Ancient debris (netherite) peaks at Y 15, generating Y 8-24. Enter your seed and this Netherite Finder maps ancient debris at 91% accuracy on Java 26.3 and 85% on Bedrock 1.26.51 — best netherite level and where to find it, on a visual map.

Quick answer: Ancient debris (the source of netherite) peaks at Y 15 and generates between Y 8 and Y 119, densest from Y 8 to 24. This Netherite Finder marks ancient debris from your seed on a visual map at 91% accuracy on Java 26.3 and 85% on Bedrock 1.26.51.
| Edition | Version | Best Y level | Spawn range | Finder accuracy |
|---|---|---|---|---|
| Bedrock | 1.18 – 26.51 (current) | Y 15 | Y 8 to 119 | 85% |
| Java | 1.18 – 26.3 (current) | Y 15 | Y 8 to 119 | 91% |
Accuracy is the share of marked hotspots that really contain the ore in your world, shown as a plain number.
Ancient debris is most common at Y 15. It generates throughout the Nether from Y 8 up to Y 119, but the dense band is Y 8 to 24 — so the netherite level players mine at is Y 15 (sometimes Y 14–16 to clear a 2-block-tall tunnel). Netherite itself is crafted from the scrap you smelt from ancient debris.
Ancient debris spawns anywhere in the Nether, buried inside netherrack, basalt and blackstone — it is never exposed to air, so you have to dig or blast to it. It is blast-resistant, so bed or TNT mining at Y 15 is a common tactic. The finder marks the chunks most likely to hold a vein so you don't blast blind.
Y 15 works on Bedrock too, for a slightly different reason. Java bunches its deep debris around the middle of the Y 8 to 24 band; Bedrock spreads its deep debris evenly between about Y 8 and 23, so no level beats another there, and Y 15 sits in the middle of both. The tunnel plan is the same on either edition. The finder supports Bedrock 1.26.51 at 85% accuracy — the badge by the page title shows both editions' figures.
No — not in any version this finder covers. Ancient debris generates across Y 8 to 119 with its dense band at Y 8 to 24 on Java 1.18 through 26.3 and Bedrock 1.18 through 26.51, and Y 15 has been the level to tunnel at throughout. The debris generator is version-independent on both editions: across that whole span the same seed puts the same debris in the same place.
Yes — switch the edition above and the finder marks ancient debris on Bedrock 1.18 through 26.51 at 85% accuracy, against 91% on Java. Both editions share the Y 8 to 119 range and the Y 15 sweet spot, so the tunnel plan is identical; only the vein positions differ, because the two editions build the Nether from your seed differently.
