Harpoon is a Python CLI tool that aggregates open source intelligence and threat intelligence lookups across many services (Censys, crt.sh, CIRCL passive DNS, BinaryEdge, etc.) through a plugin system. It is configured with API keys and used from the terminal to gather information on domains, IPs, ASNs, and certificates.

Use cases

• look up threat intelligence on an IP or domain from the command line
• query certificate transparency logs for a domain
• gather OSINT on an ASN
• check passive DNS records for a domain
• search cached versions of a webpage
• run reconnaissance during a security investigation

When to choose

• you want a single CLI wrapping many OSINT/threat intel APIs
• you do threat intelligence research or incident response from the terminal
• you want a plugin-based tool you can extend with your own sources

When to avoid

• you need a GUI or web dashboard for OSINT
• you want a fully automated pipeline rather than interactive CLI queries
• you cannot obtain API keys for the services you need
