Text Embedding Runtimes Embedding Tools

Lightweight, language-agnostic libraries and inference servers for generating text embeddings locally. Includes runtime implementations across programming languages (Rust, Haskell, Elixir) and HTTP APIs for embedding inference. Does NOT include domain-specific embedding applications, vector databases, or embedding API providers.

There are 47 text embedding runtimes tools tracked. 3 score above 50 (established tier). The highest-rated is Anush008/fastembed-rs at 64/100 with 791 stars. 2 of the top 10 are actively maintained.
