Install 260 zero-dependency CLI tools with one command. Here's everything you need to know.
pip install evolver-tools
# or use the one-liner (no install needed):
curl -sL https://evolver-dev.github.io/evolver-tools/try.sh | bashPython 3.8+ is the only requirement. Every tool uses only Python standard library — zero external dependencies. Works on Linux, macOS, and Windows (including WSL).
The try.sh script downloads a standalone binary. No Python required. Great for CI/CD, Docker containers, or air-gapped environments.

# evolver-tools shortcuts
alias ev=evtool # Short alias
alias evl='evtool list' # List tools
alias evs='evtool search' # Search toolsevolver-tools ships with shell completion for bash, zsh, and fish:
# Install completion (one-time)

eval "$(_EVTOOL_COMPLETE=bash_source evtool)" # bash
# Add to ~/.zshrc for persistence:
echo 'eval "$(_EVTOOL_COMPLETE=zsh_source evtool)"' >> ~/.zshrcOnce enabled, press Tab after evtool to see all 260 tool names. Type evtool csv- then Tab to filter CSV tools only.
Analyze a CSV file end-to-end — stats, visualization, and export — without opening a spreadsheet.

Quick-check any JSON: curl -s https://api.example.com/data | evtool json-pretty | head -50
evtool dns-lookup site1.com > /tmp/a.txt && evtool dns-lookup site2.com > /tmp/b.txt && diff /tmp/a.txt /tmp/b.txt
evtool watch ./logs/ --patterns "error,warning" — watch for file changes matching patterns.
All tools work completely offline (except network tools like dns-lookup and weather-cli). Install once, use anywhere — including air-gapped servers.
For the best experience, use Windows Terminal with WSL (Ubuntu) and a Nerd Font. The ASCII art, progress bars, and TUI tools render best with proper Unicode and ANSI support.
