    Hey guys, I'm building erlog to try and solve problems with logging. While trying to add logs to my application, I couldn't find any lightweight log platform which was easy to set up without adding tons of dependencies to my code, or configuring 10,000 files. ErLog is just a simple go web server which batch inserts json logs into an sqlite3 server. Through tuning sqlite3 and batching inserts, I find I can get around 8k log insertions/sec which is fast enough for small projects. This is just an MVP, and I plan to add more features once I talk to users. If anyone has any problems with…

    Hey everyone! I’m working on Telescope - an open-source web-based log viewer designed to make working with logs stored in ClickHouse easier and more intuitive. I wasn’t happy with existing log viewers - most of them force a specific log format, are tied to ingestion pipelines, or are just a small part of a larger platform. Others didn’t display logs the way I wanted. So I decided to build my own lightweight, flexible log viewer - one that actually fits my needs.

    Hello everyone, there are many log services available and this is my attempt at a better one. Most online logging tools feature convoluted UIs, arbitrary mandatory fields, questionable AI/insights, complex pricing, etc. I hope my application fixes most of these issues. It also has some nice features, such as automatic Geo IP checks and public dashboards. Although I've created lots of software, this is my first open source application (MIT license), the tutorial for selfhosting is hopefully sufficient! Most of my development career has been with C#, NodeJS and PHP. For this project I've…
