Stop building custom backends to track IoT uptime. Qrystal Uplink is a cloud-based watchdog for ESP32 & embedded fleets. We use "fail-closed" logic: if your device goes silent (crash, power loss, freeze), we alert you instantly via Email (as well as Slack, Telegram, etc. in the future). Replace weeks of infrastructure work with 5 minutes of integration: • Officially maintained platform SDKs. • One line of code. • No servers to manage. Focus on your firmware. Let us handle the plumbing.
Hey hunters 👋
I'm Mikayel, building Qrystal Uplink solo from Armenia!
Super excited to share that the platform is now available in beta. I built this because I was tired of a specific paradox in hardware development: It takes 30 seconds to monitor a website, but weeks to monitor an IoT fleet.
There is simply no middle ground. You either self-host a massive stack of tools you don't need or you choose a raw cloud like AWS/GCP/Azure and configure everything from scratch, including wiring up all the infra, writing backends, and managing updates.
Every time I started a new project, I found myself building the same "plumbing" over and over: provisioning servers, configuring databases, and writing custom APIs just to accept a "ping."
Worse, most teams rely on their data stream as a heartbeat. If your data server crashes or a sensor fails silently, your control panel looks fine, but the devices are actually dead.
I built Qrystal Uplink to be the external "watchdog" that solves this.
It is not a data platform. We don't ingest your sensor values.
It is a reliability layer. We only care if your device is alive.
The integration is designed to be invisible. We support ESP32 natively (Arduino & ESP-IDF) and MicroPython. If you are using an ESP32, you can be live in less than 5 minutes. Hopefully before you finish your coffee!
We offer a generous 1-month free trial on the base tier for developers and makers. I'd love for you to try it out and let me know if it saves you the weeks of infrastructure headaches it saved me. Feel free to reach out to me directly as well by dropping an email to mikayel@uplink.qrystal.partners or reach out to me directly via LinkedIn https://www.linkedin.com/in/mikayelgrigoryan/. Registrations until Jan. 24th will get a 20% off for their next month.
Note: During the beta, we are capping accounts at 10 devices to ensure maximum stability for early users. If you need volume-based pricing immediately, just let us know.
Happy to answer any questions and suggestions!
I'm very much looking forward to building this in public, so we will be rolling out additional features based on demand and community adoption. I hope this will become a useful tool for people who are deep into embedded.
@mikayelgrigoryan Hi Mikayel, congrats on the launch. fantastic use case that would generally be overlooked.
Thank you for the kind words @zolani_matebese! Appreciate you hopping on this cool journey with me.
Thanks a lot for the support@arssirek! Means a lot to me :)
