Typesense

Typesense is the typo-tolerant search engine: instant, relevant search-as-you-type with a simple API — the open-source Algolia alternative. 26.9k stars. License: GPL-3.0 (copyleft) — fine for typical SaaS use over the API, but understand the obligations before embedding or distributing it. It's the 'just works' choice for product search: faceting, geo-search, and vector search in newer versions, with managed Cloud available.

```bash

docker run -p 8108:8108 -v/tmp/data:/data typesense/typesense:27.1 --data-dir /data --api-key=xyz

```

```python

import typesense

client = typesense.Client({"api_key": "xyz", "nodes": [{"host": "localhost", "port": "8108", "protocol": "http"}]})

```
