tomba-tech

Detect the technology stack of any domain from your terminal — powered by the Tomba Technology Finder API.

A single-binary Go CLI that takes a domain and returns the detected technologies (CMS, framework, hosting, analytics, ESP, payment, CDN…) as a table, JSON, or CSV.

Zero SDK dependency. This tool calls the Tomba REST API directly with net/http — the main.go is a complete, working reference for how to integrate Tomba into your own Go code.

Features

• One-shot: tomba-tech stripe.com
• Batch via args or stdin
• Three output modes: table (default), --json, --csv
• One non-stdlib dep (olekukonko/tablewriter) — calls the API with plain net/http
• Single static binary — drop it in $PATH and go

The curl equivalent

This CLI is just a friendly wrapper around one HTTP call:

curl -G 'https://api.tomba.io/v1/technology' \
     --data-urlencode 'domain=stripe.com' \
     -H "X-Tomba-Key: $TOMBA_KEY" \
     -H "X-Tomba-Secret: $TOMBA_SECRET"

Pipe through jq for fields:

curl -sG 'https://api.tomba.io/v1/technology' \
     --data-urlencode 'domain=stripe.com' \
     -H "X-Tomba-Key: $TOMBA_KEY" \
     -H "X-Tomba-Secret: $TOMBA_SECRET" \
  | jq -r '.data[] | [.name, .categories[0].name] | @tsv'
