Rubric Labs is an applied AI lab that specializes in developing AI-augmented solutions for companies by rapidly creating experimental proof-of-concept software and full-stack applications, with a particular emphasis on a developer-first experience. They favor modern, open-source development tools and have adopted Neon, a serverless Postgres database, for both internal and client projects due to its features like database branching, autoscaling, and a streamlined development workflow. This allows each developer to work in isolated environments, facilitating parallel testing and quick rollbacks. In addition to Neon, Rubric Labs employs a technology stack that includes Next.js for web development, TypeScript, Vercel for hosting, and Tailwind CSS for styling. They enhance their AI capabilities with tools like Vercel's AI SDK, LangChain, and models from Anthropic and OpenAI. Rubric Labs has also built internal tools like the Rubric Operating System and open-source projects such as SyncLinear, which syncs tickets between Linear and GitHub. They have a strong preference for tools that prioritize developer efficiency and offer solutions like Supabase for rapid iterations and PlanetScale for MySQL projects.
