To use Second, developers can select from available modules to migrate or upgrade codebases. The A.I. agents then generate pull requests on GitHub, Bitbucket, or Gitlab, allowing developers to review and merge the changes.
To use Line0, describe your desired backend functionality in natural language. The AI will handle the implementation. You can use 'Tab' to autocomplete prompts or 'Enhance' for more detailed instructions. Connect your GitHub account for seamless 2-way synchronization of generated code. For testing, a built-in API client (coming soon) will allow direct in-browser testing of newly generated APIs with zero setup and hot reloads.
