Major changes are coming to the Wiki! To learn more and let your voice be heard, please go here.
Additionally, we are currently experiencing some bugs and glitches. We're working on fixing them, but please be aware this means certain images, such as the collection grid for items, will be replaced by errors for the time being.
The debug console is accessible in The Binding of Isaac: Afterbirth †. It is an extremely useful way to verify a particular game mechanic, explore a seed, or test various things about the game. If you are a mod developer, you can use it to quickly test various things in your mods.
The debug console is only accessible if one or more mods are enabled. If you don't have any mods to enable, download one from Steam Workshop, or simply create an empty folder in your mods directory. (By default, the mods directory is located at "C:\Users\[username]\Documents\My Games\Binding of Isaac Afterbirth+ Mods".)
While many "enable debug console" mods exist on Steam Workshop, these do not explicitly enable the console or are required to enable it. ANY mod will enable the console, regardless of what the mod is named.
Using the Debug Console[edit | edit source]
To open the console, press the grave/tilde (~) key while in a run, or one of the keys matching key keyboard below.
|English||QWERTY||` or ~|
To hide the console, hit Enter without typing anything or Esc.
Pressing the up arrow key will bring up the last command used.

Trivia[edit | edit source]
- Stage 13 is the only non-standard stage that does not crash. It consists of 2x1 vertical rooms that have doors that only sometimes close, minimal enemies (usually 2 of the same type), and uses the Caves background. The music is a single layer of either the Blue Womb, the Cellar, or the Burning Basement music, and only plays when enemies are in the room. The boss is always The Duke of Flies, and no trapdoor or items spawn when the boss is defeated.
- Stage 13a is the same, but with the Depths background. The boss is always Monstro II.
- Stage 13b is the same, but with the Womb background. The boss is always The Duke of Flies.
- Any variant beyond 13b is the same as stage 13.
- The enemy spawn patterns are the same as the waves in Greed mode, suggesting that this stage is used to store the waves in the game.
- Entering "stage 8" in Greed or Greedier mode will grant access to The Void. The rooms have random backdrops and the music is the same as The Void in regular mode, but the boss is Ultra Greed and will drop the Final Boss Chest. Entering the chest will play the final ending instead of End 18 or 19.
- Attempting to give yourself all the items using "giveitem *" will print the message "What are you trying to do?" to the console.
