Adaptive dev environment CLI. Run holla in any directory and get an interactive menu showing exactly what you can do — based on what tools are installed on your machine.
No config. No setup. It just looks at what you have and shows you what's possible.
Holla is Rust-first. Prefer Rust for new project-owned commands, probes, release tooling, parsers, and long-lived automation; use another language only when an external ecosystem makes it the natural fit, and keep that exception local.
Product brief, mission, and roadmap: see PRODUCT.md.
Completed implementation-plan evidence: see docs/plan-completion-audit.md.
When you run holla, it probes your system for installed tools (git, docker, brew, gradle, etc.) and builds a menu on the fly. Only the tools you actually have show up.

Select an action and watch it run with live output per task, side by side.
| Group | Actions |
|---|---|
| macOS | Upgrade brew, brew casks, mise, amp — all in parallel |
| Git | Pull / push / status across all repos in the current directory |
| Project tasks | Run package.json, Just, Make, Taskfile, and mise tasks |
| Cargo | Build, test, clippy, and confirmed clean |
| Git hygiene | Fetch/prune, garbage collect, and confirmed merged-branch deletion |
| Brew services | Start, stop, and restart detected services |
| Docker | Stop all containers, full clean (containers + images + volumes) |
| Gradle | Stop daemon, clean build directories |
| IntelliJ IDEA | Remove .idea dirs and .iml files |
Groups appear only when the relevant tool is detected. A machine without Docker won't see the Docker group.
brew tap tailrocks/holla
brew install holla@previewThe recommended way (used for servers in this environment) is via the published holla-apt repository.
See the full design and install instructions in docs/debian-apt-repo.md (includes the proper host holla-apt.tailrocks.com, matching the velnor-apt pattern used in ChainArgos, GPG setup, CI flow, and user install with signed-by).
Debian packages (.deb) for amd64 and arm64 are also attached to every GitHub Release and can be installed directly with dpkg -i as a fallback.
The Linux launcher, Git/Cargo/project providers, task runner, disk scanner, and FreeDesktop Trash path are verified on Debian. macOS-only actions and cleanup insights are hidden. Native apt/dnf, systemd-user, and broader XDG insights are sequenced in the Linux port design.
cargo install --git https://github.com/tailrocks/hollaDebian packages (.deb) for amd64 and arm64 are also attached to every GitHub Release and can be installed directly with dpkg -i.
hollaZero config remains the default. For scripts and tooling:
holla list --json
holla run git.status
holla doctorlist --json emits a versioned {"v":1,"actions":[...]} envelope. Headless
destructive or explicitly confirmed actions require --yes.
Put global actions in ~/.config/holla/actions.toml, or project actions in
.holla.toml:
[[action]]
id = "team.deploy-staging"
label = "deploy: staging"
description = "Deploy current branch to staging"
command = ["./scripts/deploy.sh", "staging"]
danger = "mutating"
keywords = ["deploy", "staging"]
confirm = trueCommands are argv arrays only; shell strings are rejected. Project actions are marked unreviewed until their exact file hash is trusted. Editing the file requires review again.
