## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 4803, "days_push": 1824, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Flynn was an open-source platform-as-a-service (PaaS) written in Go that let developers deploy and scale applications via git push, similar to Heroku. The project is now officially unmaintained, with all public infrastructure shut down and no security updates.

## Use cases
- self-host a heroku-like paas
- deploy apps with git push
- run a private container platform
- scale microservices on my own servers
- alternative to dokku or deis

## When to choose
- you need a historical reference for PaaS architecture or Go systems code
- you want to fork and maintain your own PaaS

## When to avoid
- you want a production PaaS today - it receives no security updates
- you need working release hosting or cluster discovery
- you are starting a new deployment platform project

## Facets
- artifact type: infra-config
- maturity: abandoned
- function: deployment, container-orchestration, microservices, api-gateway, self-hosted
- domain: cloud-computing, self-hosted
- platform: go, self-hosted
- tags: paas, heroku-alternative, unmaintained, git-deploy, container-platform, devops, containers, linux, docker
