Key Benefits
Faster Development
Skip repetitive coding tasks and generate ready-to-use code instantly, so you can focus on building core features instead of boilerplate.
App Scalability
To add admin features for a new entity, all you need is a single C# class, everything else is generated for you.
Human Error Reduction
By generating proven and pre-tested code automatically, the chances of manual errors are greatly reduced.
Consistency
Automatically applies the same patterns, conventions, industry standards and best practices to ensure a uniform codebase every time.
Maintainability
Generated code is correct and separated, making code reviews easier and keeping your project structure clean.
Business Logic Focus
With Spiderly handling the scaffolding, you can forget about boilerplate code and focus on the core business logic that truly matters.
A Word from the Founder
Through my work in companies and side projects, I saw the need for a tool to generate repetitive boilerplate code. The things I wrote over and over again caused me stress because I wasn't learning anything new. This was especially frustrating if I made a simple mistake during that manual work, or worse, had to do a code review for someone with a completely different writing style than mine.
Spiderly is valuable in the era of LLMs like ChatGPT, Claude, Gemini, and Grok, because these tools still lack the ability to build deeply structured projects. Spiderly handles the big picture and helps by letting you isolate small chunks of specific business logic, for which you can then ask LLMs to assist you more effectively.
Unlike most generators that are only useful at the beginning of a project, Spiderly allows you to work incrementally. You can evolve your models and application structure naturally over time without needing to know everything upfront.
If you choose to use the Spiderly library, you have my full support. Just open an issue or start a discussion on GitHub, and I'll respond within a few hours.
