YC Startup

Event CoreCoasty (YC S24/S26) has officially launched a specialized API for "Computer-use Agents." This infrastructure allows developers to run and control cloud-hosted browsers or full desktop environments, enabling AI to perform human-like actions such as clicking, typing, and navigating complex interfaces. The goal is to empower AI agents to interact directly with existing software UIs, bypassing the limitations of traditional API-based integrations.Key Takeaways▶ UI-as-an-API: Coasty transforms graphical user interfaces into programmable endpoints, unlocking automation for legacy software and platforms that lack native API support.▶ Infrastructure Abstraction: By providing managed, sandboxed environments, Coasty removes the heavy lifting of VM orchestration, latency optimization, and session management for developers.▶ Human-Centric Interaction: The platform leverages Vision Language Models (VLMs) to simulate authentic human inputs, enabling agents to handle dynamic web elements and cross-application workflows seamlessly.Bagua InsightFollowing Anthropic's "Computer Use" breakthrough, the industry is shifting from "LLM as a Thinker" to "LLM as a Doer." Coasty is positioning itself as the essential plumbing for this new paradigm—essentially the "Stripe for Computer Use." While big tech focuses on the models, Coasty is winning on the execution layer by offering a vendor-agnostic, scalable environment. This move signals the beginning of the end for traditional, rigid RPA. We anticipate a future where software value is measured by its "Agentic Accessibility"—how easily an AI can navigate its interface without human intervention.Actionable AdviceFor Enterprise Architects: Revisit automation backlogs that were previously deemed impossible due to missing APIs. Tools like Coasty provide a non-invasive path to automating legacy workflows.For Developers: Focus on building robust "visual feedback loops." Prioritize infrastructure that offers high-fidelity UI rendering and low-latency execution to ensure agent reliability.For SaaS Product Managers: Prepare for a "Headless UI" world. Ensure your web and desktop interfaces are semantically rich and easily interpretable by computer-vision-based agents to maintain relevance in the agentic ecosystem.
