Curious about how things work. Building things on the internet. Currently:

[Cory Zilisch @TheZilisch]

@levelsio @cursor_ai @boltdotnew Builders shipping from scratch in 4 days — the one thing that kills the vibe after launch is finding out your game was down for 6 hours and you had no idea. Set up uptime monitoring before you submit. https://t.co/1ethgTK7D9 is free to start

[Cory Zilisch @TheZilisch]

@Tawheed The pendulum swings back. Anyone can vibe-code a feature now — the ones who win long-term are the ones whose product just *works*. Reliability and trust are what AI-wrapped SaaS actually has to earn. Building that into PingSentry from day one.

[Cory Zilisch @TheZilisch]

@mscode07 Building PingSentry — uptime monitoring for developers and small teams. Know when your site goes down before your users do. Free tier, no credit card needed. https://t.co/1ethgTK7D9

(Especially relevant today while X itself is having another outage 😅)

[Cory Zilisch @TheZilisch]

X is having another outage this morning (April 7 — add it to the 2026 list). The irony: I'm building PingSentry, an uptime monitor, on the platform that keeps going down. This is exactly why you monitor everything, including the tools you depend on. https://t.co/1ethgTK7D9

[Cory Zilisch @TheZilisch]

@marclou Agreed, but step 1.5: keep it up. So many indie products ship and quietly die — Render goes cold, server crashes, nobody notices. Found out one of my projects was down 3 days because a user DM'd me. That's why I built https://t.co/1ethgTK7D9

[Cory Zilisch @TheZilisch]

@IndieHackers One thing missing from most vibe coding stacks: uptime monitoring. You can ship in 30 min with AI but your Render instance goes cold at 3am and you won't know. I built @PingSentry for exactly this — free tier, instant alerts, 2 min setup.

[Cory Zilisch @TheZilisch]

@levelsio @cursor_ai @boltdotnew Pro tip for #vibejam entrants: 'accessible on web' the whole month means your hosting needs to stay up. Render/Vercel instances can go cold after a push. Set up a free uptime alert so you're not the last to know when yours goes down → https://t.co/1ethgTK7D9

[Cory Zilisch @TheZilisch]

Honest question for devs: when your site goes down at 2am, what's the FIRST thing you check?

Logs? Dashboard? Slack? Or do you just refresh the page and pray?

@TTrimoreau Building in public + networking for sure. Launched PingSentry a few days ago and the connections I've made here have been way more valuable than any marketing channel so far. The feedback loop is unreal.

[Cory Zilisch @TheZilisch]

Solo founder math:

Built PingSentry on Node.js + SQLite. One DigitalOcean droplet. Monitors every 30s.

Total infra cost: ~$12/mo.

Passing that efficiency to customers. Free tier = 10 monitors. Paid = $12/mo.

Launching Tuesday on Product Hunt.

@AleksejAros 100% — scratching your own itch is the best filter for what's actually worth building. GEO scanner sounds super interesting, what kind of insights are you surfacing? Always curious how AI handles local business data.

[Cory Zilisch @TheZilisch]

Wrote up the full story of building PingSentry — from idea to paying customers in a weekend.

The tech stack, real revenue numbers, and every mistake along the way.

@RONiNmedia000 Honestly haven't hit that ceiling yet — SQLite handles way more than people expect when you batch writes properly. For now it keeps the stack dead simple on a $6 droplet. I'll probably revisit around 10K+ monitored endpoints, but no rush to over-engineer early.

[Cory Zilisch @TheZilisch]

I just launched https://t.co/1ethgTK7D9 — a simple uptime monitoring tool I built from scratch.

It checks your sites every 30 seconds and alerts you via email, Slack, or Discord when something breaks.

Free tier, no credit card. Building this in public.

@lennysan The AI roles explosion makes sense — every company that shipped an AI feature in 2025 now needs people to figure out if it's actually working and what to build next. The "we added AI" phase is over; the "we need to make AI useful" phase just started.

[Cory Zilisch @TheZilisch]

@pauldix The bottleneck has definitely shifted from "writing code" to "knowing if code works in production." Teams shipping 10x more code but still running the same monitoring and testing setup from 2023 are going to have a rough year.

[Cory Zilisch @TheZilisch]

@levelsio The "reply to server errors with Ok fix this" workflow is wild. I've been doing something similar — piping error alerts into a chat where I can triage and dispatch fixes without opening my laptop. The gap between "notification" and "resolution" is collapsing fast.

[Cory Zilisch @TheZilisch]

@JesusBrDev Love the auto-revert loop — true dogfooding. For growth, building in public has been #1 for me by far.

[Cory Zilisch @TheZilisch]

@Ayoosh_Tech That's the best kind of motivation honestly — scratching your own itch. Looking forward to seeing what you ship next!

[Cory Zilisch @TheZilisch]

@benvspak Building https://t.co/1ethgTK7D9 — simple uptime monitoring. Just launched, free tier, no credit card needed. Solo founder keeping it lean with Node + SQLite on a $6 droplet. Shipping fast and learning even faster.

[Cory Zilisch @TheZilisch]

@RONiNmedia000 This kind of honesty is what makes build-in-public actually work. Most people only share the wins. Free product to email capture is smart — give value first, monetize later. Rooting for next week's launch.

[Cory Zilisch @TheZilisch]

@JesusBrDev Auto-reverting PRs when uptime drops is such a clever idea. PingSentry keeps it simpler for now — synthetic HTTP checks + fast alerts. But tying monitoring into CI/CD like that is really smart. How's adoption been?
