Micracode

Micracode is an open source, local first AI app builder that runs as a desktop application. A user describes an app in plain English, such as a habit tracker or a REST API for todos, and an AI agent writes, edits and runs the code in real time. The output is ordinary editable code that the user owns. It runs natively on the user's machine, and the site states that code and API keys never leave the desktop. It works with any OpenAI compatible model, so users bring their own model, and it supports React, Vue and Svelte projects with one click deployment. The project is MIT licensed and community built, with source on GitHub, and can be self hosted or modified. The vendor presents it as an open source alternative to Lovable. Micracode suits developers and makers who want prompt driven app building without a hosted platform and without lock in to one model provider. Follow up requests such as adding Google login, switching to dark mode or turning a page into a Stripe checkout are handled by the same agent. The app can be downloaded for free. Because it uses the user's own model, any model usage costs come from the provider the user chooses. The site publishes no paid plans.
