Hammer++
Source
Hammer++ is a community-made modification of the Valve Hammer Editor for Source that provides an updated, more stable, feature-rich version of the editor.
Hammer++ currently supports the following branches of the Source engine:
Counter-Strike: Global Offensive (does not work for 
CS2, only CS:GO through csgo_legacybranch, so it is essentially deprecated for that use. Still usable for
and 
however, as well as third-party games running on CS:GO engine branch.)
Team Fortress 2
Counter-Strike: Source
Source 2013 Multiplayer
Source 2013 Singleplayer
It is also included with 
Military Conflict: Vietnam, in lieu of vanilla Hammer.

Caveats
Warning:Does not support some features from 
Hammer 4.x, such as "Convert WAD to VMT...", or loading GoldSrc ".MAP" files directly.
Bug:Always uses Windows's high-DPI scaling setting, even when scaling override mode is set to "Application" in 
File Explorer's compatibility settings for 
hammerplusplus.exe. This can result in less real estate than Hammer 4.x, depending on Windows settings.Warning:Ignores %notooltexture, with no option to disable this change.Additional bugs can be found in the official issue tracker, which is no longer maintained.
Bugs/Limitations with unsupported games
Black Mesa
Works with Source SDK 2013 Singleplayer version. However, there are some bugs and issues due to which you will not be able to work in it constantly.
New lights broken
Entities with "newLight_" and "newLights_" prefixes doesn't work with SmartEdit.
This new light point placed with Entity Tool.
Attempt to replace an entity with one of these will cause obsolete.
npc_gmanis replaced bynewLight_Point.
This because of new lights use big letters in classname. Because of this, Hammer++ cannot read them normally. You can fix it if replace big letters with small, with this the game will work with new lights the same as before. However, you will still not have any preview for new lights.
Note:Similar issue have npc_xortEB.Lightmapped_4WayBlend is missed
You will not be able to work with xen levels, since xen uses this shader for surfaces everywhere. Earthbound outdoor levels as well.

Hammer++.

Hammer++.
The only workaround is Hammer++ version for Counter-Strike: Global Offensive. This is the only version of Hammer++ that support Lightmapped_4WayBlend. However, you will need to port game's assets, because Counter-Strike: Global Offensive don't use and don't support old models format.
No surface blend preview
WorldVertexTransition replaced by LightmappedGeneric with all its features. This means that you will not be able to see blended surfaces in Hammer++, since this feature is not provided.

GRPortal is missed
This shader uses for nihilanth's portals.

Physics Tool doesn't work properly with new ragdoll entities
prop_ragdoll_original and misc_dead_hev are ragdoll entities, Hammer++ doesn't know about this. You can add ragdoll() in FGD for these entities to fix this.
prop_ragdoll_original and misc_dead_hev simulating as general objects, but prop_ragdoll works fine.
Confirm:More ? Portal 2: Community Edition
Mainly works with Counter-Strike: Global Offensive version. Hammer++ will not provide many features from 
Strata Source's version of Hammer and its engine (mainly UI elements and how it works with content). Сonvenient of its usage will depends on what you plan to use and how you plan to use it.
Works only models that use format from Counter-Strike: Global Offensive
Strata Source support all model formats from any game, including old games. Hammer++ will work only with models that use format from Counter-Strike: Global Offensive, you'll need to port models if they do not use this format (or use other Hammer++ version if your mod using assets from old games).
No Scale Override preview
In Strata Source static props support Scale Override (similar to 
Source 2). You'll not see changes in Hammer++.
Strata Hammer.
Hammer++.
Custom folder
Strata Source support custom folder. Hammer++ for Counter-Strike: Global Offensive doesn't.
Doesn't read mounts.kv
mounts.kv is a safe way to mount content from other games than traditional gameinfo.txt editing. Hammer++ doesn't read this file.
Escape sequences is not supported
Only Strata Source Hammer version support escape sequences.
Confirm:More ? Garry's Mod
Works fine with Source SDK 2013 Multiplayer version. There are some limitations that can be very annoying.
Doesn't work with Counter-Strike: Global Offensive's content
Models will not work. Most particles and textures as well.
Doesn't read mount.cfg
mount.cfg is quick and easy way to mount content from other games. Hammer++ doesn't read it.
Confirm:More ? Mapbase
Works fine with Source SDK 2013 Singleplayer version. Some custom shaders may work incorrectly. Some custom features will not work as expected with Hammer++ features.
SDK_Cable doesn't work properly
Display skybox instead of a cable texture.
An example.
Spotlight textures doesn't applying to spotlight preview
Mapbase support customization for beam and halo texture. Hammer++ always draw the standart textures.
An example. Used obsolete icon for halo and electric texture for beam.
TeamSpen's Hammer Addons
Not a game, but it have some compatibility issues as well. Some issues make it difficult to use together with Hammer++.
Sprite tries to be applied as model for helper
TeamSpen's Hammer Addons uses model helper for sprite entities, this allows you to place them more accurately than with the white cube. Copy and paste cause helper model to use value from model property name, which sprites use to display sprite texture, this cause helper model to use a non existing model and replace it with placeholder. Fixes with Undo button. Doesn't happen when you place sprite entity via Entity Tool or when you replace an entity with a sprite entity.
An example.
