GlitchTip's open source platform makes monitoring software easy. Track errors, monitor performance, check site uptime all in one place. Compatible with Sentry client SDK but easier to run and entirely open source.
Easy to deploy on k8s cluster, its awesome that glitchtip can use sentry sdk in apps. There are less features, but i hope it will develop further
Rollbar collects errors that happen in your application, notifies you, and analyzes them so you can debug and fix them. JavaScript, Ruby, Python, PHP, Node.js, Android, Flash, .NET, and Java libraries are available.
Honeybadger is an application health monitoring tool built by developers for developers. It's everything you need to keep production happy—and nothing you don't.
Logstash is an open source, server-side data processing pipeline that ingests data from a multitude of sources simultaneously, transforms it, and then sends it to your favorite "stash.".
Sentry is specifically designed as a software crash/error tracker, not as a general log gatherer. It collects things like internal variables at the time of the error/crash. Logstash is for collecting logs from software that functions normally.

Goxe is a high-performance log reduction tool written in Go, designed to reduce noise in observability pipelines. It ingests logs via Syslog/UDP, normalizes and filters them, and aggregates identical or repetitive messages into a single-line format with occurrence counts.
![This screenshot shows Goxe's terminal output. It displays a 'Partial Report' where repetitive log messages (like update versions and errors) are grouped with their occurrence count (e.g., [74961] repetitions). At the bottom, it highlights the tool's high efficiency, showing a memory footprint of less than 1MB while processing large volumes of data.](https://img.alternativeto.net/s/618x394/avif/goxe_881513_full.png)
