Installation

Use a maintained Node.js 22 or 24 release. The npm package is captar; its command-line binary is captor.

npm install captar

The execution API needs no environment variables, provider keys, Captor account, or hosted database. JSONL is the default local store. SQLite uses Node's built-in node:sqlite; use a current Node 22+ release with that module available.

import { run, backfill, JsonlRunStore, SqliteRunStore } from 'captar';

Use the installed binary through an npm script, or explicitly select its package:

npx --package=captar captor runs
npx --package=captar captor inspect <run-id>

Existing AI integrations can continue using createCaptar. Their provider and optional telemetry configuration are documented in the AI compatibility quickstart.
