OpenOSINT

OpenOSINT is an open source framework for open source intelligence work, aimed at security researchers and analysts. It places 21 investigation tools behind a natural language interface, so a user can type a target or a question and let an AI agent decide which tools to run, chain them based on findings and compile a structured report. It offers three interfaces. An interactive terminal REPL drives the AI agent, using the Anthropic tool use API with a user supplied Anthropic, OpenRouter or Ollama key. A direct command line runs individual lookups without AI, including email, username, IP geolocation and IP reputation checks, for scripting. An MCP server exposes all 21 tools to MCP compatible clients such as Claude Code and Claude Desktop. The site notes that every finding is shown with the tool call that produced it, and advises treating AI summaries as leads to verify rather than proof. A web demo and a prompt pack are also linked. The framework is free and MIT licensed for personal, commercial and closed source use, and installs with pip. A separate hosted option, OpenOSINT Cloud, is offered through the Apify platform from $0.02 per lookup, with email, username and domain reconnaissance tools. A broader Cloud tier with a hosted MCP endpoint and REST API is on a waitlist only, scoped to infrastructure intelligence rather than people search or breach lookups. Its planned plans of Free, Pro at $19 per month and Team at $79 per month are marked as not yet available for purchase. Organizations that need a signed contract, warranty or SLA can request one through a teams page.
