is there a website to play dnd?

If you want to start tonight with nothing to install

Roll20 is a browser-based virtual tabletop with dice, character sheets, maps and ready-to-play adventures. There are no downloads, no hosting and no setup: you invite friends with a link. It says it supports D&D and 1,200+ other game systems, and its free tier is available forever, for GMs and players, with no credit card.

The catch is on the paid side. Its full API for automation needs a Pro subscription, and Roll20's subscription page blocked our request, so we cannot tell you what its paid plans cost.

If you want the simplest map table

Owlbear Rodeo is a lightweight browser tabletop focused on maps, fog, drawing and grid tools, with extensions for more. It says it runs as easily on mobile as on desktop, which helps if some of your group play from phones. It runs in the browser, on a phone as well as a computer.

The free Nestling plan is limited to 200MB of storage and up to 2 rooms, which suits one table and gets tight with several. Fledgling is US$3.99 shown, or US$3.33 a month billed yearly, and Bestling US$7.99, or US$6.66 a month billed yearly.

If your characters already live on D&D Beyond

D&D Beyond pairs the official site's character builder with its Maps virtual tabletop, so you play with official D&D books and characters you already keep there. A free account holds up to 6 character slots, lets you invite friends and lets you run games on the Maps VTT. Paid tiers add unlimited slots and Maps components: Hero from US$2.17 a month billed annually or US$2.99 monthly, and Master from US$4.58 or US$5.99 a month.

What you give up on the free tier is flexibility. Uploading custom maps and using homebrew monsters on Maps need the Master Tier.

If you hate subscriptions

Foundry Virtual Tabletop is self-hosted software: the GM runs a game server and players connect for free through a web browser. It is a one-time US$50.00 licence, perpetual, with future updates and no subscription fees or feature gating. Tax is computed at checkout.

The price of that is setup. You host it yourself on Windows, Mac or Linux, which takes more work than a website, in exchange for owning the data and paying once.

If you want the rules automated

Fantasy Grounds is a downloadable tabletop with automation for combat, initiative, attacks, saves, damage and effects. The full app is completely free, on Windows, Mac and Linux, and anyone can host games with no licences needed. If you would rather not do the arithmetic mid-fight, that is the draw.

The cost is that it is an install rather than a website, and official books and adventures are sold in its store.

When paying is worth it

Pay when the free tier limits your table. On Owlbear Rodeo that means more than 2 rooms or 200MB: Fledgling gives 5GB and up to 10 rooms, Bestling 10GB and up to 25 rooms. On D&D Beyond it is when you want custom maps, which means Master from US$4.58 a month billed annually, before tax; Master also lets you share purchased content with friends.

On Foundry, only the GM pays, once. Roll20's free tier covers GMs and players, and its Pro subscription adds the automation API.

D&D Beyond prices exclude taxes, and its subscriptions renew automatically, with cancellation taking effect at the end of the term. If you mean to stop, cancel before the renewal date.

Fantasy Grounds is free to play, but books and adventures are sold in its store; the free rulesets and SRD content come built in, so you can start without buying anything.

Roll20's advanced automation API needs a Pro subscription. If you only want dice, maps and sheets, that limit may not touch you.
