Networking

Networking in Hostim.dev connects your apps to the outside world and to each other. Each app can be accessed via a public domain, and services within the same project can communicate internally.

This section covers:

  • Custom domains and SSL for external access
  • Internal routing for secure communication between services
  • Outgoing IP addresses for allowlisting on third-party services

Public access​

Every app gets a default subdomain provided by Hostim. You can also attach your own domain and Hostim will automatically issue an SSL certificate.

Internal communication​

Apps and services inside the same project can talk to each other using internal hostnames. This allows for secure, low-latency connections without exposing traffic to the public internet.

Outgoing traffic​

When your app connects to external services, it will use one of our dedicated outgoing IP addresses. You can use these to allowlist Hostim in your firewall or third-party service settings.

Typical use cases​

  • Route traffic to a web frontend via a custom domain
  • Let a backend app connect to a database or Redis service privately
  • Connect microservices using internal hostnames

Networking is built-in and requires no manual configuration.
