Open-source Gcore alternatives

NGINX, pronounced engine x, is a web server that also serves as a reverse proxy, load balancer, API gateway and content cache. The official open source repository is written in C and distributed under a simplified two-clause BSD license. Enterprise distributions, commercial support and training are sold separately by F5, Inc.

NGINX is installed software with binary packages for the major operating systems and Linux distributions, in stable and mainline versions, plus Windows executables and dynamic modules. Typical tasks covered by the project's introduction include installing SSL certificates and enabling TLS, load balancing, rate limiting and content caching. Topics on the repository list TCP, UDP and mail proxying, HTTP/2, HTTP/3 and QUIC. You can also build from source, and the full documentation includes a beginners guide, development guide and directive reference.

Technitium DNS Server is an open-source DNS server that can act as both an authoritative and a recursive resolver. People host it themselves for privacy and security, and it works out of the box with little or no configuration. A friendly web console is reachable from any modern browser.

It can block ads and malware at the DNS level for an entire network. By forwarding queries over DNS-over-TLS, DNS-over-HTTPS or DNS-over-QUIC, it limits what an internet provider can see or tamper with. A local DNS server also gives logs and statistics for understanding network activity, serves many queries from cache, and allows network-wide domain blocking. Repository topics also mention DHCP server functions and DNS-over-Tor.

The server is written in C# on .NET and runs on Windows, Linux, macOS and Raspberry Pi, with Docker support. It is released under the GPL-3.0 license, and the project site at technitium.com provides downloads and documentation. It is suited to home networks and organizations that want more control over name resolution.

This repository contains the sources for PowerDNS, a set of DNS server software. It includes the PowerDNS Authoritative Server, the PowerDNS Recursor and dnsdist, a DNS load balancer. All three can be built from the same repository, although they are also released separately as tarball, deb and rpm packages.

The authoritative server depends on Boost, OpenSSL and Lua and needs a compiler with C++17 support, and the project provides pdns-builder, a Docker-based build process for producing the different releases. Docker images are available, with the README mirrored to Docker Hub, and full documentation lives at doc.powerdns.com.

PowerDNS is copyright PowerDNS.COM BV and many contributors and is distributed under the GNU GPLv2, with the NOTICE file describing the exact license and exception. Bugs are reported on the GitHub issue tracker, and the changelog on the documentation site is the place to check for recent updates.
