AstroGrep

What AstroGrep is

AstroGrep is a free Windows utility for finding words, strings, and regular expressions in text-based files. It searches local, removable, and network locations, including directories and projects, and shows surrounding text for each match so readers can assess context in code or documents. Searches can be narrowed by file type, date, or size. Results can be printed or exported for documentation, reporting, or auditing. AstroGrep can run from a folder or USB drive without installation, and the maker provides command-line examples for searching project files. It is not intended for binary or encrypted file formats. Its application privacy policy says it operates locally and does not collect, transmit, or store user data; the website may collect basic browser and system information, anonymous analytics, and information sent through contact forms or email. AstroGrep is free to download, use, and distribute. The maker describes it for developers, system administrators, testers, IT professionals, researchers, and people working with code, logs, documentation, or text files. Bug reports and feature requests can be sent through GitHub Issues or by email.
