CloneDex: Rebuilding OpenAI Codex with VibeKit
We rebuilt OpenAI Codex as an open-source reference implementation using VibeKit, E2B sandboxes, Inngest job queues, and GitHub OAuth. CloneDex turns plain-language tasks into working pull requests through secure container orchestration and real agent execution.

CloneDex is our open-source attempt to understand and rebuild OpenAI Codex using modern developer tools. It's a real coding agent that takes plain-language tasks, runs them in secure E2B containers via VibeKit, and produces working GitHub pull requests. No demo shell or fake eval—just structured coding workflows that install packages, write code, run tests, and push changes.
