BeetleBox

BeetleBox is an offline combinatorics and planning workspace that helps you build valid combinations from a collection of items based on rules and constraints. Define your items, organize them into categories, set requirements and exclusions, and generate combinations that meet your criteria—all directly on your device. Whether you're planning outfits, creating game loadouts, organizing meal options, or exploring resource allocations, BeetleBox helps you work through structured selection problems without spreadsheets, accounts, or an internet connection. Key Features Item Pools & Categories – Organize items into categories and optionally assign weights. Use individual items or entire categories when creating rules. Flexible Rules & Constraints – Set required or excluded items, incompatible pairs, category minimums and maximums, weight limits, any-of conditions, and mutually exclusive groups. Contradiction Detection – Check your rules for conflicts before generation begins, helping you identify incompatible constraints early. Smart Combination Generation – Invalid possibilities are eliminated early during generation, while workload estimates help you understand the expected processing effort before starting. Results & Comparison – Browse generated combinations in an organized layout, save favorites, compare two to four combinations side by side, or generate a random valid combination. Saved Explorations – Save complete exploration projects and return to them whenever you want. Reusable Rule Sets – Create reusable collections of constraints and apply them to different item pools and planning scenarios. Flexible Planning for Different Needs Use BeetleBox to: Plan outfits from a wardrobe Build game character or deck combinations Create meal plans based on specific rules Explore resource allocation options Organize structured selections Find valid combinations from complex sets of constraints Private & Offline Everything runs locally using an on-device database. BeetleBox requires no account, no login, and no network connection. Your items, rules, explorations, and generated combinations stay on your device, with no data sent to external services. BeetleBox gives you a practical way to explore combinations, test constraints, and find valid selections wherever you need them—completely offline.
