Open-source frontend stack for building AI agents and copilots inside your own product
Ship a working copilot UI in minutes with drop-in components for React, Angular, Vue, iOS, and Android, or go fully headless for total control over rendering.
A general-purpose bi-directional link between your app and any agent backend, with integrations for the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, Mastra, and many more.
Agents return real UI — charts, forms, tables, and approval prompts rendered with your own design system on the same screen the user is already working in.
Let agents read and write application state, call your frontend functions, and pause for human approval before sensitive actions are executed.
A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.

#1Features advanced computer use and interactive artifacts, but operates primarily as a chat assistant rather than a dedicated autonomous agent platform.

Executes tasks using cloud virtual Linux machines, but focuses more on personal desktop automation than complex multi-app research.
#3Free / Open-sourceProvides open-source personal task automation, but lacks the polished cloud sandbox environment of Manus.


Automates multi-step workflows and asset creation, but with fewer built-in general browser navigation tools.
SpecialistConverts prompts into structured office deliverables, but acts primarily as a document generation workspace.

Free / Open-sourceUnites multiple models and custom agents in a self-hosted workspace, but lacks pre-built autonomous execution sandboxes.
SpecialistDeploys autonomous business agents for operational work, but targets enterprise workflows rather than general open-ended research.

SpecialistDeploys agent fleets to build business deliverables, but requires more manual setup for complex web research.

SpecialistIDE extension providing model-agnostic AI coding assistance rather than a frontend UI component library for web applications.

SpecialistFocuses on Python-based agent building and deployment rather than frontend React component integration for web applications.
