Possible disadvantages

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.

Questions & Answers

As answered by people managing Uppcoder and StackBlitz.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

Which are the primary technologies used for building your product?

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've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

    StackBlitz claims to allow you to code the future in your browser. And after trying it, I’m confident you’ll agree that this web application is extremely useful for coders.
