The Julia ecosystem contains over 10,000 packages that are registered in the General registry, which means that finding the right package can be a challenge. Fortunately, there are services that can help navigate the ecosystem, including:
JuliaHub — a JuliaHub service that includes search of all registered open source package documentation, code search, and navigation by tags/keywords.
Julia Packages — browse Julia packages, filter by categories, and sort them by popularity, creation date or date of last update. Also supports browsing package developers.
Julia.jl — a manually curated taxonomy of Julia packages (category information for JuliaPackages is derived from this as well).
Julia Package Comparisons - a website to help Julia users discover and choose between packages.
