Greptile expands defect detection beyond code review using GPT-6 Astra

Greptile leverages the computer use capabilities of GPT-6 Astra to launch development servers for pull requests, resize browser viewsports to iPhone dimensions, and simulate user interactions. It relies on visual understanding to identify issues invisible to traditional code review. It also strengthens customer security with Daybreak and uses Codex via MCP server to read its knowledge base, reducing code rollbacks. Thousands of customers have already adopted the platform.
