Choose opencode if you…
- want a terminal-based coding workflow with separate build and read-only plan agents.
- prefer a beta desktop app available for macOS, Windows, and Linux.
- need installation options such as npm, Homebrew, Scoop, or an install script.
Choose DeepSeek-Reasonix if you…
- want to configure model providers, tools, and plugins through reasonix.toml.
