Woopy is incident response for developers who do not run a NOC. When your production app throws an exception, you get a push notification on your phone within seconds - and next to the alert there are buttons you define yourself: "Restart worker", "Clear cache", "Retry job". One tap fires an HMAC-signed webhook (Standard Webhooks spec) back at your infrastructure, and the incident is handled before you find a laptop.
Integration is one npm package (@woopysdk/node, ISC licensed) with a single call in your catch block, or a plain HTTP POST from any language. Signup to first push takes under 2 minutes. Every action run is logged with its HTTP status, so "did the restart actually go through?" always has an answer.
Woopy is deliberately NOT a full incident-management platform: no on-call schedules, no escalation policies, no phone calls. It is built for solo developers, freelancers maintaining client apps, and small agencies - and priced accordingly: per app, not per seat. Free for 2 apps; Pro $9/mo for 10 apps; Team $49/mo flat for 50 apps with unlimited responders.
Project Euler WoopyWoopy's answer:
Woopy is built by a solo founder and a frontend co-founder, in public. The itch: when you maintain production apps for clients, you find out about crashes from the client, and fixing anything means finding a laptop. Existing incident tools assume a team and a NOC; error trackers tell you what broke but give you no way to act. Woopy closes that loop - a push within seconds of the exception, and a button next to it that actually fixes the problem.

Woopy's answer:
Woopy pairs every crash alert with one-tap remediation actions. Alerting alone is a commodity - what makes Woopy different is what happens after the push: next to the alert there are buttons you define yourself ("Restart worker", "Clear cache", "Retry job"), and one tap fires an HMAC-signed webhook (Standard Webhooks spec) at your infrastructure. The incident is handled from your phone, before you find a laptop. Every action run is logged with its HTTP result, so "did the restart actually go through?" always has an answer.
Woopy's answer:
Most incident-management platforms (PagerDuty, Opsgenie, Zenduty) are built for teams running a NOC: on-call schedules, escalation policies, per-seat pricing. If you are a solo developer or a small agency maintaining client apps, you pay for machinery you never use. Woopy deliberately skips all of that and adds the one thing they lack: remediation actions next to the alert. Pricing is per app, not per seat - free for 2 apps, Pro $9/mo for 10 apps, Team $49/mo flat for 50 apps with unlimited responders. Integration is one npm package or a plain HTTP POST; signup to first push takes under 2 minutes.
Woopy's answer:
Solo developers, freelancers maintaining client apps, and small agencies - people who are personally responsible for production but do not run a NOC and cannot justify per-seat incident-management pricing. If your "on-call rotation" is just you and your phone, Woopy is built for you.
Woopy's answer:
Backend: Ruby on Rails (API mode) with PostgreSQL, Sidekiq and Redis. Web dashboard: React with Vite. Mobile apps (iOS and Android): Capacitor, with push delivery via APNs and FCM. SDK: Node.js (@woopysdk/node, ISC licensed), plus a plain REST API for any language. Outbound remediation actions follow the Standard Webhooks spec with HMAC signatures.

I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 8 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
