CustomHud is a highly configurable variable-based text HUD. While there's mods that also add text HUDS or allow you to customize the F3 debug screen, they aren't fully customizable, their customization is mostly limited to colors and if a line/module is displayed or not. CustomHud allows you to put the data exactly where you want (in addition to full color support, including hex), and it does it with a "variable" type system.
In the profile file you write what you want to see and use "variables" like {fps}, {version}, {block_x}, etc where you want them to be. There's also a feature called conditionals, which allows you to change what's displayed depending on the output of certain variables. Documentation and in-depth examples of variables and conditionals can be found in the wiki.
Here's a full example:
The config that produced it:
Minecraft {version} ({client_version})
&a{fps}&f/{max_fps} fps {{vsync, "(vsync)", ""}}
&cX&aY&bZ: &c{bx} &a{by} &b{bz}
Facing: &a{facing}&f (&a{yaw}&f, &a{pitch}&f)
Looking {{tbx, "at {tbx} {tby} {tbz}", "into the abyss"}}
Mem: &a{memory_used_percentage}%&f of {total_memory}MiB, &a{allocated_percentage}%&f allocated
{{tps, "&a{tps}&f tps (&a{ms_ticks}&f ms ticks)", ""}}
{{nether, "Overworld:", "Nether:"}}&a {nx} {nz}
Time: &a{real_time:HH:mm}

This is a Fabric Mod, there's no plans for a Forge port, but the license allows you to port it yourself if you wish.
