Practical overview

When it fits

Use Sim when you need to construct and manage connected AI-agent workflows, especially for internal automation or knowledge access, rather than only consume a prebuilt assistant.

Who it is for

  • Teams building internal AI automations
  • Developers creating connected agent workflows
  • Organizations exploring self-hosted knowledge-base assistants

Documented uses

  • Build AI agents and multi-step workflows
  • Connect agents with business tools, databases, files, knowledge bases, and structured table data
  • Deploy and monitor agent workflows
  • Create low-code or visual automations for internal use
Before you choose

Requirements & limits

The repository is public and identifies an Apache-2.0 license. The technical profile lists web, macOS, self-hosted, and cloud platforms.

  • Whether visual, conversational, or code-based workflow construction matches the team’s development style
  • The need to connect agents with business tools, databases, files, knowledge bases, or structured data
  • Whether Apache-2.0 open-source licensing and TypeScript implementation fit the project
  • Whether web, macOS, self-hosted, or cloud access aligns with the intended deployment approach

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a self-hosted Sim deployment with the interactive wizard

Create a local Sim deployment, provision its database and secrets, connect a Chat API key, and start the published Sim images.

Before you start

  • Node.js 20 or newer
  • Docker

Steps

  1. Run the command below to start the interactive setup wizard.

    Documented command
    npx sim-setup

  2. Let the wizard create the sim/ deployment directory, provision the database, generate secrets, write .env, and connect a Chat API key.

  3. Let the wizard start the published Sim images with Docker Compose.

  4. When setup finishes, open http://localhost:3000.

Expected outcome

A self-hosted Sim deployment is started locally and is available at `http://localhost:3000`.

Guide limitations

  • The wizard creates a deployment directory and does not clone the repository.
  • Source-only local development and Kubernetes modes require a cloned Sim repository and bun run sim-setup.
  • The evidence documents setup and opening the local interface, but not building or running a specific workflow.
