Elon Musk Announces Full Open Source Release of X's Codebase After Security Review

On July 15, 2026, Elon Musk announced that X (formerly Twitter) will fully open source its codebase once a security vulnerability review is completed. The announcement includes plans to invite third-party auditors to verify that the actual running system aligns with the open-source code. This move follows Musk's earlier commitment to open-source the algorithm for selecting posts, which was released on March 31, 2023. However, the algorithm's updates may not be reflected in the publicly available code. The current status indicates that the codebase is under review, with no specific vulnerabilities or attack vectors reported at this time. The open-sourcing aims to enhance transparency and trust in the platform's operations.

Key Points: • Elon Musk announced X's full codebase will be open-sourced after a security review. • Third-party auditors will verify the consistency between the running system and the open-source code. • The previous algorithm for selecting posts was released in March 2023 but may not reflect recent changes.
