# AI Agent Tools With a No-Code Builder

> Source: https://theagentsindex.com/collections/ai-agent-tools-with-a-no-code-builder (curated, quality-gated, re-verified)

No-code is a capability claim, not a sufficient description of every tool that accepts a prompt. This set requires each listing to document an actual build path. A visual canvas, connected flow nodes, drag-and-drop logic, or plain-English configuration can qualify when it lets a user configure an agent without writing the orchestration themselves.

The list includes several different shapes of no-code work. CrewAI and Microsoft AutoGen are code-first frameworks with optional visual studios. Replit Agent and Bolt.new turn a natural-language description into a working application. Retell AI, Bland AI, ElevenLabs Conversational AI, and Cartesia have visual builders inside products primarily aimed at developers or infrastructure-conscious enterprises. Their builders are real, even when the product's primary audience is not a hands-off no-code buyer.

The set also covers support, sales, workflow, voice, and data-agent products. Cresta, Sierra, Relevance AI, Dify, Glean, Botpress and Salesforce Agentforce document a visual or natural-language configuration layer in their listings. MindStudio is included because its listing explicitly describes a no-code visual builder for AI agents. Prompt-driven task products that do not let a user build or configure a reusable agent are not included.

## How this list is built

A tool earns a place here only when its Published listing documents a no-code path to building or configuring an agent. The path may be a visual canvas, a drag-and-drop or node-based flow builder, or a plain-English configuration layer that produces a working agent without code. Listings that only accept a task prompt do not qualify, because using an agent is different from building one. Code-first frameworks with an optional visual studio are included, with the distinction stated in the note. Products whose primary buyer is a developer or an infrastructure-conscious enterprise are included when the listing still documents a real builder. The page is deliberately cross-cutting. A tool can qualify because of its workflow interface, its visual agent canvas, or its prompt-to-agent configuration, even when the surrounding product is a framework, a coding agent, a support platform, or a voice platform. Membership is checked against the current listing rather than a site tag.
