A code library from the LangChain team for building AI agents that can pause, remember where they were, and pick back up later — even after a server restart — instead of losing all progress if something goes wrong mid-task.

Best alternatives to Openheim in 2026
Building an AI agent that can actually do things — run shell commands, edit files, browse the web — usually means gluing together a specific LLM provider's SDK with your own tool-execution code, and redoing that work if you ever want to switch providers or add another interface. Openheim is a free, open-source runtime that does that gluing for you: write your agent logic once, and it works across OpenAI, Claude, Gemini, Ollama, or any OpenAI-compatible endpoint, with tool execution, conversation history, and multiple front-ends (a terminal UI, a headless CLI, or a direct plug-in to editors like Zed and Claude Code) already built in. Openheim is written in Rust and ships built-in tools for shell execution, file operations, directory listing, web fetching, and ripgrep-based search, alongside subagent delegation — spinning up isolated sub-agents with their own persona and even their own model choice for a subtask. It supports the Model Context Protocol (MCP) for surfacing external tools, configurable sandboxing to bound what an agent can touch on disk, and full conversation persistence with tool-call history across sessions. For editor integration specifically, it implements the Agent Client Protocol (ACP) over both stdio and WebSocket, which is what lets it plug directly into editors like Zed rather than requiring a custom integration per editor. It's MIT-licensed, ships a multi-stage Dockerfile, and has no commercial tier.
