Greptile

Greptile connects to GitHub and local git checkouts, reads source files, and builds a searchable index of code, comments, and filenames. It pulls repo metadata, watches commits on branches, and updates the index when new commits arrive. You can restrict searches by language, path, file extension, or commit range, and it records the commit hash and file path for every match so you can jump straight to the exact version that contained the text.

It runs regex and token searches across large codebases and returns matches with surrounding context and hits-per-file counts. The plugin maps symbol definitions to their references by scanning import and include lines, so a single query can return both a function definition and the files that call it. It supports previews and opens the file at the right line in your browser or IDE when you want to inspect or edit.

Searches can be saved as named queries, scheduled to run on a branch, and shared with teammates via a short URL. Greptile also exports match lists as CSV or JSON and can filter results by author, date range, or commit message content. It records provenance so you can see when a match was added or removed and who pushed the change.

Use it during a migration or API change: run a single saved query to find every use of an old API across dozens of repos, open the exact lines in the right commit, and export the file list to assign fixes — no flipping between GitHub search, local clones, and spreadsheets. That saves time and reduces context switching when you need a reliable, repo-wide list of code locations to update.
