The coding agent space now has a third major player with deep infrastructure behind it. For developers evaluating AI coding tools, Meta’s entry adds another option to benchmark against existing tools from OpenAI and Anthropic. Muse Code is currently in beta, so expect the feature set and pricing details to come into clearer focus as the release matures.
