Build production-ready AI agents in both Python and Typescript.
BeeAI Framework is an open source framework for building production grade systems of multiple cooperating AI agents in Python or TypeScript. It is hosted by the Linux Foundation under open governance and focuses on reliability: rather than relying on prompting alone, it lets developers enforce deterministic rules on ag...
Effortlessly compose, extend, and observe every service in real-time for the first time ever.
iii is an engine for connecting functions, agents, APIs, models, browsers and machines into a single live system. The vendor describes it as the layer underneath agent frameworks and workflow engines, offering the convenience of a platform without lock in. Its design rests on three primitives: Function, Trigger and Wor...
The Continuous-Improvement Stack for Agents.
Judgeval is the listing for Judgment Labs, a company that sells what it calls a continuous improvement stack for AI agents. The platform is aimed at teams running agents in production who need to find out when those agents misbehave, understand why, and confirm that a fix works before shipping it. Judgment connects to...
Run many Claude Code (or Codex) sessions in parallel — across every project — from one screen.
Operator is a mission control app for running a fleet of coding agents from one screen. It keeps Claude Code and Codex sessions running on a server, so they continue after a laptop is closed, and each task runs in its own isolated git worktree. The interface centers on a kanban style task board where every card launch...
A visual playground for agentic workflows: Iterate over your agents 10x faster
PySpur is an AI agent builder and playground for engineers who need their agents to be reliable. It combines a drag and drop workflow editor with the option to define agents in Python code, and it adds testing so that failures can be found and fixed quickly rather than by reading raw terminal output. The workflow it p...
Event-sourced graph runtime for durable and stateful agents
activegraph is an open source Python runtime for long running AI agents from Yohei Nakajima, the creator of BabyAGI. It records everything an agent does in an append only event log and projects that log into a live graph of beliefs, tasks, evidence, decisions and dependencies. The graph becomes the agent's world: what ...
