TencentCloud/Octop
Octop is a self-hosted AI assistant platform from TencentCloud aimed at households, families and small teams rather than individual chat sessions. A single `octop run` process serves a web dashboard, a command-line interface, instant-messaging integrations (Feishu, DingTalk, QQ, Discord, WeCom and others) and programmatic access over HTTP, SSE or WebSocket, all sharing one local control-plane database stored under `~/.octop/` (SQLite by default, with PostgreSQL as an option). Its multi-agent architecture lets one admin set up a shared environment where multiple users each interact with an expert library of specialist personas, including sixteen MBTI-based personality templates and an interactive quiz for assigning them, so different scenarios can be handled by differently 'voiced' agents. Security features include JWT-based multi-user isolation, a tool-approval step before agent actions run, shell-command guardrails and PII redaction, all enforced locally. It supports a connector ecosystem (a bundled Tencent suite plus OAuth and MCP gateways) for pulling in external services, pluggable storage backends (local disk, Docker, PostgreSQL or S3-compatible object storage), a portable memory system that migrates with the workspace, and a retrieval-augmented knowledge base over a user's own documents. An ACP integration lets it delegate tasks bidirectionally to IDE and terminal agents such as OpenCode or Claude Code with permission gates, and it includes a browser-automation mode using headless Chromium plus a remote-desktop feature giving live screen and input access on Linux, Windows or macOS. The project is written in Python and licensed as open source, positioning itself as a full self-hosted alternative to cloud assistant products that keeps all data on the user's own infrastructure.
