OpenCode vs Claude Code: Which Should You Pick?

At a glance

OpenCode is an open-source coding agent that runs on your machine and lets you choose among many model providers, including local models. Claude Code is Anthropic’s terminal-first agent, built around Claude models, with additional editor, web, and mobile surfaces. The key choice is whether provider flexibility and self-hosting matter more than a Claude-centered toolset with broader first-party interfaces.

Model choice and openness

OpenCode supports more than 75 providers through Models.dev, as well as local Ollama models. You can choose a provider and model per agent or session, and bring your own provider API keys, which are stored locally. Its software is free to install and run, and the project publishes its repository, releases, and a container image. This makes it a fit for developers who want to change models without changing coding tools, or use an internal AI gateway.

Claude Code uses Claude models only. You can select a Claude model and effort level for a session or subagent, and use an Anthropic API key or supported cloud accounts, but you cannot route it to GPT or other non-Anthropic models from inside the product. Anthropic’s public repository contains plugins, documentation, and an issue tracker, not the CLI source; its repository carries an all-rights-reserved licence. Choose OpenCode if model choice or open-source software is a requirement. Choose Claude Code if a Claude-only stack suits your work.

Pricing and usage

OpenCode’s core software is free. Optional OpenCode Go is $5 for the first month, then $10/month; OpenCode Zen is pay-as-you-go per token, and several Zen models are offered free of charge for a limited time. Go has usage caps of $12 per 5-hour window, $30/week, and $60/month. The requests those limits buy vary by model. Zen workspaces can share a balance with a workspace-wide monthly ceiling and separate member limits.

Claude Code’s Pro plan is $17/month billed annually or $20/month billed monthly. Max starts at $100/month. The free Claude tier does not include Claude Code, so access starts with a paid plan or API pay-as-you-go. Subscription plans meter a per-seat allowance; Console and cloud-provider use is billed per token. On Team, each member has an individual allowance on rolling five-hour and weekly windows rather than a pooled allowance. Heavy use can push costs up, and Max is the higher-priced plan for more headroom.

For buyers who want the coding agent software itself to cost nothing, OpenCode has the clearer entry point, though model use may still incur charges. For buyers who prefer a Claude subscription or API billing, Claude Code lays out those routes. Neither product’s listed prices alone predict the cost of a particular workload.

Workflow and surfaces

Both products have a terminal interface and can be used in engineering workflows. Claude Code’s terminal CLI is its primary surface; first-party extensions are available for VS Code, Cursor, and JetBrains, and cloud sessions are available through a browser and iOS and Android apps. It also integrates with GitHub Actions and GitLab CI/CD. The agent can read a codebase, run commands with permission, write tests, and work on multi-step tasks. Dynamic workflows use subagents for audits and large migrations.

OpenCode’s terminal interface is also primary. It has a VS Code-family extension and a browser interface, but the browser version is a local server that you start yourself, not a hosted service you log into. Its built-in build and plan agents distinguish full-access development from read-only analysis, and it can run several sessions in parallel. It also loads language-server integrations for project languages and supports MCP clients and custom skills. OpenCode documents whole-repository search with an Explore subagent, but does not claim repository-wide migrations.

For teams seeking more first-party interfaces and managed cloud sessions, Claude Code covers more surfaces. For developers who prefer a tool they run themselves and can connect to their chosen model provider, OpenCode is the closer fit.

Control, deployment, and security considerations

Both tools provide permission controls. Claude Code starts read-only and can ask for approval per action; rules and permission modes define what it may do. Its Auto mode can use a classifier to approve tool calls, and routines and background sessions can run unattended. OpenCode gates tools with allow, ask, and deny rules, including rules for file paths and shell commands; its default asks for approval on external directories and repeat loops, while its –auto flag approves everything not explicitly denied.

Neither product documents deployment as a built-in final step. Claude Code’s described workflow ends at a commit, branch, and pull request; deployment depends on shell commands it is permitted to run. OpenCode’s documented GitHub Actions workflow can work on a branch and submit a pull request, with no deployment step documented.

OpenCode’s local HTTP server and web UI have a disclosed history of two patched security advisories from 2026. Its listing also notes an open issue with reports of terminal UI memory growth; several fixes have landed, while heap-snapshot work continues. Take particular care before running its server on a shared or untrusted network. Claude Code publishes SOC 2 Type 2 and ISO 27001 artefacts at its Trust Center; HIPAA-ready and zero-data-retention options are available for Enterprise. These are different kinds of information, not a like-for-like security comparison.

Which one to pick

Pick OpenCode if you want open-source software, freedom to switch among model providers, local-model support, or the option to run the agent on your own machine or server. It also suits developers who want to avoid a required paid subscription for the agent itself and are comfortable configuring their providers and managing the software. Review its disclosed local-server security history before exposing that server to a shared or untrusted network.

Pick Claude Code if you want an agent centered on Claude models, prefer its terminal and first-party editor or cloud options, or need its documented CI integrations and enterprise controls. Its paid-plan and API routes may suit a team that accepts a single-vendor model stack. If switching to GPT or another provider inside the coding agent is essential, Claude Code does not offer that option.
