Features

Everything you need to
orchestrate AI coding.

Multi-Session Grid

Run 6+ Claude Code sessions simultaneously. Each gets its own terminal, status indicator, and quick controls. Expand any session for full interaction.

Magic Ring

Siri-style glowing orb for session health at a glance. Link sessions, share context, trigger debates between agents.

Telegram Bot

22 commands. Start sessions, approve permissions, upload files, run research — all from your phone. Bidirectional sync with web UI.

Activity Terminal

Live event stream from all sessions — tool calls, thinking, errors, costs — in one scrollable feed. Filter by session or type.

Debate Mode

Pit multiple Claude sessions against each other. Structured rounds, counterarguments, and a final verdict. Let AI argue so you don't have to.

Desktop App

Native app for Windows, macOS, and Linux. System tray, auto-updater, and offline-capable. Built with Tauri.

Permission Gate

Claude asks to run a command? Approve or deny from web UI or Telegram. Color-coded danger flags keep you in control.

Smart Sessions

Auto-compact (3 modes), cost budget caps, session rename, enhanced resume with search. Context meter shows remaining window.

Docker Ready

One docker compose up and you're running. Server, web UI, and Telegram bot — all in a single container.

Intelligence Layer

Your agents just got
a lot smarter.

Companion doesn't just manage sessions — it makes every agent more effective with automatic context enrichment.

WebIntel

Web Research & Docs
  • Auto-Inject Docs Detects 100+ libraries and auto-injects their documentation into agent context. No manual searching.
  • Web Research Search, batch-scrape, and synthesize — with source citations. One command: /research.
  • Site Crawl Engine Async crawling with configurable depth. Job management, polling, and 5-minute timeouts.
WebIntel Online CACHE STATS 94% hit rate 2.4 MB cached 847 hits AUTO-INJECTED drizzle-orm Schema, queries, migrations — 12 pages injected @hono/zod-validator Middleware setup, error handling — 4 pages grammy Bot API, keyboard, sessions — 8 pages injected

CodeGraph

Semantic Code Intelligence
  • Multi-Language Scanner TypeScript, Python, Rust, Go, Java. Extracts functions, classes, interfaces, components, endpoints.
  • Dependency Graph 906+ nodes, 745 edges. Imports, calls, extends, implements — all mapped with trust weights.
  • Impact Analysis Hot files, reverse dependencies, blast radius. Know what breaks before you change it.

FAQ

Frequently asked questions.

Do I need my own Claude subscription?

Yes. Companion uses your existing Claude Code subscription (Max or your own API key). We don't provide API access or charge for Claude usage — you pay Anthropic directly. Companion is purely the management layer on top.

What does Companion actually do?

Companion spawns and manages Claude Code CLI sessions on your machine. It gives you a web dashboard to run multiple sessions at once, automatic web research and code intelligence, a Telegram bot to chat with Claude from your phone, real-time activity monitoring, and shared context across sessions via the Magic Ring. Think of it as a command center for Claude Code.

How does the yearly subscription work?

Starter ($39/yr) and Pro ($79/yr) are billed annually. Your license key works for 1 year from purchase. When it expires, you drop back to the free tier (2 sessions, no WebIntel/CodeGraph). Renew anytime to re-activate. No auto-renewal surprises — you renew when you want.

What's included in the free tier?

Free tier gives you 2 concurrent sessions forever with the full web dashboard, Magic Ring, Telegram bot, templates, Debate mode, desktop app, and thinking mode. No account, no credit card, no time limit. Paid plans unlock more sessions and intelligence features (WebIntel, CodeGraph, Scheduled Sessions).

What's the difference between Starter and Pro?

Starter ($39/yr) bumps you to 6 concurrent sessions — great for everyday use. Pro ($79/yr) gives unlimited sessions plus the intelligence layer: WebIntel (auto docs + web research), CodeGraph (code dependency analysis), and Scheduled Sessions (calendar-based automation).

What are WebIntel and CodeGraph?

WebIntel automatically detects libraries in your code (100+ supported) and injects their documentation into Claude's context. It also provides web research and site crawling. CodeGraph scans your codebase to build a semantic dependency graph — functions, classes, imports, hot files, impact analysis. Both run locally and enrich every Claude session automatically.

Why does it run locally?

Companion runs locally on your machine via Docker or desktop app — it spawns Claude Code processes that need direct filesystem access. The app runs on localhost:3580. The only external call is license verification via pay.theio.vn. Your code and credentials never leave your machine.

How does the Telegram bot work?

Create a Telegram bot via BotFather, add the token to your .env. Available on all tiers (including free) with 22 commands: start sessions, send messages, approve permissions, upload files, and get real-time notifications. Stream Bridge lets you seamlessly switch between web and Telegram mid-conversation.

What are the system requirements?

Docker Desktop (recommended) or the native desktop app. Works on macOS, Linux, and Windows (WSL). Minimum 2GB RAM. You'll also need an active Claude Code subscription from Anthropic.

Is there a money-back guarantee?

Yes. All paid licenses come with a 30-day money-back guarantee. If Companion isn't right for you, email us and we'll refund your purchase — no questions asked.
