# Deploy Your Flask App on Kuberns in One Click

Run Flask web apps and APIs in production without setting up Gunicorn workers, Nginx, Dockerfiles, or cloud infrastructure. Kuberns deploys and manages your Flask app as a long-running service, handling scaling, monitoring, and security automatically.

## What We Offer

### Zero-Configuration Flask Deployment

Push your Flask repository, and Kuberns automatically configures the WSGI server, process model, and runtime needed for production Flask apps.

### Auto Scaling & Monitoring

Built-in logs and metrics help you understand request load, memory usage, and application behavior without external monitoring tools.

### Secure AWS Infrastructure

Every Flask deployment runs on optimised AWS infrastructure with isolated environments and lower compute costs compared to standard cloud pricing.

## 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It's a classic platform, but outdated for today’s backend deployment needs.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 Flask backend applications with persistent processes, background workers, and long-running requests.
- No serverless cold starts or function timeouts
- Persistent servers, workers, cron jobs supported
