Minimize your downtime by being the first to know about it! Start off with 15 Uptime Monitors, checked every 1 minute, from around the world, completely FREE forever.
The simple, yet effective way of monitoring all of your IPs & Domains and notice if any of them get blacklisted on the most popular blacklists, so you can immediately take action to find the cause and start the delisting procedures, before it gets to affect your clients or your network reputation.
Tempreon is a personal memory layer for your AI tools, connected over MCP. Your knowledge, preferences, and decisions travel across Claude, ChatGPT, Cursor, and any MCP-capable client — captured once, available everywhere. It learns how you actually work instead of just storing what you said.
HetrixTools
TempreonHetrixTools is recommended for small to medium-sized businesses, system administrators, website owners, and anyone looking to monitor uptime and performance of their web resources without breaking the bank. It's particularly beneficial for those who need IP blacklist monitoring or have multiple servers or websites to manage.
Tempreon's answer:
Tempreon started with a simple observation: AI models keep changing, but the thing that makes them useful to you — your context, your preferences, your judgment — gets rebuilt from scratch inside every tool, and lost every time you move.
We built the layer that fixes that: person-owned memory served over the open Model Context Protocol, so it works across assistants instead of belonging to one. Along the way we open-sourced the pieces that are useful to everyone regardless of whether they use Tempreon — like memhaul, our MIT-licensed CLI for turning ChatGPT and Claude data exports into files you own.
The through-line is custody: the model is temporary, your memory shouldn't be.
Tempreon's answer:
Most alternatives in this space are memory infrastructure for developers building their own AI apps. If you're the person using several AI tools every day, that's not your problem — your problem is re-explaining yourself to each of them and losing everything when you switch.
The choice is really about who the memory is for. Ours is for you.
Tempreon's answer:
Tempreon is built for the person, not the app. Most memory products are developer APIs for adding memory to a single product; Tempreon is a memory layer you own that travels with you across every AI tool you use — Claude, ChatGPT, Cursor, anything MCP-capable.
Tempreon's answer:
Individuals who live in AI tools all day: operators, consultants, founders, sales professionals, and knowledge workers who use more than one assistant and are tired of being a stranger to each of them.
If you've ever pasted the same context into Claude and ChatGPT in the same week — you're the audience.
Tempreon's answer:
The protocol choice is the product decision: build on the open standard, and your memory works everywhere the standard does.

Https://hetrixtools.com/ It's free if you don't have too many servers - 15 uptime monitors (the most useful) and 32 blacklist monitors (useful for e-mail, but don't know why you'd need so many compared to uptime). It's fairly easy to reach the free limits with not many servers if you're also monitoring VMs, but I've found it reliable so far. It's nice you can have ping tests from different locations. - Source: Hacker News / about 2 years ago
You can use "htop" command to view current CPU, RAM and SWAP usage, also see which process is taking up how much of each resource. And if you want to collect data over time, you can use a monitoring agent like https://hetrixtools.com/ to monitor network, cpu, ram, disk access etc all of the time. Source: over 3 years ago

I'm using Ziply and they have been pretty much rock solid. I have a free uptime service via https://hetrixtools.com/ and they claim that in 2022 my uptime percentage is 99.9990%. And likely some of that is when I have decided to reboot my router. Source: about 4 years ago
