I'm a solo dev who built 250+ free browser-based tools. Here's what I learned
Every time I needed to compress an image, merge two PDFs, or format some JSON, I ended up on a different site full of popups, signup walls, or upload limits. So I started building my own. That project became Noloii , a free tools hub with 250+ utilities for files, images, calculators, developers, and everyday tasks. No signup, and it runs in the browser. Here's what I've learned building it as a…
One person's journey building over 250 free browser-based tools resulted in Noloii, a tools hub that provides over 250 utilities for various tasks without requiring signups or uploading files. The creator sought a simpler solution to tasks like image compression, PDF merging, JSON formatting, and more, which often involved navigating through intrusive popups, signup walls, or encountering upload limits.
With this goal in mind, Noloii was born as a fully client-side processing web application where files never leave the user's device, thus enhancing privacy and reducing costs.
Throughout the development process, the author discovered several key insights. First, starting with a robust system rather than a collection of standalone tools proved to be more efficient in the long run. Building a shared template and category structure facilitated the creation of additional tools, making the process quicker as the number of tools grew.
Second, privacy played a significant role in user trust. By clearly communicating whether a tool processes files in the browser, users feel safer and are more likely to engage with the service. Providing explanations alongside tools also improved user engagement, as understanding the functionality of a calculator or loan calculator helped users appreciate its value.
Regarding Search Engine Optimization (SEO), the author recognized that SEO for tool sites is inherently slow and that focusing on making each page better than the existing results was more beneficial than chasing quick SEO shortcuts. This approach led to higher-quality content that users find more valuable.
As a solo developer, the author learned the importance of setting boundaries and saying no to unnecessary projects. Prioritizing the polishing of existing tools over building additional mediocre ones led to the successful launch of 250 high-quality tools rather than a larger volume of subpar offerings.
Looking back, the author would recommend several improvements. Implementing analytics and Search Console from the outset would provide valuable insights into user behavior and search performance. Standardizing tool metadata earlier in the process would streamline the overall development and maintenance process. Furthermore, testing on low-end mobile devices would ensure optimal performance across various platforms.
Last but not least, the author highlighted the potential for future enhancements, such as integrating an API, supporting offline functionality, and incorporating AI-assisted features to further enrich the user experience.
If you're interested in exploring Noloii, head over to noloii.com. The author particularly welcomes feedback on the most frequently used tool and any annoyances users encounter with existing options. Suggestions for new utilities that could fill gaps in the current offerings are also appreciated. The author encourages readers to drop comments for further discussion and improvement.
