Production monitoring for solo founders. $0/month. No excuses.
CTO Cockpit — traffic-light semaphores, incident log, morning sync |
System Dashboard — live metadata from Supabase via n8n |
A complete CTO-grade operations dashboard and automation pipeline that runs entirely on free tiers. Built by a solo founder who got tired of paying for monitoring tools that did less than what she could build in a weekend.
Monitors n8n workflows, Slack channels, GitHub repos, Cloudflare, LinkedIn, and Meta — with traffic-light semaphores, incident tracking, and a 60-second morning sync. Ingests content automatically via webhook, classifies it with Claude AI, cross-links related entries, and builds a searchable metadata layer in Supabase. Ships as a PWA you can pin to your phone and open at 7am to know exactly what's broken (and what isn't).
This is the real system. Not a demo. Open-sourced so other solo founders don't have to build it from scratch.

Total: $0/month (Claude API optional — disable the classify step to stay fully free)
- 🟢 Traffic-light semaphores — green/yellow/red status for every service at a glance
- ⚡ Auto-ingestion pipeline — webhook receives content, Claude classifies it, Supabase stores it
- 🤖 AI classification — Claude API extracts tags, entities, narrative role, timeline group
- 🔗 Cross-linking engine — related entries automatically linked by semantic similarity
- 📅 Narrative timeline — content clustered by time period and narrative arc
- 📱 PWA mobile-first — install to home screen, offline-capable service worker
- 🌑 Dark cockpit theme — monospace, #0a0a0a background, easy on eyes at 7am
- ☁️ Zero-infrastructure — no servers to manage, no Docker, no DevOps
You'll have a working dashboard in under 30 minutes.
# Fork on GitHub, then:
git clone https://github.com/YOUR_USERNAME/zero-cost-ops.git
cd zero-cost-ops- Create a free account at supabase.com
- Create a new project (choose EU region for GDPR if relevant)
- Go to SQL Editor and run
schema/supabase-schema.sql - Copy your project URL and anon key from Settings > API
- Create a free account at render.com
- New > Web Service > Docker
- Use image:
n8nio/n8n:latest - Set environment variables:
N8N_BASIC_AUTH_ACTIVE=true N8N_BASIC_AUTH_USER=admin N8N_BASIC_AUTH_PASSWORD=your-secure-password SUPABASE_URL=https://YOUR-PROJECT.supabase.co SUPABASE_SERVICE_ROLE_KEY=your-service-role-key - Note your Render URL:
https://your-n8n.onrender.com
- In n8n, go to Workflows > Import from File
- Import
workflows/WF-01-ingestion-pipeline.json - Import
workflows/WF-04-timeline-engine.json - Update Supabase credentials in each workflow
- Activate both workflows
Edit dashboard/system-dashboard.html — find the API constant and update:
const API = 'https://YOUR-N8N-INSTANCE.onrender.com/webhook/system';Edit dashboard/cto-cockpit.html — update the CONFIG object with your services.
- Go to your repo Settings > Pages
- Source: Deploy from a branch > main > / (root)
- (Optional) Add custom domain via Cloudflare
Render free instances sleep after 15 minutes of inactivity. Add a UptimeRobot monitor to ping your n8n health endpoint every 5 minutes:
https://YOUR-N8N-INSTANCE.onrender.com/healthz
That's it. Your CTO cockpit is live.
What it does: Receives content via webhook → filters noise → classifies with Claude AI → stores in Supabase → triggers cross-linking.
Webhook → Extract Content → Filter → Claude Classify → Parse → Supabase Insert → Trigger WF-02 → Respond
Inputs: Any POST to /webhook/wf01-ingest with { text, source, user_id }
Output: Classified entry in Supabase metadata table with tags, entities, narrative role, and timeline group
Claude model: claude-sonnet-4-20250514
What it does: Scans all entries in Supabase → clusters by time period → detects narrative arc patterns → updates timeline_group field in bulk.
Webhook → Fetch All → Temporal Clustering → Narrative Arc Detection → Batch Update → Summary
Run: Trigger manually or on a schedule (weekly recommended)
Output: All entries tagged with 1974-1990 | 2019-2023 | 2024-2026 + narrative role analysis
See workflows/README.md for detailed documentation.
This system is designed to be adapted, not just deployed. You can:
- Change monitored services — edit the
CONFIGobject incto-cockpit.html - Add new workflows — follow the same pattern as WF-01 (webhook → process → Supabase)
- Modify the schema — add columns to
metadataor create new tables - Replace Claude — swap the HTTP request node for any other LLM API
- Add authentication — Supabase Auth is already configured in the schema
See docs/CUSTOMIZATION.md for a full guide.
