Pros & Cons

✓ Pros

✓Durability is built in — agents survive crashes, restarts, and long waits
✓TypeScript-first with strong typing on tools, state, and events
✓Excellent local dev experience via Inngest dev server
✓MCP, E2B, Browserbase, and Smithery integrations land out of the box
✓Open source framework; you only pay for the Inngest runtime if you use Inngest Cloud

✗ Cons

✗TypeScript only — Python teams should look at /tools/crewai or /tools/autogen
✗Tied to Inngest's execution model; learning curve if you don't already use Inngest
✗Smaller ecosystem and fewer prebuilt agents than LangChain
✗Agentic router patterns still need careful prompt design to avoid loops
✗Self-hosting Inngest is possible but operationally heavier than the Cloud tier
