Linux

Ubuntu is an open-source Linux distribution developed by Canonical for desktop, server, cloud, and Internet of Things environments. It is distributed in desktop and server editions and is available for installation on physical and virtual machines.

FrontierAgent is an open-source agent runtime, terminal product, and evaluation suite for long-horizon research and file-based work. Its native terminal TUI provides a ReAct workflow in which one stateful agent researches, reads files, writes deliverables, runs commands, and iterates in a task-scoped sandbox, and an Agent Team workflow in which a coordinator maintains a task board, delegates bounded independent assignments to parallel sub-agents, collects structured reports, and synthesizes the result. Shell and file tools use a shared sandbox with read-only /inputs, working-state /workspace, and persistent /outputs directories. The TUI supports queued instructions during execution, approval-required diffs for mutating operations, local action traces, checkpointed sessions, resumption, and reversion. The same workflow engine powers a subprocess benchmark runner with deterministic artifact collection, concurrency, progress inspection, and reruns of individual failures. The repository also documents connection to the OpenAI-compatible Apodex-1.1 endpoint through the Apodex API.

AgentVerse OS is a personal cloud operating system for a developer and their AI agents, installed on an Ubuntu server and accessed through a browser from a laptop, tablet, or phone. It provides a windowed desktop, isolated project workspaces, browser-based VS Code and a terminal, and supports Claude Code and Codex agents whose work remains on the server. Each project runs in an isolated Incus container with Docker inside, its own network and access gate. A Rust core coordinates projects, workspaces, capabilities, applications, backups, and updates; Coder controls the workspaces, Komodo deploys application stacks, Caddy provides the entry points, and Tailscale supplies private access and certificates. Projects request capabilities such as S3 storage, an LLM gateway, or notifications, which the core connects to provider networks and exposes through environment variables. The system includes a store combining catalogs from Runtipi, Coolify, and Umbrel, with guided installation, logs, snapshots, rollback, and application updates. It also supports ZFS snapshots, restic backups, an embedded Svelte desktop PWA, and one-command installation from a release package or source. The project is in alpha, is designed for one person, has no user accounts or permissions yet, and requires a clean Ubuntu installation and a Tailscale account. The repository is licensed under Apache-2.0; store applications retain their own licenses.

useAgent is an open-source AI coworker that gives Claude Code, Codex, OpenCode, and Pi a shared workspace with isolated Linux computers, repositories, terminals, browsers, and team tools. It can handle research, websites, spreadsheets, reports, presentations, and code changes, returning usable files, artifacts, or pull requests through a web app, Slack, REST API, or scheduled tasks. Each run is stored as an event log in Postgres and uses a common event contract across supported agent engines. Daytona or CubeSandbox provides the isolated workstation, while integrations cross a trusted gateway as typed tools so credentials remain on the control plane rather than entering the sandbox. The workspace also supports versioned skills and playbooks, team knowledge and memory, approval-gated tools, revisioned workpieces, and durable sessions. The repository describes useAgent as alpha software with changing APIs and schemas. It can be self-hosted on Linux using Bun and Postgres with pgvector, and is licensed under AGPL-3.0-only; a commercial license is available for proprietary embedding, distribution, OEM, or white-label use.

LiveKit Agents is an open-source Python framework for building programmable, real-time multimodal voice agents that run as server-side participants. It combines speech-to-text, large language models, text-to-speech, and realtime APIs with LiveKit's WebRTC clients, telephony stack, RPC and data APIs, and MCP tool support. The framework provides agent sessions, server-side job scheduling and dispatch, semantic turn detection based on a transformer model, multi-agent handoffs, and tools for voice, text-only, transcription, vision, and video-avatar applications. Agents can be tested with native test integration, including event assertions and LLM-based judges, and can run locally in console mode, in development mode with hot reloading, or in production mode. The framework can use LiveKit Cloud or a self-hosted LiveKit server and is distributed as a Python package with plugins for model providers. The Agents framework is licensed under Apache-2.0; LiveKit turn-detection models use the LiveKit Model License.
