Bought from the old store?

Tweakbench relaunched in December 2025: a new store, and 22 of the classic plugins rebuilt from scratch for modern systems - 64-bit, macOS, Windows and Linux, in VST3, AU, CLAP and LV2.

Accounts from the old site didn't carry over, so signing in with your old details won't work. Your purchase history did. Enter the address you bought with and, if it's on record, you can create a new account and find the Tweakbench Classic Collection - the original 32-bit Windows plugins - waiting under My Downloads, along with an upgrade code for the new store.
