About OpenCode

OpenCode is an open-source, terminal-based AI coding agent built in Go that provides a rich TUI for interacting with AI models to perform code generation, debugging, refactoring, and development automation, created by the team at SST and released in late 2025. It solves the problem of vendor lock-in in AI coding tools by supporting over 75 model providers including OpenAI, Anthropic, Google Gemini, AWS Bedrock, Groq, Azure OpenAI, and OpenRouter, all through a single free tool with no subscription fees. OpenCode has rapidly gained over 95,000 GitHub stars, becoming one of the most popular open-source AI coding agents.

OpenCode offers an interactive TUI built with Bubble Tea, vim-like editing capabilities, persistent SQLite storage for session management, and Language Server Protocol integration supporting 40+ built-in LSP servers for TypeScript, Python, Go, Rust, Java, and more. The tool allows AI to execute commands, modify files, and reason about code structure with full project context, while developers maintain control through review and approval workflows. Unlike subscription-based competitors, OpenCode lets developers bring their own API keys or run local models through Ollama at zero API cost.

OpenCode targets developers who want a powerful, free, and open-source alternative to proprietary AI coding agents like Claude Code, with the flexibility to choose any AI model provider based on performance, cost, or privacy requirements. It is particularly popular among developers who prefer terminal-based workflows, those running local models for offline or air-gapped development, and cost-conscious teams who want enterprise-grade AI coding assistance without monthly subscriptions. OpenCode's MIT license and active community make it a practical foundation for customization and extension.

Pricing & Platform Specs

Pricing Summary

OpenCode is 100% free and open-source under the MIT license with $0 software licensing fees.

Top Pick

Anthropic's agentic coding CLI

Anthropic's agentic CLI coding tool that delegates complex tasks to Claude directly from the terminal. Understands entire codebases via automatic context gathering, edits multiple files, runs shell commands, and manages Git workflows autonomously. Supports CLAUDE.md for persistent project instructions, integrates with VS Code and JetBrains, and uses Claude Opus/Sonnet with extended thinking for complex architectural decisions. Built for terminal-first developers.

Pi

Minimal terminal coding harness

Pi Coding Agent is an MIT-licensed Node.js CLI from earendil-works for building and running coding agents in a local terminal. The current package describes a read/bash/edit/write toolset and session management, while the repo positions Pi as a unified LLM API, agent loop, TUI, and coding-agent CLI. It is best framed as a lean, self-extensible BYO-model toolkit rather than a managed IDE.

Cline

OpenCode vs Cline — Terminal Coding Agent or VS Code HITL Agent?

OpenCode and Cline both deliver open-source agentic coding help, but they live in different shells. OpenCode is an MIT coding agent spanning terminal, IDE extension, and desktop, with any-provider models and a polished coding-agent loop. Cline is an Apache-2.0 coding agent for editor, terminal, and SDK workflows that reads and edits files, runs commands, and asks for explicit approval unless you enable auto-approve. Existing Scores: OpenCode overall 83 (Score date 2026-09-05); Cline overall 84 (Score date 2026-03-25). Overall is close; choose on terminal coding-agent DX vs editor human-in-the-loop control. Treat the scoreboard as review evidence with those dates, not the whole decision.

Goose vs OpenCode: Local MCP Agent or Open-Source Coding Agent?

Goose and OpenCode both run open-source AI agents that help developers ship work from the terminal, but they emphasize different product shapes. Goose is an open-source, model-agnostic local agent from the Agentic AI Foundation (AAIF) lineage — Desktop, CLI, and API — built around MCP extensions, recipes, and BYOK or local Ollama. OpenCode is an open-source coding agent spanning a terminal interface, IDE extension, and desktop app, with any-provider models and a polished coding-agent loop. Use Goose when you want a privacy-forward local agent with deep MCP extensibility across code and broader workflows. Use OpenCode when you want a coding-agent surface across terminal, IDE, and desktop with strong day-to-day developer experience. Existing aicoolies Scores: Goose overall 84, speed 80, privacy 95, developer experience 78 (Score date 2026-03-29); OpenCode overall 83, speed 81, privacy 90, developer experience 86 (Score date 2026-09-05). Overall is close; choose on product shape first, and treat the scoreboard as secondary review evidence with those dates.
