Recommended tool
BridgeMind
Desktop app (Mac, Windows, Linux) where AI agents plan, build, test and deploy your product
Basic · $16/mo
+ Your own AI plan (Claude, ChatGPT or Grok) ~$20/mo
Why: Several AI agents plan, build, test and deploy the features in parallel — the closest thing to a small dev team, on your own AI subscription.
Best for: Solo founders shipping a real multi-feature product who want several agents working in parallel. Not for: Engineers who only want smarter autocomplete in their current editor.
If you only need to sell a handful of products, a hosted store builder can beat a custom build on cost.

Build steps with BridgeMind
- 1Write a one-paragraph brief for an online store: 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: Product catalog and pages · Cart and checkout · Order emails · Simple admin for products.
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 an online store: [your idea in one sentence — e.g. a shop for handmade ceramics]. This version includes: - Product catalog and pages - Cart and checkout - Order emails - Simple admin for products Tech and services: - 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 "Product catalog and pages" and "Cart and checkout" 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 a weekend.
