- inputs: {"age_days": 5536, "days_push": 0, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Zato is a Python-based open-source platform for ESB, SOA, REST API integration, and cloud orchestration. It lets teams automate, integrate, and orchestrate business systems, APIs, workflows, and hardware assets through Python services.

## Use cases
- integrate REST APIs across enterprise systems in Python
- build an enterprise service bus for healthcare HL7 and FHIR systems
- orchestrate workflows between cloud and on-premise services
- expose internal services as REST APIs with an API gateway
- automate business processes across telecom and financial systems
- connect legacy systems to modern APIs without heavy coding

## When to choose
- you need Python-based enterprise integration and API orchestration
- you work in healthcare, telecom, defense, or finance with interoperability needs like HL7/FHIR
- you want a self-hosted iPaaS/ESB with a dashboard and low-code configuration

## When to avoid
- you only need a lightweight HTTP microservice framework without integration tooling
- you require a permissive license since Zato is AGPL-3.0
- you want a fully managed cloud integration service rather than self-hosted software

## Facets
- artifact type: framework
- maturity: active
- function: api-framework, http-server, middleware, workflow-automation, webhook, scheduling, microservices, api-gateway
- domain: backend, apis, healthcare, erp, developer-tools
