In their own words
BlockBlend
BlockBlend is a free browser tool for making Minecraft block palettes and geometric build blueprints. Its Circle Generator creates circles, rings, spheres, domes, and cylinders, with block counts, bounding-box information, and layer-by-layer views. Outputs include WorldEdit commands, ASCII blueprints, and JSON. The CraftLab palette library contains more than 300 blocks and can generate combinations around moods such as Medieval, Cyberpunk, Fantasy, and Oceanic. Palettes can be previewed in 3D, shared with the community, and exported as weighted WorldEdit //set commands. The Free plan is listed at free and includes unlimited palettes, all blocks, WorldEdit export, and community sharing. Image-to-palette conversion, schematic import, and map art are marked as coming soon.

SeedLander
SeedLander is a browser-based toolkit for analysing Minecraft seeds in Java Edition and Bedrock Edition, including Java Large Biomes. Its tools cover biome maps, structure searches, ore predictions, slime chunk calculations, portal management, and team collaboration. The structure finder covers 25+ types and provides coordinates for places such as villages, strongholds, temples, mansions, and monuments. SeedLander states that most structure results on Java and Bedrock are 97%+ accurate, while cautioning that they are predictions rather than guarantees. The tools run in the browser using WebAssembly, and seeds are not sent to SeedLander servers for processing. Map, finder, and account pages support touch use on phones and tablets; a dedicated mobile app is on the roadmap. The free Basic plan includes all seed tools, 10 custom markers, and three saved portal pairs. Premium costs £1.99 per month per world and adds unlimited markers and portals, ore tracking, structure completion tracking, notes, and an activity log. A Team add-on costs £2.99 per month per world on top of Premium.
