MC Circle vs SeedLander

MC Circle is a web planner for Minecraft players who need block-by-block layouts for circular and curved builds. It generates charts for circles, ovals, half circles, and domes, with outline or filled views and optional grid lines. Numbered rows and columns guide block placement, while block counts and stack estimates support material planning. The main generator accepts sizes from 3 to 128 blocks and states support for Java and Bedrock editions. Plans can be downloaded as PNG files, copied as charts, or shared through links. The site also provides sphere plans with hollow or solid modes, layer counts, and per-layer block plans. Its coordinate output and layer-by-layer view help translate designs into builds. MC Circle runs in a browser without login, registration, payment, or subscriptions. The free plan is listed at free.

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.
