Second

Second provides AI developer bots that work like real engineers — writing code, building features, and handling entire codebase migrations so your human developers can focus on what matters most. Whether you need to generate a new web application from scratch, add full-stack features to an existing one, or migrate legacy code to modern frameworks, Second's AI agents handle it end-to-end. They leverage OpenAI, Azure OpenAI, AWS Bedrock, and open-source models, and are controlled by purpose-built modules engineered for specific migration tasks — eliminating prompt drift and keeping things consistent. Second agents are experts in the latest versions of modern frameworks and libraries, interface directly with GitHub, Bitbucket, or GitLab via pull requests, and handle everything from dependency resolution to build system updates and test upgrades.
