OSINT-Tools-Library is a resource for open source intelligence investigators. It helps you find tools, references, and workflows in one place. It is built for people who need a simple list they can use during research, screening, due diligence, and online investigation work.
This project is maintained by the OSINT Newsletter and its community. It is useful if you want a central place to browse OSINT tools without searching across many sites.
Use this on a Windows PC with a modern browser.
A good setup includes:
- Windows 10 or Windows 11
- Chrome, Edge, or Firefox
- An internet connection
- Enough disk space for your browser cache and any files you save
- A PDF reader if you plan to keep notes or export lists
You do not need programming knowledge to use this resource.

If the page shows a rendered README, you can also use it right in your browser without downloading anything else.
After you open the repository, use the README as your main guide.
Common ways to use the library:
- Browse the list of tools by task

- Keep a local copy of the README for offline reference
- Share the repository with your team
If you extracted the ZIP file, look for files like:
- README.md
- notes
- links
- folders that group tools by category
Open README.md in a browser or text app to read it clearly.
This library can help you with common OSINT work such as:
- Finding people and usernames
- Checking domains and websites
- Looking up email clues
- Reviewing social media presence
- Mapping public records and web pages
- Organizing tools for repeat use
- Building a fast start point for new cases
It works as a reference list, so you can move from one task to the next with less searching.
A project like this usually includes sections such as:
- People search tools
- Username lookup tools
- Domain and DNS tools
- Email lookup tools
- Image and media tools
- Social media tools
- Archives and web history tools
- Metadata tools
- Mapping and location tools
- Browser extensions
- Safety and reporting tools
Each section may include links, short notes, and use cases. This makes it easier to pick the right tool for the job.
If you want to keep a local copy on your Windows machine:
- Download the ZIP file from the repository page
- Extract it to a folder
- Open the folder in File Explorer
- Double-click README.md if your system knows how to open it
- If not, right-click it and choose Open with
- Pick Notepad, Notepad++, or your browser
- Add the pages you use often to your browser bookmarks
If you prefer not to download files, you can keep the GitHub page open and use it as your working reference.
- Use the browser search box on the page to find a topic fast
- Keep a notebook for case links and notes
- Check tool pages before using them in a case
- Save only the tools you trust and use often
- Group your bookmarks by task
- Review the library often, since OSINT tools change
A clean workflow helps more than a long tool list.
When working with OSINT tools, keep your browser and system in good shape:
- Use an updated browser
- Keep Windows security features on
- Do not open files from unknown sources
- Use separate browser profiles for work and personal browsing
- Clear old tabs and cached files when needed
- Keep a record of the pages you visit
These habits help keep your research organized and reduce mistakes.
This library fits well in situations like:
- First-pass research on a person or company
- Quick link checks during a report
- Finding tools for a specific OSINT task
- Training new investigators
- Building a shared research reference
- Comparing several tools for the same job

The value of this library is simple: it saves time. Instead of searching from scratch, you can open one place and move through a set of tools that fit OSINT work. That helps when you want a steady process and a clear start point.
It is also useful for teams. One shared list can make case work more consistent and easier to repeat.
