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.

D (Programming Language) features and specs

  • Performance
    D is designed to be a high-performance systems programming language, offering performance comparable to C and C++ through native machine code compilation.
  • Expressiveness
    D features a rich standard library and modern language constructs, such as garbage collection, first-class arrays, and advanced templating, making it easier to write expressive and maintainable code.
  • Memory Safety
    D offers optional garbage collection along with manual memory management. This hybrid approach can help in developing safer applications by reducing memory-related errors.
  • Interoperability
    D can easily interoperate with C API, enabling seamless integration with existing C libraries and systems. It also supports better C++ interoperability compared to other languages.
  • Built-in Unit Testing
    D has built-in support for unit tests, allowing developers to write and run tests as part of the language itself, facilitating test-driven development.
  • Concurrency
    D offers built-in concurrency support with message passing, similar to the actor model found in languages like Erlang, making it easier to write concurrent and parallel programs.

Possible disadvantages of D (Programming Language)

  • Adoption
    D is not as widely adopted as other languages like C, C++, or Java. This limited adoption means fewer libraries, frameworks, and community support.
  • Toolchain Maturity
    While D's compilers and tools have improved over the years, they may still lack the maturity and feature set of more established languages, which can affect developer productivity.
  • Learning Curve
    D's richness and combination of paradigms (such as imperative, object-oriented, and functional programming) can present a steep learning curve for new developers.
  • Garbage Collection
    Although D offers optional garbage collection, its reliance on it for memory safety might be seen as a drawback for real-time system development where deterministic memory management is crucial.
  • Ecosystem
    The ecosystem for D is less vibrant compared to more popular languages, leading to potentially fewer third-party libraries, tools, and resources.
  • Standard Library Documentation
    The standard library documentation can be inconsistent or less comprehensive compared to other languages, making it difficult for developers to fully utilize all features of the language.

Analysis of D (Programming Language)

Overall verdict

  • Overall, D is a solid programming language choice that balances performance with productivity. It may not be as widely adopted as some other languages, but it has a dedicated community and continues to evolve, making it a viable option for various programming tasks.

Why this product is good

  • The D programming language is considered good by many developers for various reasons. It combines the performance and low-level control of C/C++ with the expressive power and ease of use found in modern languages. D offers features like garbage collection, first-class functions, and compile-time function execution, providing both speed and flexibility. Its interoperability with C, the convenience of a powerful standard library (Phobos), and the availability of packages via the DUB package manager make it a practical choice for systems programming, application development, and rapid prototyping.

Recommended for

  • System programming enthusiasts looking for an alternative to C/C++
  • Developers interested in writing high-performance applications
  • Programmers who appreciate modern language features and strong community support
  • Projects requiring seamless C integration
  • Individuals looking for a language that supports easy code maintenance and scalability

Questions & Answers

As answered by people managing D (Programming Language) 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.

    I've spent 2 weeks (2-4h per day) to make D language[1] version of Sciter SDK [2] Choice of AI "tooling" was by accident - typed something like "how to define copy constructor in D for custom structure" in Microsoft's Copilot in Edge browser that gives context for AI.
