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.

- ✓ Durable execution — resumes from a checkpoint instead of restarting after failure
- ✓ Native human-in-the-loop and short/long-term memory primitives
A free, open-source Swift library that brings LangGraph's stateful, multi-step AI agent pattern natively to iOS and macOS development, without needing a separate Python backend.
- ✓ Ports the LangGraph state+graph pattern natively to Swift
- ✓ Checkpoint-based persistence, pause/resume support
Python framework for role-based multi-agent teams: Crews plus event-driven Flows, from MIT open source to enterprise suite.
- ✓ Intuitive role-based Crew model — fastest multi-agent prototyping in Python
- ✓ MIT license, 55k+ stars, very large community
Lets you build automations by describing them in plain English instead of dragging boxes around a workflow canvas, then connects them to tools like Slack, Notion or Google Sheets.
- ✓ Construction d'automatisations par description en langage naturel, pas de canvas visuel
- ✓ Agents IA capables de raisonnement et d'autocorrection, pas seulement du if-then
Gives AI agents a real memory and a private workspace so they stop forgetting everything between conversations and re-reading the same documents over and over.
- ✓ Mémoire persistante avec extraction automatique de faits et résolution des contradictions
- ✓ Temps de réponse inférieur à 300ms selon l'éditeur
Lets a company build one AI agent that lives inside Slack, GitHub, Linear and other tools it already uses, instead of juggling separate AI features bolted onto each app.
- ✓ Un seul agent partout au lieu d'IA fragmentées par outil
- ✓ Routage multi-modèles avec failover en cas de panne fournisseur
A privacy-first LLM gateway that routes requests across 600+ models without logging prompts, verified via a Trusted Execution Environment.
- ✓ Cryptographically verifiable no-logging via TEE attestation, not just a policy claim
- ✓ OpenAI-compatible API — easy migration from existing integrations
Turns OpenAPI specs into safe, typed tools that AI agents can call, without manual wiring.
- ✓ Generates typed, ownable code instead of a runtime black box
- ✓ Automatic read/write/destructive risk classification
Open-source enterprise AI platform connecting company knowledge across 50+ apps with permission-aware search.
- ✓ Open source (Apache 2.0), self-hostable — no cloud lock-in
- ✓ 50+ pre-built connectors to enterprise apps
Free, open-source legal AI platform for document review, drafting and legal research.
- ✓ Free and open source (AGPL-3.0) — zero license cost vs. Harvey/Legora
- ✓ Grounded citations link answers back to source documents
A public message board built for AI agents rather than humans — any agent can post a note, request, or result by hitting a URL, with zero setup, no SDK, and no account.
- ✓ Poster ne demande qu'une requête GET, aucun setup
- ✓ Types de messages structurés + salons + flux Atom
An unofficial REST API that lets developers generate Midjourney images from code instead of Discord, with webhooks, polling, and SDKs — since Midjourney itself doesn't offer a public API.
- ✓ Accès API à Midjourney sans passer par Discord
- ✓ Webhooks et polling, SDK Python/Node.js
