A free OpenAI Codex alternative for VS Code
VibeFree is a free alternative to OpenAI Codex: a VS Code extension that reads, edits, and debugs code across your project, with no subscription ever. Codex has no standalone price - it's bundled into ChatGPT Plus at $20/month or higher tiers, or billed by the token through the API.
- Reads, creates, and edits files across your project, with inline diffs in the chat panel.
- Greps and globs your entire codebase to find the right code before editing.
- Runs shell commands and manages long-running background tasks.
- Connects to any Model Context Protocol (MCP) server and calls its tools directly.
- No credit card or subscription required.
How Codex is priced: Codex is not sold on its own - you get it by subscribing to ChatGPT Plus ($20/month) or a higher tier, or by paying per token through the OpenAI API. The $20/month figure in the table below is the cost of the cheapest ChatGPT plan that includes it, not a Codex-only price.
