Inngest

Inngest is a Background Functions and Workflows Platform already used by 10,000 Next.js developers, including Resend.

Whether you're building integrations, AI workflows, or feature-specific workflows (e.g., email campaigns), Inngest has you covered with its low-latency workflow engine, which handles over 100 million daily runs.

All this while benefiting from Vercel’s platform:

• Designed for Next.js: Write Functions directly from your app/ directory and run them locally with our Dev Server.
• Preview environment ready: Move to production smoothly with branching support
• One-click install and a generous free tier: up to 50K runs per month included
