Tech Tree Generator

What is a Tech Tree?

A tech tree (technology tree) is a hierarchical diagram showing how technologies, skills, or knowledge areas relate to and build upon each other. Originally popularized by strategy games like Civilization and Age of Empires, tech trees are now widely used in education, game design, project management, and career planning.

Common Uses for Tech Trees

• Game Development — Design skill trees, talent systems, and research progressions for RPGs, strategy games, and mobile games
• Education — Create learning paths showing prerequisite knowledge and skill progression
• Career Planning — Map out career progression from junior to senior roles with required skills
• Project Management — Visualize feature dependencies and development roadmaps
• World-Building — Design technology evolution for fiction, TTRPG campaigns, or creative projects

Skill Tree vs Tech Tree

While often used interchangeably, skill trees typically represent character abilities in games (think RPG talent trees), while tech trees represent broader technological or knowledge progressions. This generator supports both — use it for game skill trees, learning paths, or any hierarchical progression system.
