The Tool Stack for Non-Technical Founders Building With Claude Code

Claude Code can write your whole SaaS, but it can't be your whole SaaS. A real product also needs somewhere to store data, somewhere to live online, a way to take payments, a way to send emails and a way to see who's using it. This guide covers the non-technical founder tools that fill each of those gaps.

It's written for founders who build with Claude Code in the desktop app or the browser and don't write code themselves. For each layer you'll get one tool that works well with Claude Code, how it connects, and what it costs today.

The picks below aren't the only good options. They're a set that fits together, connects to Claude Code without developer setup, and costs very little until you have paying customers.

Which non-technical founder tools do you need?

You need six layers: building, database, hosting, payments, email and analytics. Claude Code builds the product, and each of the other five tools does one job your product can't do on its own.

Building: Claude Code and GitHub

Claude Code is where you do the work. You describe what you want in plain sentences, and it writes the code, runs it and fixes what breaks. It comes with Claude's paid plans, starting with Pro.

GitHub is where most projects keep their code. A repository (a folder of your project's files with a full history of every change) lives there, so you can roll back a bad change, and hosting services like Vercel can build your site straight from it. GitHub's free plan includes unlimited private repositories.

I don’t have my code saved anywhere except this computer. Set up a private GitHub repository for this project and save my work there regularly, with a short note on what changed each time.

Database: Supabase

A database is where your product remembers things: who signed up, what they bought, what they saved. Supabase gives you a database plus user sign-in and file storage in one place.

Its free plan includes a 500 MB database and up to 50,000 monthly active users, enough for an early SaaS. Two catches: free projects pause after a week without activity, and you can only have two active free projects. The Pro plan starts at $25 a month and never pauses.

Supabase is in Claude's connector directory. Once it's connected, Claude Code can create tables, look at your data and check logs for you. Supabase recommends scoping the connection to one project and testing changes on a development copy before they touch live data, so ask Claude Code to do the same.

Hosting: Vercel

Hosting is the service that keeps your SaaS online, so anyone can visit it at your domain. Vercel builds your site from your code and puts it live every time you save a change.

The free Hobby plan is for personal, non-commercial use, which makes it a good fit while you build. Once you take payments, you need Pro at $20 a month, which includes $20 of usage.

Vercel is in Claude's connector directory too. Through it, Claude Code can manage projects and deployments (each version of your site that goes live) and read deployment logs when something breaks.

Payments: Stripe

Stripe takes card payments and runs subscriptions. There's no setup fee or monthly fee; you pay per successful payment.

For domestic cards, the fee is 2.9% plus 30¢ per payment, with extra for international cards. If you use Stripe Billing to run subscriptions, it adds 0.7% of the billed amount on the pay-as-you-go plan.

Stripe has an official connector in Claude's directory. When you sign in, you choose which Stripe accounts Claude Code can reach, and you can give it a sandbox (a test version of your account with fake money) instead of your live account. Stripe also asks you to confirm certain actions, such as refunds, before they happen.

I’ve connected Stripe. Use my sandbox, not my live account, and set up a monthly plan at $19 with a 14-day free trial. Show me the checkout page before you go further.

Email: SimpleSends

Your SaaS needs to send emails that one person gets because of something they did: a welcome email when they sign up, a link when they forget their password, a receipt after they pay. These are called transactional emails, and you send them through a transactional email service.

SimpleSends is a transactional email service built for people who build with Claude Code but don't write code. Setup works like any email service. You create an account, verify the domain you send from by adding a few DNS records (settings that tell the internet how your domain works) where your domain is registered, and your live project gets a secret key and a small piece of sending code.

What's different is the experience after that. The sign-up, connect steps and help are written in plain English, without developer jargon. Day to day, you work with Claude Code in the chat instead of a dashboard. Claude Code designs, writes, builds and changes each email, and because it can read your send logs through SimpleSends, it can tell you whether an email went out and help work out why one didn't.

To connect it:

1. Sign up on the SimpleSends website and follow the steps there to set up the email address you'll send from. To send from your own domain, this includes adding a few DNS records where your domain is registered.
2. In Claude Code, open Customize, then Connectors, choose Add, then Add custom connector. Name: SimpleSends. MCP server URL: https://mcp.simplesends.com/mcp
3. When Claude prompts you to connect, log in to SimpleSends.
4. Back in the Claude Code chat, tell Claude Code: "I've connected SimpleSends for all transactional email." It takes it from there, including adding what your project needs to send email.

Once your SaaS is live, its emails go out from your project directly, at any hour, without Claude Code or the chat involved. To see which emails a typical SaaS sends, read 12 transactional emails every SaaS needs. Pricing starts free, with 100 emails a day on the Starter plan, and paid plans from $14 a month.

Analytics: PostHog

Analytics shows you who visits your SaaS, where they come from and where they get stuck. PostHog covers product analytics (what people do once they're inside your product) and records sessions so you can watch where people hesitate.

Its free tier includes 1 million analytics events and 5,000 session recordings a month, and usage stops at those limits, so you can't be charged by surprise. PostHog is in Claude's connector directory, so you can ask Claude Code questions like "how many people signed up this week?"

If you only want page views, Vercel's built-in Web Analytics includes 50,000 events a month on the Hobby plan, and Claude Code can query it through the Vercel connector.

How do these tools connect to Claude Code?

Each tool connects through a connector, which is Claude's name for an MCP server. MCP (Model Context Protocol) is an open standard that lets Claude Code talk to other services. A connector gives Claude Code tools for one service, such as "list my database tables" or "show the latest deployment".

There are two ways to add one, both in Claude Code's settings:

Either way, you sign in to the service in a pop-up window, so you never type a password into the chat. For the full walkthrough, see how to connect an MCP server to Claude Code, and for more connectors worth adding, see the MCP servers worth connecting to Claude Code.

Two things are worth knowing. First, connectors are for building. Once your SaaS is live, it talks to Supabase, Stripe and SimpleSends directly, using secret keys stored in your hosting settings. An API key is a password one piece of software uses to prove who it is to another. Second, a connector acts with your account's permissions, so keep Claude Code's approval prompts on and read what it plans to do before you say yes.

I’ve connected Supabase, Vercel, Stripe and SimpleSends. Before you change anything in any of them, tell me in plain English what you’re about to do and wait for my OK.

What does the stack cost each month?

While you build, the stack costs about $20 a month: your Claude plan. Once you charge customers, plan on about $65 a month plus email and Stripe's per-payment fees.

Prices checked October 2026, in USD, before tax.

To put Stripe's fees in context: 20 subscribers paying $50 a month is $1,000 in sales. Card fees on that come to $35, and Stripe Billing adds $7, so you keep $958 before tax.

Costs grow with usage. Supabase and Vercel both charge for usage above what Pro includes, and both offer spending limits: Supabase Pro has a spend cap on by default, and Vercel lets you set a budget with alerts.

Which tool should you set up first?

Set up the tools in the order your product needs them. Most founders go in this order:

1. Claude Code and GitHub, so your work is saved from day one.
2. Supabase, as soon as your product needs sign-ups or saved data.
3. Vercel, when you want to share a working version with someone.
4. SimpleSends, as soon as people can sign up, because sign-up and password reset emails come first.
5. Stripe, when you're ready to charge.
6. PostHog, before launch, so you have data from your first visitors.

Leaving email until launch day is a common mistake: sign-ups, password resets and receipts all depend on it. When you're close to going live, the SaaS launch checklist walks through everything else.
