Freemium4.8
§ Recipe
Build a SaaS.
The leanest path from idea to revenue. Every tool here has a generous free tier or open-source fallback, and every step pulls its weight — no decorative infra, no premature scale.

01Before you write code, argue with Claude about the schema, auth model, and pricing tiers. It catches half of the shape you'd otherwise refactor on day 14.
UI scaffolding
02v0
Vercel's AI app builder for React, Next.js, Tailwind, shadcn/ui, and full-stack prototypes.
Coding & DevelopmentFreemium4.4Describe a dashboard, get working Tailwind + shadcn/ui React. Not pixel-perfect, but 80% of the chrome done in minutes means you ship the actual business logic faster.
Code editor
03Cursor
AI-native code editor with agents, Composer, codebase context, and multi-model support.
Coding & DevelopmentFreemium4.9This is where the V0 output becomes a real codebase. Multi-file edits, agentic refactors, tab-complete that understands your domain. Non-negotiable.
Full-stack prototype
04Bolt.new
StackBlitz browser AI builder for full-stack web apps with token-based usage.
Coding & DevelopmentFreemium4.3When you want a throwaway Next.js + Supabase prototype live in 5 minutes to test a flow before committing. Wasted iterations are the expensive kind.
Launch research
05Who are the three closest competitors, priced how, positioned against whom? Perplexity with citations is faster than any human consultant and less biased than Twitter.
Internal docs
06Notion AI
AI writing, summarization, search, and knowledge assistance inside Notion workspaces.
ProductivityFreemium4.3You'll forget why you made every decision. Notion AI will remember and summarize, and turns your scattered product thinking into an actual living spec.
