Build browser, Linux, and Windows AI agents in seconds
No-code computer-use agent builder — describe the workflow and Astro, Asteroid's meta-agent, constructs and debugs the agent autonomously, producing reusable scripts you can hand off. Targets messy real-world automation: EHRs, insurance portals, desktop apps, VPN-protected systems. API-first with webhooks, MCPs, SDKs, persistent sessions, and human-in-the-loop checkpoints.

OpenAI's official Chrome extension that lets Codex navigate web pages and complete multi-step tasks directly in the browser — fill forms, scrape data, drive web apps without copy-pasting between tabs. Browser-native agents are the new assistant battleground, and this is the most polished option for ChatGPT users who want their AI to actually do the work rather than just describe it.
Open-source browser automation built on Bun rather than Node, with an API designed for AI agent workflows from the ground up. Faster startup and lower memory overhead than Puppeteer or Playwright when spinning up disposable browser sessions for agents to drive — useful for any developer building autonomous web tasks at scale.
Schedules recurring AI agent runs with one command and zero infrastructure — no servers, queues, or wrappers required. The plumbing layer for anyone running agents that need to wake up on a schedule rather than only on a user prompt, which covers most production agent use cases once you move past chat.
