The article compares two AI coding tools, Anthropic's Claude Code and OpenAI's Codex CLI, highlighting the differing developer reactions due to licensing strategies. Codex CLI, licensed under Apache 2.0, encourages community engagement through open source contributions, while Claude Code is limited by a restrictive commercial license and copyright protections. After a developer's attempt to reverse-engineer Claude Code led to a DMCA takedown notice by Anthropic, negative sentiments surfaced among developers on social media. The article notes that Codex CLI's approach includes integrating developer feedback, contrasting sharply with Claude Code's guarded operations, which may influence future user loyalty.
In the battle between Claude Code and Codex CLI, developer goodwill favors OpenAI's Codex, attributed to Claude Code's restrictive licensing and takedown notices.
Codex CLI’s source code, available under Apache 2.0, allows for distribution and commercial use, whereas Claude Code's obfuscated code limits modifications without approval.
Developers reacted negatively to Anthropic's takedown notice against reverse-engineering Claude Code, highlighting the contrasting developer engagement strategies with OpenAI's more open approach.
Despite Claude Code being in beta and potentially evolving, current developer sentiment heavily leans towards Codex CLI for its openness and collaborative enhancements.
