About
200+ Legacy Codebases Dataset
Description
The 200+ Legacy Codebases Dataset is a comprehensive collection of 200+ legacy software codebases spanning 11 industries, comprising 90.85M+ lines of source code and 455K+ source code files. Designed for AI/ML, foundation model training, software engineering, code intelligence, and application modernization, this dataset provides diverse real-world legacy code for developing and evaluating intelligent software development tools.
The dataset supports a wide range of AI applications, including code generation, code completion, code summarization, code migration, automated refactoring, software maintenance, technical debt analysis, bug detection, program comprehension, and legacy application modernization. It is an ideal resource for AI researchers, software engineering teams, and organizations building next-generation coding assistants and foundation models.
Note: The listed price applies to the specified initial batch of 2 million lines of code. Pricing for larger batches or the complete dataset library varies depending on the number of code repositories, total lines of code, programming language coverage, code complexity, metadata availability, annotation requirements, file formats, licensing terms, and customization needs. Final pricing will be determined based on the specific dataset requirements.
