Ship browser automation to users with Ferr and Convex

Store state in Convex, run browsers with Ferr, and give your users automations that just work.

Engineering

If you are building a product on top of browser automation, you need two things: somewhere to keep state and something to run the browsers. Convex handles the first, Ferr the second.

The pattern

run.ts

import { Ferr } from 'ferr';
 
export async function runJob(url: string) {
  const s = await new Ferr().sessions.create();
  await s.goto(url);
  return await s.extract('summary');
}

Why it works

Convex keeps the job queue and results transactional; Ferr keeps the browsers warm and observable. Neither has to know much about the other.
