Practical overview

When it fits

Use Blankspace when you want a browser-oriented workspace for AI-assisted app development or a codebase to adapt into a self-hosted coding assistant.

Who it is for

  • Developers who want an AI agent to generate or debug application code.
  • Builders looking for a self-hostable browser-based app-building interface.
  • Developers interested in adapting a React and Vite AI coding-agent project.

Documented uses

  • Generate application code from a request.
  • Debug code with agent tools for reading, writing, editing and validating files.
  • Manage project files through assistant-agent operations.
  • Review work in an editor and preview alongside chat.
Before you choose

Requirements & limits

The README links to a live web app and documents self-hosting. Local development requires OpenAI and Google AI API keys; Firebase credentials are listed for authentication and storage. No pricing details are provided.

  • The code agent is documented with Gemini models and file tools; chat and assistant agents are documented with OpenAI models.
  • The frontend uses React and Vite, while the backend is described as Vercel serverless functions.
  • Firebase is part of the documented authentication, storage and data architecture.
  • Apache-2.0 licensing permits an open-source development and adaptation path.
  • The README marks the web app as the current focus and lists iOS and Android as roadmap items.

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 Blankspace for local development

Prepare the project and start its documented local development server.

Before you start

  • Node.js/npm environment suitable for installing the JavaScript project
  • OpenAI API key
  • Google AI API key
  • Firebase project credentials for authentication and storage

Steps

  1. Clone the repository and change into its project directory.

  2. Copy .env.example to .env.local and add the required API keys; configure the listed Firebase credentials for authentication and storage.

  3. Run the command below, then the command below.

    Documented command
    npm install
    Documented command
    npm run dev

Expected outcome

The README directs developers to open the local development app at `http://localhost:5173`.

Guide limitations

  • The guide covers local development startup, not a complete production deployment.
  • Firebase credentials are listed for authentication and storage; the README does not specify which functions remain available without them.
