The launcher

A launcher that
reads the catalog.

The catalog is not a website you leave behind. It is the launcher's home screen: pick a pack, press install, and watch every mod arrive with a hash and a version you can check.

What it handles

The parts you would do by hand.

Installs, profiles, native builds, logs. The launcher does the work and tells you what happened in one sentence.

One click, every dependency

The launcher reads the same manifest you see on the site, resolves every mod from Horizon's registry, and checks each SHA-256 before anything touches your disk.

20 packs В· 104 mods

Profiles that stay separate

Each pack gets its own folder, worlds, configs, screenshots, and logs. Removing one pack leaves the others alone.

one folder per pack

Your own mods and folders

Import .hmod, .hnmod, .hpack or .hshader files, or drop a whole mods folder: the launcher walks it, hashes every file and lets you switch each one off. The editor exports a pack back to .hpack.

Native builds with stages

Native mods compile against the engine. The launcher shows each stage, the ETA, and a reason for every mod left out.

Your account stays with Horizon

Sign-in goes through Horizon's official client. The launcher does not see your Microsoft password and does not write a token to a config file or a log.

delegated sign-in

Servers and invites

Start a server from a server-safe pack, share an invite code, and see who is online. UPnP is optional, and the launcher says when it is not available.

LAN + invite

Logs you can read

A crash produces a readable report instead of a wall of stack traces. One click copies the log, pack version, and mod list into a bug report.

The flow

From install to title screen.

Pick a pack

Filter by what you want to do, not by mod names you have to know.
