Hi everyone!<p>I’m Jose, the solo founder of AlertDown, an automated user flow monitoring tool for web apps. It notifies you when something breaks—before your users do.<p>Imagine end-to-end tests with real-time monitoring, catching regressions and silent failures without:<p>• Writing a single line of code
• Installing any dependencies<p>Just add your URL, and AlertDown will:
1. Extract all possible user actions (clicks, inputs, dropdowns, etc.)
2. Automatically test each flow, branching out dynamically
3. Detect silent issues like:<p>• Missing dropdowns
• Unresponsive buttons
• Third-party API failures<p>Unlike tools like Sentry or Datadog, these errors often don’t show up as obvious failures, which can lead to lost revenue.<p>Why I built this:<p>While working at a cash-constrained startup (not mine), we lost $1,347 in revenue due to a misconfigured feature flag at step 7 of our onboarding. We didn’t realize it until 3 days later—after a user reported it. :(<p>I’ve seen this issue repeatedly over the years:<p>• “Non-breaking” code silently causing regressions
• Third-party services failing unexpectedly
• Testing fatigue—running the same flows over and over manually<p>I thought an automated solution like this wasn’t possible, but after an initial POC and 5 months of work, it’s finally live and working!<p>Tech Stack:
• Remix, TypeScript, Vite
• Supabase
• Docker on Google Cloud Run & Compute Engine
Temporal.io for orchestration<p>What’s Next:<p>I’d love your feedback and ideas as I continue improving:
• Handling login screens
• Slack integrations for alerts
• Custom viewport testing<p>Try it out now (for free)!
I'm looking for some early adopters that would like to pilot the product.<p>You can access without paying (just head to the login page)—it’s currently in public testing!<p>Looking forward to your thoughts and feedback.<p>P.S:
And if you are part of a company or building your SaaS, I want to work close with you to craft a unique experience.
