Ask HN: What do you run on a $5 VPS that's worth keeping online 24/7?

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Four prevalent themes in the discussion about cheap VPS usage

  1. Self‑hosting personal productivity and media services
    Users frequently run apps like Immich, Jellyfin, Plex, Vaultwarden, Gitea, RSS readers, and note‑tools on their VPS to keep data private and avoid reliance on big tech.

    “Self hosting my photo albums. Immich is a handy choice for this. Very useful for personal photos you don't want to trust to strange tech companies.” – ehe78qhe
    “I have a few thousand Linux ISOs on there… I keep them all. Compression algorithms are pretty good these days, as is storage density.” – ehe78qhe (the “Linux ISO” talk often doubles as a euphemism for personal media archives).

  2. VPN / networking infrastructure (Tailscale, WireGuard, DNS, email, exit nodes)
    Many treat the VPS as a gateway for secure remote access, censorship circumvention, or basic internet services.

    “Deploy a vpn” – Sha1rholder
    “Exit node for friends in countries with internet censorship.” – andOlga
    “I run a language learning app on a single VPS… I installed Plex but ended up not using it…” – sebbun (shows mixing VPN‑like tunneling with app hosting).
    “Deploy email server on a vps is super risky and troublesome” –     Sha1rholder* (reflects the ongoing debate about self‑hosted mail).

  3. Experimentation, learning, and sysadmin practice
    The low cost makes the VPS a sandbox for trying new tech, hosting dev environments, or running bots without fear of breaking production systems.

    “After getting into home assistant and setting up a proper home server I no longer saw a need to keep the VPS running… hosting your own stuff provides a great place to learn and explore.” – jbarberu
    “I use mine as basically an open test server I can play with.” – AndrewKemendo
    “I run a discord bot for my dota2 guild, works well, deployed as a container.” – keithnz

  4. Off‑site backup, redundancy, and long‑term archival
    Users mirror GitHub repos, store backups, or keep media archives on the VPS as a safety net against local hardware failure or service shutdowns.

    “Mirror my Github repos (in case GH goes down or closes my account)… Occasionally use it as a WeTransfer alternative.” – grugdev42
    “I have an rclone job running regular encrypted offsite backups as well, so that my Linux ISOs are safe from hardware issues.” – ehe78qhe
    “I also have another one of a similar price coloated in Luxembourg, for reasons which are legal in Luxembourg.” – ivraatiems (geographic redundancy).

🚀 Project Ideas

Self-Hosted Email Relay with Reputation Management

Summary

  • A Docker‑based toolkit that automates Postfix/Dovecot setup on a cheap VPS, adds DKIM/SPF/DMARC, warm‑up scheduling, and real‑time reputation scoring to solve deliverability fears.
  • Core value: run a private/family email server with confidence, reducing spam‑folder risk and eliminating reliance on third‑party providers.

Details

Key Value
Target Audience Individuals/families wanting personal email on a $5‑$10 VPS
Core Feature One‑click deploy with reputation monitoring, alerts, and automated DNS records
Tech Stack Docker, Postfix/Dovecot, OpenDMARC, Python (reputation checker), CoreOS‑aligned scripts
Difficulty Medium
Monetization Hobby

Notes

  • HN users expressed anxiety about email deliverability and IP reputation (e.g., "Lammy: Luck of the draw due to IP address reputation").
  • Provides a discussion‑worthy open‑source alternative to managed email services, encouraging self‑hosting education.

Encrypted Personal Knowledge Base & Sync

Summary

  • A lightweight, end‑to‑end encrypted note‑taking service (web + mobile) that stores notes in an encrypted SQLite DB and syncs via self‑hosted WebDAV or a simple REST API.
  • Core value: keep personal notes, ideas, and documents private and accessible from anywhere without trusting SaaS providers.

Details

Key Value
Target Audience Privacy‑conscious individuals seeking a self‑hosted notebook
Core Feature E2EE note sync with full‑text search, tagging, and markdown preview
Tech Stack Go/Rust backend, Svelte/React frontend, SQLite + libsodium encryption, Docker
Difficulty Medium
Monetization Hobby

Notes

  • Commenters like "jedberg" regretted not having offsite backups for photos; this idea extends that concern to personal knowledge.
  • Sparks conversation about alternatives to proprietary note apps and the feasibility of strong encryption on low‑cost VPS.

WireGuard Home‑Gateway Assistant

Summary

  • A script that installs and configures WireGuard on a VPS to act as a persistent relay for home networks behind CGNAT, with automated client config generation (QR codes) and optional exit‑node toggling.
  • Core value: give users reliable remote access to home services and bypass geo‑blocks without paying for commercial VPNs.

Details

Key Value
Target Audience Home users with dynamic IPs or CGNAT who need remote LAN access
Core Feature Zero‑touch WireGuard server with monitoring, auto‑updates, and easy client provisioning
Tech Stack WireGuard, systemd, Go (API/cli), Cloudflare API for DNS optional, Docker
Difficulty Low-Medium
Monetization Hobby

Notes

  • Many users (e.g., "mtlynch", "hackernud3s") wanted VPNs for Jitsi or geo‑unblocking but worried about complexity; this simplifies it.
  • Enables practical utility: exposing Home Assistant, Immich, or personal files securely from anywhere.

Multi‑Target Offsite Backup Orchestrator

Summary

  • A web‑managed service that runs Restic/Kopia backups from a VPS to multiple low‑cost storage backends (B2, Wasabi, Hetzner Storage Box) with encryption, scheduling, verification, and alerting.
  • Core value: eliminate the fear of data loss by providing a unified, verifyable offsite backup pipeline for self‑hosters.

Details

Key Value
Target Audience Self‑hosters running personal services (photos, git, notes) who need reliable offsite backups
Core Feature Central UI to define backup jobs, retention policies, and get email/webhook failure notices
Tech Stack Python (FastAPI/Restic), Docker, PostgreSQL for job metadata, MinIO‑compatible SDKs
Difficulty Medium
Monetization Revenue-ready: $2‑$5/mo per VPS for premium monitoring & support (open‑source core)

Notes

  • Users such as "Footprint0521" and "jedberg" lamented lacking offsite backups and feared hardware failure or ransomware.
  • Generates discussion on backup best practices and could become a go‑to tool for the homelab community.

Personal Dashboard & Life Metrics Aggregator

Summary

  • A low‑resource web dashboard that pulls data from APIs (finance, fitness, weather, server metrics, GitHub, RSS) and displays configurable widgets, with a simple plugin system for custom scripts.
  • Core value: give individuals a centralized “ops center” to monitor personal health, productivity, and infrastructure without relying on multiple SaaS dashboards.

Details

Key Value
Target Audience Power users who enjoy self‑hosting and want a unified view of personal data
Core Feature Modular widget framework with drag‑drop layout, data source connectors, and optional custom JS/Python plugins
Tech Stack Node.js (or Python) backend, React/Vue frontend, SQLite for caching, Docker
Difficulty Medium
Monetization Hobby

Notes

  • Commenter "chr15m" described a personal daily updating dashboard with life metrics, showing demand for such a tool.
  • Encourages sharing of widget plugins and discussion about privacy‑friendly alternatives to Google Dashboard or Notion.
