OpenCode vs Claude Code (2026): Which Should You Pick?

Pick OpenCode if you want a free, open-source agent that runs any model — including local ones — and keeps your code private. Pick Claude Code if you want the fastest, most polished terminal agent and don't mind being on Anthropic's models and billing. Both are terminal-native, both are excellent, and the choice comes down to control versus convenience. Here's how they compare on the things that matter.

Quick verdict

OpenCode is the open-source leader — model-agnostic, private, and thorough thanks to deep LSP integration. Claude Code is the speed-and-polish leader, with Anthropic's latency engineering making it noticeably faster on the same model. If you value freedom and privacy, OpenCode. If you value raw speed and zero setup, Claude Code.

At a glance

Privacy	Local-first, SQLite	Hosted Anthropic models
Surfaces	Terminal, desktop (beta), IDE	Terminal, IDE
Cost	Free + model usage	Claude sub or API billing

OpenCode

OpenCode is the most popular open-source coding agent, past 160,000 GitHub stars and 7.5M monthly developers. Its two defining strengths are model flexibility — 75+ providers via Models.dev plus local models through Ollama — and its LSP integration, which feeds the agent real type information and compiler diagnostics. In DataCamp's testing that thoroughness showed up as 21 more tests generated on average than Claude Code on the same model.

It's also private by default: it runs locally and stores sessions in SQLite, so with local models nothing leaves your machine. The cost is speed — about 78% slower than Claude Code on the same model — and no inline autocomplete. Full detail in our OpenCode review.

Claude Code

Claude Code is Anthropic's terminal agent, and it's the one to beat on speed and polish. Anthropic has poured engineering into latency, so it's noticeably faster than OpenCode running the identical model, and it added computer use in 2026, letting it open apps and navigate a browser from the terminal. Setup is trivial: install, sign in, go.

The trade-off is lock-in. You run Claude models only, and you pay through a Claude subscription or API billing — there's no local-model escape hatch and no source to self-host. For most developers that's a fair price for the speed and reliability. See our Claude Code review and pricing guide for the specifics.

Cost compared

OpenCode's software is free — you pay only for model usage via your own API keys, or nothing at all with local models. Claude Code needs a Claude subscription or API billing on top of the tool. For a developer who already has API access or runs local models, OpenCode is clearly cheaper; for someone who just wants a working agent with one bill, Claude Code's bundled pricing is simpler.

Worth noting: you can run Claude models inside OpenCode, so "which is cheaper" often reduces to whether you value OpenCode's flexibility and local option enough to accept its slower speed.

Which should you pick?

Choose OpenCode if you want no vendor lock-in, the freedom to run any model (including private local ones), and the most thorough, test-heavy output — and you can live with slower runs. It's the pick for privacy-conscious teams and tinkerers.

Choose Claude Code if you want the fastest, most reliable terminal agent with zero setup and don't mind staying in Anthropic's ecosystem. For most professional developers who just want to ship, it's the smoother daily driver.
