AWS has released the Amazon Bedrock AgentCore Browser Tool, a managed capability that lets AI agents interact with legacy web applications through the browser interface itself rather than through an API. The tool is part of AWS's broader AgentCore platform for building and deploying AI agents, and it's aimed squarely at a problem many companies have quietly worked around for years: business-critical software that has no integration path.
Legacy web applications, internal tools built a decade ago, vendor portals with no public API, older SaaS products that were never designed for programmatic access, are common in the operational stack of small and mid-sized B2B companies. When a business needs to move data in or out of these systems, the standard answer has been manual entry: someone logs in, clicks through the interface, and copies information by hand. According to AWS, the Browser Tool is designed to let an agent do that work instead, navigating pages, filling forms, and extracting information the same way a person would, but running as an automated, sandboxed process managed by AWS rather than a locally hosted browser automation script.
This differs from typical robotic process automation (RPA) tooling in one respect worth noting: the browser session is managed and isolated by AWS's infrastructure rather than run on a local machine or self-hosted server, which AWS positions as reducing the operational overhead of maintaining browser automation at scale. AWS's post walks through a reference architecture for building agents that authenticate into a legacy system, perform a defined task, and hand results back to a broader workflow, positioning the tool as one building block within Bedrock's AgentCore agent framework rather than a standalone RPA product.
For a company evaluating this, a few things are worth being precise about. This is not a way to add API-like functionality to a legacy app; it's a way to automate the manual browser interaction that a human would otherwise perform, which means it inherits the same fragility that any UI-based automation has: if the legacy application's interface changes, the automation can break. AWS's documentation frames the tool as suited to bounded, well-defined tasks, such as pulling a report, submitting a form, checking a status, rather than open-ended navigation of unfamiliar systems. Pricing and regional availability details are in AWS's documentation and were not fully detailed in the announcement; teams considering it should confirm current terms directly with AWS before committing.
The broader signal is that browser-level automation is now being folded into major cloud providers' agent platforms as first-party tooling, rather than left entirely to third-party RPA vendors or custom scripts. For companies with legacy systems in their stack, this lowers the technical barrier to trying agent-based automation on tools that were previously considered unautomatable without heavy custom engineering.
