Webhook Delivery Infrastructure for Small SaaS Products

Every SaaS product that sends webhook notifications to customers eventually faces the same engineering challenges: retry logic for failed deliveries, payload signing for security, delivery logs for debugging, and rate limiting to avoid overwhelming customer endpoints. Building reliable webhook infrastructure from scratch takes 2-4 weeks of engineering time. Most bootstrapped SaaS products implement basic HTTP POST calls with no retries, no signing, and no delivery visibility, leading to missed events, silent failures, and customer complaints. The wedge: a managed webhook delivery service with SDKs that add enterprise-grade reliability to any SaaS product in 30 minutes of integration.

Problem Statement

A SaaS founder adds webhook notifications to their product: when a form is submitted, POST the data to the customer's endpoint. Their implementation: a simple fetch() call in an async handler. No retries — if the customer's endpoint is down, the event is lost. No payload signing — the customer cannot verify the webhook came from the product. No delivery logs — when a customer says 'I did not receive the webhook,' the founder has no way to check. No rate limiting — if 100 forms are submitted in 1 minute, the customer's server gets hammered with 100 POST requests. After 3 customers report missed webhooks, the founder spends 2 weeks building retry logic, a delivery log table, HMAC signing, and a basic webhook management UI. That is 2 weeks not building has that grow revenue.

The Idea

A managed webhook delivery platform for SaaS products that provides retry logic, payload signing, delivery logs, and rate limiting through a simple API, replacing 2-4 weeks of custom webhook infrastructure engineering with 30 minutes of SDK integration.

Why Now

Webhooks have become the standard real-time integration pattern for SaaS products. Every product that integrates with Slack, Stripe, or GitHub relies on webhooks. But building reliable webhook delivery is deceptively complex: exponential backoff retries, HMAC payload signing, idempotency keys, delivery status tracking, and customer-facing webhook management UIs. Svix raised $16M and proved the market for webhook infrastructure. But Svix pricing starts at $75/month for 50K messages, expensive for early-stage products sending 1K-10K webhooks per month.

AI PR Triage and Review Queue for Agent-Generated Code

Coding agents now produce more PRs than human engineers on many teams, overwhelming reviewers with diffs they cannot read line-by-line. A triage system that evaluates PR risk based on code sensitivity, author verification steps, and agent conversation context lets reviewers focus on the PRs where human judgment changes outcomes. Haystack demonstrated this model, reaching strong HN traction.
