[!TIP] UniRTM's powerful task runner empowers you to orchestrate deep security scans (like Trivy & Syft) perfectly alongside your environments.

What is it?

UniRTM (Universal Runtime Manager) prepares your development environment before each command runs. It keeps project tools, environment variables, and tasks in one .unirtm.toml file so new shells, checkouts, and CI jobs all start from the exact same setup.

Install and switch between dev tools like node, python, go, and more.
Load environment variables per project directory, including values from .env files and secure secret managers like SOPS.
Define and run tasks for building, testing, linting, and deploying projects.

While taking heavy inspiration from the brilliant tool mise (dev tools, env vars, and tasks in one CLI), UniRTM introduces several distinct architectural choices:

Pure Go Engine: Extreme parallel downloading capabilities leveraging goroutines.
Lightweight Native Shims: Replaces sluggish bash shims with a unified, high-performance Go router. This prevents $PATH explosion while maintaining near-native execution speeds.
Unifying Security via Tasks: While keeping the core engine minimal, UniRTM allows you to perfectly integrate external security scanners like Trivy or Syft into your reproducible task workflows.
Absolute Locking: Generates a unirtm.lock file that pins the exact checksums and versions of your downloaded tools for reproducible environments.

Supported Platforms

Fully supported on macOS (Apple Silicon / Intel), Linux (glibc & musl/Alpine), and Windows.

Demo

The following demo shows how to use UniRTM to install a specific version of go globally. Notice the speed and the built-in vulnerability scanning!

Quickstart

Install UniRTM

See Getting started for more options.

$ curl -sL https://raw.githubusercontent.com/snowdreamtech/UniRTM/main/install.sh | bash
$ ~/.local/bin/unirtm --version
UniRTM v0.1.0 macos-arm64 (2026-05-28)

Hook UniRTM into your shell (pick the right one for your shell):

# note this assumes unirtm is located at ~/.local/bin/unirtm
echo 'eval "$(~/.local/bin/unirtm env)"' >> ~/.bashrc
echo 'eval "$(~/.local/bin/unirtm env)"' >> ~/.zshrc
echo '~/.local/bin/unirtm env | source' >> ~/.config/fish/config.fish

Execute commands with specific tools

$ unirtm exec node@20 -- node -v
unirtm [email protected] ✓ installed
v20.x.x

Install tools

$ unirtm use --global node@22 [email protected]
$ node -v
v22.x.x
$ go version
go version go1.22.x macos/arm64

See dev tools for more examples.

Manage environment variables

# .unirtm.toml
[env]
SOME_VAR = "foo"

$ unirtm set SOME_VAR=bar
$ echo $SOME_VAR
bar

Note that UniRTM can also load .env files.

Run tasks

# .unirtm.toml
[tasks.build]
description = "build the project"
run = "echo building..."

$ unirtm run build
building...

See tasks for more information.

Example UniRTM project

Here is a combined example to give you an idea of how you can use UniRTM to manage your a project's tools, environment, and tasks with security baked in.

# .unirtm.toml
[tools]
terraform = "1"
aws-cli = "2"
node = "20"

[env]
TF_WORKSPACE = "development"
AWS_REGION = "us-west-2"
NODE_ENV = "production"

[tasks.plan]
description = "Run terraform plan with configured workspace"
run = """
terraform init
terraform workspace select $TF_WORKSPACE
terraform plan
"""

[tasks.validate]
description = "Validate AWS credentials and terraform config"
run = """
aws sts get-caller-identity
terraform validate
"""

[tasks.audit]
description = "Run deep security scans using Trivy and Gitleaks"
run = """
trivy fs --format cyclonedx --output sbom.json .
gitleaks detect --source . --no-banner
"""

[tasks.deploy]
description = "Deploy infrastructure after validation and audit"
depends = ["validate", "audit", "plan"]
run = "terraform apply -auto-approve"

Run it with:

unirtm install # install all required tools specified in .unirtm.toml
unirtm run deploy # automatically runs validation and audit dependencies first

Architecture & Environments Comparison

We believe in making deliberate architectural choices to support modern enterprise environments. Here is how UniRTM compares to ecosystem pioneers like mise and asdf across multiple dimensions:

1. Core Architecture & Execution

2. Environment & Context

3. Cross-Platform & Resilience

4. Ecosystem Affinity & Minimalism
