Asteroid is a full-stack platform that enables both non-technical users and engineers to build, run, and optimize computer-use AI agents for browser, Linux, and Windows environments. The product focuses on repeatable, mission-critical workflows rather than one-off tasks, emphasizing reliability over breadth. It addresses the challenge of automating systems that lack APIs by leveraging advanced LLMs like Claude Opus 4.6+ to create reliable computer-use agents. The platform supports any interaction mode including visual computer use, structured DOM, or scripted execution across browser, Linux, and Windows desktop environments. It includes a meta-agent called Astro that builds and debugs agents automatically, writes scripts during execution, and makes repeat runs faster and cheaper. Each agent receives a persistent filesystem to store scripts, files, and memories for reuse across runs, along with session persistence to stay signed in and resume where left off. Additional features include dedicated email inboxes for 2FA and notifications, proxy support for stealth browsers and VPNs, live view and recordings with human-in-the-loop checkpoints, and API-first architecture with webhooks, MCPs, and SDKs. Asteroid operates on the principle that it's better to automate 50 complex browser portals extremely reliably than 1,000 at surface level. The platform combines frontier LLMs from OpenAI, Anthropic, Google, and others with enterprise-grade security including HIPAA and SOC II Type II certification. It provides comprehensive tooling for deployment at scale across critical industries, with built-in audit trails and compliance features essential for healthcare and insurance use cases. The platform is designed for production deployment across startups and enterprises, with over 150,000 executions completed last month alone. It handles complex scenarios including EHRs, benefits portals, insurance carriers, Citrix environments, desktop applications, and VPN-protected systems. The focus on repeatable workflows makes it particularly valuable for organizations with ongoing automation needs rather than one-time tasks. Primary use cases include healthcare interoperability challenges such as EHR and patient record extraction, voice-to-form clinical intake, health insurance enrollment, patient creation and scheduling. Insurance industry applications include policy management, quoting, renewals, endorsements, and claims submission. The platform also supports intelligent scraping across thousands of venue calendars and form filling for government portals, banking dashboards, and internal finance tools.
