I Built 100+ Browser Tools as a Side Project — Here’s What I Learned

A developer's account of growing FroggoTools past 100 browser utilities: why consistency, search visibility, and distribution became harder than building each tool.

For the developer behind FroggoTools, the hard part of running a collection of more than 100 small browser tools was not building each one. It was making them feel like one product and getting people to find them. In a first-person post published September 23, 2026, on DEV Community, Jacob describes how the project grew and what he has learned about consistency, search visibility, and distribution. The figures and observations below are his own account of his project, not an independent audit.

What FroggoTools is

FroggoTools is a side project that collects small browser-based utilities: calculators, converters, date utilities, generators, and formatting tools. Jacob reports that the project has grown to more than 100 pages/tools. In his latest crawl, he counted around 110 HTML pages and reports no broken pages, orphan pages, or duplicate-content issues. That crawl result is his report, not independent validation, and it describes the scope of that one crawl rather than a general standard for sites of this kind.

The product rules he set

Jacob lists the principles he works from:

  • No account is required.
  • A visitor can use a tool immediately.
  • The interface stays simple.
  • Tools work well on mobile.
  • Work is processed in the browser whenever practical.

The last rule is the most specific. He says many calculations, unit conversions, and random-data generation tasks do not need a backend. For those tools, processing in the browser can avoid an API request and keep the visitor's data on the device. He is explicit that not every future tool will necessarily work this way. Treat browser-side processing as a default for suitable simple utilities, not a promise that every tool in the collection runs locally.

Lesson one: a collection is a product problem

Jacob's central observation is short: “Building a percentage calculator is easy.” The difficulty begins with the second task. In his words, “Building calculators, converters, date tools, generators and developer utilities while making all of them feel like they belong to the same product is much harder.”

He lists the recurring concerns that cut across every tool:

  • consistent inputs
  • validation
  • result formatting
  • copy buttons
  • mobile layouts
  • accessibility
  • empty states
  • error handling
  • navigation
  • discoverability

He says he has spent substantial time on this shared experience rather than simply adding more tools. One way to read his account is that each item on that list is a decision to make once and apply everywhere, not something to re-decide for each new calculator. That reading is editorial interpretation; Jacob does not describe a formal system for it.

Lesson two: a technically healthy site is not a visible one

Jacob reports that some tools were getting search impressions while others were barely visible. He also says Google had started testing some date and calculator pages for long-tail searches. He is clear that the domain was still very new, and that a technically healthy site did not put it on page one automatically. In his words: “But technical SEO alone obviously doesn't mean Google suddenly puts a new domain on page one.”

These are his observations from 2026. The post does not include search console exports, exact impression totals, or ranking measurements, so it cannot tell you how large the effect was or how it changed over time.

Lesson three: distribution is the harder job

Jacob says distribution has been harder than building, and calls it “probably the biggest lesson so far.” He lists the work that remains unresolved:

  • sharing the project with people who would use it
  • earning backlinks
  • finding communities that care about these tools
  • learning which tools people actually want
  • choosing what to improve next

What he is doing next

His current priorities follow from those lessons. Rather than adding pages to raise the count, he is focusing on the tools that already have evidence of demand:

  1. Improve tools that already show search impressions.
  2. Add useful tools rather than pages for page count.
  3. Improve discovery between related tools.
  4. Collect user feedback.
  5. Learn more about SEO and distribution.

What the post does and does not establish

The post is a useful record of what Jacob says he built and what he has concluded so far. It is not a benchmark. It does not establish current FroggoTools functionality, its present page count, its analytics, user demand for any specific tool, or how its pages rank. Read it as one developer's account from one project, written in September 2026, and weigh his conclusions accordingly.

He closes by asking readers: “What small browser tool do you keep Googling because you still haven't found one you really like?”
