The objective was to <strong>provide all the speed, scale, and flexibility</strong> of Fluentd in a smaller, more efficient footprint. The result was Fluent Bit.</p> <p>While Fluent Bit did gain rapid adoption in embedded environments, its lightweight, efficient design also made it attractive to those working across the cloud. Features to support more inputs, filters, and outputs were added, and Fluent Bit quickly <strong>became the industry standard unified logging layer</strong> across all cloud and containerized environments.</p> <p><strong>Fluent Bit has been deployed over a billion times and is trusted by some of the world鈥檚 largest and most complex organizations.</strong></p> </div> </div> </div> </div> </section> </div> <script async src="https://www.googletagmanager.com/gtag/js?id=G-93T2VC0VBC"></script> <script> var doNotTrack = false; if (!doNotTrack) { window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'G-93T2VC0VBC', { 'anonymize_ip': false }); } </script> <footer class="section pb-0"> <div class="container pb-5 d-none"> <div class="row"> <div class="col-md-8 "> <div class="row"> <div class="col-md-4 col-lg-3 footer-link"> <h6>Overview</h6> <ul class="mt-3"> <li><a href="#">What we Do</a></li> <li><a href="#">Why Fluentd?</a></li> <li><a href="#">User testimonials</a></li> <li><a href="#">FAQs</a></li> </ul> </div> <div class="col-md-4 col-lg-3 footer-link"> <h6>Resources</h6> <ul class="mt-3"> <li><a href="https://docs.fluentbit.io/manual/">Documentation</a></li> <li><a href="#">Data sources</a></li> <li><a href="#">Data outputs</a></li> <li><a href="#">Plugins</a></li> </ul> </div> <div class="col-md-4 col-lg-3 footer-link"> <h6>Community</h6> <ul class="mt-3"> <li><a href="/blog/">Blog</a></li> <li><a href="#">News Letter</a></li> <li><a href="#">Feedback</a></li> <li><a href="#">Contributing</a></li> <li><a href="#">Community List</a></li> <li><a href="#">Related Projects</a></li> </ul> </div> <div class="col-md-4 col-lg-3 footer-link"> <h6>Download</h6> <a href="https://docs.fluentbit.io/manual/installation/getting-started-with-fluent-bit" class="btn btn-gradient">DOWNLOAD NOW</a> <p class="last-ver">Last Version v3.2.1 </p> <p class="ver mt-1">Released On <strong>Nov 16, 2024</strong></p> </div> </div> </div> <div class="col-md-4"> <div class="footer-right pl-0 pl-md-3"> <img src="/images/footer-logo.svg" alt="Fluentbit, High Performance"> <p class="mt-3 ">The only log forwarder & stream processor <br> <strong>that you ever need.</strong></p> <form class="mb-4"> <p class="mb-1">Stay Updated</p> <div class="input-group subscribe"> <input type="email" class="form-control" placeholder="Enter your email"> <span class="input-group-btn"> <button class="btn btn-theme" type="submit"><i class="fa fa-send"></i></button> </span> </div> </form> <ul class="socail-link"> <li><a href="https://launchpass.com/fluent-all"><i class="/images/slack-color.svg"></i></a></li> <li><a href="https://twitter.com/fluentbit"><i class="/images/twitter-color.svg"></i></a></li> </ul> </div> </div> </div> </div> <div class="container foot-top"> <div class="row"> <div class="col-md-5 col-lg-3 col-sm-4"> <div class="footer-right new-footer pl-0 pl-md-3 align-items-center f-bod-right"> <div class="text-center text-md-left"> <p class="mb-2 d-inline mr-2"><strong>Stay Updated</strong></p> <ul class="socail-link d-inline"> <li> <a href="https://launchpass.com/fluent-all" target="_blank" aria-label="social link"> <img src="/images/slack-color.svg" alt=""> </a> </li> <li> <a href="https://twitter.com/fluentbit" target="_blank" aria-label="social link"> <img src="/images/twitter-color.svg" alt=""> </a> </li> </ul> </div> </div> </div> <div class="col-md-7 col-lg-6 col-sm-4 footer-link d-none d-md-flex align-items-center justify-content-center f-bod mt-3 mt-sm-0"> <div class="ml-3"> <p class="last-ver text-right">Last Version v3.2.1 </p> <p class="ver mt-1 mb-0">Released On <strong>Nov 16, 2024</strong></p> </div> <a href="https://docs.fluentbit.io/manual/installation/getting-started-with-fluent-bit" target="_blank" class="btn btn-gradient">DOWNLOAD NOW</a> </div> <div class="col-md-3 col-lg-3 col-sm-4 d-none d-md-block fot-logo"> <div class="footer-right new-footer pl-0 pl-md-3 align-items-center"> <div class="text-center text-md-left "> <img src="/images/footer-logo.svg" alt="Fluentbit, High Performance"> </div> </div> </div> </div> </div> <div class="copyright"> <div class="container"> <div class="row"> <div class="col-md-12 col-lg-12 copy-info text-gradient"> 漏 2015-2024 The Fluent Bit Authors.
