Browser Automation Unlocks Legacy Systems
David Mlcoch, co-founder & CEO of Asteroid, on browser automation and the last mile problem of AI
Browser automation turns old web software into a usable action layer for AI, which is what makes vertical agents actually complete work instead of stopping at analysis. In practice, the agent logs into the same insurer, clinic, or supply chain portal a worker uses, clicks through messy forms, handles popups, and writes back into the system of record even when no API exists. That is why browser automation matters most in industries still running core workflows through old portals.
-
The key technical shift is from brittle selector based scripts to agents that can interpret the page and recover from small changes. Older Selenium, Playwright, and UiPath style flows often break when a field moves or a popup appears. Newer AI driven systems can navigate those changes and then save reusable scripts for repeated tasks.
-
The product split is becoming clearer. Browserbase sells hosted browser infrastructure and developer tools for engineers building automations. Asteroid packages that capability for operations teams, with workflow capture, supervision, and no code building so an insurance broker or healthcare operator can automate a task without handing it to a developer or a UiPath consultant.
-
The wedge is strongest where the work is repetitive but not cleanly structured. Insurance quoting can require 150 question forms with branching logic, healthcare scheduling requires writing call outcomes into old practice software, and both depend on domain judgment as the agent moves through the portal. That is why browser automation is becoming the execution engine for voice agents and other vertical AI systems.
The market is moving from one off computer use to managed fleets of agents that run business processes all day inside hosted browsers. The winners will be the platforms that make those agents reliable, observable, and easy for domain teams to tune, which pushes browser automation from a developer tool into core enterprise workflow infrastructure.
