In terms of feature-completeness, where does this lie exactly? Is this ready for production or more like a pet project I can mess around with?

The server is production-ready: WebSocket handling, authentication, JSON pattern matching, and broadcasting through Redis/RabbitMQ are all stable.

The client is still in active development and is currently mostly used to help with testing

Typesense also maintains a native Rails integration (fork of Algolia's one). You can automatically index on write, conditionally index documents based on business logic and a bunch more.

As I'm not super versed in the Rails ecosystem, could you share some specifics on Meilisearch integration's features so we could take some inspiration on improving ours? Would love some feedback.
