zerostack

Why we included this project

zerostack is a terminal-based coding agent in Rust that keeps memory use low without dropping tools. It works with OpenAI, Anthropic, Gemini, and local Ollama models, exposes the standard coding-agent tool set, and can add more through MCP servers, so it fits into existing workflows instead of demanding a new one. Developers who have felt heavier JavaScript agents strain their machines will appreciate the roughly 16 MB footprint and sub-second startup, which make it reasonable to run several agents at once. The operational side is covered too, with permission modes and per-tool rules, runtime-switchable prompts for planning, review, or debugging, session save and resume with auto-compaction, git worktrees for branch-per-task work, and optional persistent Markdown memory. And if you work in an editor like Zed, the optional Agent Communication Protocol support lets it drive zerostack directly as the coding-agent backend.
