Vendor Lock In: Escaping Proprietary RPA Platforms with AI Agents
Your finance team spent three months building an accounts payable bot to parse invoices, validate totals, and post to the ERP. Last week the ERP vendor released version 12.3. The selectors no longer map. The bot stops. A developer has to open the project, hunt down every broken selector, and glue new ones in. That is the maintenance treadmill. In large enterprises this cycle repeats dozens of times a year, creating a growing backlog of broken bots and a shrinking ROI on the original automation spend.
Why RPA breaks here
Most enterprise RPA (UiPath, Automation Anywhere, Blue Prism, Power Automate) automates by binding to specific UI elements. It uses selectors, class names, xpaths, or object IDs to locate a button or field. When a vendor updates a UI, renames a control, or changes the DOM structure, those bindings break. The bot halts. The average enterprise reports that 30 to 45 percent of RPA bots require at least monthly maintenance, with some teams seeing rebuilds triggered by every major software update. Each rebuild needs a developer, a QA cycle, and a deployment. The cost compounds. The risk of a missed change grows. The platform you chose becomes a dependency, not an enabler.
What changes with computer use agents
- ●Survives UI changes: Agents see the screen and can find the right element even if the underlying selectors shift.
- ●No brittle selectors: Agents rely on visual recognition and natural language prompts, not hard-coded locators.
- ●Recovers from exceptions: If a page loads slowly or an unexpected state appears, agents can pause, retry, or ask for clarification.
- ●Follows the SOP as written: A standard operating procedure in plain English is already almost a prompt. Agents can execute it directly without a separate flowchart.
- ●Works on legacy and Citrix: Because agents move a mouse and type like a human, they function on virtualized and thin-client environments where traditional RPA often fails.
- ●Controls real desktops, browsers, and terminals: Coasty’s agents run on cloud VMs or desktop apps, not just API integrations.
Traditional RPA breaks when the UI changes. Computer use agents survive UI changes by seeing the screen and following the SOP directly.
How to move without the risk
Do not rip out your entire RPA estate in one go. Start with one process that is high pain but manageable: a recurring, SOP-driven task with frequent UI changes or complex exception handling. Identify a process that is currently run manually because the bot is too brittle. Build a prompt that mirrors the written SOP. Deploy a pilot on Coasty and run it alongside the existing RPA bot for a few weeks. Compare uptime, maintenance effort, and time saved. Because agents adapt to UI shifts, you should see fewer rebuilds and faster exception handling. Once you have clear metrics, expand to additional high-pain processes. Keep your stable, high-volume backend RPA where it works well. Use computer use agents for the long tail of changing UIs and exception-heavy workflows. This phased approach lets you escape vendor lock-in gradually while preserving the automation you already have.
