A model-agnostic Ruby framework for building AI agents and automations
Use OpenAI, Claude or Gemini — or plug in your own provider — without locking your app to one model.
Reusable classes for single generation tasks such as code from description or a description from code.
Operations that supply inputs to or act on the output of generators, like writing a file or running a command.
Autonomous entities with triggers such as file changes or time intervals — for example an agent that runs tests and fixes failing code.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
Free / Open-sourcePowerful open-source workflow automation with visual node building, offering robust self-hosting options but requiring technical setup.

Give your AI agents secure, authenticated access to 1,700+ apps
Free / Open-sourceA minimal, extensible terminal coding agent you can reshape
SpecialistVisual builder tailored specifically for custom AI agents, but less versatile for standard non-AI data synchronization tasks.
SpecialistBuild GTM systems that turn data into revenue


High-trust frontier inference, encrypted end to end
SpecialistAI-powered workspace generating automated workflows from prompts, but less focused on deep multi-system data synchronization.
Advanced no-code AI agent platform for complex web scraping and workflows, but less suited for basic app-to-app integrations.
Baidu's one-stop platform for building, distributing and monetizing AI agents

Free / Open-sourceThe TypeScript framework for building, deploying, and observing AI agents
Fast Apply and agent-tuned inference for coding agents

Secure enterprise automation platform built for complex workflows, but lacks Zapier's vast library of consumer app integrations.
