OpenCode vs Claude Code
Choose OpenCode when using different model providers in one client is a requirement. Choose Claude Code when your team already uses Anthropic’s coding workflow and the account and interface you need are supported. Both have terminal and editor workflows; the decisive difference is usually model/account flexibility and how much existing configuration you would need to move.
Keep Claude Code if it already meets your needs and you have no specific provider or workflow limitation to solve. If you want OpenCode’s provider choice, start with installation and migrate one model connection before moving rules or tools.
Documented differences
| Question | OpenCode | Claude Code |
|---|---|---|
| Where do I start? | Installation and introduction | Anthropic's overview (opens in a new tab) |
| How do I connect a model? | Provider configuration and credentials; model choice depends on the provider | Account and provider options depend on the chosen surface |
| Which interfaces are documented? | Terminal, CLI, web and editor integrations | Terminal, IDE extensions, desktop and browser |
| How is usage paid for? | Hosted inference is subject to the connected provider's billing | Subscription or API/provider arrangements depend on account and surface |
| Can I customize the workflow? | Rules, agents, permissions and MCP configuration | Project instructions, skills, hooks and MCP configuration |
Check current supported providers rather than assuming any account works in every interface. The OpenCode provider reference and Claude Code overview (opens in a new tab) are the starting points for those differences.
What a migration actually involves
| Existing need | OpenCode setup to review |
|---|---|
| A default model and provider key | Providers and model selection |
| Repository instructions | Rules and AGENTS.md |
| Separate planning or specialist behavior | Agent configuration |
| Shell and file-access approvals | Permissions |
| External tools and data | MCP servers |
| Repeatable prompts | Custom commands |
| Editor interaction | IDE integration |
Move one category at a time. Start with one working provider, then copy the intent of a project instruction into the destination format. Check each tool separately; similarly named configuration fields need not have identical meaning.
Model choice and hosted services
OpenCode can use Zen or other supported providers. That is useful when your workflow requires comparing providers within one client. It also means you need to understand which account pays for a particular request.
For an existing Claude workflow, keep the provider and model fixed during the initial client comparison. If you later switch providers, record that as a separate trial. The Fable setup guide provides an example of checking native IDs and gateway aliases.
Terminal, editor and automation
Try the OpenCode TUI for an interactive task and its CLI for a repeatable command. Claude Code also documents multiple interfaces, so choosing between the tools should include the interface you will actually use. A terminal-only comparison cannot establish which editor experience you prefer.
Before adding repository automation, review the GitHub integration and its permissions. For everyday use, start with the reviewable coding workflow, then compare alternatives in the broader agent guide.
Which should you choose?
| Your situation | Recommendation | Tradeoff |
|---|---|---|
| You need models from several providers or your own compatible endpoint | Choose OpenCode and configure one provider first | You manage endpoint compatibility and provider billing |
| Your team already uses Claude Code instructions and approved accounts | Keep Claude Code unless a specific requirement is unmet | Moving clients means rechecking rules, tools and permissions |
| You want to try a different client with the same Claude model | Try OpenCode alongside your current setup | API access and existing subscription allowances may differ |
These recommendations concern workflow fit. They do not establish a code-quality or speed winner.
Give both tools the same small task from a known repository state. Review the accepted diff, test results, actual cost and time spent correcting the output. A comparison with different models measures the combined model and client, so record both.
Migrating configuration
Similar feature names do not make configuration files interchangeable. Inventory your instructions, MCP endpoints, credentials and permission rules before moving them. Keep keys out of version control. Test one provider and one bounded task first, then add integrations one at a time.
Review permissions in the destination tool rather than copying an approval policy and assuming it has the same precedence. A successful model connection does not verify shell access, file boundaries or MCP behavior.
The connection checklist helps isolate API errors. The Claude model guide lists native model IDs and explains the distinction between Anthropic and gateway access.
Complete your first OpenCode setup
Follow installation → provider configuration → model selection. Keep your first request small. If it fails, the connection checklist separates credentials, model IDs, network problems and quotas.
After the first successful task, migrate project configuration and the rules or tools your project actually uses. You do not need an SDK or server integration to compare everyday coding workflows.
Compare total cost
Separate the client, subscription allowances, token charges and additional services. Use invoices or usage records for the same workload. Neither a free client nor an existing chat subscription establishes free API inference.
