Open-source AI automation that unifies agents, flows and 770+ app integrations
Describe a task in everyday words and the agent determines the steps, chooses tools from your connected apps and MCP servers, and pauses for approval on sensitive actions.
Build automations on a canvas with branching, retries, waitpoints, subflows and error handling, then write inline TypeScript for the steps that need real code.
Every piece is MIT-licensed and community-built, covering the apps you already run, with an HTTP piece for any REST or GraphQL endpoint with auth and pagination handled.
Draft flows by chatting, store structured data in Tables that flows and agents can read and write, and keep internal documents searchable by every agent.

Zhipu AI's open platform for GLM large models, multimodal APIs, and agent building
Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
Build tool-using agents and expose or consume MCP services to connect models to external systems.
Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
Tune models on your data and prototype prompts interactively in the browser before shipping.

Provides industry-leading frontier intelligence and developer ecosystems, but lacks BigModel's specialized GLM architecture and native Chinese language optimizations.

Offers massive context windows and robust multimodal Gemini APIs, but differs in model architecture and regional enterprise tooling.
#3SpecialistAggregates hundreds of global models under one API endpoint, whereas BigModel provides direct native infrastructure for Zhipu's GLM models.

Massive prebuilt app ecosystem and polished UX, but significantly more expensive and proprietary.
Free / Open-sourcePowerful open-source workflow automation with robust self-hosting options, but steeper learning curve than Activepieces.

SpecialistOne API for 1,500+ production-ready generative media models
SpecialistStreamlined interface for deploying custom AI agents, but less flexible for traditional data integration pipelines.

Free / Open-sourceSpecializes in serverless open-source model hosting and dedicated GPU clusters, but provides less native proprietary GLM model integration.

Run, fine-tune, and deploy machine learning models with one line of code

SpecialistStronger focus on RAG knowledge bases and LLM application development, but less general business automation.
Delivers ultra-fast inference speeds for open-weight models, but focuses less on proprietary enterprise agent building toolkits than BigModel.
