Signal
2 failure modes
Checkout flow failures and webhook delivery failures only. No noisy general-purpose monitoring.
Response
1 incident draft
Publish a branded status update with copy that already understands what failed.
Pace
Solo-founder fast
Setup stays tight: one checkout, one webhook, one status page, one calm source of truth.
Incident room
Founders get the story while it is still unfolding.
Investigating
Draft customer note
We are investigating a checkout issue affecting new purchases. Existing subscriptions remain active. The next update lands here as soon as we confirm recovery.

Checkout breaks
Catch the revenue path when it stops behaving.
Browser checks catch the silent Stripe flow failures that usually surface after support tickets and churn.
Webhook goes dark
Know when Stripe completes, but your app does not.
Wisp watches the acknowledgement path so you spot payment and onboarding gaps before customers do.
Status page stays current
Make the public explanation as fast as the technical diagnosis.
Turn an outage into a branded public update and founder-ready customer comms in one motion.
Founder workflow
Three moves from setup to incident-ready updates.
Wisp is intentionally narrow. It does not try to be your entire observability stack. It handles the Stripe path that breaks trust fastest.
01
Point Wisp at your Stripe moments
Add the live checkout URL, webhook endpoint, and the success signal that proves a customer made it through.
02
Run one clean validation pass
Wisp verifies the happy path, then keeps watch in the background for checkout or delivery failures.
03
Ship customer updates faster
When something breaks, you have the outage context, status copy, and a public incident draft ready to publish.
Private beta
Join the list for the first founder cohort.
Founder Plan is $29, one-time. For solo Stripe SaaS teams that want one calm place to detect payment-path outages and publish updates without bolting together three tools.
