What This Stack Does
The indie hacker philosophy is simple: build something people want, charge money for it, and keep your costs low enough that you are profitable from your first paying customer. This is the opposite of the venture-backed startup model where you raise millions, hire dozens of engineers, spend lavishly on cloud infrastructure, and hope to figure out monetization before the money runs out. Indie hackers optimize for speed over perfection, revenue over growth metrics, and ownership over scale. Every tool in this stack was chosen with three criteria in mind: Does it make you faster? Does it keep costs under control? Does it let you maintain full ownership and avoid platform dependency? The total cost of this stack is approximately $50 per month — Cursor Pro at $20, a VPS for Coolify at $5-10, Supabase Pro at $25 if you outgrow the free tier, and everything else is either free or has a generous free tier. Compare this to the typical startup stack of Vercel Pro ($20), PlanetScale ($39), Auth0 ($23), AWS services ($50+), and Heroku ($25+) and you are looking at $150+ per month before you have a single user. For a solo founder, that difference between $50 and $150 is the difference between being profitable at 5 customers versus 15 customers.
From Prototype to Product in Record Time
Bolt.new is the secret weapon that most indie hackers underestimate until they try it. Built on StackBlitz's WebContainers technology, Bolt.new generates fully functional web applications from natural language descriptions in seconds — not minutes, not hours, seconds. You describe what you want, and Bolt.new creates the project structure, installs dependencies, writes components, sets up routing, and gives you a live preview running entirely in your browser. This is not a toy that generates boilerplate — Bolt.new can produce sophisticated applications with authentication flows, database schemas, API routes, and responsive UI. For an indie hacker, Bolt.new transforms the ideation and validation phase. Instead of spending a weekend building an MVP to test whether anyone cares about your idea, you spend 30 minutes prompting Bolt.new and have a functional prototype you can show to potential customers that same afternoon. The code it generates is real, editable, and deployable — you can export it, open it in Cursor, refine it, and ship it. Bolt.new is not a replacement for serious engineering, but it is an extraordinary accelerator for the zero-to-one phase where speed of validation matters more than code quality.
Cursor is the development environment where you will spend most of your time once you move past the prototype stage. For indie hackers, Cursor's value proposition is singular: it makes a solo developer as productive as a small team. The AI agent mode can implement entire features from a description — it reads your existing codebase, understands your patterns and conventions, writes new code that fits naturally, creates necessary files, updates imports, and even runs your tests to verify the changes work. A feature that might take a solo developer 4 hours to implement manually can often be completed in 30-60 minutes with Cursor's agent handling the mechanical work while you guide the architecture and review the output. The Tab completion is equally valuable for day-to-day coding — Cursor predicts not just the next line but entire blocks of code based on your current context, and its predictions are accurate enough that many developers report accepting 60-70% of suggestions. At $20 per month, Cursor is the single highest-ROI tool in this stack. It does not just save time; it fundamentally changes what a single person can build and maintain.
Backend and Hosting on a Bootstrapper's Budget
Supabase is the backend that lets indie hackers skip the most time-consuming part of building a SaaS product: the infrastructure layer. A typical SaaS needs a database, user authentication, file storage, real-time capabilities, and API endpoints. Without Supabase, building this infrastructure means choosing and integrating separate services for each — a database host, Auth0 or Clerk for authentication, S3 for file storage, Pusher for real-time, and a backend framework for API routes. With Supabase, you get all of this in a single platform with a single dashboard, a single set of client libraries, and a single billing relationship. The PostgreSQL database is not a toy — it is a full-featured relational database with row-level security policies that let you define access control rules directly in the database layer, eliminating the need for a separate authorization service. Supabase Auth supports email/password, magic links, OAuth providers (Google, GitHub, Twitter, Apple), and phone authentication out of the box. The storage service handles file uploads with automatic CDN delivery. The real-time engine pushes database changes to connected clients instantly. For indie hackers, the free tier covers most pre-launch and early-stage needs, and the Pro tier at $25/month scales to thousands of users without requiring any infrastructure management.
Coolify is what makes the $50/month budget possible. Traditional deployment options for indie hackers are either expensive or complex: Vercel and Netlify charge $20/month per project on Pro plans and add charges for bandwidth, serverless function invocations, and build minutes. AWS, GCP, and Azure are powerful but require significant DevOps knowledge and can produce surprising bills. Heroku starts at $7/month per dyno and scales to hundreds quickly. Coolify flips this equation by giving you a self-hosted Vercel-like experience on a $5-10/month VPS. You install Coolify on a Hetzner, DigitalOcean, or Vultr VPS, point your repositories at it, and get automatic deployments on git push, free SSL certificates via Let's Encrypt, database provisioning with a click, and environment variable management through a clean web interface. A single $10/month VPS with 4GB RAM can comfortably host 5-10 applications, multiple databases, and handle thousands of daily active users. That is $10 total, not $10 per application. For indie hackers running multiple projects — which most do, since the model is to launch multiple small bets — Coolify's economics are transformative. You go from paying $100-200/month across various hosting platforms to paying $10/month for everything on a single server you control.
The Bottom Line
Claude rounds out this stack as the force multiplier that handles everything outside of code. Indie hackers are not just developers — they are also the marketer, copywriter, customer support agent, documentation writer, and content creator for their products. Claude handles all of these roles with remarkable quality. Need a landing page headline and subheadline? Claude generates 10 options in 30 seconds. Need to write documentation for your API? Claude reads your code and produces clear, accurate docs. Need to draft a launch post for Product Hunt, Twitter, or Hacker News? Claude understands the conventions of each platform and adapts the tone accordingly. Need to respond to customer support emails professionally while you are heads-down coding? Claude drafts responses that you review and send in seconds. Obsidian serves as the knowledge base where you capture everything — product ideas, customer feedback, competitive research, marketing plans, technical decisions, and lessons learned. Its local-first Markdown files mean your knowledge base is portable, searchable, and permanent. Linear provides just enough project management structure to keep a solo founder organized without the overhead of Jira or the chaos of managing tasks in a text file. Its keyboard-driven interface is fast enough that updating task status feels effortless rather than burdensome. Together, these tools create a system where a single person can build, launch, market, and support a profitable SaaS product at a cost that is profitable from the very first customer.
