Why

Building a SaaS is a long game, and the numbers that keep you going are buried in a dashboard you rarely open. SaaS Monitor turns your Stripe account into a screen for the office, your desk or a Raspberry Pi behind a TV: the MRR ticks up when a customer subscribes, a cash register rings when a payment lands, and confetti flies when you cross $10K MRR.

Features

• Live metrics: MRR, or ARR if that's how you count, with its 30-day growth; revenue today and this month, customers, net new MRR, and a feed of every new customer, payment, upgrade and churn.
• A history chart over the last 30 days, 90 days, 12 months or all time, with your next goal on its horizon.
• Sounds for every event: payments, new customers, MRR up, MRR down and milestones, in three packs (cash register, chime, arcade) synthesized in the browser.
• A voice that announces them: "New subscriber!", in five languages. With a Gradium key, in your own words, with the customer's name, the amount and the plan.
• Every event your way: for each kind of event, choose whether it is listed in the feed, shown as a card, heard and said out loud.
• Celebrations and goals: confetti, a full-screen moment for each milestone ($1K, $10K MRR…, $1M ARR) or your own goal, with the date you'll reach it at your current pace.
• Made for the wall: scales from a 720p monitor to a 4K TV and portrait screens, never sleeps, recovers from network outages, reloads itself after an update, protects OLED panels.
• Yours: a dark or a light screen, in your brand color (pasted as hex, adjusted if needed to stay readable), speaking English, French, German, Spanish, Italian, Portuguese or Dutch, with numbers and dates written the local way.
• Dead simple settings with a live preview, and a "send a test celebration" button to check the sound on the TV.
• Several Stripe accounts on one screen, converted to your currency: added up, or taking turns every few seconds, each moment naming the product it comes from. Or one screen per product.
• Teams: workspaces, invitations by link, as many screens as you like.
• Honest numbers: MRR follows Stripe's own definition, so the TV matches your Stripe Dashboard.
• Private and secure: read-only restricted keys encrypted at rest, unguessable screen links with an optional password, customer names and emails hidden unless you allow them.
• Real time within Stripe's limits: webhooks for instant updates, and polling that respects Stripe's API read allowance when webhooks aren't available.

Try it

• Live demo: https://saas-monitor.com/d/demo is a screen fed by a simulated SaaS, where something happens every few seconds. No account needed. Add ?theme=light&lang=fr&accent=ff6b35 for a light screen in French and your color, ?accounts=2 for two products taking turns, or ?sound=arcade&voice=marius&range=all&metric=arr for other settings.
• Online: create an account on https://saas-monitor.com, free during the public beta, connect Stripe with a read-only key, and open your screen's link on any TV. Updates are instant.
• On your own server: free for good, see Self-hosting. The demo is at /d/demo there too.

Self-hosting

SaaS Monitor is a Next.js app and a MySQL database. With Docker:

git clone https://github.com/Synapsr/SaaS-Monitor.git
cd SaaS-Monitor
node scripts/setup.mjs      # writes .env with fresh secrets
docker compose up -d        # http://localhost:3000

Create your account, connect Stripe with a restricted key, and open your screen's link on any TV or Raspberry Pi. The self-hosting guide covers configuration, HTTPS (needed for instant updates), updates and backups.

How it works

flowchart LR
  Stripe -- "webhook (instant)" --> App
  App -- "Events API (catch-up, within the read budget)" --> Stripe
  App --> DB[(MySQL<br/>subscriptions · MRR ledger · payments · customers)]
  DB --> Screen["/d/token<br/>polls every 10 s"]

Loading

1. Import: subscriptions and 12 months of payments are imported once, in resumable chunks.
2. Sync: new activity is read from Stripe's Events API when a webhook announces it, or at a pace derived from your read allowance. Every change of MRR is recorded in a ledger, which gives the history chart and the new / expansion / contraction / churn breakdown.
3. Display: screens poll the app every 10 seconds; syncs run on demand, so no background worker is needed and the app runs anywhere Node runs.
