Stargazer is a fast and easy to use Gemini server with no runtime dependencies (if compiled with musl libc).

Project Status: The Stargazer project is currently in maintenance mode. I don't expect to add new features any time soon, unless someone else contributes them. My interest in the project has waned over time, and Stargazer is more or less feature complete. I will continue to push out new bug fixes and dependency bump updates as needed and when I have time. If you find any issues please do let me know.

Heavily inspired by gmnisrv.

#Install From Your Package Manager

Packaging status


docker pull zethra/stargazer Docker Hub

#Download Pre-built

You can download pre-built Linux binaries from the release page. The bundle contains a static binary, example config, and man pages. It should work on any distro.

#From crates.io

cargo install stargazer

#Build from Source


  • A POSIX or other compatible system
  • Rust compiler 1.77 or later and cargo
  • scdoc (optional) to generate man pages
  • strip (optional) (from binutils) to reduce the binary size
  • Python 3 (testing)
  • Python 3 cryptography (testing)
git clone https://git.sr.ht/~zethra/stargazer && cg stargazer
# As root
./scripts/install --prefix=/usr

If crates.io is inaccessible, Stargazer's dependencies for each release are also available on the release page. Simply download the vendor tar ball, extract it in the project root, and follow the instructions in the INSTRUSTIONS file.

#Minimum Supported Rust Version Policy

The required Rust version will not change between patch versions.

#Supported Platforms

Stargazer officially supports Linux and FreeBSD. It will likely work on other BSDs, macOS, Windows, and other platforms that its dependencies support, but it's not currently tested on those platforms. Other free platforms may be officially supported in the future if there are sufficient requests for them. Patches to support other platforms likely will be accepted though.


Configure stargazer by editing its config file, normally found at /etc/stargazer.ini. See stargazer(1) for CLI options and stargazer.ini(5) for configuration instructions.


Stargazer should be reasonably secure. I used it myself, and I've tested it quite a bit. However, Stargazer has been almost exclusively written by one person and hasn't gone through any formal code review or audit so keep that in mind.

Do be mindful if you use CGI scripts. It can be easy to write them incorrectly such that they cause security problems. Especially if they are written in POSIX shell.

#Know security issues

#FIXED Potential DOS if close_notify alert is received during a handshake - pre 1.1.1

Stargazer's dependency rustls had a vulnerability that could potentially affect Stargazer. See RUSTSEC-2024-0336 for more details.

#FIXED Potential DOS from pathological client cert - pre 1.1.0

Stargazer's dependency webpki had a vulnerability that could potentially affect Stargazer. See RUSTSEC-2023-0052 for more details.

#FIXED Root escape - pre 0.4.0

Stargazer would serve files from anywhere on the file system if a path starting with // was requested.

#Help Wanted with Packaging

If you can package stargazer please do! I currently maintain an Arch and Alpine package but if you can package for any other distro please do and let me know.
