Practical overview

When it fits

Use hostd when you intend to operate storage-host infrastructure on Sia and want a self-hosted web interface and API for host management.

Who it is for

  • Individual Sia storage providers operating their own host.
  • Larger-scale providers who need a web interface or API to manage host resources and revenue.

Documented uses

  • Manage a Sia host’s storage resources and revenue.
  • Configure the host’s data directory, network synchronization, and consensus settings.
  • Choose RHP4 connection transport using SiaMux over TCP or QUIC over UDP.
  • Access host controls through the embedded web UI or API.
Before you choose

Requirements & limits

hostd is open-source software under the MIT license and is self-hosted.

  • The README recommends YAML configuration and documents an interactive configuration-generation command.
  • The UI and API use TCP port 9980 by default; the README advises Docker users to bind it to 127.0.0.1 unless public exposure is intended.
  • RHP4 can use SiaMux over TCP or QUIC over UDP.
  • Instant syncing is experimental and requires a wallet with only v2 history.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
