## Health v2 (maintenance only)
Score: 94/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)

- inputs: {"age_days": 1073, "days_push": 7, "days_rel": 8, "gap_med": 11, "n_releases_24m": 44}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Aspire is a multi-language, code-first toolchain from Microsoft for composing, running, debugging, and deploying distributed applications. Developers describe services, frontends, containers, and databases in an AppHost (C# or TypeScript), and the Aspire CLI runs the app locally with OpenTelemetry-based observability and carries the same definition into deployment.

## Use cases
- orchestrate local development of multi-service distributed apps
- define service dependencies and startup ordering in code
- add OpenTelemetry observability dashboard to my microservices
- deploy a distributed application defined as code to the cloud
- run Redis, databases, and frontends together during development
- compose Node.js, Python, and .NET services in one app definition
- manage local dev environment for microservices without docker-compose

## When to choose
- you build distributed applications with multiple services, containers, and backing stores
- you want code-first orchestration with built-in OpenTelemetry observability
- you want the same app definition to drive both local dev and deployment
- you work in .NET or TypeScript and want first-class tooling and IDE integration

## When to avoid
- you have a single monolithic application with no multi-service composition needs
- you are fully committed to existing docker-compose or Kubernetes-native workflows
- you need a mature orchestration platform for large-scale production scheduling rather than dev-to-deploy tooling

## Facets
- artifact type: framework
- maturity: active
- function: deployment, monitoring, tracing, developer-tools, configuration-management, container-orchestration
- domain: cloud-computing, microservices, developer-tools, backend
- platform: cross-platform, windows, cli, cloud
- tags: apphost, distributed-applications, opentelemetry, local-development, code-first-orchestration, multi-language, csharp, typescript, microsoft, devops, linux, macos, docker, kubernetes
