About

Local Studio is a local-first macOS workstation made by Sybil Solutions. It helps people run, manage, and use self-hosted language-model backends without turning their work into a cloud account. The product brings controllers, models, providers, a browser, files, terminals, and coding agents into one Workbench.

The workstation supports local and remote controllers and common inference runtimes including vLLM, SGLang, llama.cpp, and MLX. Its OpenAI-compatible proxy gives applications one surface while model execution remains under the operator's control. The desktop source is public under Apache-2.0, and signed Apple Silicon builds are published through GitHub Releases.

Sybil Solutions also supports KittyLitter, a native iOS and Android companion for Codex, Claude, OpenCode, Pi, and Droid, and Codex Shim, a local Responses API bridge for bring-your-own-key models. These products share one goal: useful AI software should keep infrastructure choices, credentials, files, and sessions in the user's hands.
