Side-by-Side Comparison
All three agents at a glance. Prices reflect individual plans as of mid-2025.
| OpenCode | Claude Code | GitHub Copilot | ||
|---|---|---|---|---|
| Price | Free (BYOK) No subscription | $20/mo + API usage | $10/mo Individual | |
| Models | Any LLM (OpenAI, Anthropic, Google, local, open-source) | Claude 4 / 3.5 Sonnet only | GPT-4o, Claude (limited) | |
| Open Source | Yes — MIT license | No | No | |
| Privacy | Fully private — runs with your own API key, no proxy | Privacy mode available (extra $) | API data not used for training | Enterprise data protected |
| Platform | Terminal + editor agnostic | VS Code fork | Terminal (any editor) | VS Code, JetBrains, GitHub.com |
| Stars / Reach | 160K+ GitHub | N/A (closed) | 77M+ users |
OpenCode — Open Source, Any LLM, Privacy First
OpenCode is the fastest-growing AI coding agent for one reason: it doesn't lock you in. Bring your own API key — OpenAI, Anthropic, Google, Groq, or any open-weight model running locally — and get the same agent experience without a subscription or data leaving your machine.
- Use any LLM backend — switch providers on the fly
- Fully private — your code never touches a third-party proxy
- Terminal-native, works with any editor or IDE
- Open source (MIT) — auditable, extensible, self-hostable
- 160K+ stars on GitHub and the community keeps growing
If you value privacy, flexibility, and want to use the models you already pay for, OpenCode is the no-brainer choice.

Claude Code — Best for Complex Reasoning
Claude Code is Anthropic's official coding agent. It excels at multi-step reasoning, large refactors, and understanding nuanced requirements. If your work involves complex logic, architecture decisions, or migrating large codebases, Claude Code's reasoning depth is a genuine differentiator.
- Deep reasoning — understands complex, multi-file changes
- Agentic — can run tests, search code, and iterate autonomously
- Terminal-native — works with any editor
- Powered by Claude 4 / Claude 3.5 Sonnet
# Install via npm npm install -g @anthropic-ai/claude-code
GitHub Copilot — Best GitHub Integration
GitHub Copilot is the most widely adopted AI coding assistant, with over 77 million users. It offers inline completions, chat, and agent mode — all deeply integrated with GitHub. If you live in pull requests and issues, Copilot's ability to understand your entire repo context is hard to beat.
- Deep GitHub integration — understands issues, PRs, repo context
- Multi-platform: VS Code, JetBrains, GitHub.com, CLI
- Agent mode for autonomous task execution
- Free for verified students and open-source maintainers
# Install the extension in VS Code # Or use gh CLI: gh extension install github/gh-copilot
Quick Pick — Which one to start with?
A decision tree for the indecisive.
Start here
→ OpenCode # free, any LLM, open source
elif you want the smoothest editor experience:
→ elif you need deep reasoning for complex refactors:
→ Claude Code # best at multi-step logic
elif you're already deep in the GitHub ecosystem:
→ GitHub Copilot # PRs, issues, actions integration
else:
→ start with OpenCode # lowest risk, highest flexibility
Try multiple
All three tools can coexist. There's no rule that says you must pick one. Use OpenCode for privacy-sensitive work and local models, Claude Code for heavy refactors, and Copilot for GitHub-native workflows. The best setup is the one that stays out of your way.
