openclacky
The most Token-efficient open-source AI Agent
OpenClacky is an open-source AI agent designed for maximum token efficiency while maintaining performance comparable to Claude Code. Built on two years of agentic research, it achieves approximately 50% cost savings versus OpenClaw and 66% savings versus Hermes through a lean 16-tool architecture, near-100% cache hit rates, and intelligent context compression. The agent supports bring-your-own-key integration with any OpenAI-compatible model, features a self-evolving skill ecosystem invoked via natural language, and offers both terminal CLI and web UI interfaces. Developers can scaffold projects, add features, automate workflows, and create monetizable custom skills without writing code.

openclacky — FAQ
What is OpenClacky?+
OpenClacky is an MIT-licensed AI agent optimized for token efficiency, achieving comparable capability to Claude Code at approximately 80% of the baseline cost through intelligent caching, minimal tool architecture, and background context compression.
How do I install OpenClacky?+
Download the desktop installer (.dmg for macOS or .exe for Windows) from the official site, use the one-line curl/PowerShell install script, install via Ruby gem (gem install openclacky), or run the pre-built Docker image from GitHub Container Registry. All methods require Ruby 3.1.0 or later for gem-based installs.
Does OpenClacky require API keys?+
Yes, you must provide your own API key (BYOK) for any OpenAI-compatible model provider such as Anthropic Claude, OpenAI GPT, DeepSeek, Kimi, or custom endpoints. Configure keys via the /config command in the terminal or web UI.
Which AI clients work with OpenClacky?+
OpenClacky operates as a standalone agent with its own terminal CLI and web UI (port 7070 by default). It is not a plugin for Claude Desktop, Cursor, or other editors—it is a complete agent environment.
Is OpenClacky free to use?+
The OpenClacky agent software is 100% free and open-source under the MIT License. However, you pay for the underlying LLM API usage from your chosen provider (Claude, GPT, DeepSeek, etc.) based on your BYOK configuration.
How do I create and use skills in OpenClacky?+
Invoke existing skills with the / command for instant access to hundreds of pre-built workflows. Create new skills by describing what you want in natural language; the agent drafts the SKILL.md file, breaks down steps, validates execution, and self-improves after each run.
How do I install openclacky?+
Open the source repository on GitHub and follow its README. openclacky is a agent — MCP Agents Market links you directly to the official repo.
Is openclacky free?+
