12 alternatives to Kokonut UI
AgentValley is a free, MIT-licensed macOS app that shows every running Claude Code session and sub-agent in the MacBook notch: what each is doing, which model it uses, and which ones are waiting for you.
Ultracite is an open-source, zero-configuration preset for Biome, Oxlint and ESLint. It lints and formats JavaScript and TypeScript code and checks each edit an AI coding agent makes against a strict, shared set of rules.
OpenCode is an MIT-licensed AI coding agent that runs in the terminal, as a desktop app or in an IDE, and works with 75+ model providers, local models and existing Copilot or ChatGPT subscriptions.
Skillbox keeps your AI coding agents' skills in one library, tracks their GitHub/GitLab sources, scans every version for prompt injection and secrets, and syncs only the skills you choose to Claude Code, Cursor, Codex and 11 more tools. Free; Trim and AI from £6.99/month.
SKI is a macOS app that runs Claude Code, Codex, Cursor, OpenCode, Antigravity and pi side by side and lets you steer them by voice, hearing spoken results and alerts when an agent needs you, with a git branch and worktree per chat.
Dessn turns a team's existing codebase into a collaborative design canvas where every frame is the real app running from its own code, so designers, PMs and engineers can review what is live, prototype with real components and hand off merge-ready changes, including from coding agents over MCP.
LottieFiles is the platform for creating, editing and shipping Lottie animations. Its new Lottie AI turns a text prompt into an editable, interactive vector animation you can export as Lottie, dotLottie, GIF or video.
Clayzo is an animation engine and CLI built for coding agents: Claude Code, Codex or Cursor write motion graphics as typed TypeScript documents, render frames to check their own work, then export video or play the animation live on the web or natively in Swift.
FastAPI, React 19 and Postgres with auth, CRUD and 200+ end-to-end tests. Mocks and untested routes fail the build, so coding agents stay honest. Open source.
Wonder puts Claude Code and Codex agents, a git worktree per task, your running app and an editable design canvas in one desktop workspace. Agents run locally on your own subscriptions, edits made visually on the live app are applied back to code, and Wonder also serves external agents over MCP.
NitroStack is a platform for building, testing and hosting Model Context Protocol (MCP) servers. It combines an open-source TypeScript SDK, a desktop IDE called NitroStudio and a serverless host called NitroCloud.
Beacon is an MIT-licensed tool from Asymptote Labs that captures session history from Claude Code, Cursor, Codex, OpenCode and 20+ other agent harnesses, normalizes it into one trace format, and turns useful workflows and corrections into reusable knowledge for future agents.
