    Great insights, going through a similar journey with webtoolz.dev. The SEO-first approach really resonates — our Mermaid diagram editor is starting to get organic traffic. Patience is key.

    Congratulations on reaching this milestone, Anil.

    I'm also building a free utility tool. Not for developers, though.

    I have the same concern in mind:

    • "How did you get your first users?"

    • "Any monetization tips before enabling ads?"

    My questions:

    • I see you've built multiple small tools on your website. Do you think "tool as marketing" can perform better than "content marketing"?

    • In my opinion, there are several json formatters on the internet. Do you think if a tool is really niche and unique, it can draw more traffic?

    Thanks for sharing! I'm currently at a phase when I have already a product aimed for devs and power users with a few licenses sold and I'm looking at how to scale it through SEO. I used some of the links you provided - that was really helpful! Good luck with your product!

    I'm doing indie dev interviews — would love to chat if you're open to it!

    This is super inspiring, Anil! Love how you identified a common developer pain and solved it with a clean, privacy-first approach. The fact that you hit 10k+ monthly users organically is a strong sign that you're solving a real problem — and doing it well.

    Your lessons around SEO, UX focus, and niche communities really resonate. It’s also motivating to see that you managed all this without a backend or paid marketing. Massive respect

    I’m just getting started with building small tools myself — curious to know, how do you prioritize which feature to add next when you're solo?

    Keep going! Subscribed and bookmarked your tool

    Love this, Anil — the simplicity, speed, and client-side privacy-first angle is spot on. I totally agree that small, high-utility tools can quietly rack up serious usage, especially with dev-focused audiences.

    I’m building CompliAssistant, an AI-powered HIPAA compliance assistant for small teams. JSON and structured data are everywhere in compliance too — e.g., audit logs, risk registers, access controls — so lightweight tools like yours are a huge help.

    Curious: have you had any inbound interest from teams using it for regulated industries (e.g., healthcare, finance, etc.)? Might be an interesting niche to explore for monetization.

    Thanks for sharing the transparent breakdown — super insightful 🔥

    Love the clean, focused approach! So many “JSON tools” feel bloated—this is refreshingly simple.

    Would be cool to see “copy as cURL” added—super handy for API testing. Congrats on the launch!

      Hi! I’ve added "Copy as cURL" it to the page: https://www.formatjsononline.com/json-formatter . Please check if this is what you were looking for. Any feedback is appreciated!

    2. 1

      Thank you so much! “Copy as cURL” is an excellent idea 🔥 — especially for developers working with APIs. We’ve added it to our feature roadmap and will explore adding it soon.

      Really appreciate your support and feedback! 💬 Feel free to share any other ideas you'd love to see.

    I feel that the functions are very powerful, especially powerful, and the UI looks very refreshing

      Thank you! I’m glad you found the functions powerful and the UI refreshing — your feedback means a lot! Let me know if there's anything you'd like to see improved.

    Neat tool! I also built a JSON formatter a while ago just for fun: https://json-formatter.co/, however yours seems more sophisticated :) I like the compare/diff feature! Any plans for marketing and potentially monetization?

    Nice, looks very clean.
    Lot of times, i have to filter fields in a json file and I use jq for it. That could also be a feature to think about.

    1. 1

      I added a JSON Filter tool right here: https://formatjsononline.com/json-filter — it lets you filter fields by key name or structure without writing complex jq syntax.

      Would love your feedback on it! 😊

    2. 1

      Thanks a lot! I'm happy you find it clean.
      Great idea — adding jq-like filtering would be a powerful feature for advanced users. Definitely something to consider for the next update!

    Nice project and thank you for building it. I am pretty much frustrated with existing JSON formatter. I will use it

    1. 1

      Thank you so much! I really appreciate the kind words. I'm glad this tool can be a better experience for you — that’s exactly why I built it. Let me know if you have any suggestions or features you'd love to see!

    Nice project and thanks for building it. As a developer myself, I'm going to have plenty of use cases for this

    1. 1

      Thank you! That means a lot, especially coming from a fellow developer. I'm glad it'll be useful for your work — feel free to share any ideas or feedback anytime!

    For a food experience that's centered around bold, craveable menus and aesthetic-first recipe drops, having a design language that balances vibe and usability is huge. I’ve been exploring lightweight systems like this to shape content and presentation, especially for mobile-heavy audiences coming from social.
