OpenCode lets you choose among supported model providers and local runtimes. Claude Code provides a Claude-centered coding workflow. Both need repository-specific tests and a review of the changes they make.
How to choose between these options
The choice begins with the model connection and development environment you want to maintain. OpenCode can be useful when changing providers or connecting a supported local model is a central requirement. Claude Code can fit a team whose Claude account or supported deployment route already matches its policies and working style.
Run the same bounded code task with the same acceptance criteria, then inspect the diff and test evidence. Changing both the agent and the model changes more than one variable, so do not attribute every difference to the client. A public code repository also does not make the products' licenses identical: check the actual client, model and service terms.
An open-source coding agent with terminal, desktop and web interfaces that can connect to hosted providers or local model runtimes.
Anthropic's coding agent reads repositories, edits files and runs development commands from terminal, IDE, desktop or web surfaces.
Model connection
Multiple hosted providers and documented local-runtime discovery.
Claude access through Anthropic accounts or supported cloud-provider deployments.
Offline-oriented setup
Can connect to an Ollama, LM Studio or vLLM endpoint; model capability still matters.
Official requirements include internet access; not a local-model runtime.
Agent-code license
MIT; provider and model licenses remain separate.
Proprietary commercial terms, despite a public repository.
Configuration burden
Choose a provider and explicitly review permissions; V1 and V2 differ.
Choose an eligible account/deployment route and configure organizational permissions.
Evaluation focus
Test the specific model/runtime/agent combination you plan to run.
Test the chosen Claude deployment and plan against your repository tasks.
A fair comparison starts with the same job. Models, agent products, automation platforms and inference engines are not interchangeable. The second selector narrows to compatible entries. Even then, use the same task, configuration and hardware for an actual test.
No independent tests were run. Official facts and editorial assessment are separate. The comparison link contains entry identifiers, not account or watchlist data.
