About Us

Welcome to Umamusume.run

Umamusume.run is a fan-operated planning site for Umamusume: Pretty Derby players. We specialize in tools that help you compare support decks, training setups, databases, and guides before you spend time on a run.

Our Mission

Our mission is to help Umamusume trainers make clearer gameplay decisions and save valuable time. We focus on:

  • Developing tools that solve real gameplay-planning challenges
  • Helping players compare team-building and training strategies
  • Maintaining comprehensive, searchable databases with direct tool handoffs
  • Creating guides based on available game mechanics and statistics
  • Helping F2P players make more deliberate resource decisions

What We Offer

🔥 Deck Builder

Support-card recommendation tool for comparing available cards and target strategies.

📊 Training Simulator

Training estimator that shows likely stat ranges before training, helping you decide whether a setup is worth testing.

🧬 Legacy Calculator

Calculate inheritance stats and compare factor combinations for breeding plans.

📚 Character Database

Comprehensive database with search, filters, and direct links to planning tools for each character.

🎴 Support Card Database

All support cards with synergy analysis, tier rankings, and one-click integration with the Deck Builder.

🏆 Strategic Guides

Guides focused on planning strategies, stat requirements, and competitive team building.

Server Coverage

We provide comprehensive coverage for both game servers:

  • Japan Server: Launched in 2021, featuring the complete game experience with all characters, events, and features
  • Global Server: Launched in June 2024, gradually catching up with content releases tailored for the international audience

Our guides and resources clearly indicate which server they apply to, ensuring you get relevant information for your version of the game.

Why Choose Our Tools?

Unlike static spreadsheets or generic guides, our tools start from your selected cards and goals. We focus on practical problems:

  • Can't beat Champions Meeting? Deck Builder suggests teams to test from your collection
  • Not hitting stat targets? Training Simulator estimates outcomes before you spend stamina
  • Need blue factors? Legacy Calculator shows thresholds and probabilities
  • F2P struggling? Tools help compare limited-resource options

Important Note: We are an independent fan website and are NOT affiliated with Cygames, Inc., the r/UmaMusume subreddit, or any official Umamusume social media accounts. All game content and assets belong to their respective owners.
