How Vision LLMs Enable Self-Healing Web Automation Beyond Brittle DOM Selectors

Short summary

Traditional web automation relies on brittle DOM selectors that break when frontend code changes. Vision LLMs offer a paradigm shift by enabling agents to visually interpret the browser viewport, locate elements semantically, and execute actions resiliently—mimicking human perception. The article outlines a microservices-style architecture and an OODA-loop control cycle for building production-grade vision-driven browser automation systems.

• •DOM-based locators in Playwright/Puppeteer break frequently due to modern SPA complexity and randomized attributes
• •Vision LLMs enable self-healing automation by interpreting screenshots visually rather than querying DOM structure
• •Production architecture maps to three microservices (infrastructure, perception, orchestration) with an OODA-loop control cycle
