Six Monthly Bills Pretending to Be Infrastructure
A lot of indie SaaS apps start as a working prototype and quietly turn into a pile of subscriptions. Auth comes from one vendor. The database is Airtable or a spreadsheet. Uploads live somewhere else. Email comes from another dashboard. Payments are wired through Stripe, and anything that does not connect cleanly gets pushed through Zapier or Make.
That can be fine while you are proving the idea. It becomes a problem when the app has users, production bugs, real data, and no clear owner for the stack. At that point, the goal is not to buy another tool. The goal is to collapse the stack into fewer moving parts.
What You Are Actually Replacing
Most vibe coded SaaS products end up duct taped together from a list like this:
- Auth0 or Clerk for login
- Airtable or Google Sheets pretending to be a database
- Cloudinary for file uploads
- Zapier or Make for automation
- Vercel or Netlify for hosting
- SendGrid or Mailgun for email
- Stripe for payments
Seven tools means seven dashboards, seven invoices, seven permission models, and seven places a production issue can hide before you even start debugging your own code.
What Replaces All of It on AWS
| Tool You Are Probably Paying For | What Replaces It |
|---|---|
| Auth0 / Clerk | Cognito |
| Airtable / Google Sheets | RDS or DynamoDB |
| Cloudinary | S3 |
| Zapier / Make | Lambda plus EventBridge |
| Vercel / Netlify | Amplify |
| SendGrid / Mailgun | SES |
| Stripe | Stripe stays |
The One-Account Stack
Cognito for Auth
Cognito replaces Auth0 or Clerk with user pools, sessions, sign-in flows, and identity plumbing inside the same cloud account.
RDS or DynamoDB for Data
Use RDS if your app needs relational data. Use DynamoDB if your access patterns are simple and document-style scale matters more.
S3 for Uploads
S3 replaces separate file storage vendors with durable object storage that every other AWS service already knows how to use.
Lambda and EventBridge for Automation
Instead of paying per task in an automation tool, use event-driven functions for predictable app workflows and background jobs.
Amplify for Hosting
Amplify gives builders a guided path for hosting, auth integration, environments, and deployment without starting from raw infrastructure.
SES for Email
SES handles transactional email at cloud-provider pricing once your usage grows past what the usual email SaaS tiers make comfortable.
Stripe is the exception. Payments are worth keeping with a specialist processor. The point is not to make every line item disappear; it is to stop turning every ordinary infrastructure need into another SaaS subscription.
Why This Matters More Than People Think
Where to Start If This Is Your First Time Touching Real Infra
Do not start with IAM policies, VPC design, and every possible production hardening detail. That is how people quit in week one. Start with the piece that feels closest to the tools you already know.
- Stand up your frontend on Amplify.
- Wire in Cognito for auth through Amplify's built-in flow.
- Connect a database: RDS for relational data, DynamoDB for simpler access patterns.
- Move file uploads to S3.
- Keep Stripe exactly where it is.
That is the full stack: one provider, one bill, and pieces designed to talk to each other because they come from the same company.
The Bad Version of This Move
Do not try to migrate everything at once over a weekend while your app is live with real users. Move one piece at a time, starting with whatever is costing the most money or breaking the most often. Auth and database usually come first. Email and automation can come later. Stripe does not need to move.
Also run the math before changing production. If you are paying for Auth0, Airtable, and Cloudinary combined, AWS may reduce cost and complexity. But cloud pricing still depends on usage, storage, traffic, and the services you choose. Know your numbers before you touch the stack.
