OpenCode vs Claude Code: models, setup, pricing and limits

Quick answer: OpenCode vs Claude Code comes down to whether you want OpenCode’s provider choice or Claude Code with a Claude subscription or API billing.

The useful OpenCode vs Claude Code comparison starts with three questions: which model do you want, which account pays for it, and how will you check the result? A tool’s name alone does not answer those questions. This guide compares the documented setup and billing options, then gives you a small test for deciding which fits your work.

In my video, Why OpenCode Is Better Than Claude Code, I explore OpenCode after hitting a Claude usage limit. The site’s watch page calls it “OpenCode vs Claude Code: setup and model limits.” That recording shows a personal workflow comparison, including a failed request, rather than a controlled benchmark.

Licensing, models and providers are different choices

OpenCode’s old sst/opencode repository redirects to anomalyco/opencode, which lists an MIT license. Claude Code’s license file reserves rights and points to commercial terms. A public GitHub page is not, by itself, evidence that a product has an open source license.

For provider choice, OpenCode’s directory documents Anthropic, OpenAI, OpenRouter and local options such as Ollama. Its model documentation also describes local models. In V2, provider configuration covers the catalog and custom endpoints. Decide which service you trust and want to pay before choosing a model inside it.

Claude Code’s authentication docs cover Claude accounts, Console access and cloud providers including Amazon Bedrock, Google Cloud’s Agent Platform and Microsoft Foundry. Those are deployment and billing routes. The model configuration page explains the model aliases and identifiers available through them. Do not assume a cloud-provider option means an unrestricted catalog of unrelated models.

In the recording, I add an OpenRouter API key, try a Gemma request, encounter a rate-limit error, and switch back to Kimi. The practical lesson is to test one request before building a workflow around a model picker. Seeing a model name is not the same as completing the task.

Install the version you actually intend to use

OpenCode’s V1 introduction warns that V1 and V2 both use the command opencode and cannot sit side by side under that default name. Check an existing installation before replacing it. The V2 installation page lists this npm command:

npm install -g @opencode/cli

For Windows, the same V2 page says Windows package managers are unsupported and provides standalone CLI downloads. Use the download matching your platform rather than assuming an older installation tutorial applies. Once installed, run opencode inside your project, as shown in the CLI introduction.

Inside the terminal interface, use /connect and then /models. The provider sign-in guide documents API keys and other authentication methods; the choices depend on the integration. Complete that connection before asking for a code change.

For Claude Code on macOS, Linux or WSL, Anthropic’s setup guide recommends:

curl -fsSL https://claude.ai/install.sh | bash

That page has separate Windows instructions and system requirements. Run claude after installation and follow the login flow. Choose the intended account deliberately: installing a client does not establish which account will pay for requests.

Compare the billing route before comparing limits

Anthropic’s pricing page lists Pro at $20 when billed monthly and Max starting at $100 per month, before applicable tax. It lists Claude Code in Pro and Max. These are subscription prices, not promises about how many repository tasks you can finish. Check checkout and your account before purchasing.

With subscription access, Anthropic’s help center says Claude and Claude Code share usage. Pro and Max have five-hour session and weekly limits. The same page warns that an ANTHROPIC_API_KEY environment variable can cause API billing instead of consuming subscription usage. Check that setting when an unexpected charge or sign-in behavior appears.

For OpenCode, bring-your-own provider means checking the selected connection’s billing. OpenCode also offers an optional Console service: add credits, obtain an API key and pay for requests. Its documentation points to Go as a separate subscription with included usage. Therefore, “OpenCode is open source” and “this request costs nothing” are different claims.

Do not calculate a winner from the monthly subscription price alone. Record the model, the account charged, the completed task and the corrections you had to make. An unfinished answer is not equivalent to a checked change. This guide makes no fixed messages-per-day promise and gives no universal cost per task.

When to pick each, and how to make the decision

Try Claude Code first if you already use a Claude plan and want to evaluate its coding workflow through that account. Try OpenCode first if your main reason for testing is provider choice or inspecting an open source client. Those recommendations follow the Claude access routes and OpenCode repository; they are not a speed or quality ranking.

Use the same small brief for both: identify a broken link, explain the intended correction, change only the relevant file, and show how to verify it. Start each trial from the same files. Keep a note of setup time, failed requests, manual corrections and the final diff. Review the output before accepting it.

If a request fails, preserve the error and establish whether the problem is authentication, billing, model access or the code itself. Changing tools immediately can hide the cause. The failed request in my OpenCode walkthrough is a useful reminder to verify access before judging the coding result.

For a different comparison, continue to Claude Code vs Codex. For this decision, choose the setup that completes your actual work with an understandable bill and a result you can inspect.

FAQ

Is OpenCode free to use?

The OpenCode client is MIT-licensed open source. That does not make connected model usage free; check the provider or optional OpenCode service you choose.

Does Claude Pro include Claude Code?

Yes. Pro and Max include Claude Code when you sign in with your Claude account, and usage is shared with Claude.

Can OpenCode use Claude models?

OpenCode documents an Anthropic provider connection. Check the authentication method and billing for that connection before making a request.

Does OpenCode remove usage limits?

No. Changing the client is not a promise of unlimited model access. Check the selected service’s allowance and billing; Mike’s walkthrough includes a rate-limit failure.

Which should a beginner try first?

Start with one small, checkable task. Choose Claude Code if you want to use your existing Claude plan; try OpenCode if comparing providers is the purpose of your test.
