What should I use to build a webhook listener service?

For a webhook listener service, the best choice depends on your traffic, language preference, and how much reliability/ops work you want to manage.

Good common choices

• Node.js / TypeScript (Express, Fastify, NestJS)

  • Great if you want fast development and lots of webhook-related ecosystem support.
  • Fastify is a strong pick for performance.
  • NestJS is good if you want a more structured, enterprise-style app.

• Python (FastAPI, Flask)

  • FastAPI is excellent for modern async APIs and easy validation.
  • Good if your team already uses Python.

• Go (net/http, Gin, Fiber)

  • Best when you want high throughput, low latency, and simple deployment.
  • Very good for always-on webhook receivers.

• Serverless options

  • AWS Lambda + API Gateway, Cloudflare Workers, Google Cloud Functions, Azure Functions
  • Great if traffic is spiky and you want minimal infrastructure.
  • Beware of cold starts and provider limits if webhooks require quick acknowledgments.

What matters most for webhook listeners

Regardless of stack, make sure it supports:

• Fast response times (usually respond 200 OK quickly)
• Signature verification (HMAC, JWT, etc.)
• Retry-safe/idempotent processing
• Queueing/background jobs for slow work
• Logging and observability
• Rate limiting and replay protection

My practical recommendation

• If you want the safest general-purpose choice: Fastify (Node.js/TypeScript) or FastAPI (Python).
• If you expect high volume or want a very lean service: Go.
• If you want low ops and event-driven scaling: serverless.

If you tell me your expected traffic, cloud provider, and preferred language, I can recommend a specific stack and architecture.
