Find every Lava Pool on your Minecraft seed — Java 26.2 & Bedrock 1.26.40, any seed, free, no sign-up.
Quick answer: Lava Pools are pockets of open lava — at the surface and in flooded caves — that give quick access to lava for fuel, obsidian and Nether portals. This finder marks lava pools at a measured 90% accuracy on Java and 94% on Bedrock; the two figures cover different pool kinds — underground pools on Java, surface pools on Bedrock — because the editions generate them differently. Lava-flooded cave markers publish their own measured Java figure on the marker, and are still an estimate on Bedrock.
Open lava generates as small surface pools in many Overworld biomes and as larger lakes and flooded caves underground, especially near the deepslate layers. The finder marks the likely pockets so you can grab lava without spelunking blind.
Enter your seed and the finder marks lava-pool locations. Open a marker for coordinates and travel there with a bucket (and care). Surface pools are the easiest to reach; the larger underground lakes sit nearer diamond depth.
A nearby lava source is one of the most useful early finds: a bucket of lava is long-lasting furnace fuel, lava plus water casts the obsidian for a Nether portal, and a surface pool saves a deep, dangerous dig for your first portal.
Yes — both editions, Minecraft 26.2 (Java) and 1.26.40 (Bedrock). Lava-pool markers are block-verified against real generated worlds on both: a measured 90% on Java and 94% on Bedrock. The two numbers describe different pools, and we would rather say so than average them: on Java the figure covers the underground pools the cave generator leaves behind, while on Bedrock it covers the surface pools that generate in the open — each edition's own generator places a different kind, so each figure prices what that edition actually puts at the marker. Lava-flooded cave markers carry their own measured Java figure, shown on the marker itself — it means a real cave with exposed lava is there — and are still published as an estimate on Bedrock while that measurement is pending.
