So I am trying to understand how people use D&D Beyond for games. I assume you use some form of voice chat such as Discord, D&D Beyond for character sheets, dice rolling and books . . . . but how do you do your battlemaps/VTT or do you even use a battlemap/VTT? https://9apps.ooo/  Maybe you just go with "theater of the mind" style of combat.

How do you as a DM run your games online?

Roll20 for VTT for battles. Theatre of Mind when not in battle.

Discord for OOC and out of session chats.

D&D Beyond for character sheets. Often using Beyond20 so can click on D&D Beyond and see the roll in the VTT. 

-

Although never used, there's also AboveVTT which is a browser based VTT that syncs up with your D&D Beyond campaign and sheets.

Pretty much the same as Cyb3rM1nd.

Roll20 for VTT battles / maps. Theatre of the Mind for everything else.

D&D Beyond for Character Sheets. Word documents for Campaign Notes.

Currently using Zoom for online chat. It's not as good as it used to be as you used to be able to have unlimited session time but, since the close of the pandemic, you now need a subscription for any chat longer than 40 mins. Our group constantly has to restart Zoom whenever the allotted time expires. Not ideal, but saves money for a minor inconvenience.

About the same here. 
We use Roll20 with Beyond20 extension on Chrome. We use a combination of battle maps for grid combat or background images for zone combat depending on the situation. And images for locations and NPC portraits for non-combat/RP.

Whereby for video chat 

Above VTT  - a great free (if you choose not to support via Patreon) resource that works brilliantly with DnDBeyond.

Discord for chat, AboveVTT for the tabletop. And despite being free, AboveVTT now includes dynamic lighting too...

DDB can be instrumental to a group or it can be an accessory.

Some players bring their character sheet to a game on their mobile app, while other players may use paper or google sheets or whatever.  I recently played in a party of 6, 2 of us had DDB sheets, everyone else had paper.

Some DMs may insist everyone build characters on DDB.

DMs can also use the combat tracker to, do what it says it does, keep track of combat while everything else is done on table or over a screen with other tools.

When I DM I let but don't mandate players make characters on DDB through my content sharing.  When planning a session I'll sometimes use the encounter builder, usually with a paper notebook alongside.  When running the game, we'll use paper map aids when needed in person.  Online we'll use various file sharing to share graphics, and virtual white boards when spatial relations matter as it does in combat.

I"m starting to toy with World Anvil as a way to maintain campaigns in general, but still trying to figure out if that's worth my while.

Dropbox Paper for my session notes, homebrew adventure writeups, random encounter tables, etc. I can link to nearly anything, which is great.

Discord for chat: both video and text.  I set up my phone in a tabletop tripod for the video chat and handle text discord chats from my laptop.

Owlbear rodeo for a VTT.  I've been using version 1, but I think I'm going to try the beta of Owlbear rodeo 2.0 next session.

I build encounters in the encounters tool ahead of time, even random encounters:  roll a batch of them from the table and write them down in Dropbox Paper, then build the encounters.  During the session I roll to see IF there is a random encounter, and consult my list of pre-rolled encounters.  I use the encounters tool to run the encounters. I've been trying to remember to use the browser on my tablet for running encounters, as I have owlbear and my notes up in tabs in the browser on my laptop. 

I also use DDB to quickly look up things like spells, magic items, etc.  We had both Web and spike growth active at the same time in yesterday's game.  It was great having both spells up in tabs to refer to as needed. 

Another vote here for AboveVTT. Easy to use, all maps and monster tokens feed through from D&D Beyond, and the encounter builder works well.  There's also voice and video chat built in if you don't want to use an extra system like Discord

My groups vary from Owlbear Rodeo to roll20 to Foundry to meatspace maps and minis, and DDB is the character sheet repository. Discord for chat with remote users, and Avrae communicates the rolls.

Thanks to this thread I'll be giving AboveVTT a go.

D&D Beyond for character sheets, as well as the encounter builder for combat.  Zoom for face to face video chat, with an overhead camera looking at a corporeal map using miniatures when in combat or a puzzle where the special placing of objects or characters is an important part of the puzzle. Theatre of the mind for everything else.

I just use it as a rule’s reference since we play face to face. It’s much easier to carry an iPad than a whole stack of books. 

Feeling like the odd man out but we play in person with a battle mat that I draw on with miniatures.

We use DDB at the table. It is really easy for my players to keep track of their characters from the DDB app. We do not use VTT or Roll20, but rather battle mats from Chessex and Battle maps made in Inkarnate and printed out on paper.

 I did that pre-COVID.  Then I moved (twice) and am far away from the folks I played with.  I'm not aware of many players in this community.  So my games all require using internet based options to play.  If I were running in person games again, I would probably still use the encounters tool to run games, and use my Dropbox paper notes, etc.  But I'd use a battlemap and minis/pawns instead of a VTT.

DDB for character sheets and rulebooks (don't own any physical).

Foundry VTT for table top / battle maps.

Beyond20 to link them. 

Discord for voice and sharing links/documents.

D&D Beyond for character sheets and campaign overview with Beyond 20 to show quick party stats (as the DM).  Linked to Roll20 VTT for easy integration and great API's.  Go To Meeting for voice/video chat.  

If I'm the Quartermaster for the group, I take notes in Word.  If I'm the DM, I use Twine as a quick reference to the material I need efficiently.

I think a lot of folks forget that DDB was designed as something people would bring to physical tables.  Even the Encounter Builder and Combat tracker, people clamored to port those over to VTTs or see a VTT made, but really those things were intially supposed to be on a screen behind the DMs screen.  

I used to play pen & paper years ago and now that my family & friends live all over the US I am looking at starting up again via D&D Beyond + a VTT. I have added AboveVTT as a chrome extension, but I cannot figure out how to use it.  All of the YouTube guides that I have found are based on a very different version of AboveVTT, so not really useful. On a related note, I do not see a way to integrate premade campaigns using AboveVTT (either the free ones or a purchased one).  Any help would be greatly appreciated!

for maps and stuff you have to have them out on web somewhere you can share them like Google drive, Dropbox or Onedrive for encounters if they are prebuilt you can import them  but it takes some finessing them into above VTT. Your best bet for Free VTT's are owlbear rodeo or Roll20 as they are free with the possibility  for expansion into a paid service.  You could also look at  The Foundry.  Finally for a free version  but one with a huge learning Curve is  Maptools.  There are several 5e frameworks   to choose from
