Opensquilla

OpenSquilla is an open source AI agent runtime built around a microkernel design and aimed at spending fewer tokens for the same work. It combines smart routing across models, persistent memory, a secure sandbox, built in search and local embeddings. The site lists more than ten built in chat channels, a library of meta skills for tasks such as paper writing, and a multi model fusion feature for combining answers from several models. The agent can be installed as a signed desktop app for macOS and Windows that bundles the control interface and the gateway runtime, through a terminal installer on any operating system including Linux, or from source for contributors. On first launch, onboarding walks through choosing a model provider and entering the requested keys, so the user supplies their own provider access. Recent releases added a beta Browser Use feature, model aware compaction for long sessions, plans and goals, and persistent task workspaces. The interface is offered in several languages, including English, Chinese, Japanese, French, German and Spanish. It suits developers and technical users who want to run a configurable personal or team agent on their own machine and control which models it calls. The software is released under the Apache License 2.0 and is free to download. The vendor does not publish paid plan prices, so any cost beyond the software itself comes from the model providers the user connects.
