Websim

What it is

Websim lets anyone build small games, simulators and web apps by describing them to an AI agent, with no setup or downloads. Projects run in the browser and are shared on a public feed where others can play them, leave comments and remix them into new versions. Recent updates added smoother multiplayer, better database support, group projects, credits for video generation and an agent that can act on comment suggestions. Creations can include AI features such as text, speech and image generation. Free models are available, and users can buy credits once, subscribe to Starter or Pro plans, or build with a connected ChatGPT account.

Editor's notes

More context from AI BirdView

Websim blends an AI coding tool with a social platform. Instead of building an app in private and deploying it elsewhere, you create directly on the site and your project lands in a feed where other makers can try it, which makes it feel closer to a creative community than a developer tool. Popular projects range from playful simulators to multiplayer games, many of them remixes of each other.

Prompt-based creation of games, apps and interactive pages in the browser
Remixing of other users' public projects as a starting point
Multiplayer and database support for more ambitious builds
AI capabilities such as text, speech and image generation inside projects
An option to build with the agent using a connected ChatGPT account

Websim is best for students, hobbyists and creative coders who want to make something fun and share it quickly, and it also works as a gentle introduction to building with AI. A practical tip: browse the top projects first and remix one close to your idea, since starting from working code is often faster than prompting from scratch.
