As answered by people managing Glitch and Uppcoder.
Uppcoder's answer:
Developers who want their stack running without setting up servers; teachers and schools who need a ready coding lab for every student and autograded assignments, often as a GitHub Classroom replacement; and organisers of hackathons and team projects.
Uppcoder's answer:
Uppcoder is made by Websson d.o.o., a small software company in Pula, Croatia. We built it because setting up a working development environment and putting an app online still takes too long, for professional developers and even more for students. It grew from hosting developer stacks into an AI app builder, coding labs for education and hackathon workspaces, all on the same platform.
Uppcoder's answer:
It covers the whole path from idea to a running app in one place: describe an app to the AI builder, or pick a framework or a ready-made app, and it runs at its own HTTPS address with its database, an editor and a terminal in the browser. The same platform runs coding labs for classes, with assignments marked by tests and LTI 1.3 for Moodle, Canvas and Blackboard, and hackathon workspaces for teams and judges.
Uppcoder's answer:
Most tools do one part: an online editor, an AI app generator, a host, or a classroom tool. Uppcoder does all of them on one account, with real stacks rather than a sandboxed toy: your framework, a real database, deploy from Git, your own domain. There is a free plan, the AI builder can be tried without an account, and hosting can be kept to the region you choose, such as Europe or the United States.
Uppcoder's answer:
Python (FastAPI) and PostgreSQL on the backend, Vue on the frontend, Keycloak for sign-in, Docker and Traefik for running and routing every app, Celery and Redis for background work, and LiteLLM in front of the AI models.

I like it! I spun up a little remixable Glitch project based on your demo so that I could play with it in a web editor. Thanks for sharing. https://glitch.com/~fullsoak. - Source: Hacker News / over 1 year ago
