The README describes a tool that started from the familiar local-development problem of freeing a busy port and later included container runtime support, dry-run mode, signal selection, shell completions, and cross-platform support. ### Adoption history The project is distributed through Cargo, Homebrew, release binaries, and a shell installer. The Homebrew input record also lists MacPorts, Nix, and openSUSE packaging. ### How it is used Developers use killport to free ports such as 3000 or 8080 during local development, optionally targeting native processes, containers, or auto-detected targets. ### Why package nerds care killport is a package-nerd example of a tiny workflow wrapper: it replaces repeated `lsof`, `netstat`, `kill`, and container-runtime commands with one installable CLI. ### Timeline - 2023: Repository created and v0.1.0 published. - 2023: v0.9.x releases followed through July and December. - 2024: v1.0.0 release published on 2024-05-20. - 2026: Repository activity continued through the v1.x line. ### Related projects - The README places killport near system tools such as process managers, port inspection commands, and container runtimes including Docker, OrbStack, Podman, Colima, and OCI-compatible runtimes. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** killport - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - killport: normalized package name match | nixpkgs package indexes: pkgs/by-name/ki/killport/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - zypper - killport - 2.0.0-1.2: normalized package name match | openSUSE Tumbleweed package metadata: killport from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | A tool to easily kill processes running on a specified port | https://github.com/jkfran/killport - MacPorts - killport: normalized package name match | MacPorts ports tree: sysutils/killport/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Cloud CLI packages](https://www.automicvault.com/pkg/cloud-clis/) - Belongs to a cloud or infrastructure command family. - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [gruyere](https://www.automicvault.com/pkg/brew/gruyere/) - Shares av.db curated category or tags: cli, ports, process-management, system. - [cpulimit](https://www.automicvault.com/pkg/brew/cpulimit/) - Shares av.db curated category or tags: cli, process-management, system. - [daemon](https://www.automicvault.com/pkg/brew/daemon/) - Shares av.db curated category or tags: cli, process-management, system. - [daemonize](https://www.automicvault.com/pkg/brew/daemonize/) - Shares av.db curated category or tags: cli, process-management, system. - [lockrun](https://www.automicvault.com/pkg/brew/lockrun/) - Shares av.db curated category or tags: cli, process-management, system. - [supervisor](https://www.automicvault.com/pkg/brew/supervisor/) - Shares av.db curated category or tags: cli, process-management, system. - [detach](https://www.automicvault.com/pkg/brew/detach/) - Shares av.db curated category or tags: cli, process-management, system. - [hapless](https://www.automicvault.com/pkg/brew/hapless/) - Shares av.db curated category or tags: cli, process-management, system. - [procs](https://www.automicvault.com/pkg/brew/procs/) - Local package facts share a topical domain.
