OpenCode

A security-conscious engineering team cannot permit proprietary repository context to stream across third-party cloud servers. OpenCode places an autonomous agent directly inside the developer's shell and desktop, querying private endpoints or chosen model providers without storing source code remotely.

Why OpenCode instead of GitHub Copilot

GitHub Copilot routes coding assistance through proprietary infrastructure, transmitting editor buffers to hosted inference pipes and tracking activity with remote telemetry. OpenCode shifts the execution runtime entirely to your machine. Instead of a cloud subscription controlling token routing and model choice, OpenCode runs as a model-agnostic agent connecting to commercial APIs, internal enterprise gateways, or local engines like Ollama. Teams maintain complete custody over repository files, system commands, and internal APIs, ensuring sensitive IP never leaks to hosted caches.

Where Copilot emphasizes inline autocompletions in supported IDEs, OpenCode operates as an interactive agent that navigates project trees, consults Language Server Protocol diagnostics, runs shell commands, and executes multi-file refactors. This design eliminates the black-box limits of proprietary tools like Copilot and Cursor by letting engineers inspect prompts and govern tool execution explicitly. In exchange, teams take on operational responsibilities: you supply your own model keys, manage token limits, and handle latency instead of relying on a managed monthly seat fee.

What it does well

• Language server integration: Automatically loads language servers across the repository, giving the agent type signatures, definitions, and compiler errors before editing files.
• Dual execution personas: Provides a write-capable build agent alongside a read-only plan agent that prevents unintended edits and requires approval for shell commands.
• Multi-session concurrency: Lets engineers run parallel agent sessions on the same codebase to investigate bugs, write documentation, and run tests concurrently.
• Model neutrality: Connects to dozens of model providers, local runtimes, or private enterprise gateways, preventing vendor lock-in.
• Terminal and desktop interfaces: Runs in terminal emulators, as a desktop app on Linux, macOS, and Windows, or via editor extensions without forcing an IDE switch.
• Zero remote storage: Keeps chat sessions, repository context, and command logs local unless an engineer explicitly generates a share link.
