Build & Deploy a Full Stack Autonomous AI Agent SaaS (Like OpenClaw) - Next.js, React, Claude

⭐️⭐️ ⭐️  Free Cheatsheet (with Github Source Code): https://dub.sh/execos-cheatsheet

⭐️⭐️ ⭐️  Huge Shoutout to Clerk for sponsoring this build: https://go.clerk.com/rDCSPyr (make sure to check them out here)

We're building Exec OS, a full-stack AI SaaS that runs autonomously using the same architecture as OpenClaw, powered by Next.js 16, React 19, and the Vercel AI SDK with Claude API. This autonomous AI agent runs on a 15-minute heartbeat, triaging your inbox, ghostwriting email drafts, scheduling calendar events, and generating action items all without you lifting a finger.

Whether you're looking to build an AI side hustle or a full-scale AI agency, this is your 2026 blueprint. 

The entire tech stack costs $0 to start.
