Optic

We help developers collaborate at scale and build better APIs. Optic’s open source tools makes it easy for developers to document API changes, review each other’s API changes during code review, and catch breaking changes before they reach production.

tl;dr It’s version control but for behavior not code. We are taking the really successful ideas from Git / Code Review / CI and applying them to API descriptions and (future) other non-code artifacts.

High-Level Overview

Optic is a developer-focused company that builds tools to make APIs more developer-friendly by simplifying API documentation, change tracking, and collaboration. Their open-source platform enables developers to document API changes automatically, review API modifications during code reviews, and catch breaking changes before deployment. This approach effectively applies version control principles to API behavior rather than just code, helping engineering teams build better, more reliable APIs at scale[3][4]. Optic primarily serves software developers and engineering organizations, improving API quality and developer productivity.

Origin Story

Founded in 2018 by Aidan Cunniffe, Optic emerged from the need to improve API collaboration and documentation workflows. The idea was to bring the successful practices of Git, code review, and continuous integration to API development, which traditionally lacked robust tooling for managing API changes. Early traction included adoption by engineering teams at companies like Snyk, validating the product’s value in real-world API development environments[3]. Optic was later acquired by Atlassian, where it is integrated into their developer experience platform Compass, amplifying its reach and impact[4].

Core Differentiators

• Product Differentiators: Optic automates API documentation and change tracking by integrating with developers’ existing workflows and CI pipelines, reducing manual effort and errors[3][4].
• Developer Experience: It offers a seamless experience for documenting API changes during code reviews, enabling teams to catch breaking changes early and maintain up-to-date API specs.
• Speed and Ease of Use: By leveraging OpenAPI specifications and automating detection of API changes, Optic accelerates API-first development and improves API stability.
• Community Ecosystem: As an open-source tool, Optic benefits from community contributions and adoption, fostering collaboration and continuous improvement[3].

Role in the Broader Tech Landscape

Optic rides the growing trend of API-first development and microservices architectures, where managing API complexity and consistency is critical. The timing is favorable as more organizations adopt distributed systems and require scalable tools to govern APIs effectively. Market forces such as the rise of DevOps, continuous integration, and the need for faster software delivery underpin Optic’s relevance. By integrating with platforms like Atlassian Compass, Optic influences the broader ecosystem by embedding API governance into developer workflows, promoting better software health and faster innovation[4].

Quick Take & Future Outlook

Looking ahead, Optic’s integration into Atlassian’s developer platform positions it to become a central tool for API governance across large engineering organizations. Trends such as increasing API complexity, demand for automation in software delivery, and the shift-left movement in testing and quality assurance will shape its evolution. Optic’s influence is likely to grow as it helps teams maintain API quality at scale, enabling faster and more reliable software development. Its open-source roots combined with enterprise integration provide a strong foundation for sustained impact in the API tooling space[4][3].
