About 5E Creature Codex
Your ultimate companion for Dungeons & Dragons 5th Edition creature reference and combat management
Our Mission
5E Creature Codex was created to provide Dungeon Masters and players with a fast, free, and accessible way to reference D&D 5E creatures during gameplay. We believe that better tools lead to better games, and everyone should have access to quality resources regardless of budget.

About the Creator
5E Creature Codex was created by NamuNinja, a developer and D&D enthusiast who saw the need for a better creature reference tool during game sessions.
After years of fumbling through physical books and PDFs during gameplay, the idea was born: create a fast, searchable, free tool that any DM could use without slowing down the game.
This project represents hundreds of hours of development, all done with love for the game and the community. The code is original work, while all creature content comes from the SRD 5.1 under the Open Game License.
