Launching PSI Lynx on Product Hunt today

Fantastic! Nowadays, with the help of AI, things tend to get easier and easier, and this tool is a prime example. There are any restrictions? Good luck on the long road ahead...

nice concept!! good luck with the launch..

Excellent well done! I launch on Product Hunt tomorrow myself! How massively important to find out about regression, its' timing, and jump on things stat. Will have to check you all out. Appreciate your service:)

Ran a managed services business for almost twenty years, and the thing nobody buying monitoring will admit is that they don't want more dashboards, they want to never get the 7am "why is the site slow" email again. You already wrote that exact line in your post, so I'd lead with it. "Performance monitoring at scale" is a category. "Know which release broke it before your client does" is a sale. The trap with this kind of tool is alert fatigue. If the regression alerts aren't tied tightly to a specific deploy or script change, teams mute them within a month and you churn. The attribution is the moat, not the monitoring. Congrats on the second launch.

Good luck with the PH launch!

Congrats on the launch!

I think you've identified a real gap in the market. Most performance tools are great at showing the current state, but when performance slowly degrades over weeks or months, finding the actual cause becomes a detective exercise across deployments, third-party scripts, tag managers, and marketing tools.

One of the biggest challenges I've seen is attribution. Teams can see that Core Web Vitals or Lighthouse scores have dropped, but they can't easily answer, "What changed?" Was it a release, a new analytics script, a chat widget, an A/B testing tool, or a CMS update?

The historical tracking aspect of PSI Lynx sounds particularly valuable because performance regressions are often gradual rather than catastrophic. Looking forward to seeing how the product evolves. Good luck with the Product Hunt launch!

The "when did it start going wrong" angle is the right one — point-in-time scores hide the slow regressions that actually kill you. Love that framing.

On your closing question, from a narrow but maybe useful angle: I run a tool that proxies/renders Notion pages behind a password gate, so my performance is hostage to a third party (Notion) I don't control. My biggest challenge isn't measuring my own code — it's that an upstream change on Notion's side can tank my render times overnight, and I find out from users, not from a dashboard. Monitoring tools tell me my page got slower but not that the cause is external.

Genuinely curious: does PSI Lynx help separate "our regression" from "an upstream dependency regressed"? For anyone building on top of another platform that distinction is the whole game — otherwise you waste a day debugging your own code when the problem was never yours.

Good luck with the launch.

the bulk monitoring for large websites is where the product either works or doesn't for agency use cases. agencies managing hundreds of client sites need monitoring that scales without requiring manual configuration per site and without generating alert fatigue. what does the alert logic look like when you're monitoring thousands of URLs and a regression hits 40 of them simultaneously, like after a CDN config change, and how do you surface that as one incident rather than 40 separate notifications

Hey Paul,

Congrats on the launch! 🚀

This is exactly the kind of tool many of us have been needing. Most performance tools only give you a snapshot, but the real pain is figuring out when things started breaking and what caused it — especially after multiple deployments and third-party scripts pile up.

I’ve personally lost count of how many times we’ve seen Core Web Vitals slowly degrade over weeks and spent days trying to find the culprit. The historical tracking + regression alerts sounds super valuable.

Biggest challenge for me right now: Monitoring performance at scale across hundreds/thousands of pages without it becoming too noisy or expensive.

Will definitely check out PSI Lynx. Wish you the best with the Product Hunt launch today!

Congrats on the launch! Upvoted and Good luck! I am planning to launch mine this week. Do you plan to support GEO? it looks GEO is getting more and more important.

The gap you're filling is between 'what's wrong now' and 'when did it start going wrong.' Most performance issues are invisible until they've compounded over weeks. I've run into this with Genie 007. A third-party script degraded load time slowly and nobody caught it until organic traffic started dipping. Correlating deploy timestamps with score changes is the piece most teams don't have.

The timing angle is what makes this stand out — most performance tools hand you a snapshot of the current state, but that's not actually the hard problem for teams managing complex websites. The hard problem is: "we had a dozen deployments and four new marketing scripts added over the past two weeks, and now rankings are slipping — which one caused it?" Historical regression tracking tied to change events is exactly the right level of abstraction. The CrUX history addition is a smart move too, since synthetic lab scores can look clean while real users are still suffering. Congrats on the second PH launch, Paul!

The "tools show what's wrong now, almost none tell you when it started going wrong" framing is the sharp part, regression-over-time is a genuinely different product from a point-in-time audit, and way harder to fake. Congrats on the second launch. The "which release caused the regression" alerting is the bit I'd have killed for in past projects.

Congrats on the PH launch!

Congrats on the launch, Paul! Upvoted and wishing you the best of luck today.

The historical tracking angle is what stands out to me. Finding an issue is one thing, but knowing exactly when a regression started is usually the harder problem.

Good luck and upvoted on PH.

Took a quick look on the website and there is an issue on Sign in up on small screen devices when you cannot scroll to see the SSO options.

I'm not anti-SEO plugins. They clearly help a lot of people.

But in my case, I had zero budget. So I had no choice but to do everything manually. No Yoast. No Rank Math. No paid tools.

And honestly? It was harder. More work. More guesswork.

But I kept going anyway.

And — Alhamdulillah (thank God) — my site (thefrugalglow .com) is already getting organic traffic and showing up in Google Search Console. Manually indexed. Manually optimized. No shortcuts.

I'm not saying plugins are bad. I'm saying: if you literally can't afford them, don't let that stop you. It's possible.

Took me more effort. But the first step on the ladder is mine.

Anyone else here building with zero budget? Let's share stories.

Congrats on the PH launch! The "when did it start going wrong" angle is sharp — most tools only show the current state.

I'm Minchul, 57, former construction manager from Korea. Built Slash it — an Email Decision OS. Also preparing for PH soon.

Rooting for you today. 🚀

Launching on PH today too — good luck!

The first few hours are everything.

This sounds very interesting. Congrats and hope the launch goes well.

This is a strong direction, Paul.

I’d just be careful with the feedback you collect from this launch. “Website performance monitoring” can pull in very different people: SEO agencies, ecommerce teams, developers, founders, and each one will describe the pain differently.

The risk is not lack of feedback. The risk is treating all feedback as equal and letting the positioning get wider right after launch.

I wouldn’t try to solve that loosely in the thread because the useful decision is which buyer signal should matter most after Product Hunt.

If you’re open to it, share your email and I’ll put the tighter launch-signal read together properly.
