JetBrains Junie vs OpenCode

JetBrains Junie is a coding agent for work in JetBrains IDEs, a terminal, or headless CI/CD scripts. It offers chat assistance, codebase indexing, terminal access, and agent mode. Advanced Plan Mode lays out requirements, design, and delivery stages before code changes; plans can be edited and committed in.junie/plans. Users can review key actions, and the CLI requests approval for sensitive actions unless brave mode is enabled or an action is allowed. Junie supports models from OpenAI, Anthropic, Google, and xAI, while the CLI can use provider API keys directly. Remote Control lets users monitor asynchronous CLI runs in a web app. Project guidelines, Agent Skills packages, and slash commands shared across CLI and IDE through ACP are also supported. The IDE plugin works with listed JetBrains IDEs and Android Studio. The CLI runs on Linux, macOS, and Windows, though sandbox mode is limited to macOS and Linux. Free to Start is free with five AI credits; paid plans start at $8.33 a month per user.

OpenCode is an open source AI coding agent for working in a terminal, IDE, or desktop app. It provides chat assistance, agent mode, terminal access, and codebase indexing, and supports more than 75 LLM providers as well as local models. The software can load language servers for the selected model and coordinate multiple agents on one project. Editor extensions are listed for Visual Studio Code, Cursor, Zed, Windsurf, and VSCodium; GitHub and GitLab integrations are also available. Users can share session links, while conversations are private by default. OpenCode says it does not store code or context data. The free plan includes the open source agent and free models, or users can connect a model provider. OpenCode Go costs $10 a month and lists usage limits of $12 per 5 hours, $30 per week, and $60 per month. The site recommends WSL for Windows users for performance and full feature compatibility.
