LocalAI has 49,179 GitHub stars, 4,458 forks, 201 open issues and last shipped today. pegainfer has 705 stars, 107 forks, 89 open issues and last shipped 2 days ago. LocalAI leads on adoption by 6,876% (49,179 vs 705 stars). LocalAI is written in Go under MIT; pegainfer is written in Rust under Apache-2.0. LocalAI has attracted 9% as many forks as stars, pegainfer 15%. LocalAI was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (llm), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About LocalAI
LocalAI is an open source AI runtime that enables running large language models (LLMs), vision, audio, image, and video models locally or on premises. It operates as a modular engine where each model type is backed by a dedicated, lightweight backend—such as llama.cpp, whisper.cpp, or stable diffusion—pulled only when needed. This composable architecture avoids bundling unnecessary dependencies, keeping the core minimal while supporting diverse modalities and hardware configurations.
