AI coding agents and a rerun of the operating-system wars
The article draws a parallel between the current landscape of AI coding agents and the historical operating system wars, highlighting how platform control and ecosystem compatibility influence user adoption. It argues that while underlying models are often proprietary, the surrounding software harnesses vary significantly in licensing and openness, creating distinct market positions for different tools. The author suggests that established conventions, such as those in Claude Code, may become industry standards that competitors must support to remain viable.
- ▪AI coding agents are compared to operating systems, with Claude Code likened to Windows, Codex CLI to BSD, and OpenCode to Linux based on their ecosystem dynamics.
- ▪Claude Code's proprietary nature is offset by a growing ecosystem of third-party plugins and MCP servers, creating a strong network effect similar to the Windows platform.
- ▪Competing tools like OpenCode are adopting Claude Code's file conventions, such as CLAUDE.md, to ensure compatibility with existing user workflows.
- ▪Codex CLI is released under the Apache 2.0 license and supports local models via providers like Ollama, distinguishing it from more closed systems.
- ▪The choice of software harness is increasingly separate from the choice of the underlying AI model, allowing users to mix and match components based on licensing and functionality.

Opening excerpt (first ~120 words) tap to expand
AI coding agents and a rerun of the operating-system wars Photo source: Rod Long (@rodlong) | Unsplash Attending the Agentic AI for Science workshop at MPCDF in Garching got me thinking about the platforms we are starting to build our scientific workflows around. The workshop programme brings together hands-on work with agents, examples from scientific software development and materials simulations, and perspectives from industry. For someone interested in free and open-source software, this raises some familiar questions: who controls those platforms, what can we change ourselves, and how much of our work can we take elsewhere? What interests me here is the software around the model. An agent harness gives the model tools, supplies context, and controls what it can do.
