No-code builder for custom AI agents and workflows
Assemble agents with a drag-and-drop interface, 100+ templates, and optional code extensions when you need more control.
Connect leading models and business services so agents can reason, retrieve data, and take action across your stack.
Ship agents as web apps, browser extensions, webhook endpoints, or scheduled automations for teams and customers.
Add review steps and validation so agents produce reliable output before and after going live.

Open-source AI gateway with observability and evals built in
Route to OpenAI, Anthropic, Google, xAI, DeepSeek, Qwen and many other models through a single API key and one OpenAI-compatible endpoint.
Keep your existing OpenAI, Anthropic, LangChain or Vercel AI SDK code and change only the base URL.
Automatic fallbacks, retries and load balancing across providers and API keys keep requests answering when a single provider rate-limits or fails.
Every call is logged and traceable, with evaluation tooling and a CLI so you can query logs and traces from your terminal.
