The honest brief
Inngest
Durable, resumable functions with no message queue or worker pool for you to stand up and operate.
- Durable execution, automatic retries
- Pause/resume + fan-out + scheduling
- TypeScript-first, framework-agnostic
- Local dev server included
- Smaller ecosystem than Temporal
- Best fit TS/JS; other langs newer
- Hosted tier cost at high event volume
Vercel AI SDK
The de facto TypeScript AI SDK: provider-agnostic streaming and useChat hooks make swapping LLMs a one-line change.
- Provider-agnostic, swap models in one line
- React hooks (useChat) for chat UIs
- Generative UI / structured outputs
- Free and open source
- First-class Next.js integration
- TypeScript/JS ecosystem only
- Lighter on agent orchestration
- Tied to Vercel's release cadence
