OpenAI to acquire Pierre, maker of Code Storage and Codex's Trees and Diffs
OpenAI announced that it will acquire Pierre Computer Company, Inc. ("Pierre"), the company behind Code Storage and a family of open-source developer tools. The deal has not closed. It is subject to customary closing conditions, including regulatory approvals, and until then OpenAI and Pierre remain separate and independent companies.
OpenAI's announcement says that anyone who has browsed files or reviewed a change in the Codex app has already used Pierre's Trees and Diffs libraries. Trees lets developers quickly navigate a project's files, and Diffs makes it easy to see what changed. OpenAI says both make it easy to review and navigate large volumes of code with "uncompromising performance".
OpenAI also points to Pierre's other work. Diffs has an Edit mode that lets a reviewer fix a line of code right where the problem is spotted. Pierre recently released Highlights, which OpenAI describes as an extremely fast syntax highlighter that updates as a developer types or an agent streams code. The same small team designed the API for Code Storage, a service that lets apps store code and track its history using Git.
The stated rationale is about Git and coding agents. OpenAI says it has seen in its own engineering work that the systems around Git need to evolve as more work happens in parallel, and notes that earlier the same week it shared how it is scaling Git with Pando, its in-house source control backend for engineers and agents. With the Pierre team, OpenAI says it wants to build on the Git workflows developers already rely on and adapt them to how teams work with coding agents, and to "set the standard for modern software development: from the first branch an agent creates to that magic moment when code is deployed to the world". It wants Codex to be the place where developers and agents take on their most ambitious projects, and to connect the code a company ships with the decisions its people make.
Once the deal closes, OpenAI's stated ambition is to advance the future of source control across the industry. For existing users, the announcement makes two commitments: Pierre's open-source projects will remain open-source and OpenAI will keep contributing to them, and customers can continue using Code Storage after closing while OpenAI works to bring its features and functionality into Codex.
The announcement gives no price or deal terms, no closing date, and no names of Pierre's founders or staff.
Key facts
- OpenAI will acquire Pierre Computer Company, Inc., the company behind Code Storage and a family of open-source developer tools.
- Pierre's Trees (file navigation) and Diffs (change review) libraries are already used in the Codex app; Pierre also recently released the Highlights syntax highlighter.
- OpenAI says Pierre's open-source projects will stay open-source, and that Code Storage customers can keep using it after closing while its features are brought into Codex.
- Closing is subject to customary conditions including regulatory approvals; until then the two companies remain separate and independent.
- No price, closing date or timescale for the Codex integration is given.
Why it matters
The deal ties OpenAI's coding product more closely to source control. OpenAI frames it as a response to Git workflows strained by agents working in parallel, and links it to Pando, the in-house source control backend it described earlier the same week. Its stated goal is to cover the path from the first branch an agent creates to deployed code, with Codex as the central place for that work. The announcement also says it hopes to advance the future of source control across the industry once the deal closes.
Who it affects
Codex users already rely on Pierre's code: file browsing and change review in the Codex app use the Trees and Diffs libraries. Customers of Code Storage, the service for storing code and tracking its history with Git, are told they can keep using it after closing. Developers who use or contribute to Pierre's open-source projects are told those projects will remain open-source.
How to use it
There is nothing new to adopt yet, since the deal has not closed. Code Storage customers can carry on as they are; OpenAI says it will bring the service's features and functionality into Codex over time, with no timescale given. Codex users already get the Trees and Diffs libraries. Diffs has an Edit mode that lets a reviewer fix a line right where the problem is spotted, though the announcement does not say that Codex exposes this mode to users. Pierre's recently released Highlights, a syntax highlighter that updates as a developer types or an agent streams code, is among the open-source tools the announcement describes.
How solid is it
This is OpenAI's own first-party announcement, so the facts about the deal and the products come from the acquirer. The announcement states that the acquisition will happen but also that it is not complete. Descriptions such as "extremely fast" and "uncompromising performance" are OpenAI's characterisations, not independent measurements. The announcement contains no quoted statements from named individuals at OpenAI or Pierre.
Risks and caveats
The deal is subject to customary closing conditions, including regulatory approvals, and no closing date is given. No purchase price or deal terms are disclosed. The promise that open-source projects stay open-source and that Code Storage customers can keep using it is tied to the period after closing while features move into Codex; the announcement does not say whether Code Storage will be discontinued or continue as a standalone product after that integration. No figures on Code Storage customers, revenue or usage are given.
“Pierre’s open-source projects will remain open-source, and we’ll continue to contribute to them.”
