Junie vs OpenCode (2026)

Junie

by JetBrains

OpenCode

by Anomaly Innovations, Inc

Pros

• ✓Runs in the terminal on Linux, macOS and Windows, inside JetBrains IDEs and Android Studio, and in CI through a GitHub Action and GitLab CI/CD.
• ✓Works with any model: JetBrains AI cloud models, bring-your-own-key from OpenAI, Anthropic, Google, xAI, OpenRouter or GitHub Copilot, and local models.
• ✓Plan mode writes an editable plan before coding, and in JetBrains IDEs Junie can drive the debugger and inspect runtime state.

Limitations

• –Cloud models beyond the free Junie Lite tier and the AI Free plan's 3 monthly credits need a JetBrains AI plan, a Junie API key or the developer's own provider keys.
• –Junie Local needs an Apple Silicon M4 or newer Mac with macOS 26 and 64 GB of RAM, or a Windows 11 PC with an NVIDIA RTX GPU and 24 GB of video memory.
• –Remote mode needs a JetBrains Account or Junie API key sign-in, and is not available through JetBrains AI Enterprise.

Pros

• ✓Developers can log in with GitHub Copilot or ChatGPT Plus or Pro to reuse existing subscription quotas, or connect any of 200+ providers including local models, with no separate API billing required.
• ✓Multi-session parallel agents run on the same project, and MCP client support covers local and remote servers with OAuth, so tools such as Sentry and Context7 connect inside the same workflow.
• ✓No code or context is stored, the agent is MIT licensed, and Anomaly Innovations publishes a SOC 2 Type 2 report through its Trust Center.

Limitations

• –Permissions start permissive: the Build agent edits files and runs shell commands without an approval prompt until a permission config is written, with only repeated identical calls, paths outside the project and reads of .env files gated.
• –Beyond the bundled free models, developers pay a provider directly or through Go or the OpenCode Console, and manage keys and accounts for each provider they use.
• –Enterprise pricing is quote-only, and the SOC 2 report and Data Processing Agreement are released through the Trust Center on request.
