Stack AI
Build AI agents and apps with no code.
Free plan available; paid tiers are listed on the website.

Stack AI is a no-code platform for building AI agents and automations that plug into your own data and business tools. It turns the pieces of an AI workflow into blocks you can connect visually.
What it does
With Stack AI you design AI workflows by linking language models, documents and connected apps on a visual canvas. From there you can build agents that handle support questions, run research, or automate internal processes, then deploy them as apps or APIs for your team to use. Because it is no-code, you focus on the logic rather than the plumbing.
Who it’s for
Stack AI suits teams and businesses that want to put AI to work without a large engineering effort. The visual builder makes it approachable, while the integrations and deployment options give it real reach. More advanced workflows still reward careful planning and testing. A free plan is available, with paid tiers listed on the website.
