how to use

How to Use Open Code

Open Code integrates into existing development workflows, providing AI assistance through a flexible interface. Users can get started by installing the tool and configuring their preferred AI models.

  • 1Install Open Code as a terminal interface, a desktop application, or an IDE extension, depending on your preferred development environment.
  • 2Configure your preferred Large Language Models (LLMs) by connecting to over 75 providers, including local models via Ollama, or by linking existing GitHub Copilot or ChatGPT Plus/Pro subscriptions.
  • 3Initiate an AI coding session within your terminal or IDE to begin writing, debugging, or refactoring code using natural language prompts.
  • 4Utilize "Plan mode" for architectural analysis, which allows for read-only examination and planning, requiring explicit approval before any modifications are made to the codebase.
  • 5Automate repetitive coding tasks by integrating Open Code's non-interactive CLI scripting capabilities into your continuous integration (CI) pipelines.
  • 6Share active coding sessions via generated links for collaborative debugging or to provide references to specific development contexts.

pricing

Open Code Pricing & Plans

Open Code operates on a freemium model, providing a robust free tier alongside a paid subscription option for enhanced capabilities. Costs are primarily associated with the usage of the chosen underlying AI models.

  • Free Tier: Free. This tier includes access to free models and the ability to connect any model from any provider, allowing users to leverage their existing AI subscriptions or local models.
  • OpenCode Go: A low-cost monthly subscription plan launched in early 2026. Specific pricing details for OpenCode Go are not publicly detailed, but it is positioned as an affordable option for advanced features.

Pros

  • +Open-source core provides transparency and community-driven development, boasting over 160,000 GitHub stars by June 2026.
  • +Model-agnosticism supports over 75 LLM providers, including local models via Ollama, preventing vendor lock-in.
  • +Flexible deployment across terminal, desktop application, and IDE extensions caters to diverse developer workflows.
  • +Privacy-first design ensures no storage of user code or context data, crucial for sensitive projects.
  • +Integration with existing GitHub Copilot and ChatGPT Plus/Pro subscriptions leverages existing investments.
  • +"Plan mode" offers controlled architectural analysis, requiring explicit approval before code modifications.

Cons

  • Setup for local models can be complex for some users, requiring technical proficiency.
  • Still maturing compared to some highly polished commercial alternatives, as noted in user reviews.
  • Managing context windows and navigating very large codebases may require further polish for optimal efficiency.
  • Specific pricing for the "OpenCode Go" subscription is not publicly detailed, limiting cost transparency.
  • EU AI Act obligations for provider/deployer are currently unknown, posing potential compliance questions.

Cline

Cline is an open-source AI coding agent designed for editor-first workflows with 'Plan/Act' oversight and permissioned file, terminal, and browser access.

Similar to Open Code, Cline is an open-source AI coding agent that works in the terminal and IDE. Its 'Plan/Act' oversight and broader access (browser, MCP) suggest a more autonomous and integrated workflow compared to Open Code's general assistance.

3

Qwen Code is an open-source AI coding agent that actively iterates on itself, using its own agents and models to file issues, submit PRs, and review code.

Qwen Code is also an open-source, terminal-native AI coding agent like Open Code. Its unique self-iterating capability for development tasks suggests a higher level of autonomy and meta-development compared to Open Code.

4

The Pair is a free, open-source desktop app that uses two AI agents (a Mentor and an Executor) to cross-check each other's code, aiming to catch AI hallucinations.

While Open Code is a single AI coding agent, The Pair offers a unique multi-agent approach for enhanced code quality and hallucination detection, operating as a desktop app with a CLI version, similar to Open Code's environment flexibility.

5

Gemini CLI is a free, open-source AI agent that brings Google's Gemini capabilities directly into the terminal, offering powerful AI assistance at the command line.

Gemini CLI is a direct open-source, terminal-based competitor to Open Code, leveraging the advanced AI capabilities of Google's Gemini models. Its primary differentiator is the direct integration with Gemini's AI, potentially offering different strengths in code generation and understanding.
