Features
Everything a solo founder needs.
No DevOps team. No configuration overhead. Just clear signal on what's failing and what it's costing you.
One dashboard for your entire stack
Connect your providers — hosting, databases, email, payments and mobile stores. Each one shows its operational status and key metrics: service count, deploy state, storage used, delivery rates, charge success rates and more. All auto-refreshing, with health history.
Revenue correlation
See exactly how each incident affects your revenue — per product, in real time. Connect Stripe, Mercado Pago or LemonSqueezy.
AI postmortem in one click
Full incident timeline, root cause, impact analysis and action items. Generated automatically, exported as PDF before the incident is even cold.
Health score per product
Organize APIs, websites and heartbeats into products that mirror your real projects. Each product gets its own health score so you can tell at a glance which part of your stack needs attention.
Slack alerts from day one
Alerts reach you where you work. Slack is included in the free plan — no upgrade needed to get notified when things break.
Synthetic monitoring (Playwright)
Describe a user flow in plain English — login, checkout, search — and AI generates a Playwright script that runs on a schedule. Real browser, real interactions, real confidence.
Dependency map
Paste your domains and see your entire infrastructure mapped out — which services depend on what, where the single points of failure are and what to monitor first. AI-powered, one click.
Use Cases
Built for the way you build.
Whether you ship a SaaS, an API product, a storefront or a mobile app — Probecast fits your stack.
For SaaS Founders
Your SaaS depends on Stripe, Vercel, Supabase and Resend. When any of them breaks, your customers feel it. Know the moment it happens.
Explore use case →API-FirstFor API-First Products
You integrate with OpenAI, Twilio, Stripe and a dozen other APIs. When one goes down, your product breaks. Know before your users do.
Explore use case →E-commerceFor E-commerce & Marketplaces
A payment gateway down for 30 minutes can cost you thousands. Monitor your checkout flow, payment providers and fulfillment APIs.
Explore use case →MobileFor Mobile App Builders
Backend, push notifications, payments and app store status — all in one dashboard. Know when something breaks before the 1-star reviews.
