Frequently asked questions

Yes, absolutely. You can cancel any time from your billing portal. You'll keep Pro access until the end of your current billing period, then automatically move back to the free plan — with no charges.

All plugins you've already generated and downloaded are yours to keep — cancelling has no effect on files already on your computer. Your saved projects in the app will still be visible but generation will be limited to 3/month.

Pro subscribers get access to Claude by Anthropic — currently one of the best coding models available. Free users get Gemini, which is great for most plugins but Claude typically produces cleaner, more complex code with better error handling.

On the free plan, authors: [StackNest] is added to your plugin.yml file. This is just our way of staying visible — it doesn't affect functionality. On Pro, only your own name appears.

Payments are processed entirely by Stripe — we never see or store your card details. Stripe is PCI-DSS Level 1 certified and used by millions of businesses.

You need a free account (email + password) to generate plugins so we can enforce the monthly limit fairly. Signing up is free and takes under a minute.

1% for the planet

1% of every paid StackNest subscription goes toward permanent carbon removal. We contribute to certified projects that pull CO₂ out of the atmosphere — because building great tools shouldn't cost the Earth.
