Practical guides
Step-by-step guides for running AI agents, local models and RAG on your own VPS. Working commands, not theory.
How to host Claude Code on a persistent VPS
Run Claude Code on your own Linux VPS so your AI coding agent stays alive 24/7 — install Node.js, the CLI, your API key and keep it running in tmux.
Running an OpenClaw backend on your VPS
Self-host OpenClaw on your own VPS: clone the repo, run it with Docker Compose, point it at your model of choice and connect Telegram, WhatsApp or Discord 24/7.
Local LLM vs API: which to run on your VPS
Should you run an open-weights model locally on your VPS or call a frontier API? Compare cost, privacy, capability and hardware to pick the right approach.
Self-hosting a RAG vector database (ChromaDB & pgvector)
Host your own RAG vector store on a VPS. Set up ChromaDB or PostgreSQL with pgvector, persist the data and keep it private behind Tailscale.
GDPR-compliant AI hosting in the EU (Estonia)
How to keep AI workloads GDPR-compliant: EU data residency, full data control, local models that keep data on-server, and what to watch for with external APIs.
Securing a VPS for AI agents (UFW + Tailscale + SSH)
Harden a VPS that runs AI agents: SSH key-only login, a default-deny firewall, private access over Tailscale, fail2ban and automatic security updates.
