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.

Questions & Answers

As answered by people managing ChangeDetect and Woopy.

What's the story behind your product?

Woopy'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.

Who are some of the biggest customers of your product?

Woopy's answer:

  • Woopy launched in 2026 and is currently used by indie developers and small agencies; no public case studies yet.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

Which are the primary technologies used for building your product?

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.
