Every automation leader has seen the same pattern. A bot runs fine for months. Then an update to the ERP changes a table header or a button label. The bot breaks. You open a ticket, wait for a developer, rewrite selectors, and redeploy. This rebuild-on-every-change cycle is the hidden cost of traditional low-code RPA. It eats up headcount and slows down new projects. Meanwhile, the same organization still has a growing pile of SOPs that people only run manually because building bots for them is too fragile and too expensive.
Why RPA breaks here
Low-code RPA tools like UiPath, Automation Anywhere, Blue Prism, and Power Automate rely heavily on selectors, xpaths, and object IDs. These are fragile anchors. When a software vendor updates its UI, those anchors drift. A single pixel shift in a button, a change in a class name, or a new layout can stop a bot in its tracks. Industry surveys show that approximately 40 to 60 percent of RPA maintenance effort goes into keeping bots running after UI changes. That means for every line of new automation code, a significant portion of your team’s time is spent patching existing bots. The rebuild-on-change cost compounds as your automation portfolio grows. You end up with a backlog of bots that are one update away from failure.
What changes with computer use agents
- Survives UI changes without rewriting bots
- No brittle selectors or xpaths to maintain
- Recovers from exceptions and unexpected states
- Follows the SOP as written, not a complex flowchart
- Works on legacy applications and Citrix environments where traditional RPA struggles
A computer use agent sees the screen the same way a human does and acts like a human, so it survives UI updates and recovers from unexpected states instead of halting.
How to move without the risk
You do not need to rip out all existing RPA overnight. Start with a high-pain, SOP-driven process that is currently running manually or is too brittle for traditional bots. Pick a process with clear steps that are already documented in plain English. Pilot a computer use agent on that process. Measure how often it succeeds compared with manual execution and with the existing RPA bot, if one exists. Once you see durable results, expand to similar processes. This phased approach lets you build confidence and evidence before scaling. It also keeps your existing RPA platform in place for high-volume, stable, backend tasks where it still makes sense. Computer use agents handle the long tail of changing UIs and exception-heavy work, while RPA handles the predictable, high-volume flows.
Practical next steps
The first step is to identify one process that is costing your team time and reliability because of UI fragility or manual work. Then, talk to the Coasty team about how a computer use agent can run that process while you keep your RPA investments.
The path forward is clear. Keep what works in traditional RPA and add computer use agents for the work that is currently too fragile or too manual. To see how a computer use agent can handle your most complex, changing workflows, book a demo with the Coasty team at https://cal.com/coasty/15min.
