get it — vs code extension

A VS Code OSINT extension for company research.

The Company Dossier extension brings competitive intelligence into your editor. Run it from the command palette or talk to the @dossier chat participant, and a complete, sourced company profile assembles right in the sidebar — website analysis, Wayback history, DNS recon and tech-stack detection included. Free and open source.

Install from the VS Code Marketplace View source
Public sources only — no login bypass, no private data, no surprises.

install from source

Clone, build, research

Open in VS Code, then drive it from the command palette or the chat participant.

what it does

Recon, without leaving your editor

This is more than a wrapper around a search box. The extension runs real reconnaissance against the public record and folds the results into a structured, multi-section dossier you can read inline:

  • Website analysis — reads the company's live site to understand what they do, who they sell to, and how they position themselves.
  • Wayback history — pulls archived snapshots so you can see how the business and its messaging changed over time.
  • DNS recon — inspects domains and records to map infrastructure and surface related properties.
  • Tech-stack detection — fingerprints the frameworks, platforms and tools the company builds and runs on.

All of it rolls up into the same nine-section company profile you get everywhere else — overview, people, hiring, money, locations, tech, news, relationships and risk — so a developer doing due diligence, a founder sizing up a competitor, or an engineer prepping for a partnership gets the full picture without ever leaving the workspace.

The chat participant

If you use VS Code's chat, you can summon the dossier conversationally. Type @dossier /research followed by a company name or domain and the participant gathers the signals, then streams back a sourced profile you can ask follow-up questions about. It's company research at the speed of thought — and it keeps your hands on the keyboard.

The command palette flow

Prefer menus? Open the command palette, run Company Dossier: Research a company…, type the target, and the structured dossier opens in the sidebar view. Same engine, same nine sections, same public-sources-only discipline as the web app and CLI.
