Code Execution

Navigator includes code execution so the assistant can calculate, transform data, prototype logic, and produce artifacts without leaving the chat.

Execution backends

NEXT_PUBLIC_CODE_EXECUTION_BACKEND=local
E2B_API_KEY=

Use the local browser worker for lightweight execution. Add E2B when you want server-side sandbox execution and richer preview flows.

Data cleanup

Parse CSV, normalize fields, calculate totals, and produce clean tables.

Quick calculations

Run exact arithmetic, statistics, conversions, and small simulations.

API payload shaping

Transform JSON into the structure expected by an API, webhook, or workflow.

Chart preparation

Aggregate rows and prepare data for visualization tools.

Do not expose server-only secrets to browser-visible code execution. Keep private keys in server-side environment variables.
