WebhookWarden: Flaky Webhook Delivery Debugger & Replay Console

The Problem

Solo developers integrating Stripe, GitHub, Twilio, and similar services repeatedly report on HN and r/webdev that webhook failures are invisible until a customer complains — there's no unified place to see which webhooks failed, why, and replay them safely. WebhookWarden acts as a smart proxy layer that logs every inbound webhook, surfaces delivery failures with root-cause hints, and lets you replay any event against staging or production with one click. It eliminates the painful 'manually curl-ing old payloads from Stripe's dashboard' workflow that indie founders describe as a weekly time sink.

Target Audience

Solo developers and small SaaS teams who integrate third-party APIs and lose hours debugging silent webhook failures

Monetization Angle

$12/mo for up to 50k events/month; $39/mo for 500k events — usage-based with a free tier of 5k events

Recommended Tech Stack

Why Now

The explosion of event-driven SaaS architectures and AI-triggered webhooks has made webhook reliability a daily pain point, yet no lightweight indie-priced tool owns this space.

MVP Scope

A proxy URL that logs inbound webhooks, displays payload + headers + response code in a dashboard, and has a single 'Replay' button.

AI Angle

AI classifies the failure reason (auth mismatch, payload schema drift, timeout) and suggests the exact fix, saving the 20-minute Stack Overflow loop.

Primary Risk

Ngrok and Hookdeck have overlapping features — differentiation must be laser-focused on the replay + root-cause debugging angle rather than tunneling.

Validation Checklist

• Post 'How do you debug failed webhooks?' in r/webdev and r/indiehackers and measure response volume
• Search HN for 'webhook replay' and 'webhook failed' to quantify complaint frequency
• DM 10 indie SaaS founders who mention Stripe or Twilio integrations and ask about their webhook debugging workflow
• Build a landing page with a waitlist and run a $50 Twitter/X ad targeting 'indie hacker' + 'Stripe developer' to measure signup rate

Who Would Pay For This

Likely buyers are engineering teams, platform leads, developer-experience teams, and technical founders. Start with Solo developers and small SaaS teams who integrate third-party APIs and lose hours debugging silent webhook failures and look for teams already spending time or money on this workflow.

First 10 Users

Find the first 10 users by searching for recent complaints around "developer tools debugging" in Hacker News, developer communities, GitHub issues, and niche Slack or Discord groups. Offer a concierge version first: manually solve the workflow for a few users, then automate only the repeated steps.
