10 creative, feasible projects for a 2 vCPU / 4 GB RAM VPS running OpenClaw. Every stack choice is RAM-conscious and production-tested.
1. LinkVault — Self-Hosted Bookmark Saver
LinkVault
personal cloudRAM: ~600MB1 CPU
"A self-hosted bookmark & read-later service with AI-powered summarization."
Save links from anywhere, automatically fetch metadata, generate summaries via local LLM, and tag/organize with AI assistance. Think Pocket meets local AI — fully self-hosted.
MVP: Save URL → fetch title/description → basic list view. No summarization yet.

2. PulseRSS — AI Daily Digest
PulseRSS
data aggregationRAM: ~400MB1 CPU
"Your own RSS aggregator with daily AI digest emailed to you."
Aggregate all your RSS feeds in one place, detect new articles, use local LLM to generate a crisp daily digest email so you wake up informed. Fully autonomous once set up.
MVP: Parse 5–10 feeds, list new articles, raw feed output. AI digest is stretch goal.

3. WhisperBox — Voice Transcription Hub
WhisperBox
personal AIRAM: ~700MB1 CPU
"Voice note transcription hub — drop audio, get text."
A web interface to upload audio files which are then transcribed via Whisper.cpp (CPU-based, no GPU needed). Transcripts stored searchable in SQLite. Great for voice memos, meeting notes, voice diaries.
MVP: Upload mp3/wav → transcribe → display text → search transcripts. Run stand-alone (not alongside Ollama) to fit RAM.

4. Nomad Board — Travel Tracker
Nomad Board
personal cloudRAM: ~300MB1 CPU
"Travel tracker that plots your countries and cities on a map automatically."
Log visits manually or pull from Google Photos EXIF data, maintain a personal travel log, render a world map showing visited places. No account needed, fully offline-first.
MVP: Manual city/country entry → list view of visits → basic world map via Leaflet.js.

5. AutoGrok — Topic Monitoring Agent
AutoGrok
automationRAM: ~800MB2 CPU
"A personal agent that monitors topics and drafts responses for your review."
Track keywords/topics across RSS feeds, Twitter/X via API, and Reddit. When relevant content appears, use local LLM to generate a draft reply/tweet/comment for you to review and post. Your digital twin that never sleeps.
MVP: Track 3 keywords across 5 RSS feeds → store matches in DB → show in web UI for review. No Twitter integration yet.

6. PaperTrail — Personal Knowledge Base with AI Q&A
PaperTrail
personal AIRAM: ~700MB1 CPU
"A lightweight personal knowledge base with markdown and local AI Q&A."
Write and store markdown notes, organize by tags, and query your knowledge base using a local LLM that reads only your notes. No cloud, no tracking, completely private.
MVP: Create/edit/delete markdown notes → tag-based search → basic chat-Q&A over notes via Ollama.

7. WatchDog — Uptime & SSL Monitor
WatchDog
monitoringRAM: ~200MB1 CPU
"Uptime & SSL monitoring dashboard that alerts you via Telegram."
Monitor up to 20 websites/apps for uptime, latency, and SSL certificate expiry. Clean dashboard, alerts via Telegram bot when something goes down. Self-hosted alternative to UptimeRobot.
MVP: Add URLs → check every 5 min → show status page → Telegram alert on down.

8. PastePit — Minimal Self-Hosted Pastebin
PastePit
productivityRAM: ~150MB1 CPU
"A minimal, self-hosted pastebin with burn-after-read and expiry."
Share text snippets, code, and logs with optional expiration and burn-after-read. No account needed. Links are random and unguessable. Similar to PrivateBin but lighter and simpler.
MVP: Paste text → get link → optional 24h expiry → basic list of recent pastes.

Notes
Total RAM
4 GB
Leave ~1 GB headroom for OS and kernel
CPU
2 vCPU
Shared at Bluehost — don't plan on sustained 100%
Storage
Varies per project
Models need SSD storage; spinning disk OK for logs
LLM on VPS
llama3.2 2B only
3B+ needs too much RAM. Embedding models for RAG are lighter
Whisper.cpp
Run solo, not with Ollama
~700MB RAM during transcription. Schedule as standalone job
n8n / heavy automation tools
Avoid
n8n alone needs 1GB+. Use cron + Python scripts instead
SQLite everywhere
Recommended
No daemon RAM overhead. Fine for personal use at this scale
Recommended Stack

Tool
Why
Web framework
Python Flask
Much lighter than Django or FastAPI for single-user tools
Database
SQLite
No daemon. Personal-use concurrent reads are fine
LLM
Ollama + llama3.2 2B
~1.5GB RAM. The only full LLM that fits alongside other services
RAG / embeddings
nomic-embed-text via Ollama
Lighter than full LLM. Semantic search on knowledge bases
Transcription
Whisper.cpp
CPU-only, ~500MB. Run as standalone scheduled job
Bot/alerting
Telegram Bot API
Extremely lightweight, zero-cost, reliable
Scheduling
cron + APScheduler
cron for simple intervals; APScheduler for complex workflows
Frontend
Vanilla JS + HTMX
No React/Webpack overhead. HTMX for reactive elements
