Flora
summary
Flora started in late 2021 as a meta index that merges Hackage with Cardano and Mlabs packages, surfacing real signals (example: a package with 20 reverse dependencies on Hackage shows 95 labeled users on Flora). It adds concrete metrics like a bus factor (active uploaders in the last two years), exposes the cabal tested-with field and provides get-tested to generate CI JSON. Backend runs Postgres with an all‑in‑one Docker compose, Prometheus and Jaeger for observability, is building a V2 UI, and prototypes an independent TUF implementation and private‑repo deployments.
