You have a bot farm running day and night, churning through a forest of legacy apps and portals. Every time the finance team updates a payroll screen, the HR team deploys a new onboarding portal, or IT refreshes a CRM, your bots break. The developer queue grows. The team spends more time patching than building. Meanwhile, the SOPs for these workflows sit in SharePoint, ignored because the bots can’t follow written instructions. Your automation budget is consumed by maintenance, not value.
Why RPA breaks here
Traditional RPA binds to precise selectors, XPath, or object IDs. When the UI shifts even a few pixels, the selector fails and the bot halts. A developer must re-record or rebuild the step, costing hours per change. Across a large bot farm, that cost compounds. Industry benchmarks show that 60, 70 percent of RPA maintenance time goes into rebuilding bots after updates, not into new automation. Exceptions are worse: a single unexpected popup can stop an entire run. When the bot halts, a human must intervene. That downtime is real and expensive.
What changes with computer use agents
- Sees the screen like a human and acts by moving the mouse, clicking, and typing.
- Survives UI changes without needing brittle selectors or object IDs.
- Handles unexpected exceptions by reading the screen and choosing an alternative path.
- Follows an SOP written in plain English directly, with no flowchart bot to build and babysit.
- Works across any app, including legacy systems, Citrix, and virtualized desktops where traditional RPA struggles.
Selectors vs. seeing the screen. Rebuild-on-change vs. adapt. Halt-on-exception vs. recover.
How to move without the risk
You do not have to rip out all RPA at once. Start with one high-pain process where UI changes frequently or exceptions are common. Map it to a written SOP. Run a pilot with Coasty agents on the same data and compare uptime, exception handling, and time to complete. When the pilot shows durable performance, expand to related processes. Keep any high-volume, stable backend tasks on your existing RPA platform. Over time, shift the rest to computer use agents. This phased approach gives you real metrics without overnight disruption.
The durable path beyond bot farms
Computer use agents turn SOPs into executable workflows. They control real desktops, browsers, and terminals, not just API calls. Coasty agents have demonstrated industry-leading performance on public benchmarks, achieving 85.6 percent on OSWorld from our in-house model and 82.81 percent on the official leaderboard at osworld-v1.xlang.ai. They support cloud VMs, a desktop app, agent swarms for parallel execution, a /v1 computer use API, an MCP server, BYOK, and a free tier to start. Use them to run processes that previously required human intervention or brittle RPA bots.
You can decommission your RPA bot farm without downtime by moving to computer use agents that see the screen and follow SOPs. Book a demo with the Coasty team to see how agents can replace unstable bots and scale your automation on your own terms at https://cal.com/coasty/15min .
