Ackflow, the webhook safety net
A focused webhook layer that acknowledges events quickly, preserves their full context, retries failed deliveries, and lets developers replay them.
- For
- Developers managing unreliable webhook integrations
- Worth noticing
- Retry schedules are shown as a concrete sequence, from one minute after failure to a final two-hour attempt.
Field notes
The page frames webhook handling as a staged recovery process rather than a dashboard-only problem: acknowledge first, preserve the event, then retry delivery on a schedule. Its examples include a Stripe checkout.completed event, a 30-day retention period, and notifications through Slack or Discord. The advertised plans scale from 50,000 to 2.5 million events per calendar month, while the product is described as opening to a small developer cohort.
