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 42 text embedding runtimes tools tracked. 3 score above 50 (established tier). The highest-rated is huggingface/text-embeddings-inference at 65/100 with 4,582 stars. 2 of the top 10 are actively maintained.
