Build steps with BridgeMind
- 1Write a one-paragraph brief for a SaaS app: who it's for, the 3 core screens, and what people pay for.
- 2Install BridgeMind (Mac, Windows or Linux), connect your AI subscription — for example Claude Pro — and create the project.
- 3Let the agents turn the brief into a task plan, and approve the plan before they build.
- 4Run agents in parallel on separate features — for example one on sign-in, one on the main screen.
- 5Connect Stripe for payments (2.9% + 30¢ per US card payment) and test a purchase in test mode.
- 6Review each change in the preview and request fixes the way you'd brief a contractor.
- 7Deploy to Railway (Hobby $5/month includes $5 of usage) and add your domain.
- 8Put it in front of five real users before adding more features.
What the first version includes: Sign-up and login · A dashboard with the core feature · Monthly subscription billing · Account settings and emails.
Your build brief
Paste it into BridgeMind as your first message — it already knows the scope, the stack and your budget.
Build the first version of a SaaS app: [your idea in one sentence — e.g. a habit tracker for small teams]. This version includes: - Sign-up and login - A dashboard with the core feature - Monthly subscription billing - Account settings and emails Tech and services: - Sign-up and login by email — use a proven auth library or Supabase Auth, don't write auth from scratch. - Store data in Postgres (on Railway or Supabase). - Payments with Stripe Checkout — build and test in test mode first. - Transactional emails through Resend. - Deploy on Railway, with every secret in environment variables. How to work: - First turn this brief into a task plan and show it to me before writing any code. Split the work so separate agents can build "Sign-up and login" and "A dashboard with the core feature" in parallel, and give me a one-line summary after each task. - Build only what is listed above; ask me before adding anything else. - Keep tools and hosting under about $42 a month and aim for a working prototype in about a week.
