OpenCode

OpenCode is an excellent choice for professional developers because it combines strong privacy guarantees with real, workflow-level integration. Unlike many assistants that are tied to a single vendor, OpenCode is model-agnostic: it works with GitHub Copilot, ChatGPT, and other LLMs, so teams can switch providers as pricing, capabilities, or compliance needs change without retooling their entire setup.

The LSP-based integration is a major advantage over tools that only see the currently open file. By plugging into the Language Server Protocol, OpenCode can understand your entire codebase—its structure, types, references, and dependencies—leading to more accurate completions, better refactors, and context-aware suggestions that feel like they come from someone who has actually read your project.
