Overview

A runtime platform where developers define AI agent workflows as TypeScript functions — Lumen persists every step, survives crashes, and deploys globally with a single CLI command. Built-in observability with per-step traces, replays, and cost attribution.

My role

Full-stack — runtime design, landing page, chat UI, deployment

Highlights

  • 01

    Durable execution — workflows survive crashes and resume from any step automatically

  • 02

    Per-step observability with traces, replays, and token cost attribution

  • 03

    One-command deploy (`lumen deploy`) — no Docker, no Kubernetes

Key features

  • Three primitives: durable workflows, inspector, and global deployment target
  • First-class AI agent loops with built-in tools and memory support
  • Interactive chat UI for workflow interaction
  • BYOC (Bring Your Own Cloud) for enterprise — run in your own AWS/GCP/Azure
  • Three-tier pricing with a generous free tier (10k step executions/mo)
