OpenCode vs Claude Code
OpenCode (opens in a new tab) and Claude Code (opens in a new tab) are two of the most popular AI coding agents you can run in a terminal. They solve the same problem — an AI agent that reads your codebase, plans changes, edits files, and runs commands — but they take very different approaches to openness, model choice, and billing.
Here is a practical comparison to help you pick the right one for your workflow.
Quick verdict
- Choose OpenCode if you want an open-source agent, the freedom to switch between 75+ LLM providers (including local models), or you already have API keys from multiple vendors.
- Choose Claude Code if you are all-in on Anthropic's Claude models and want the official, first-party experience that always ships new Claude capabilities first.
Many developers keep both installed: OpenCode for provider flexibility and experimentation, Claude Code for Claude-specific workflows.
Side-by-side comparison
| OpenCode | Claude Code | |
|---|---|---|
| Made by | Open-source community (Anomaly) | Anthropic (official) |
| Source code | Fully open source on GitHub (opens in a new tab) | Closed-source client |
| Model support | 75+ providers: Anthropic, OpenAI, Google, DeepSeek, local models via Ollama, and more | Claude models (Anthropic API, Amazon Bedrock, Google Vertex AI) |
| The tool itself | Free | Free |
| You pay for | Your own API keys (BYOK) or OpenCode Zen usage | Claude subscription or Anthropic API usage |
| Interfaces | Terminal TUI, CLI, Web, IDE extension, GitHub & GitLab | CLI, desktop app, web, IDE extensions, GitHub Actions |
| Extensibility | MCP servers, agents, skills, plugins, custom tools | MCP servers, subagents, skills, hooks, plugins |
| Local / offline models | ✅ Yes, via local providers like Ollama | ❌ No |
| Fine-grained permissions | ✅ Permissions system | ✅ Permission modes |
| Best for | Provider flexibility, open-source stacks, cost control | Teams standardized on Claude, first-party support |
Where OpenCode wins
Model freedom. OpenCode's biggest advantage is that it is not tied to one vendor. You can point it at Anthropic for hard reasoning tasks, a cheaper provider for routine edits, or a fully local model via Ollama when working with sensitive code — all from the same tool. See the providers guide for the full directory.
Open source. The entire agent is open source. You can read exactly what it does, patch it, self-host the server, and build on the SDK without vendor approval.
Cost control. There is no required subscription. Bring your own API keys and pay providers directly, or use OpenCode Zen — a curated model gateway that includes free models to start with.
Where Claude Code wins
First-party Claude integration. Claude Code is built by Anthropic, so new Claude models and agent capabilities land there first, with tuning that third-party tools have to catch up to.
Polish and support. As an official commercial product it comes with vendor support, enterprise deployment paths (Bedrock, Vertex AI), and tight integration with the Claude subscription plans.
Ecosystem momentum. Claude Code has a large ecosystem of community plugins, skills, and workflows built specifically around Claude's behavior.
FAQ
Is OpenCode really free?
Yes. OpenCode is open source and the tool costs nothing. You only pay for the LLM usage itself — either through your own provider API keys or through OpenCode Zen's pay-per-use models (some Zen models are free). See getting started to install it in about 30 seconds.
Can OpenCode use Claude models?
Yes. Add your Anthropic API key and OpenCode can run Claude models like any other provider, while keeping the option to switch providers per task. Setup takes one /connect command — see the providers guide.
Can I migrate from Claude Code to OpenCode?
The concepts map closely: both support MCP servers, agent instructions (AGENTS.md / CLAUDE.md), skills, and permission controls. Most workflows transfer with minimal changes — start with the configuration guide.
Which one is better for beginners?
Both install in under a minute. If you already have a Claude subscription, Claude Code is the shortest path. If you want to try different models before committing to a vendor, start with OpenCode + Zen, which includes free models.
