Budget Reality
Understanding true costs helps you budget appropriately and avoid surprises as you scale.

Conclusion
Building a startup as a solo founder in 2025 is more viable than ever. The Bubble + n8n + Supabase stack represents the sweet spot between ease of use, power, and cost-effectiveness—giving you the capabilities of a full development team at a fraction of the cost. This isn't about shortcuts or building something that can't scale. It's about strategic choices that let you move fast, validate ideas with real users, and iterate based on feedback.
Begin by validating your core concept before building anything. Once validated, set up Supabase first, design your data model, and configure authentication. Then build your Bubble interface, connecting it to your Supabase backend. Finally, add n8n to automate processes that make your application feel professional and complete. Launch in weeks, not months, and start learning from real user behavior. Remember that solo-founded startups now represent over half of successful exits, proving you don't need a co-founder or large team to build something meaningful.
Key Takeaways: Solo founders can build production-ready MVPs for under $50/month initially. Speed to market is dramatically faster than traditional development—weeks vs. months. The stack scales from prototype to production without rebuilding. N8n's automation capabilities create the impression of a full operations team. Security and best practices can be implemented from day one using built-in features.
Ready to start? Begin withBubble,Supabase, and n8n today. All three platforms offer free tiers perfect for getting started, and you can have a working prototype running within days.
