KKCode vs Code Concert

KKCode is the mobile client for OpenCode — the AI coding agent that runs on your Mac. Connect to your local OpenCode server over Wi-Fi or Tailscale, and bring AI-powered coding assistance wherever you go. FEATURES • Multiple AI Models — Switch freely between DeepSeek, Zhipu, Qwen, Kimi, MiniMax, and any model supported by your OpenCode server. Model preferences are remembered per session and persist across conversations. • Streaming Responses — Responses stream in real time. Scroll freely while the AI is generating; KKCode keeps your position and never interrupts your reading experience. • Code & Markdown Rendering — Enjoy full syntax highlighting for code blocks, inline formatting, and rich markdown display. • Tool Call Transparency — See exactly which tools the AI invoked, review file changes, and inspect inputs and outputs for every tool call. • Image Attachment — Send screenshots or design mockups directly from your photo library. • Session Management — Organize conversations by project directory. Rename, swipe to delete, or bulk remove sessions whenever you need. • Split View Support — Keep your session list and active chat side by side for a desktop-class multitasking experience. • Offline-Safe Draft — Your unfinished messages are automatically saved per session and restored when you return. • Multi-language Support — English, 简体中文, 繁體中文, 日本語, 한국어, Deutsch, Français, Português, Русский. • Dark & Light Mode — Automatically follows your system appearance. HOW IT WORKS KKCode connects to the OpenCode server running on your Mac. Start the server with: opencode serve –hostname 0.0.0.0 –port 4096 Then add your server connection in KKCode and start chatting. For remote access outside your home network, Tailscale is recommended. KKCode requires an OpenCode server to function. It does not include built-in AI inference or AI models.

Code Concert lets a team gather around one AI coding agent. Connect to your own Code Concert server (open source) and use a Claude Code / OpenCode / Codex CLI session together, like a chat room. With this app you can • Receive tool-approval requests, questions from the AI and teammates' proposals as push notifications, and approve or answer on the spot • Attribution: the AI knows who said what and replies by name • Team chat: the AI listens to human conversation and only chimes in when a judge model thinks it should. In conductor mode only instructions approved by the admin are executed • Whiteboard: a board shared with agents on other machines and with teammates • Connect and log in by scanning the QR shown on your PC — no typing Requirements • A Code Concert server (Node.js 20+, one-line install from https://code-concert.com) • Claude Code, Codex or OpenCode, signed in with your own account or your organization's API key Pricing The app is free. Fees for Claude Code / Codex / OpenCode themselves are not included — you use your own accounts. Code Concert Cloud (share URLs, cloud whiteboards) is free during the preview; paid plans will be announced in advance. For rooms shared by a team we recommend API keys or conductor mode, where the admin approves every instruction; personal-plan logins are meant for the account holder.
