Hi, we're Kevin, Chris, and Brian, the creators of JACoB (Just Another Coding Bot), an open-source AI coding agent designed to streamline the development process. As veteran developers, we know that while AI isn't perfect, it can be a valuable tool for tasks like code reviews, converting designs to React components, and writing high-quality GitHub issues. We’ve been building JACoB over the past year to assist with our real work, and today we’re open sourcing it under an Apache 2.0 license. Our goal is to create the first fully open-source tool that matches the quality and polish of many closed-source alternatives.<p>JACoB focuses on specific, time-consuming tasks that AI handles well, like generating code from Figma designs, fixing simple bugs, and writing boilerplate code like API endpoints. You can even converse with JACoB to refine existing GitHub issues or help write new ones. It integrates seamlessly into your workflow, from GitHub issues to pull requests, ensuring all code passes tests before finalizing.<p>JACoB is available on GitHub today, where you can customize it to your needs, such as running with local models. We're also developing a hosted version - sign up for the waitlist at <a href="https://jacb.ai" rel="nofollow">https://jacb.ai</a>. Currently, JACoB works best with JavaScript or TypeScript projects, especially with frameworks like Next.js.<p>To evaluate JACoB’s real-world abilities, we created our own benchmark arena since none existed for design-to-code tools. JACoB outperformed eight popular tools and human-written code, scoring an ELO of 1183, over 100 points higher than the nearest competitor. More details on how we achieved this are available in the technical whitepaper found in the repo.<p>AI is transforming software development, and we believe developers should lead this change, not large corporations. JACoB is our contribution to that future, respecting your privacy and security while remaining transparent and open.
We'd love your feedback.
