# Deploy Your FastAPI App in One Click on Kuberns

Deploy production-ready FastAPI APIs without configuring ASGI servers, Uvicorn workers, Dockerfiles, or cloud infrastructure. Kuberns automatically builds, deploys, and scales your FastAPI app so you can focus on building APIs, not managing DevOps.

## What We Offer

### Zero-Config FastAPI Deployment

Push your FastAPI repository and Kuberns automatically detects your project structure, Python version, and dependencies.

### Auto Scaling & Monitoring

FastAPI apps deployed on Kuberns scale automatically based on real API traffic. Built-in logs, metrics, and alerts help you monitor.

### Secure AWS Infrastructure

Every FastAPI deployment runs on optimised AWS infrastructure with built-in security, isolated runtime environments.

## Get Started with Kuberns in 3 Simple Steps

### Deploy FastAPI apps with Kuberns AI

#### 1. Connect Your GitHub

Kuberns automatically detects your FastAPI structure, Python version, and dependencies from pyproject.toml or requirements.txt.

#### 2. Configure Environment

Add environment variables such as database URLs, API keys, or secrets. Kuberns securely injects them into your FastAPI runtime without hardcoding values.

#### 3. Click Deploy and Go Live

[Kuberns](https://kuberns.com/) builds your container, configures the ASGI server, and deploys your FastAPI app on global AWS infrastructure. Your API goes live in minutes with autoscaling and monitoring enabled by default.

## Why Kuberns is better than other platforms

### Heroku

It's a classic platform, but outdated for today’s backend deployment needs.

- Kuberns is always cheaper than Heroku for the same CPU and RAM
- No 30-second request timeouts, no forced app sleeping, no dyno restrictions
- Autoscaling, logs, and monitoring included (no paid add-ons)

### Render

Render is simple to start, but limited when apps grow or teams scale.

- 85/month on Render vs 15.56 on Kuberns for similar compute
- No slow build queues or complex service wiring
- No hidden fees for autoscaling or background workers

### Railway

Railway is great for prototypes, but less stable for real production workloads.

- Railway costs ~80/month for what Kuberns delivers for 15.56
- No usage caps, build limits, or credit confusion
- Comprehensive dashboards showing query patterns and background job status included

### Vercel

Powerful platform, but not suitable for complex backend deployments.

- Kuberns runs full FastAPI backend APIs with persistent processes and background workers
- No serverless cold starts or function timeouts
- Persistent servers, workers, cron jobs supported

## FAQs to Help You Deploy FastAPI on Kuberns

### How do I deploy a FastAPI project on Kuberns?
