# Application testing

Last validated May 18, 2026

Tailscale streamlines application testing workflows by letting developers share local services with teammates, expose servers to the public internet for webhook testing, and route traffic through global exit nodes for localization testing — all without complex cloud deployments or network configuration.

## Popular workflows

[**Localization and geo-specific testing by simulating traffic from different global locations**](/docs/use-cases/application-testing/geo-specific-testing) — Use Tailscale exit nodes to route test traffic through different geographic locations and validate localization behavior with Siege.

[**Share a local development server with the internet**](/docs/use-cases/application-testing/share-local-dev-server-with-internet) — Use Tailscale Funnel to expose a local development server to the public internet over HTTPS, without configuring port forwarding or a public IP address.

[**Share a local development server with your team**](/docs/use-cases/application-testing/share-local-dev-server-with-team) — Use Tailscale Serve to expose a local development server to other members of your tailnet over HTTPS, without opening access to the public internet.
