String.com
AI agent for building AI agents
Visit website →About
String.com is an AI agent that builds other AI agents. The user describes a task in plain language and String assembles the workflow, connects the needed apps and APIs, runs it, and deploys it, without the user setting up servers or writing integration code.
Built agents can be edited by prompt, tested in place, and put on a schedule or triggered by events. The platform handles credentials, retries, and logging so a working agent keeps running unattended.
It is aimed at operators, founders, and technical teams who want to automate real processes, such as lead routing, research, or data cleanup, faster than building each automation by hand. A free tier covers early experiments.

Why we picked it
String.com earns its spot for the edit-by-prompt loop after deployment — a built agent staying adjustable through plain language rather than needing you to reopen a workflow builder is worth naming for anyone who's abandoned a no-code tool the moment something needed tweaking.
