A regular JFH-CODE build uses 2 JFH Credits: a shared design and a JFH-CODE program. Additional provider requests or repairs can use more JFH Credits; TypeScript comparison is introduction-only.

JFH-CODE relative to TypeScript
MeasurementJFH-CODETypeScriptDifference

Both programs implement the same shared HTML, CSS and behavior, so program code is the compared result; whole app adds the shared HTML and CSS. Generation counts the first program call (and a plain-text retry if a model rejected the JSON schema); with repair adds the automatic repair call. Tokens are the provider’s reported usage, including the instructions and language guide; rejected requests count as calls without tokens. Times are provider and compiler durations, not app runtime speed. The example is a demonstration.

○ Functional comparison: the shared behavior checks run automatically in an isolated copy of each preview. Passing checks cover the listed steps, not every possible behavior.

Once your first AI request is securely recorded, this screen will show the exact next grant date and time in your local time zone. Only the server/database determines the schedule.

H-CODE PRO · YOUR OWN API KEY$10 / month

No JFH-CODE platform credit limit with an active Pro subscription. Your AI provider's usage charges and rate limits still apply.
