What it takes to run
Configure a provider credential or local model unless using a separately billed OpenCode model service
Where your data lives
Project files remain local; configuration, sessions and snapshot metadata are local, and a session is uploaded only when the user explicitly shares it, while prompts go to the chosen provider
Why fork OpenCode instead of vibe-coding a Blackbox AI clone?
Do not mistake the interface for the product. Blackbox AI's durable value is model, context, integration, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
