## What it is
Teletraan is Pinterest's open-source deploy system, written in Java, that deploys code to thousands of services and tens of thousands of hosts in production. It provides zero-downtime deploys, rollback, staging, continuous deployment, and developer-facing features like commit details, deploy comparison, and email/Slack notifications.

## Use cases
- deploy services to fleets of hosts with zero downtime
- roll back bad deploys quickly
- set up continuous deployment pipelines
- get notified on deploy state changes via email or Slack
- compare different deploys and view commit details
- self-host a dedicated deploy system for internal services

## When to avoid
- you primarily deploy containers - Teletraan does not support container-based deploys natively
- you want a full CI pipeline rather than a deploy-focused tool
- you cannot run a deploy agent on each host or add deploy scripts to your applications
- you prefer Kubernetes-native or GitOps-style deployment workflows

## Facets
- artifact type: service
