Questions & Answers

As answered by people managing Jayson and CodeAva.

Which are the primary technologies used for building your product?

CodeAva's answer:

CodeAva is built primarily with Next.js, React, TypeScript, Tailwind CSS, and modern browser APIs, with a strong focus on fast front-end performance, clean UI, and browser-based developer tooling.

What makes your product unique?

CodeAva's answer:

CodeAva acts as an Automated Validation Assistant (AVA) for developers. CodeAva combines website audits, code audits, and practical developer tools in one clean workflow. Instead of offering a single utility, it helps developers and technical teams validate what they are about to ship โ€” from technical SEO and response headers to code quality, timestamps, IDs, JWTs, and debugging helpers. It is built to be fast, browser-friendly, and genuinely useful in real development and QA workflows.

Why should a person choose your product over its competitors?

CodeAva's answer:

CodeAva is designed for practical validation, not just isolated utilities. It gives users a mix of audits, developer tools, examples, and technical guides that help catch issues earlier and act on them faster. The product focuses on clarity, useful outputs, and developer-first workflows, with many core tools available without signup.

Who are some of the biggest customers of your product?

CodeAva's answer:

  • Independent Full-stack Developers
  • Early-stage Tech Startups
  • DevOps and SRE Teams
  • Open-source Contributors
  • Cybersecurity Researchers

How would you describe the primary audience of your product?

CodeAva's answer:

CodeAva is built for software developers, QA-minded teams, technical founders, agencies, and site owners who want to catch code, performance, SEO, and validation issues before they reach production.

What's the story behind your product?

CodeAva's answer:

CodeAva stands for Automated Validation Assistant. It was created around a simple frustration: too many quality checks happen too late, across too many disconnected tools. The goal is to make validation faster, clearer, and more useful for teams that ship real code, real websites, and real products.

  • Exporting shortcuts?
    You can use the Get My Shortcuts action to retrieve a shortcut as a file, and then rename it so that its extension is .plist. A shortcut is just a glorified property list (plist), which can be represented as XML (thereโ€™s also a binary format that Apple uses a lot) or converted to JSON (not always easily, but shortcuts donโ€™t have any values that would be incompatible with JSON). I like to convert shortcuts to JSON... Source: over 4 years ago
