Hey Product Hunt! 👋
Handling background jobs and webhooks as a solo founder has always been my biggest point of failure.
Whenever a Stripe payment webhook failed or an email cron crashed in one of my previous projects, I had to drop everything. I’d have to dive into messy server logs, find the broken JSON payload, write a quick script to replay it, and pray it worked. It was incredibly stressful and broke my coding flow every single time.
I decided to "scratch my own itch" and built Underlayer. It’s a Task Scheduler and Event Bus, but the feature I'm most proud of is the built-in visual Dead Letter Queue (DLQ).
If a webhook or cron fails in production, Underlayer catches the broken payload. Instead of touching the CLI, you can open the failed event, fix the missing comma or wrong ID right there in our built-in editor, and hit "Retry". It acts as a safety net for your backend infrastructure.
I built this solo using Next.js for the frontend, Supabase for auth/db, and C#/.NET for the backend to ensure it handles high-throughput, concurrent background jobs flawlessly out of the box.
I’d love your brutal, constructive feedback on the UI, the onboarding flow, or the architecture itself. I will be hanging out in the comments all day, so please drop your questions, feedback, or technical roasts below!
Cheers! 🚀
