I built a free tool to instantly find your top competitors (just paste your domain)

Hello fellow indie hackers 👋

I built a simple tool to help founders figure out who their actual competitors are! You know... the ones your potential customers already know and compare you to.

Just paste your domain, and we generate a focused list of 10 competitors with names, sites, and a quick positioning note for each.

Why I built it: I run a competitor monitoring tool (https://champsignal.com), and I realized that before people can monitor competitors… they first need to find them. This is harder than you think for people that have not been around for years aha

So I made this as a free tool, no signup needed:
👉 https://champsignal.com/tools/competitor-finder

It's been so fun to make I hope it helps a bit.

Would love any feedback, especially if the results feel off for your product. Curious to hear how you'd improve it!

Try with Stripe, Notion, Bubble, etc.

    Just tried it out, and it's definitely better than when i ask ChatGPT. We're focused on Shopify, and the competitors were all focused on Shopify too. Congrats on this tool!

    1. 1

      Yeah thanks, many iterations went into it 😄🙏

  2. 2

    Awesome tool. Good to see how similar companies are doing.

  3. 2

    That's a neat tool! How do you generate the list and handle edge cases like multi-product companies or brand name collisions, and how often do you refresh it. It would help to let me nudge results with a short description or keywords, add region or ICP filters, show a "why this match" overlap score, and offer CSV or API export.

      Thanks :D

      How do you generate the list and handle edge cases like multi-product companies or brand name collisions, and how often do you refresh it.

      It's mostly LLM based, so hoping that with high enough reasoning, it can handle those use cases.

      It would help to let me nudge results with a short description or keywords, add region or ICP filters, show a "why this match" overlap score, and offer CSV or API export.

      Awesome suggestions. I'm curious as to why you would need this. Would it be useful to your personally, or do you just think it would be cool to have in general?

      1. 2

        Both for me and broadly useful :)
        When you are launching, you need to know not just who is similar but why and where to differentiate. Region or ICP filters plus a "why this match" score make it actionable, and CSV or API export lets me plug it into research.

        btw we could partner up. I am building HustleAdvisor, a social network for entrepreneurs. If you join the waitlist now, at launch in 17 days you could publish a short post about building Champsignal on our platform and we will boost it in the main feed so more people find it.

        You get: more users
        We get: an entrepreneur on board

    That's a really fantastic idea. I'm going to check that out.

    Great work on this competitor finder! I recently built a TI-84 calculator emulator web app to help students use graphing calculators online. It's always inspiring to see tools that simplify tasks. Have you thought about adding competitor examples to help users interpret the results?

    1. 1

      Hey! Thanks for the comment. What do you mean with competitor examples?

  6. 2

    Hey Maxime 👋

    Just tried out the competitor finder — really impressed by how quick and clean the experience was. I tested it with a couple of well-known tools and the results were surprisingly relevant.

    I can definitely see how this helps early-stage founders who aren’t fully clear on who they're really competing with (especially from the customer’s perspective). It's one of those simple-but-valuable tools that solves a real problem.

    One suggestion: would be interesting if the tool allowed users to vote on how accurate the results are, or submit their own competitor list as feedback — might help you fine-tune the algorithm over time.

    Anyway, thanks for sharing this for free — bookmarking it for future use!

    1. 2

      Thanks, great feedback! Will definitely consider adding using user feedback 🤝

  7. 2

    Smart move building this as a free tool to drive awareness for ChampsGnl! The "finding competitors before monitoring them" insight is spot-on - it's one of those obvious-in-hindsight problems.

    Just tested it with a few domains and the positioning notes are really helpful. The LLM approach is clever since competitor landscapes change so quickly that maintaining static databases would be a nightmare.

    1. 1

      Yep! Hopefully will bee good for SEO.

      Sweet thanks!

  8. 2

    Tested with our domain - the top 10 competitors listed were surprisingly relevant to the procurement market. As the first AI-powered sourcing platform, Accio understands how crucial accurate competitor intelligence is for businesses. Your tool's ability to quickly surface comparable players could be valuable for suppliers looking to benchmark themselves. The positioning notes were particularly useful for understanding market differentiation.

  9. 2

    I love the idea, but I tested it with my own domain. The app suggested main competitors like Shopify, WordPress, and similar platforms, but my website is neither a CMS nor an e-commerce tool, and it has a very niche purpose.

    I thought it might be useful to share this feedback. I’m not sure how often you see cases where "key competitors" are missing, but maybe the output could be more targeted and avoid suggesting competitors that are too broad or unrelated.

    1. 1

      Yeah sometimes it misses the mark. Also sometimes if you try it a second time in a row it works (it's LLM-based, so it's non-deterministic).

      Can you share your domain, and who your real competitors are? Would be useful for debugging.

      1. 2

        Sure, here’s my domain: https://gachari.com/
        I actually don’t know of any competitors, which is why I was curious to see what might come up. 😁

        1. 2

          Woah that's so cool 🥹

          Two thoughts:

          • There's not really any copy on your website, so it's hard to the LLM to even understand what it is
          • There's a big possibility that you simply don't have competitors 😅 I don't know the space enough to know if there are similar games
          1. 2

            I'm building a landing page, that should give more context. I'll try again once it's done.

            Thanks for your job and insights anyway ! 😊

        2. 1

          Hey! Were you able to get your niche competitors?

  10. 2

    Not sure how to use the demo. I mean it is just some admin panel. So what? How do I test the real "magic"?

    1. 1

      Are you using the right URL? https://champsignal.com/tools/competitor-finder. Then just put in your URL 😁

      1. 2

        Thanks! It works! My bad, not sure how I missed it.

        Update:

        I went to your website and again and couldn't find that link you sent above. The demo button leads to that same admin panel and "try now" in the header to register / login form.

        1. 1

          Yes, if you want to find the link on the website it's in the footer, under "Free Tools" :)

    this immediately reminded me of something i came across on reddit ... a project called startupsonar. very different use case, but same spirit: removing the guesswork from early-stage strategy.

    champsignal shows who your audience compares you to. startupsonar listens to what your potential audience is complaining about. both tools are grounded in signal, not gut feel.

    just a small thought for champsignal
    let users tag or group competitors (direct, alternative, influencer) and add quick notes. then allow exporting the full list (with tags and notes) to csv or notion.

      This is on the roadmap as well 😁

      Great feedback, I'll definitely implement that. CSV export has been a feature on my other free tools, so won't be hard to add 🫡

      1. 2

        Wish you all the best 😊

  12. 2

    That's competitive. Interresting idea!

  13. 2

    The issues it has 3 days trial initally u can run it free

    1. 1

      What do you mean? Competitor Finder is an entirely free tool.

  14. 1

    "Great tool! I love that it focuses on customer awareness, not just SEO keywords.

    Speaking of tools, for any founders here looking to extend their runway or model passive income for stability, you'll eventually need a good financial calculator.

    I highly recommend the free dividend calculator tool. Just search Google for the full name: dividendcalculatoronline

  15. 1

    Just tried it out - I love how fast and relevant results are. How do you handle niche products with few direct competitors?

  16. 1

    Tested this tool - found it quick & spot on. Congrats!

  17. 1

    I've just launched the Beta for new product called Toad and it instantly found the competitors.

    Interestingly, the results were right when I had www. at the start but when I didn't, it went off piste
