AI SaaS Build Workflow -> From Idea to Launch in 21 Days
The exact workflow used by Prajwal Tomar (@PrajwalTomar_ on X) and his agency Ignite Lab to ship 40+ MVPs in 12 months covering every phase from raw idea to live product. Uses ChatGPT for planning, UX Pilot for rapid design, Lovable for front-end building, Codzer (Cursor) for complex logic, Code Rabbit for AI code review, and Vercel for deployment. Designed for solo founders and non-technical builders who want to ship a SaaS in 21 days without a team.
