Web console and HTTP API server for nanobot — an ultra-lightweight personal AI assistant framework

nanobot Web Console

English | 中文

A web console + API server for nanobot — an ultra-lightweight personal AI assistant framework.

nanobot provides a powerful agent core (tools, skills, memory, channels) but no HTTP API or web UI. This project adds both: a FastAPI server and a single-file web console.

Quick Start

Prerequisites: Python 3.11+, nanobot installed and configured (~/.nanobot/config.json)

Install via pip

pip install nanobot-ai         # install nanobot first
pip install nanobot-web-console
nanobot-console

Open http://localhost:18790.

Install from source

pip install nanobot-ai
git clone https://github.com/tankyhsu/nanobot-web-console.git
cd nanobot-web-console
pip install .
nanobot-console

CLI options

nanobot-console              # default: 0.0.0.0:18790
nanobot-console --port 8080  # custom port
nanobot-console --host 127.0.0.1  # bind to localhost only
nanobot-console --reload     # auto-reload for development
nanobot-console --version    # show version

You can also run as a Python module:

python -m nanobot_web_console --port 8080

Run as systemd service (Linux)

Features

Web Console

• Session History — Browse all sessions with channel filtering (Feishu / API / WS / CLI). Tool call and result messages render as collapsible cards.
• Live Chat — Real-time WebSocket chat with streaming thinking indicators, tool call events, and results. Content persists when navigating away.
• Settings — 6-tab configuration panel:
  • Agent — Model, temperature, max tokens, iterations, context window tokens
  • Channels — sendProgress / sendToolHints toggles
  • Providers — Edit API keys and base URLs per provider
  • Cron — Manage nanobot scheduled jobs (add / toggle / trigger / delete) and system crontab
  • Prompts — Edit SOUL.md, AGENTS.md, USER.md in-browser
  • Info — Tools, skills, memory viewer
• Knowledge Base (optional, pip install openviking to enable) — Browse viking:// filesystem, view file contents, upload/delete files, semantic search; shows install guide when not installed
• Dark / Light theme, mobile responsive, URL routing, IME-compatible input

API Server

• POST /api/chat — Simple chat with emotion detection
• POST /v1/chat/completions — OpenAI-compatible endpoint
• WS /ws/chat — Streaming chat (thinking / tool_call / tool_result / final events + 15s heartbeat)
• GET/DELETE /api/sessions/{name} — Session management
• GET/POST /api/config — View and update agent config
• GET/POST /api/cron/jobs — Nanobot cron job management
• /api/viking/* — Knowledge base (optional, requires pip install openviking)

WebSocket Protocol

Client sends:

{"message": "user text", "session": "ws:device-id", "constraint": "optional"}

Server pushes:

{"type": "thinking", "content": "..."}
{"type": "stream", "delta": "..."}
{"type": "stream_end", "resuming": false}
{"type": "tool_call", "content": "..."}
{"type": "heartbeat", "timestamp": 1739800015.0}
{"type": "final", "content": "...", "emotion": "happy", "session": "ws:device-id"}

Knowledge Base (Optional)

One command to enable:

pip install openviking

Restart nanobot-console — it auto-detects and initializes. When not installed, the server runs normally and shows an install guide in the Knowledge Base tab.

Knowledge Base Features

• File Browser — Navigate the viking:// virtual filesystem with directory support
• File Viewer — Built-in Markdown renderer to read knowledge base files in-browser
• File Upload — Drag-and-drop or click to upload multiple files; auto-indexed for semantic search
• File Delete — Confirmation dialog + error feedback
• Semantic Search — Full-text semantic search across all resources
• Live Chat KB Toggle — Button next to the input field to enable/disable RAG augmentation per message
