From College Roommates to Tech Innovators: The Story of Gauge

Gauge is an innovative start-up founded in 2024 in San Francisco, tackling a significant and often perplexing issue in software development: the choice between monolithic and microservices architecture. With a small but highly capable team of two, led by CEO Caelean Barnes and CTO Evan Doyle, Gauge has introduced groundbreaking open-source Python tools designed to enable teams to build and scale a modular monolith. This unique approach offers a middle ground, capturing the simplicity of monolithic architecture while harnessing the scalability advantages of microservices.

Gauge’s mission is to provide developers with tools that streamline and simplify the architectural complexity associated with growing codebases. Their first tool, Tach, is already making waves in the development community, and their long-term vision promises to transform how applications are deployed and scaled.

How Did Gauge Come to Be?

The origins of Gauge can be traced back to a college dorm room where Caelean Barnes and Evan Doyle first met as roommates. Over the past decade, both have dedicated their careers to the startup ecosystem, assuming multiple founding engineering roles and helping several startups grow from inception to success. Throughout their professional journey, they encountered a recurring challenge: maintaining development velocity as startups scaled. The monolith vs. microservices dilemma was a constant source of frustration, often leading to significant inefficiencies and technical debt.

Driven by these shared experiences and a desire to create a better solution, Caelean and Evan founded Gauge. They set out to develop tools that would allow teams to benefit from both monolithic and microservices architectures without the associated pitfalls. Their combined expertise and firsthand experience with the problem uniquely positioned them to tackle this challenge head-on.

What is the Microservices/Monolith Dilemma?

In the fast-paced world of startups, speed is often prioritized over code quality. This necessity for rapid development can lead to code sprawl and tightly coupled services, creating what developers refer to as a "ball of mud." As codebases grow, introducing new features or refactoring existing ones becomes increasingly difficult. At this juncture, many startups turn to microservices as a solution, hoping to break down their applications into smaller, independently deployable services.

However, the transition to microservices is not a panacea. It introduces a new set of complexities, including service orchestration, lifecycle management, and dependency versioning. The initial problem of a monolithic codebase morphs into a different, but equally challenging, set of issues. This dilemma leaves many development teams stuck between choosing a monolithic architecture, which can become unwieldy, or microservices, which can become overly complex.

How Does Gauge Address This Problem?

Gauge offers a novel solution by promoting the concept of a modular monolith. Instead of completely transitioning to microservices, Gauge enables teams to break down a monolithic codebase into decoupled modules with well-defined interfaces. This approach provides the benefits of microservices—such as improved maintainability and scalability—without the accompanying complexity.

The flagship tool from Gauge, Tach, plays a pivotal role in this process. Tach automatically creates module boundaries within a monolithic codebase, facilitating the modularization process. Written in Rust, Tach is designed for speed and efficiency, ensuring minimal runtime impact on applications. This tool is not only theoretically sound but also practically effective, as evidenced by its adoption in production environments by several companies. Tach has achieved over 100,000 downloads and garnered more than 500 stars on GitHub, highlighting its popularity and reliability.

What Makes Tach Stand Out?

Tach distinguishes itself through several key features. First and foremost, it is incrementally adoptable, allowing teams to modularize their codebase at their own pace. This flexibility is crucial for startups that need to balance development speed with long-term architectural improvements. Tach is also highly interoperable, integrating seamlessly with continuous integration (CI) systems, pre-commit hooks, file watchers, and VS Code extensions. This versatility ensures that Tach can be easily incorporated into existing development workflows.

Another standout aspect of Tach is its open-source nature. Gauge has made Tach available under a permissive license, ensuring that it is accessible to a wide audience. This commitment to open source not only fosters community collaboration but also allows developers to customize and extend Tach to meet their specific needs.

What are the Future Plans for Gauge?

Gauge has ambitious plans for the future, aimed at further enhancing their suite of tools to support the scaling of modular monoliths. In the short term, they are focusing on adding features such as architecture enforcement, intelligent cached task execution, and smart build and deployment pipelines. These enhancements will provide development teams with even more control and efficiency in managing their codebases.

Looking further ahead, Gauge envisions a revolutionary approach that allows for the deployment of a modular monolith as a set of independent services. This strategy aims to combine the best aspects of both monolithic and microservices architectures. By enabling a modular monolith to be deployed as independent services, Gauge plans to offer the scalability and fault tolerance of microservices while retaining the simplicity and coherence of a monolith. This forward-thinking approach is inspired by recent research and practices in leading tech companies, and Gauge aims to democratize these advanced deployment strategies for the broader industry.

Who are the Founders of Gauge?

Caelean Barnes, the CEO of Gauge, has a rich background in developing open-source tools for software development. Before founding Gauge, he held key engineering roles at Standard Metrics and Noble AI, and was an early team member at Carta and Roku. Caelean’s extensive experience in building scalable solutions for startups has been instrumental in shaping the vision and direction of Gauge.

Evan Doyle, the CTO of Gauge, brings a wealth of experience in technical consulting for early-stage startups. He has been a pivotal member of the engineering teams at Carta and Standard Metrics, where he gained valuable insights into the challenges of software architecture. Evan is passionate about open-source software and is dedicated to solving complex problems related to codebase management and scalability.

What is the Reception and Impact of Gauge's Tools?

The reception of Gauge’s tools, particularly Tach, has been overwhelmingly positive within the developer community. The significant number of downloads and GitHub stars are strong indicators of the tool’s utility and effectiveness. Companies that have adopted Tach in their production environments have reported substantial improvements in code maintainability and development efficiency. The positive feedback and widespread adoption underscore the importance and relevance of Gauge’s approach to solving the microservices/monolith dilemma.
