Save time when mapping systems relationships — and quickly digest how people, objects, places, and concepts are connected.
All you need in one shared space
Don’t waste time looking for information in different places and tools. Use our ERD creator to have a great overview of your system and a starting point for your database design improvements. With Miro's infinite canvas, draw concepts and solutions all in one place, keeping everyone in the loop.
No more back and forth
Say goodbye to context switching with Miro’s built-in ER diagram maker. Draw an ER diagram online without any friction, fetching your system information directly from your code. Collaborate with others by inviting them to your board, and have more time to discuss things that matter.
