Connectonion

ConnectOnion is an open source Python framework and command line harness for building AI agents and connecting them to real services. A single co command per connection links an agent to Gmail, Outlook, Google Calendar and Meet, WhatsApp, Telegram, Discord, SMS, a real Chrome browser, Google Drive, YouTube and a Synology NAS, and plugs it into Claude Code and Codex as a skill source. It is aimed at developers who want to build and host agents without writing the surrounding plumbing. The Python SDK defines an agent from a prompt and a list of tools, and a single host call serves it with a frontend and backend already included. A library of ready tools covers bash, shell, file handling, browser automation, mail, calendar, memory and to do lists, and co copy pulls a tool's source into your project for customization. Dangerous operations trigger an approval step by default through a replaceable plugin. The toolkit also includes an agent identity with its own address and mailbox, a memory wiki, secret management, schedules, remote agent calls, interactive debugging with breakpoints, session logging, terminal UI components and co ai, a built in coding assistant that writes ConnectOnion agent code. The framework is free and open source under the Apache 2.0 license. New accounts receive $5 of model credit to try hosted models such as GPT, Claude and Gemini without their own API key. No paid plans are published in the documentation. The listing points to the documentation site, which is the main home of the project and includes a design journal explaining its architecture choices.
