## What it is
Pelias is a modular, open-source geocoder built on Elasticsearch that converts addresses and place names into coordinates and vice versa. It is powered entirely by open data and supports fast autocomplete, multilingual results, and self-hosted deployment.

## Use cases
- geocode addresses to latitude/longitude in my app
- self-host an open-source geocoding service
- reverse geocode coordinates into place names
- add address autocomplete to a search box
- search for cities, venues, and countries by name
- import OpenStreetMap and open data into a geocoder

## When to choose
- you need a self-hosted, MIT-licensed geocoder with no per-query fees
- you want to control your own geocoding data including private datasets
- you need fast autocomplete for user-facing place search
- you want multilingual place name support

## When to avoid
- you only need occasional geocoding and prefer a hosted API without running Elasticsearch
- you cannot operate Elasticsearch and a data import pipeline
- you need routing or turn-by-turn directions rather than geocoding
