@isoldex/sentinel
AI-powered browser automation for TypeScript. Describe what you want in plain English, Sentinel figures out the selectors, clicks, and extracts data.

A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
Başlat
npm install @isoldex/sentinel playwright
npx playwright install chromium
Gemini works out of the box. The other providers load their SDK on demand — install the one you use:
npm install @anthropic-ai/sdk # ClaudeProvider
npm install openai # OpenAIProvider
# OllamaProvider needs no package, just a running Ollama instance
Using the Playwright test fixture (@isoldex/sentinel/test) additionally requires @playwright/test.
import { Sentinel } from '@isoldex/sentinel';
const sentinel = new Sentinel({ apiKey: process.env.GEMINI_API_KEY! });
await sentinel.init();
await sentinel.goto('https://github.com/trending');
const result = await sentinel.run(
'Extract the top 5 trending repositories with name, description, and star count'
);
console.log(result.data);
await sentinel.close();
A more complex multi-step task — search, filter by brand, sort by rating, extract structured data:
Running the same task with the same model (Gemini 3 Flash), Sentinel completed in 5 steps / under 20s / 23k tokens / $0.0019. Stagehand timed out at 300s+ with one decision call alone consuming 210k tokens.
Full benchmark methodology and raw data: isoldex.ai/benchmark
act() — natural language actions (click, fill, select, scroll)extract() — structured data extraction with Zod schemasrun() — autonomous multi-step agent with goal-driven planningfillForm() — declarative form filling with one JSON objectintercept() — capture API responses instead of scraping DOMnpx sentinel run "goal" --url https://...run() and fillForm() both accept maxSteps, timeoutMs, and an AbortSignal
via their options. Cancellation and time budgets are checked between steps and
after planning, before the next browser action starts.
Either a Gemini apiKey or a custom provider — the type system enforces one of them, and providers carry their own credentials:
new Sentinel({ apiKey: process.env.GEMINI_API_KEY! });
new Sentinel({
provider: new OpenAIProvider({ apiKey: process.env.OPENAI_API_KEY!, model: 'gpt-4o' }),
});
new Sentinel({ provider: new OllamaProvider({ model: 'llama3.2' }) }); // no key at all
Use variables for anything secret. The placeholder is resolved for the browser but never for a cache, so a file-backed cache stores %password% rather than the value:
await sentinel.act('Fill %password% into the password field', {
variables: { password: process.env.APP_PASSWORD! },
});
runStream() stops the agent as soon as you stop consuming it — a break, an exception, or an SSE client disconnecting. Pass signal to cancel from elsewhere (e.g. request.signal):
for await (const event of sentinel.runStream(goal, { signal })) {
if (isEnough(event)) break; // agent halts; no further tokens are spent
}
Defaults to 127.0.0.1:3333 with no authentication, which is safe only because it is loopback-only: requests are rejected unless Host and any Origin are loopback. Exposing it further requires a token, and the server refuses to start without one.
All requests share one browser session, so tool calls are serialised. HTTP mode decouples the client from the process; it is not a way to serve concurrent users.
