Mailwoman

An open-source (AGPL-3.0, dual-licensed) geocoder and postal-address parser. A ~29M-parameter neural model parses messy multilingual addresses; readonly SQLite artifacts built from open data (OpenStreetMap, Who's On First, Overture, national open address registers such as France's BAN) resolve them to coordinates — on a server, offline, or entirely in the browser via WebAssembly. Drop-in compatible with the Nominatim, Photon, and libpostal APIs. Every data artifact is reproducible and checksummed; every model release is gated by a published evaluation methodology.
