Web UI

Overview

Dexto web UI is the easiest way to test out different LLMs, MCP servers, prompts, and more!

Once you're satisfied with a specific combination, save it as a Re-usable AI agent built with Dexto, and deploy the agent anywhere.

All this is possible because Dexto sees any valid config file as a re-usable AI agent.

Dexto web UI also stores your conversation history locally so it remembers your past conversations!

Start dexto web UI:

dexto

This opens the Web UI at http://localhost:3000 in your browser (web is the default mode).

The API server runs on port 3001 (web port + 1).

Use a different port:

dexto --web-port 3333

This starts the Web UI on port 3333, with the API server on port 3334.

Customize API port independently:

dexto --web-port 3333 --api-port 8080

This is useful for custom port configurations or when integrating with existing infrastructure.

When installed as a global CLI, dexto stores conversation history in ~/.dexto folder by default

In development mode, storage location defaults to<path_to_dexto_project_dir>/.dexto
