Maltego is the classic OSINT link-analysis tool, but at ~$999/year for Pro and a closed transform marketplace, many investigators prefer free, scriptable alternatives that integrate into existing recon pipelines. Whether you need breach-data lookups, internet-wide asset discovery, social-account enumeration, automated subdomain reconnaissance, or scriptable OSINT automation, the alternatives below match every modern recon workflow at a lower cost than Maltego Pro.
Free/OSS
Free service checking if email addresses or passwords have been exposed in data breaches.
vs Maltego: Free breach-data lookup service for emails, phone numbers, and passwords. Choose Have I Been Pwned for fast, free credential exposure checks rather than full link-analysis investigations.
Freemium
Internet-connected device search engine for discovering exposed services, IoT devices and vulnerabilities.
vs Maltego: Internet-wide scanner indexing exposed devices, services, and certificates. Choose Shodan if your investigation centers on internet-exposed infrastructure and IoT rather than people and accounts.

Free/OSS
OWASP attack surface mapping with advanced DNS enumeration.
