The Connectivity Challenge
In an ideal world, every system would expose a well-documented API. In practice, many critical business applications — particularly legacy systems, government portals, and older SaaS platforms — offer no programmatic access at all. The only interface is a web browser.
Browser automation bridges this gap by interacting with web applications the same way a human would: navigating pages, filling forms, clicking buttons, and extracting data from the screen.
When to Use Browser Automation
Browser automation is the right choice when three conditions are met: the target system lacks a usable API, the process is repetitive and well-defined, and the data volumes are manageable (browser automation is inherently slower than API calls).
Common use cases include data entry into legacy portals, extracting reports from systems that only offer CSV downloads through a web interface, and synchronising data between systems that have no native integration.
When to Avoid It
Browser automation is fragile by nature. Any change to the target application's interface — a moved button, a renamed field, a redesigned page — can break the automation. If the target system updates frequently, the maintenance burden may outweigh the efficiency gains.
For high-volume, time-critical processes, API integration is almost always preferable. If an API exists but is poorly documented, investing time in understanding it will typically yield a more robust solution than browser automation.
Hybrid Approaches
Many real-world implementations combine both approaches. API integration handles the high-volume, well-supported connections, while browser automation fills the gaps for legacy systems that resist modernisation. The orchestration layer coordinates both, presenting a unified workflow regardless of the underlying connectivity method.
