Pure Faithful
beta 1.7.3 as it was, safe and fast.
Free and open source. For Windows, with Prism Launcher and a Minecraft account that owns the game. As a zip file.
Playing it
- Install Prism Launcher and sign in with your Microsoft account.
- In Prism: Add Instance, then Import, and choose the zip you downloaded.
- Launch it. Prism fetches beta 1.7.3 itself from Mojang; everything else is in the zip.
Your worlds stay in beta's own format: they open in the original game too.
What it is
Minecraft beta 1.7.3 exactly as it was, with only the problems fixed that come from its age. Beta's own bugs and quirks stay.
- Runs on today's Java, in its own window: resizable, sharp on high-resolution screens, fullscreen with F11.
- Safe online: logins and skins go to Mojang over HTTPS, sounds come over HTTPS and are checked, and your account's token is never sent in the clear.
- Beta's own sounds for the bow, doors and explosions, where launchers today give later recordings.
- Faster, with the same picture; servers make new land in less time.
- Saves that a crash or power cut can't damage. A part of a world that can't be read is kept and reported, never replaced with new terrain.
Old Faithful is Pure Faithful plus fixes for beta's own bugs, and Still Faithful adds the polish later versions brought. macOS and Linux come later.

Privacy
Pure Faithful sends nothing to its makers; there's no server of ours. The game talks to Mojang to sign you in, and to the servers you join. On its first start it also fetches beta's own bow and door sounds from an archive of beta's files kept by Modification Station, a community of beta modders; its README says how to turn that off.
