## What it is
Tsuru is an open-source, extensible Platform as a Service (PaaS) that simplifies application deployment and management on top of Kubernetes. It lets developers deploy apps in any language via a CLI, with autoscaling, multi-cluster support, and add-on services like databases and caches.

## Use cases
- self-host a Heroku-like PaaS on Kubernetes
- deploy apps from the CLI without managing servers
- run applications in any language with git push-style deploys
- manage apps across multiple Kubernetes clusters and regions
- autoscale applications based on demand
- attach databases and caches like Redis and memcached as add-on services
- avoid vendor lock-in with an open-source deployment platform

## When to choose
- you want a self-hosted, open-source PaaS atop Kubernetes
- your teams deploy polyglot apps and want a single CLI workflow
- you need multi-cluster or multi-cloud app management
- you want autoscaling and continuous deployment without writing infrastructure configs

## When to avoid
- you just need simple container orchestration without a PaaS layer - use Kubernetes directly
- you prefer serverless platforms like Knative or cloud-managed services like Heroku/AWS App Runner
- your team lacks capacity to operate a Kubernetes-based platform
- you only deploy a single small app where a PaaS is overkill
