F-Sync compares relationship exports from two Twitter archive ZIP files and renders an interactive HTML matrix highlighting mutuals, one-way followers, and block lists.
You can launch an HTTP server that renders the comparison interface on demand. Provide the paths to the two exported ZIP files and optionally enable handle resolution against twitter.com:
go run ./cmd/server --zip-a /path/to/first.zip --zip-b /path/to/second.zip --port 8080The server listens on 127.0.0.1 by default; use --host to override the bind address. Add --resolve-handles to fetch missing handles over HTTPS before rendering the page.
Health information is available at http://<host>:<port>/healthz, and the rendered comparison is served at the root path.
