Browser Runtime
Demo
Write a goal and get the exact command that runs it, then read what real runs produced. Execution happens on your machine: the runtime drives your browser with your keys, so nothing is sent to mlola.com and no public endpoint can be used to browse the web.
Example prompts
Choose one to load it into the playground. The proven prompts run where their requirements are met; the templates show the shape of a goal for your own application and never resolve as written.
Your prompt
npx @mlola/browser-cli browser run \
--goal "Download my latest invoice" \
--url "http://127.0.0.1:4311/billing" \
--headless --no-human --yes
Providers come from mlola.config.json, .env.local or the shell; check them with mlola browser config show before running. The first run opens its own Agent Window, and a tab of yours is borrowed only with your approval.
What a real run looks like

Want a hosted runner instead? That needs an allowlisted, rate-limited service on our side, and the runtime would no longer use your own logins, so running locally stays the default.
