Build Public Mini Apps in One Prompt

A platform lets you build a public mini app with its own backend using a single prompt, no revisions. You can browse all apps, delete only your own, and discover new creations at random. The project is experimental and continues while AI credits last, with updates shared on X.

Key Points

  • Create a public mini app with its own backend from a single prompt, with no revisions.
  • All apps are public; you can view any app but only delete your own.
  • The platform showcases a live, diverse stream of community-built apps and offers a random app discovery feature.
  • The project will run as long as the team’s AI credits last, reflecting an experimental, time-limited nature.
  • Users are encouraged to try building and share their favorite creations; updates are available via X.

Sentiment

The overall sentiment of the Hacker News discussion is predominantly positive and enthusiastic. Users are impressed by the platform's ability to quickly generate diverse mini-apps, with many sharing successful and functional examples. While some bugs and non-functional apps were reported, the creator's active engagement and quick problem-solving fostered a positive and experimental atmosphere, leading to a strong sense of approval for the project's innovative approach and technical execution.

In Agreement

  • Many users successfully generated functional and interesting apps, such as a primitive Slack copy, a bingo board, a blood sugar tracker, and even a basic multiplayer Doom clone, often expressing surprise and satisfaction with the results and speed.
  • The technical approach of using a multi-tenant graph database built on a single Postgres instance with an EAV table and custom statistics/query hinting was noted as 'very interesting' and an innovative solution to database scalability for lightweight apps.
  • The creator's prompt engagement and quick troubleshooting, including fixing a 'QueryValidationError' by adjusting the LLM's system prompt, were highly appreciated by the community.
  • The concept of building 'fun software for yourself' rather than complex 'production software' resonated with users, highlighting the platform's unique value proposition.
  • The speed of app generation (under 2 minutes) was a frequently praised aspect, especially given the backend and database inclusion.

Opposed

  • Several users reported encountering errors, such as client-side exceptions, blank UI sections, or non-functional buttons, indicating that the app generation is not always flawless.
  • The LLM (specifically GPT 5) was described by the creator as 'lazy' and tending to produce 'too simple' apps with 'little UI detail,' suggesting limitations in the quality or complexity of generated interfaces.
  • A bug related to unsupported subquery limits in the `InstaQL` language highlighted a current technical constraint of the system, even if the creator quickly resolved it by adjusting the LLM prompt.
