OpenAI (P-OPEA) announced on March 19, 2026, that it will acquire Astral, the developer of open-source Python tools uv, ruff, and ty. Astral’s engineering team will join OpenAI’s Codex AI coding assistant to accelerate its development and expand AI integration across the software lifecycle.
Astral Integrates With Codex to Enhance AI Coding
OpenAI reached an agreement to acquire Astral, whose Python tools include uv, a package manager; ruff, a linter and formatter; and ty, a type checker. Astral’s engineers will join the Codex team, which supports more than 2 million weekly users. The acquisition aims to speed Codex’s development and broaden AI applications throughout software development.
OpenAI committed to maintaining Astral’s open-source projects after the deal closes, ensuring those tools remain available to developers even as engineering efforts shift toward product integration.
Strategic Move Amid Competition and Pending Approval
The acquisition strengthens OpenAI’s developer offerings and sharpens competition with rivals such as Anthropic by folding specialized Python tooling and engineering talent into Codex’s roadmap. Astral previously raised a Series A round led by Accel and a Series B led by Andreessen Horowitz following a 2023 seed round.
Financial terms were not disclosed. The transaction is subject to regulatory approval. This deal adds open-source tooling and engineering depth to Codex, highlighting the intensifying race among AI providers to embed coding workflows into their platforms.
