What the SRD bestiary is
The SRD (Systems Reference Document) is the open version of the D&D 5e rules, released by Wizards of the Coast under the Creative Commons CC-BY-4.0 license. That means anyone can use, translate, and distribute the SRD monsters, spells, and rules — us included. It is why the monster compendium in Pocket DM is 100% free and lives online for good.
We bring together the creatures from the SRD 5.1 (2014) and the SRD 5.2 (2024) — many are the same creature revised between editions — plus the 357 from Monster-a-Day (a partnership with the r/monsteraday subreddit), also under CC. That's 684 distinct browseable stat blocks, each with a full description, attacks, legendary actions where applicable, and a clean layout. Product-identity monsters like the Beholder and Mind Flayer are not part of the SRD, so you will not find them here.
Monsters by Challenge Rating (CR)
A common question from new DMs: which CR should I use for my party? Here is the shortcut — and if you want to fine-tune the balance, the encounter calculator runs the official DMG (2014 & 2024) formula for you.
Dragons
From wyrmlings to ancients, chromatic (evil) or metallic (good). Dragons have been iconic to D&D since the very first edition.
Undead
Skeletons for early encounters, liches for campaign finales. Vulnerable to radiant, immune to poison and to being charmed.
Humanoids
Versatile enemies: goblins, orcs, hobgoblins, bandits. They fit any level and any political or military campaign.
Beasts & Monstrosities
Giant spiders, owlbears, oozes. The random encounters of forests, dungeons, and caverns.
Iconic monsters to build a campaign around
Drop one of these on the table and your players will remember the session. You do not even have to kill anyone — the reveal alone does the work.

TarrasqueCR 30
The most iconic monster in D&D. An apocalyptic CR 30 creature that can level entire cities. Only one is said to exist — the perfect capstone for an end-of-the-world campaign.

LichCR 21
A wizard who cheated death by binding their soul to a phylactery. Immortal, patient, and always scheming something in schools of magic your players cannot yet imagine.
View stat block →

KrakenCR 23
One of the great ancient horrors of the oceans. Legendary, with tentacle and lightning attacks. Perfect for a seafaring campaign's climax.
View stat block →

Ancient Red DragonCR 24
The king of chromatic dragons. Greedy, arrogant, and armed with a fire breath that can roast a party in a single action.
View stat block →

Ancient Gold DragonCR 24
The noblest of metallic dragons. A powerful ally or a righteous final boss, with a breath weapon that weakens as much as it burns.
View stat block →

VampireCR 13
The classic gothic villain: charming, regenerating, and deadly at the head of a manor full of thralls. A whole campaign can orbit a single vampire lord.

How to use the bestiary in Pocket DM
Pocket DM is built to remove the biggest friction in combat: rolling attacks and saves. When you drop a monster into the combat tracker, every action becomes a clickable button. One click equals an automatic roll with the right modifier. Damage, saves, criticals — all there.
