No Block Left Behind
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
What is No Block Left Behind?
No Block Left Behind adds over 100 new blocks to Minecraft, that fill in the gaps in Minecraft's building blocks. From chiseled calcite to red terracotta walls, it adds a new array of things for you to build with. It fits in seamlessly with Minecraft's creative menu. No extra creative tabs here. It's like it was a real block all along. This mod is still in beta so there's way more to come. If you have suggestions post them on the GitHub page.
