SEO by Daniel vs Apache Nutch

Apache Nutch is an open-source web crawler framework built on Hadoop. You configure it, run it, and it indexes crawled pages into Solr or Elasticsearch. SEO by Daniel is a hosted audit that takes one URL and returns a client-ready report. Nutch is infrastructure you assemble. SEO by Daniel is a product you use. They only look similar from a distance.

Where Apache Nutch wins

• It is free and open source. No licence, no per-crawl fee, and you can read every line.
• It scales. Hadoop is built for crawls that do not fit on one machine, so Nutch handles corpora far larger than an SEO crawl.
• It plugs into a search stack. Solr and Elasticsearch integration means the crawl output already serves a search or data pipeline.
• You own the data. The crawl lives in your infrastructure, which matters for archives and regulated data.
• Full control. Fetch schedules, parsers and scoring are yours to tune. Nothing is hidden behind a hosted product.

Where SEO by Daniel wins

• No engineering to get an answer. One URL gives a 0-100 homepage score in about two seconds. Nutch needs a cluster and a config before it fetches anything.
• SEO logic is included. Nutch crawls pages. It does not know a missing title from a duplicate meta description. Say what you want to check, and the audit checks it.
• Sitemap auto-discovery. We read robots.txt, follow nested sitemap indexes and handle gzipped sitemaps. Nutch crawls from seeds you supply.
• A client-ready deliverable. Executive summary, issues grouped by severity and CSV export. Nutch gives you records in an index you still have to turn into a report.
• €19/month against your time. Nutch is free, but the spider, the scoring rules and the reporting layer are work you pay for in engineering hours.

A real example

You are a backend engineer at a startup. A product manager asks you to "crawl the site and check the SEO", because you are the person who writes crawlers. You could stand up Nutch, wire it to Solr, write parsers for titles and meta tags, decide which findings count as severe, and build a page to show the results. That is a project, and none of it is the product manager's actual question.

You scope it and realise the SEO audit part is maybe ten percent of the work and all of the deadline. Nutch is still the right call if the company wants a search index over its own content, or a crawler for a data pipeline nobody sells. For the audit, it is a detour.

So run SEO by Daniel on the domain first. The score and severity-grouped issues answer the product manager in two seconds, and you can hand the CSV to marketing. If the search-index project is real, build it on Nutch and keep the two jobs separate. The engineer who can do both should not do the easy one the hard way.

The verdict

| | Apache Nutch | SEO by Daniel | |---|---|---| | Best for | Building large crawls and search pipelines | Whole-site scored SEO reports | | Delivered as | Engineering framework | One URL, no account | | SEO logic | None, you build it | Built-in scoring | | Client-ready report | No | Executive summary, severity grouping, CSV | | Sitemap discovery | Seeds you provide | Automatic | | Setup | Cluster and configuration | None | | Price | Free open source | €19/mo entry |

When to pick which

Pick Apache Nutch when you are an engineer building a crawler for a corpus, an archive or a search index, and you want to own the pipeline. It is the wrong tool for a client audit, but the right one for a crawl that has to live inside your own stack.

Pick SEO by Daniel when the job is a scored site audit with a report at the end. There is nothing to install, no cluster to keep alive, and no parser to write. If a client is waiting on the answer, this is the shorter path.

FAQ

Is Nutch hard to run? Nutch normally runs with Hadoop, so it is a real infrastructure task. SEO by Daniel runs in a browser from one URL.

Is SEO by Daniel free like Nutch? The quick scan is free and needs no account. Full-site audits and monitoring start at €19/month. Nutch is free software, but it costs engineering time.
