In the modern programming landscape, very few individuals have shaped the developer experience as profoundly as Will McGugan. Known primarily for his work on the Python libraries Rich and Textual, he has transformed how developers interact with command-line interfaces and how they design terminal-based applications. With a career spanning software engineering, open-source leadership, technical innovation, and entrepreneurial exploration, Will McGugan has become a respected voice in the global tech community.
Early Career and Background
Will McGugan’s journey into the world of software engineering began long before he became a recognised name in Python circles. Coming from a background deeply rooted in programming and problem-solving, he spent years experimenting with system design, file-handling interfaces, and performance optimisation. His curiosity and passion for creating elegant developer experiences eventually paved the way for his most notable projects.
Before gaining mainstream attention, he worked on PyFilesystem, a library that unified the way Python applications interact with different types of storage systems. This project showcased his natural ability to simplify complex development challenges through well-designed abstractions. Even at this early stage, the patterns and philosophies that would later define his more famous work were already visible—clean design, intuitive interfaces, and developer-centred functionality.
The Rise of Rich: A New Era for Terminal Output
The Python library Rich became Will McGugan’s breakthrough contribution to the global developer community. Prior to Rich, terminal output was often plain, hard to read, and limited in visual expression. Rich changed that entirely by bringing colour, formatting, syntax highlighting, tables, progress bars, markdown rendering, and advanced styling features to the command line.
Why Rich Became So Popular
Developers embraced Rich for several key reasons:
- It made terminal output visually appealing without adding complexity.
- The library was built with performance and readability in mind.
- It enabled developers to turn ordinary CLI tools into polished, professional utilities.
- Documentation and API design were structured to feel natural even for beginners.
Rich grew rapidly in popularity across the Python ecosystem, becoming the default choice for engineers building modern CLI tools, DevOps workflows, testing utilities, and logging systems. Developers praised its clarity, while companies integrated it into production-grade applications due to its reliability and performance.
The Birth of Textual: Reinventing the Terminal User Interface
After the success of Rich, Will McGugan turned his attention to an even bigger challenge—designing a framework that would allow developers to build interactive user interfaces directly inside the terminal. This led to the creation of Textual, a groundbreaking Python framework that brought reactive UI programming to the terminal world.
What Makes Textual Revolutionary
Textual is built upon several innovative principles:
- It allows developers to design layouts, widgets, and animations using a responsive model similar to frontend web development.
- Interfaces built with Textual feel modern, dynamic, and extremely fast.
- It reduces the barrier to entry for creating functional UIs without relying on traditional GUI frameworks.
- Applications can run both in the terminal and optionally in the browser, offering flexibility and accessibility.
By abstracting away the complexity typically associated with terminal-based user interfaces, Textual unlocked new possibilities for internal tooling, dashboards, monitoring applications, and lightweight productivity software.
Founding Textualize: Turning Innovation into a Venture
With Rich and Textual gaining global adoption, Will McGugan took the natural next step—founding Textualize, a company aimed at supporting and expanding the future of terminal-based software. The goal was to create a sustainable structure around the development of these libraries while exploring new ways to combine terminal design with modern application experiences.
Textualize attracted attention for its forward-thinking vision: blending traditional command-line workflows with highly interactive, visually rich interfaces. Developers saw it as a refreshing alternative to the heavy, complex frameworks used for both frontend and backend applications.
Although Textualize began as a promising venture, Will McGugan eventually entered a period of reflection, considering new directions for his personal and professional life. His public writings reveal a thoughtful, grounded approach—balancing ambition with health, creativity, and long-term sustainability.
Philosophy of Engineering and Design
Will McGugan is known not just for his code, but for his philosophy. Several core beliefs consistently surface in his talks, interviews, and writings.
Developers Deserve Beautiful Tools
Across his projects, one message remains clear: tools matter, and developers deserve interfaces that make them feel capable and confident. Rich and Textual are both expressions of this belief, turning plain text into something visually meaningful.
Quality and Stability Come First
He often emphasises that developers do not want surprises, especially when working with libraries they depend on. Stability, thoughtful API design, and backward compatibility are values he prioritises carefully.
Innovation Should Reduce Complexity
Rather than creating tools that require steep learning curves, his approach focuses on simplicity. His libraries are powerful but still easy to grasp, which explains why they spread so quickly through the community.
Creativity in Tech Matters
While many view programming as purely logical, Will McGugan considers it a creative discipline. He encourages developers to enjoy the craft, experiment, and approach problems with curiosity. His own work showcases this mindset: visually rich interfaces, elegant abstractions, and expressive design.
Influence on the Python Community
The impact of Will McGugan’s work on the Python ecosystem cannot be overstated. His libraries are used in countless open-source projects, enterprise tools, educational materials, and internal systems. They have become staples for:
- DevOps pipelines
- Logging frameworks
- Productivity tools
- Monitoring dashboards
- Testing suites
- Teaching materials for computer science students
- Command-line utilities across multiple industries
His contributions have elevated the expectations of what terminal applications can look like and how they can behave. In doing so, he uplifted the overall Python developer experience, making tasks more enjoyable, readable, and accessible.
Personal Writing and Public Thoughts
Beyond coding, Will McGugan is also an articulate writer. His essays provide insight into the emotional and philosophical aspects of being a long-term open-source maintainer. He writes about burnout, ambition, sabbaticals, future planning, and the delicate balance between building tools for the world and taking care of oneself.
His openness resonates strongly with developers who face similar pressures, especially those juggling full-time work with open-source commitments.
The Project “Toad” and Future Direction
In recent notes, Will McGugan mentioned working on a new project called “Toad”. Early hints describe it as a universal interface for agentic coding within the terminal environment. While still in early stages, this project suggests his ongoing interest in blending automation, AI-assisted workflows, and terminal design into something novel.
Regardless of how Toed evolves, it demonstrates that he continues to explore fresh ideas and push boundaries in developer tooling.
Lessons Developers Can Learn from Will McGugan
Both beginner and expert developers can take valuable lessons from Will McGugan’s journey.
Focus on User Experience
Even when designing tools for technical users, UX matters. Rich and Textual succeeded because they made complex tasks delightful.
