OpenAI is acquiring Python developer toolmaker Astral, thus bringing open source developer tools into OpenAI’s Codex AI coding system. The acquisition was announced on March 19. Elaborating on the deal, OpenAI said Astral has built widely used open source Python tools, helping developers move faster with modern tools such as uv, Ruff, and ty. These tools power millions of developer workflows and have become part of the foundation of modern Python development, OpenAI said.

By bringing in Astral’s tools and engineering expertise, OpenAI said it will accelerate work on Codex and expand what AI can do across the software development life cycle. OpenAI’s goal with the Codex ecosystem is to move beyond AI that simply generates code and toward systems that can participate in the entire development workflow, helping plan changes, modify codebases, run tools, verify results, and maintain software over time. Astral’s developer tools sit in that workflow. With the integration of these systems with Codex, OpenAI said it will enable AI agents to work more directly with the tools developers already rely on every day.

Python, OpenAI said, has become one of the most important languages in modern software development, powering everything from AI and data science to back-end systems and developer infrastructure. Astral’s open source tools play a key role in that ecosystem, OpenAI said. These tools and their capabilities are cited in OpenAI’s announcement:

  • Uv simplifies dependency and environment management.
  • Ruff provides fast linting and formatting.
  • Ty helps enforce type safety across codebases.

Astral also offers pyx, a Python-native package registry now in beta. OpenAI said that by having Astral, OpenAI will continue to support these open source projects while exploring ways they can work more seamlessly with Codex to enable AI systems to operate across the full Python development workflow.

The closing of the acquisition is subject to customary closing conditions, including regulatory approval, OpenAI said. Until the closing, OpenAI and Astral will remain separate, independent companies. Deeper integrations will be explored that allow Codex to interact more directly with the tools developers already use, helping develop Codex into a true collaborator across the development life cycle, according to OpenAI.
