spdlog
by gabimeFast C++ logging library.
In simple words: fluentd is a tool made for people who build software, for recording everything a system does, for later checking. It is completely free and open source — its code is public on GitHub, where 13,611 people have bookmarked it as worth using.
💡 A real-life example: Behind every big app, tools like this quietly keep servers running, publish updates, and warn the team the moment something breaks.
RepoEasy wrote this simple explanation from the project's public data — its category, topics and description — so a beginner can understand it before downloading anything. For exact technical details, the project's own README (linked below) is the final word.

This project is listed under Logging in Infrastructure & DevOps, a category made for developers, sysadmins and self-hosters.
Do I need coding knowledge? Coding Knowledge Recommended. (Estimate based on project type: A developer tool/library — setup usually follows the README with basic coding skills. Always confirm from the repo's README.)
The source code is released under the Apache-2.0 license. Open-source licenses like this usually allow free use, including commercial use — but always read the actual license file in the repository before relying on it. Note: the code being free does not mean hosted services, APIs or infrastructure around it are free.
