The best open source alternative to Sentry is GlitchTip. If that doesn't suit you, our users have ranked more than 50 alternatives to Sentry and many of them is open source so hopefully you can find a suitable replacement. Other interesting open source alternatives to Sentry are HyperDX, Logstash, SigNoz and DeepFlow.
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
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.
Open source observability platform. SigNoz helps developers find issues in their deployed applications & solve them quickly.
Unify your cloud-native monitoring with zero-code eBPF, advanced profiling, and 10x storage efficiency.
Errsole is a free open-source logger for Node.js applications. It comes with a built-in log viewer to view, filter, and search your application logs.
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)

highlight.io is a monitoring tool for the next generation of developers (like you!). Unlike the age-old, outdated tools out there, we aim to build a cohesive, modern and fully-featured monitoring solution, something we wished WE had. And it's all open source.
Healthchecks.io is a service for monitoring cron jobs and similar periodic processes:
Errbit is a tool for collecting and managing errors from other applications. It is Airbrake (formerly known as Hoptoad) API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server.
