What Websim provides
Prompt to interactive experience
Describe a game, tool, or experiment; Websim generates runnable web experiences you can test immediately.
Share, like, and remix feed
Post creations to a discovery feed so others can play, comment, tip credits, or remix your project.
AI abilities without API keys
Enable chat, image, or voice-style abilities inside projects without wiring your own model keys for casual experiments.
Multiplayer and social toys
Many experiences support multiplayer or comment-driven interaction—useful for demos and playful prototypes.
How developers use Websim
Start from a prompt or template
Open Create, describe the experience (or pick a template), and generate a first playable version.
Iterate in the browser
Prompt refinements, break things on purpose, and re-generate until the interaction feels right.
Post to the feed
Share when ready so others can play, remix, or tip credits—useful for feedback loops.
Watch daily generation caps
Plan heavier experiments around free daily limits, or upgrade when you need premium models and higher quotas.
Who Websim is for
Developers prototyping interactions
Spike unusual UI or game ideas before committing to a repo or design system.
Educators and learners
Teach “describe → run” creativity without local toolchains or API billing setup.
Indie makers shipping toys
Publish playful tools and remixable experiences where a social feed is part of the product.
When Websim is the right pick
Licensing and platform notes
- Cloud-hosted playground
- Generation and hosting run on Websim’s servers. Projects live in their ecosystem—confirm export and ownership terms if you need code outside the feed.
- Freemium generation caps
- Free tiers gate daily generations and model access. Paid plans raise caps and unlock premium models—confirm current numbers before batch experiments.
