Your exported Spark app can't npm install
: it depends on the private @github/spark
package. Upload your export, see exactly what breaks for free, and get a working repo back.
Follow-ups
Three things: spark.kv and useKV (your data), spark.llm and spark.llmPrompt (AI features, already broken since GitHub Models retired), and spark.user (your GitHub identity). The scan below tells you exactly which files use which.
You pay once, we rewrite every @github/spark import to a local replacement (localStorage for data, your own API key for AI, a stub for auth), then hand you back a repo that installs and builds normally.
Payments handled by Polar. Your code is processed in memory to run the migration and is not stored afterward.
