My GPT has no Actions. Do I need Plugferry?
No. Paste the instructions into a Claude Project or a skill and upload the knowledge files. Plugferry is for the Actions.
What counts as a plugin?
One project with a bridge on its permanent address. One project in testing on a Plugferry subdomain is free.
Is my own domain extra?
No. Every public plugin should live on its own hostname, because a listed plugin’s address can never change.
What happens above 100,000 calls?
Calls keep working. Each started 100,000 calls above the allowance costs $4, invoiced on the 1st for the month before.
Is there a spending cap?
Yes. By default calls stop at five times the allowance, so a runaway plugin can’t run up a bill. The owner can raise the cap up to 50 times the allowance.
What happens on Test after 1,000 calls?
Calls stop until the next month starts. Nothing is charged.
Where do I pay?
In the dashboard, after you sign in. Payments are handled by Stripe; Plugferry never sees your full card number.
Can my plugin sell through Plugferry?
No. Plugins may not sell anything, and the plugin links only to an informational page about Plugferry.
Can I leave?
Yes. Point your hostname at other hosting; the listing stays yours.
Do you guarantee approval?
No. We mirror OpenAI’s published rules and the refusals we have seen, but review is OpenAI’s decision.
