@mlola/browser-runtime

Reliable browser use with a fast path: a local-first browser runtime where browser mechanics, safety, verification and recovery are deterministic, the fast decision path (TypeSafe Jev) handles routine steps, stronger models handle planning and recovery, and a person can take over whenever needed.

npm install @mlola/browser-runtime

import { BrowserAgent } from "@mlola/browser-runtime";

const agent = new BrowserAgent({ decision: { provider: "typesafe" } });

const run = await agent.run({
  goal: "Download my latest invoice, attach it to a new claim, then stop before submitting",
  startUrl: "https://billing.example.com/invoices",
  stopBefore: ["submit claim"],
});

console.log(run.status, run.verification?.status, run.artifacts);

• Models never produce selectors, coordinates or code — only choices from the runtime's own action space.
• DONE is a claim; completion is verified by independent evidence (artifacts, URL/state, DOM, runtime events) or a person.
• Secrets (passwords, OTP, cards) are a takeover floor and never enter model state or traces.
