The top no-code AI agent builders, ranked
KaHappy
Editor’s choiceBest overall for small businesses & professionals
KaHappy is a no-code AI agent & chatbot builder for small businesses and professionals — plus ready-made AI expert tools. You can build a custom, branded AI agent in minutes, train it on your own content, and embed it on any website with a single snippet. On top of the builder, KaHappy offers premade AI expert tools (like a resume builder and lesson plan generator) that most competitors don’t. It starts free with 100 monthly credits, with paid plans from $15/month.
Chatbase
Good for document-trained support bots
Chatbase is a popular AI chatbot builder that focuses on training bots on your documents, help center, and website content. It’s a solid choice for teams that mainly want a support bot answering from a knowledge base, though its paid plans start higher and it doesn’t include ready-made expert tools.
Botpress
Best for developers who want deep control
Botpress is a flexible, powerful platform for building conversational AI agents with detailed flow control. It offers a lot of customization, but the learning curve is steeper and it leans more technical — better suited to teams with developer resources than true no-code beginners.
Tidio
Best for e-commerce live chat + bots
Tidio combines live chat with chatbot automation and is well-liked by e-commerce and support teams. It’s easy to start with, though its AI features are geared toward support/sales chat rather than building broader custom AI agents or expert tools.
BotPenguin
Best for multi-channel messaging
BotPenguin lets you deploy chatbots across your website and messaging apps. It’s a capable multi-channel option, with pricing and features that scale by usage and channels.
