GitHub Spark alternatives for personal apps
Looking for a GitHub Spark alternative is a different job when you already have an app you use. Before choosing a new builder, work out what you want to keep. The app's code, the information you've entered, and its AI features may each need a different next step.
An app can still open and be partly broken
GitHub's August 4, 2026 announcement ended new Spark users and app creation that day, with access to export existing apps through August 31. It said already-deployed apps would continue to work. The export deadline has now passed.
The same announcement identifies a separate issue: the GitHub Models service behind Spark's llm() function retired on July 30. An app could therefore still load while a feature using that function no longer worked. GitHub says those calls need a replacement provider, with the user's own key and billing.
That makes it worth checking what your app still does before assuming the whole thing needs replacing. Try opening saved information and using the ordinary controls, as well as any AI feature. Keep notes on where it fails.
If you saved the project
An exported repository gives you a place to continue. Make a separate working copy before asking another coding tool to change it. Look for the instructions to run it and identify any services it expects: a database, sign-in, storage, or a model provider.
The source files may describe how to read a book list without containing the books you've entered. Check where those records live and what access you still have to them. A copy of the code should never be your only evidence that the data is safe.
Continuing that project with coding assistance may preserve work that a new builder would have to recreate. Before choosing a host, get the app running in a development environment and check its ordinary workflow. Then deal with the dependencies that need replacing. This gives you a smaller problem than changing the builder, hosting, and app behavior at once.
When a small rebuild is reasonable
Suppose the useful part was a reading list with a note about who recommended each book. You may prefer to recreate that simple workflow rather than maintain the whole exported project. First write down the fields, filters, and actions you used. Screenshots help preserve details such as which note appeared beneath a title.
Make a separate plan for existing records. Even if another app has fields with the same names, dates, statuses, and relationships may need conversion. If you no longer have the code, preserve what you can through the app's available export or viewing features before abandoning it.
Kaddy is an option for rebuilding small personal tools in a shared home. It doesn't import Spark projects or automatically move their data. The first-app guide can help turn the workflow into a request; use fictional records while checking the replacement.
Choose an alternative around what remains
If you have code worth continuing, investigate a development environment that can work with that actual project. Check its dependencies rather than assuming a general “import” feature guarantees compatibility.
If you're starting again, Lovable and Replit are worth considering for an independent application. A local builder such as Dyad may appeal if having project files on your own machine is now a priority. Kaddy fits a collection of smaller personal tools.
Whichever route you try, make recovering your information part of the trial. Enter a few sample records, find how to retrieve them, and understand what depends on the service continuing to run. That is a useful lesson to carry into the next app.
