From Proxy to Gateway: Managing Multi-Tenant Webhooks on Localhost
IT InstaTunnel Team Published by our engineering team Sharing your local API with three different external services? Stop writing custom routing logic in your app. Learn how to use a Local API Gateway tunnel to authenticate and route webhooks before they hit your code. In modern development, building software rarely means writing isolated code. Today’s applications orchestrate AI agents, process payments via Stripe, and push real-time notifications to Slack — all simultaneously. Every one of these external services needs to talk back to your local development environment via webhooks. Historically, this created a significant bottleneck. Developers would open a single local tunnel, point all third-party services at one endpoint, and write messy routing and authentication logic directly into their application to sort incoming traffic. That approach is dead. The simple reverse proxy has evolved. Enter the Local API Gateway — a sophisticated, multi-tenant tunnel that fundamentally c...
