Tembo integrates with observability tools like Sentry, Datadog, and New Relic to detect performance regressions, query slowdowns, and recurring exceptions. When it finds issues, it analyzes recent commits, traces the root cause, and opens pull requests with fixes or optimizations — often before anyone notices the problem.

glance
Glances an Eye on your system. A top/htop alternative for GNU/Linux, BSD, Mac OS and Windows operating systems.
Glances is nice. I think it is a clone of HP-UX Glance.

changedetection.io
Best and simplest tool for website change detection, web page monitoring, and website change alerts. Perfect for tracking content changes, price drops, restock alerts, and website defacement monitoring—all for free or enjoy our SaaS plan!
Project mention: rostral.io VS changedetection.io - a user suggested alternative | libhunt.com/r/rostral.io | 2025-08-05Rostral.io is an open-source tool for document monitoring with a focus on semantic analysis. Unlike traditional change detectors that track text differences, it processes PDFs, HTML, and JSON using local LLMs (like Deepseek) to identify meaningful modifications in legal texts, contracts, or regulations. The system uses YAML templates to define monitoring rules and can integrate with analysis tools. Designed for researchers and analysts who need to track substantive changes rather than just surface-level edits. Self-hosted for data-sensitive workflows.

Project mention: Fighting bots by implementing fast TCP fingerprinting with eBPF | news.ycombinator.com | 2025-06-29
something like https://github.com/renanqts/xdpdropper or cilium's host firewall or https://github.com/boylegu/TyrShield exist or https://github.com/ebpf-security/xdp-firewall today and implement ebpf filter based firewalling.
Of these there is a sample integration for XDPDropper to fail2ban that never got merged https://github.com/fail2ban/fail2ban/pull/3555/files -- I don't think anyone else has really worked on that junction of functionality yet.
There's also wazuh which seems to package ebpf tooling up with a ton of detection and management components, but its not a simple to deploy as fail2ban.

Healthchecks
Open-source cron job and background task monitoring service, written in Python & Django
I just got back from the iPC/iJS conference in Munich and had a great time. I brought back 7 lessons I learned (more on that later) and inspiration for other things. One of them was to get a handle of managing all of our cronjobs. We have 2 servers and several Elastic Beanstalk applications, all of which have their own cronjob setups. I've been having them email a group email address and tucking them away and reviewing them every once in a while to see if there were any errors. This led me to the thought that there's got to be a better way. I started thinking about how I could append a ping to a centralized service after each cron job and that service could monitor the jobs and then ping me if anything goes missing. Then I thought, wait a second ... maybe someone else has already done this. I DDG'd (DuckDuckGo'd) it and came across this writeup with several solutions. I checked out Healthchecks.io and upon digging deeper, saw that their software was available via a Docker image that you could self-host.

Project mention: Show HN: Claude Code Usage Monitor – real-time tracker to dodge usage cut-offs | news.ycombinator.com | 2025-06-19
If the repo was structured as a package e.g. with project.toml and such there would be an even faster one-liner with pipx (https://pipx.pypa.io/latest/):
> pipx install git+https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor
> ccusage_monitor
I think there is a similar command for uv; uvx?
