Webhook

Silence Alert — acquisition

"No new signup in 4 hours — at 2am."

Your funnel broke in the middle of the night. Ad spend kept running. Nobody knew until standup. No error fired, no exception was logged — just silence where 8 signups an hour should have been. NotiLens fires within minutes.

Silence Alert — payments

"Stripe payment webhook silent for 3 hours."

Stripe is up. Your server is up. But webhook deliveries stopped arriving — and silent payment failures are compounding right now. Your revenue report will show the damage tomorrow. NotiLens catches the silence today.

CI/CD Alert — deployment

"Deploy broke — users reporting 404s."

Your CI pipeline completed. The deployment silently failed. Users started hitting 404s before your team even knew the release had gone out. The first signal you had was a user DM at 11pm on a Friday.

Loop Detected — AI agent

"AI agent looped — burned $40 in API calls."

Your autonomous agent started cycling with no progress. No output, no completion, no timeout — just an ever-growing API bill discovered the next morning. NotiLens detects loops in real time and stops the bleeding.

Rate Anomaly — support queue

"Support tickets 4× above normal."

Users are filing tickets faster than normal. This is a reliable early signal of a product issue — it shows up in your support queue before it shows in error logs or your analytics dashboard. Act before it becomes a crisis.

The Problem

Startups find out about problems the worst way

You're a small team moving fast. You don't have a 24/7 ops team or a dedicated analytics engineer. You find out something broke when a user tells you — or when revenue drops.

No monitoring budget

Enterprise monitoring tools cost $500/month and take weeks to set up. So you run blind — hoping nothing breaks until you can afford the infrastructure to watch it. NotiLens Pro is $29/month.

Scattered across 10 tools

Stripe for payments, Sentry for errors, CloudWatch for servers, Mixpanel for signups. Nine tabs open, no unified picture, and you only check them when something already feels off.

Found out from a user

"Hey, your signup form seems broken" — the most dreaded Slack message. It worked at 9am. It broke at noon. It's now 4pm and you're still catching up, and you still don't know how many signups you lost.

How NotiLens Helps

Everything you need. Nothing you don't.

NotiLens was built for teams that can't afford to have things break silently. Fast to set up, easy to configure, and built to scale as you grow.

Signup & payment silence alerts

Set expected rates for signups, Stripe events, and any business metric. Get alerted the moment traffic goes quiet — before your ad budget burns unnoticed and before users file tickets.

Broken flow detection

Define two-step flows like checkout.started → payment.completed. If step 2 never fires within your window, NotiLens alerts you before the revenue disappears silently — no code instrumentation required.

Deploy & CI/CD monitoring

Catch broken deployments the moment the event sequence breaks. NotiLens watches for the expected deploy.completed after a pipeline run — and pages you if it never arrives.

AI agent monitoring

Send lifecycle events from your agent using the SDK (Python, Node.js, Go, and 4 others) or MCP server. Get alerted on loops, timeouts, token spikes, and human approval requests in real time.

Acknowledgement (ACK)

Critical alerts repeat every 5 minutes until someone acknowledges them. For Pro plan solo founders or pairs, nothing gets missed — even without a formal on-call rotation.

5-minute webhook setup

Create a topic, paste the webhook URL into Stripe, Shopify, or GitHub, and you're monitoring in minutes. No agents to install, no YAML to write, no infrastructure to manage.

What NotiLens sends your founding team

The exact alerts that help a 2-person team move with the confidence of a 30-person engineering org.

Critical

Startups lose customers to silent failures — not dramatic crashes.

Your signup form doesn't explode. It just stops working. Your Stripe webhook doesn't throw an error. It just stops delivering. NotiLens catches the silence that costs you the most — and alerts you before a user has to.

FAQ

Is NotiLens affordable for an early-stage startup? +

Pro plan is $29/month (or $24 annual). One caught payment failure or prevented outage pays for a full year. 7-day free trial, no credit card required.

Do I need a DevOps engineer to set up NotiLens? +

No. Most startup integrations are webhook-based — paste a URL into Stripe, Shopify, or GitHub and you're monitoring in minutes. The SDK takes under 15 minutes to add to any app.

We're a team of 2 — is on-call scheduling relevant for us? +

On-call is on the Team plan. For solo founders or pairs on the Pro plan, ACK alerts repeat every 5 minutes until someone acknowledges — ensuring nothing gets missed even without a formal rotation.

Can NotiLens help us monitor AI agents we're building? +

Yes. Send lifecycle events from your agent code using the SDK (Python, Node.js, Go, and 4 others) or MCP server. Get alerted on loops, timeouts, token spikes, and human approval requests in real time.
