About goaccess
GoAccess is an open source, real time web log analyzer and interactive viewer written in C and released under the MIT license. It parses web server logs and renders the results either in a terminal on nix systems or through a browser, updating every panel and metric every 200 milliseconds in the terminal output and every second in the HTML output. The project has been developed for roughly thirteen years and lives in the nix command line ecosystem, with a cluster of topics around analytics, Apache, Caddy, dashboards, and command line tooling.

About BillionMail
BillionMail is an open source mail server, newsletter, and email marketing platform that runs entirely on infrastructure the operator controls. It is written in Go and released under the AGPL 3.0 license, and it lives in the self hosted email and marketing ecosystem alongside the mail transfer and delivery components it bundles, including Postfix, Dovecot, and Rspamd. The project ships as a complete stack rather than a single binary, combining a sending server, a campaign manager, and a webmail client so that one deployment covers transactional mail, promotional campaigns, and newsletters.
