Hantek is the name, or at least one of the names, many people rebadge
them. There is openhantek6022 which works for the cheapest scope.

It's OK for DC and audio, which is all I need these days. If I have
frequencies a bit higher to deal with, I haul out my ancient Tek 465B,
which weighs about fifty times as much as the Hantek device.
