The package manager
for the Erlang ecosystem
Specify your Mix dependencies as two-item tuples like {:plug, "~> 1.19"} in your dependency list, Elixir will ask if you want to install Hex if you haven't already.
Download rebar3, put it in your PATH and give it executable permissions. Now you can specify Hex dependencies in your rebar.config like {deps, [hackney]}.
Add the Hex dependency to your gleam.toml file using the lustre = ">= 5.2.0 and < 6.0.0" format. Or use the gleam add lustre@5 command.
Getting started
Fetch dependencies from Hex without creating an account. Hex is usable out of the box in Elixir with Mix and in Erlang with Rebar3 . Check our FAQ for commonly asked questions.
Publish packages
Create an account and follow the publishing guide . Your package will be immediately available to all Elixir and Erlang users and the documentation will be available on HexDocs .
Private packages
Publish private packages by creating an organization . Private packages cost $9 / user / month after a free 30-day trial and include fast dependency fetching and HexDocs on the same reliable infrastructure that serves millions of packages daily. See our pricing page for more details.
Dependency policies
Keep dependency rules consistent across projects with signed, organization-managed policies. Free organizations can publish public policies for public Hex packages. Paid organizations can also publish private policies covering public and private packages, visible only to organization members. See the policy guide for details.
