OpenAI to acquire Pierre Computer Company, Inc.
OpenAI announced on November 4, 2026 that it will acquire Pierre Computer Company, Inc., the company behind Code Storage and a family of standout open-source developer tools. The acquisition is intended to expand Codex’s tools for building, understanding, and reviewing code.
OpenAI said that people who have browsed files or reviewed a change in the Codex app have already used Pierre’s Trees and Diffs libraries. The company said it wants to work with the Pierre team to build on the Git workflows that developers already rely on and adapt them to how teams work with coding agents.
Pierre’s tools and Code Storage
OpenAI said it has long appreciated the care Pierre brings to how developers review code. Trees lets developers quickly navigate a project’s files, and Diffs makes it easy to see what changed. Both tools make it easy to review and navigate large volumes of code with uncompromising performance.
Diffs’ Edit mode lets a reviewer fix a line of code right where they spot the problem. Pierre recently released Highlights, an extremely fast syntax highlighter that updates as a developer types or an agent streams code. The same small team that put an editor inside a diff also designed the API for Code Storage, a service that lets apps store code and track its history using Git.
Plans after the acquisition closes
Once the acquisition closes, OpenAI’s ambition is to advance the future of source control across the industry. The company wants Codex to connect the code a company ships with the decisions its people make, at the scale the future demands.
Pierre’s open-source projects will remain open-source, and OpenAI will continue to contribute to them. Customers can continue using Code Storage after the acquisition closes while OpenAI works to bring its features and functionality into Codex.
The closing of the acquisition is subject to customary closing conditions, including receipt of regulatory approvals. Until closing, OpenAI and Pierre will remain separate and independent companies.
