I Built SaaS! POST Data, Get an API — No Backend Required

Hi everyone,

So I built Supaserver — a backend that creates itself.

What Is Supaserver?

Supaserver is a REST API proxy that automatically creates endpoints and stores data. No configuration, no boilerplate, no deployment headaches.

Here's the entire workflow:

Store data (endpoint is created automatically)

curl -X POST https://api.supaserver.app/tasks?apikey=dk_705b3400ab
-H "Content-Type: application/json"
-d '{"title": "Launch on DEV.to", "done": false}'

Retrieve it immediately

curl https://api.supaserver.app/tasks?apikey=dk_705b3400ab

That's it. No setup. The /tasks endpoint didn't exist before — Supaserver created it when you sent data.

Why I Built This

I wanted something where I could just send data and have it stored, retrieved, updated, deleted — without thinking about databases or servers.

Quick Examples

Create and Fetch Users

await fetch('https://api.supaserver.app/users?apikey=dk_705b3400ab', {
  method: 'POST',
  body: JSON.stringify({
    name: 'Alex',
    email: '[e-mail]'
  })
});

Get all users

const response = await fetch('https://api.supaserver.app/users?apikey=dk_705b3400ab', {});
const users = await response.json();

Full CRUD Out of the Box

Method	Endpoint	Action
POST	/tasks	Create new task
GET	/tasks	Get all tasks
GET	/tasks/:id	Get single task
PUT	/tasks/:id	Update task
DELETE	/tasks/:id	Delete task

All endpoints support filtering, sorting, and pagination:

GET /tasks?sortBy=createdAt&sortOrder=desc&limit=10

What's Under the Hood

• NestJS backend with MongoDB
• JWT authentication + API keys
• Data isolation — each user's data is completely separate
• Built-in request tester — like Postman, but in your browser

Who Is This For?

• Indie hackers building MVPs fast
• Hackathon participants who need a backend in minutes
• Students learning frontend without backend complexity
• Developers prototyping ideas before committing to infrastructure

Try It Free

Supaserver is live at supaserver.app

You can:

1. Sign up (free)
2. Get your API key
3. Start sending data immediately

No credit card, no complex setup.

I'd Love Your Feedback, especially if you've launched a SaaS project ;)

I'm curious what you think:

• Is this useful for your workflow?
• What features would make it better?
• Would you use it for a real project?
