Best Pickaxe Alternatives and Competitors (2026)

I have a few questions after reading the FAQs:

1. Can branded agents support one-time payments instead of subscriptions?
2. Can I use external checkout and manually grant/revoke access?
3. Are external customers unlimited and separate from the 5 team seats?
4. Does each customer have private, persistent memory, files, and chat history?
5. Are the 12,000 credits shared among customers? Can I set individual limits? What happens when credits run out?
6. Are there additional per-customer fees, or are those exclusive to your separate white-label service?
7. Are branded pages, payments, and access controls fully functional today, independently of the upcoming marketplace?

Thanks!
