GUI

★★☆☆☆

DoomsDay has a rather basic GUI. Categories can be dragged. Categories and individual modules can be expanded with right click, though expanded modules render underneath categories that were opened after their own category has been opened, making for a frustrating experience when changing module settings. The only possible customizations are changing colors, and changing the width of category titles. Black bars in the GUI can be dragged, stretching elements.

Visuals

★★★☆☆

The visual modules all work* with minimal performance impact, but lack visual polish. Chams can sometimes flicker and ESP outlines an entire square around held items, but both consistently work.
*I did not test LogOutSpots

Combat

★★★☆☆

There are a good variety of modules, though Hitboxes, Misplace, and Velocity are detected by most modern anticheats, even with low settings. Reach also flags when on low ping or high reach values. The lack of lag-based modules feels outdated compared to many other ghost clients. Most configs that bypass use just TriggerBot, with some using Aim Assist as well despite the aim assist being snappy and probably more of an annoyance than a help.

Movement

★★☆☆☆

Not recommended to use anything other than Sprint or Blink if trying to remain undetected.

Utility

★★★★☆

While it has few settings compared to blatant clients, the existing utility modules work well enough - just double check that they are configured for the anticheat you’re on.

Documentation / Support

★★☆☆☆

There is no comprehensive documentation of DoomsDay. Support is offered through their Discord server, though I never experienced any issues that would require creating a ticket.

Overall Module Variety

Overall Module Quality

★★★★☆

DoomsDay is easily the best free ghost client for multiple versions (not that is has much, if any, competition in the free tier), though its claims to being a ghost client may be tenuous at times. If looking for a free client to be used on an SMP, or with minor settings in PvP, it is perfectly serviceable, though the relatively low customizability makes it no ideal for servers with strict or quickly updating anticheats.
