Questions & Answers

As answered by people managing 4thewords 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.

  • Word Count Accountability/Writing App??
    There's 4thewords, where they gamify writing. I've not tried it but it looks interesting. Source: about 3 years ago
  • Executive Dysfunction
    Yes, I'm the same way. Two things have helped me. 1. Using the Pomodoro technique. You can find timers online and they tick while you are doing whatever, which I find helps me stay on track. I do 30 minutes with 5 minutes break. 2. 4thewords.com is a really cool gamification system for writers. You basically fight monsters while you're writing. It's amazing how well it keeps you on track! Also, there are some... Source: over 3 years ago
  • Where you write?
    I use 4thewords.com with Scrivener for organisation and notes, but it really depends on what works for you. I like the gamification of 4thewords because it helps me focus, other people prefer options where they can completely turn off their wifi for fewer distractions. There are people who still write entirely by hand for their first drafts because it helps turn off their inner editor. Try a few options and see... Source: over 3 years ago
  • Hello, I'm Celia Lake. I write cosy historical fantasy romances. Ask Me Anything today!
    My word count went up substantially when I stopped commuting every day in March of 2020. These days I'm in the office 2-3 days a week, but I've kept the words up, and average about 2K a day (though there are days I do a lot less and some I do more). I draft on 4theWords, so there is a bit of gamification there - can I get through this word battle to defeat this monster, etc. Source: over 3 years ago
  • Campfire Writing?
    I use 4TheWords more often than some of the other ones lately, and it's sorta fun too. They've got a thirty day trial and plenty of events that give you additional time for free (especially NaNo). Also worth a check if some of the other software doesn't tickle your fancy.
