Hermes Agent on Hostinger VPS with Slack and Obsidian

A production-ready deployment of Nous Research's Hermes Agent on a Hostinger KVM-2 VPS, connected to Slack as the primary messaging interface and bidirectionally synced with a local Obsidian vault via Syncthing. The agent runs 24/7 in a Docker container, powered by Claude Sonnet 4.6 via the Anthropic API.

What It Is

This is an always-on AI assistant (named "Slater" in this reference deployment) that you message through Slack like a coworker. It can read, search, and create notes in your Obsidian knowledge base, execute terminal commands, browse the web, and learn from its own interactions through Hermes's self-improving skill system.

The setup connects three systems:

• Hermes Agent running inside a Docker container on a VPS
• Slack as the conversational interface via Socket Mode (no inbound ports needed)
• Obsidian vault synced bidirectionally between your local machine and the VPS using Syncthing

Who It's For

Developers or knowledge workers who want a persistent AI agent they can message from anywhere, with access to their personal knowledge base. You should be comfortable with SSH, Docker, and basic Linux administration.
