Cross-client monitoring for n8n and Make — and the white-label monthly report you send the client.
Built for people who run automations for other people. Connect every client's n8n instance in one place, get failures explained in plain English, and generate a per-client monthly report you can put your own logo on.
If you run automations for clients, you have two recurring problems:
- A client's workflow breaks at 3 AM and you find out when they email you.
- At month-end the client asks what the retainer bought — and the honest answer is "a lot of things quietly not breaking," which is impossible to invoice against.
Uptime pingers solve a slice of #1 (they tell you a job stopped checking in). FlowWatch reads n8n's execution data, so it knows which workflow failed and why, and it turns a month of that data into a document your client actually reads.
- Connects clients two ways — poll the n8n REST API with an API key, or drop a webhook URL into an Error Trigger node. Make scenarios use the same webhook.
- Explains failures in plain English with a suggested fix (rule-based; optionally sharper with an Anthropic API key). Repeat failures are throttled so a flapping workflow can't bury you.
- Tracks incidents — one open incident per workflow, auto-resolved when the next run succeeds.
- Alerts to Discord instantly, plus a daily digest across every client.
- Generates a white-label monthly report per client at an unguessable URL: executions, success rate, per-workflow breakdown, incidents with resolution times, estimated hours saved, optional AI spend. Your agency name and logo; no FlowWatch branding anywhere on it.
Requires Node 22+ (uses node:sqlite). Zero npm dependencies.
git clone https://github.com/retrocodes12/flowwatch.git
cd flowwatch
npm test# 158 tests, no install step needed
npm run simulate # seeds two demo clients and prints their report URLs
ADMIN_TOKEN=changeme npm startThen open http://localhost:8790/dashboard?token=changeme.
npm run simulate gives you a realistic 30-day book of business so you can see the
dashboard and reports populated before connecting anything real. Demo clients render
with a visible "sample data" ribbon.
Set these in a .env file (loaded automatically) or the environment:
| Variable | What it does | Default |
|---|---|---|
ADMIN_TOKEN | Required to reach the dashboard. Unset = admin routes 404. | — |
PORT | HTTP port | 8790 |
DB_PATH | SQLite file | ./data/flowwatch.db |
AGENCY_NAME | Name on client reports | Your Agency |
AGENCY_LOGO_URL | Logo on client reports | — |
AGENCY_BRAND_COLOR | Report accent colour | #3b5bdb |
DISCORD_WEBHOOK_URL | Where alerts go. Unset = dry-run to stdout. | — |
DIGEST_HOUR | Local hour (0–23) for the daily digest | 9 |
POLL_INTERVAL_SECONDS | How often n8n instances are polled | 300 |
ANTHROPIC_API_KEY | Optional: better failure explanations | — |
ANTHROPIC_MODEL | Model for explanations | claude-opus-4-8 |
- Add the client on the dashboard.
- Add a source:
- n8n API — paste the instance base URL and an n8n API key. Workflows and executions are discovered automatically.
- Webhook — copy the generated
/hooks/<token>URL into an n8n Error Trigger node (or a Make error handler).
- Optionally set minutes saved per run per workflow — this drives the "hours saved" figure on the report. Leave it at 0 and the report simply omits the claim.
- Share the client's report link:
/r/<report_token>/<YYYY-MM>.
- One agency per deployment. No multi-tenancy, no signup, no billing code. Run one instance per agency (pm2, Docker, whatever) and keep each agency's data physically separate.
- Zero dependencies —
node:http,node:sqlite,node:cryptoonly. No supply chain, nonpm install, no lockfile drift. - Reports never show a number the product can't compute. Hours saved comes from values you set; AI spend only appears if you enter it. Nothing is invented.
- Admin routes and unknown tokens return byte-identical 404s (no existence oracle); tokens are compared in constant time; webhook bodies are capped at 256 KB.
Issues and PRs welcome. Things that would genuinely help:
- More platforms (Zapier, Activepieces, Windmill)
- Slack alerts alongside Discord
- Emailing the monthly report to the client directly
- Better failure-explanation rules from real-world n8n errors
