Appreciate the thoughtful response — and yeah, the integration angle is interesting. PayWatcher as a verification layer for chains QBitFlow doesn't natively cover yet makes a lot of sense architecturally. Keeps your stack lean while expanding chain support.
The primitive vs. full-stack split maps well to how developers actually buy tools: start with the smallest thing that solves the immediate problem, then add layers as complexity grows. Tip jar → PayWatcher. SaaS with MRR → QBitFlow. Both valid.
Happy to explore the integration idea — [email protected] if you want to take it offline.
You're right that it's apples and oranges. The way I see it: paywatcher solves verification, QBitFlow solves the billing lifecycle (authorization, recurring charges, cancellation, merchant dashboard). Different layers of the same stack.
Which actually makes me wonder — have you thought about integrations? A developer could use paywatcher for one-time payment confirmation and QBitFlow for subscriptions, depending on the use case. Or we could even use paywatcher as a verification layer under the hood for chains we don't natively support yet.
To your question: I think the answer is "both, depending on the builder." Someone spinning up a weekend project with a tip jar wants a primitive. Someone running a SaaS with MRR tracking and automated renewals wants the full stack. The market is big enough for both approaches.
Either way — cool to see someone else building in this space. Would be happy to chat offline if you ever want to explore how the tools could complement each other.
