What is hadzy.com

Hadzy (hadzy.com) is a web-based tool designed to help users search, sort, and analyze comments on YouTube videos. On its homepage you can enter the URL of any YouTube video, and Hadzy will load the associated comments for easier browsing. (hadzy.com)

Beyond simply listing comments, Hadzy lets you filter by date, by author, or by keywords — which can be useful if a video has hundreds or thousands of comments and you’re looking for specific feedback or discussion points. (Greasy Fork)

Hadzy also offers a “statistics” view: it can generate a kind of summary of the comment section including frequent words (a word-cloud), top questions, and top commenters. That can help you get a sense of what viewers are talking about, what they’re asking, and who’s most active — useful if you’re a content creator or doing competitive analysis. (30 Days to $100K)

Origin and Background

The service was started by two brothers who work full time as software developers. Hadzy began as a front-end prototype, and evolved into a more robust web application once they added caching to handle heavier traffic. (Patreon)

According to their own account, they built it for convenience — they wanted to make it easy to find the first comment on a video (and more). Over time, as usage grew into the “hundreds per day”, they revamped the app for stability. (Patreon)

Importantly: the project isn’t monetized (at least originally). The creators stated that infrastructure costs (hosting, servers, databases) eat into their modest monthly budget. (Patreon) That may affect long-term availability or feature maintenance.

What people like (and don’t like) about Hadzy

👍 Strengths

  • Faster comment navigation: Instead of manually scrolling through thousands of YouTube comments, you can quickly search by keyword, author, or date. That saves time. (Reddit)

  • Data insights beyond comments: Word clouds, top questions, and top commenter analytics give a broader look at audience engagement — useful if you want to gauge sentiment, topics of interest, or popular questions. (Views4You)

  • Free to use: Several sources note that Hadzy is free. (30 Days to $100K)

  • Works on many videos: You can try it on any public YouTube video — your own or any other. (Video Ipsum)

⚠️ Limitations & Concerns

  • Ownership and transparency: The domain registration info hides the actual owner’s identity (WHOIS is masked). For some, that raises a caution flag. (ScamAdviser)

  • Traffic and popularity are low: The site ranks relatively low globally, which means it's quite niche. (ScamAdviser)

  • Dependency on YouTube’s API and structure: Several users — particularly around late 2023 — reported that after changes to YouTube’s comment infrastructure, Hadzy (and similar tools) partly broke. For example, one user said:

“YouTube changed something … so that all of these comment finder services no longer work.” (Reddit)
That suggests Hadzy’s reliability can fluctuate when YouTube updates its backend.

  • Limited scope: It doesn’t always handle replies to comments (threads), only top-level comments. (Reddit)

  • Sustainability depends on donations: Since developers mentioned running out of their limited hosting budget, there's a real risk the service could degrade or go offline if support isn’t maintained. (Patreon)

Use Cases — Who Should Use It

If you're a content creator, marketer, or researcher trying to understand audience feedback on YouTube — either of your own videos or competitors’ — Hadzy can be very handy. You don’t have to comb manually through thousands of comments. Instead you can filter by keywords or authors, find recurring questions, see the top contributors, and gauge the main themes quickly.

It's also useful for running contests or giveaways: you can randomly pick a comment, or copy comments easily for reuse.

For researchers or analysts interested in public sentiment, comment patterns, or community behavior around videos, the “statistics”-mode gives a simple aggregated snapshot.

But — consider using it as a support tool, not a primary or guaranteed tool. Because of risks (site downtime, dependency on API, uncertain maintenance), don’t rely solely on Hadzy for critical tasks.

Trustworthiness & Safety

Third-party site-scanners and validators say that Hadzy is likely not a scam. It has a valid SSL certificate, the domain is fairly old (registered in 2014), and there’s no blacklist flags. (ScamAdviser)

On the other hand, the site ranks low in popularity, and the owner identity is masked — which keeps it from earning a “high trust” rating. (ScamAdviser)

If you use it, basic precautions make sense: don’t input sensitive credentials, avoid linking payment info, and treat it like a lightweight utility — not a platform you’d depend on for critical operations.

Key Takeaways

  • Hadzy is a free web tool to search, sort, and analyze YouTube comments — works on any public video.

  • It has features beyond listing comments: filtering, keyword search, comments analytics (word-cloud, top questions, frequent commenters).

  • Created by two developers, originally bootstrapped and not monetized; infrastructure is under budget constraints.

  • Strengths: convenience, speed, useful for researchers/creators. Weaknesses: low popularity, limited scope (may not include replies), reliability depends on YouTube’s API and site maintenance.

  • Based on public safety reviews: probably legit, but treat as a small, independent tool — don’t trust with sensitive info.

FAQ

Is Hadzy free to use?
Yes — according to multiple sources, usage is free. (30 Days to $100K)

Does Hadzy show replies to comments, or only top-level comments?
Based on user reports, Hadzy often fails to properly retrieve replies (nested comments), so it may only reliably fetch top-level comments. (Reddit)

Is Hadzy reliable long-term?
Not necessarily. The creators said hosting infrastructure costs are limited. (Patreon) And because the tool depends on YouTube’s API / comment-system structure, any changes on YouTube’s side can break functionality. (Reddit)

Is Hadzy safe to use?
Third-party security checkers give it a medium-to-good trust score: valid SSL, no blacklist flags, domain age good. (ScamAdviser) But since owner identity is hidden and the site is small, you should avoid giving sensitive data through it.

What kind of users benefit most from Hadzy?
YouTubers and content creators wanting to engage or analyze their audience’s feedback. Digital marketers researching public sentiment on competitor videos. Researchers or analysts wanting to sample or analyze viewer comments and discussion patterns.
