  description

  Standby keeps browser tasks running in the background — persistently, autonomously, and locally.
  
  HOW IT WORKS
  
  1. Install the local companion app:
     npm install -g standby-agent
  
  2. Install this Chrome extension
  
  3. Open the side panel and type a goal:
     "monitor my inbox"
     "track this product's price"
  
  4. Standby observes the page, plans the next action, and executes it directly in your browser
  
  
  Each task runs in its own Chrome tab group. The local daemon checks tasks on a schedule and runs them when needed. If something goes wrong, Standby pauses and waits for you.
  
  
  WHAT YOU NEED
  
  - This Chrome extension  
    Handles page observation and action execution
  
  - The local companion app "standby-agent"  
    Handles task orchestration, scheduling, and model calls
  
  - An API key (bring your own)  
    Supports Claude, ChatGPT, Gemini, or any OpenAI-compatible endpoint
  
  
  Both the extension and the companion app are required.  
  The extension connects only to your local machine at 127.0.0.1

  Standby keeps browser tasks running in the background — persistently and autonomously.
  
  GET STARTED IN SECONDS

  HOW IT WORKS
  
  1. Open the side panel and type a goal, like "monitor my inbox" or "track this product's price"
  2. Standby observes the page, plans the next action, and executes it directly in your browser
  3. Each task runs in its own Chrome tab group, checking on a schedule and running when needed
  
  If something goes wrong, Standby pauses and waits for you.
  
  WANT FULL CONTROL? RUN LOCALLY
  
  For complete privacy, run everything on your machine:
  
  1. Install the local companion app: npm install -g standby-agent
  2. Open the side panel and choose Local mode
  3. Bring your own API key for Claude, OpenAI, or Gemini
  
  In local mode, the extension connects only to your machine at 127.0.0.1. Your data stays in a local SQLite file.
