Originally founded as a project to simplify sharing code, GitHub has grown into an application used by over a million people to store over two million code repositories, making GitHub the largest code host in the world.

Format JSON, generate passwords, convert colors, merge PDFs โ€” 122 utilities that run entirely in your browser. No accounts, no uploads, your inputs never leave the page.

Mello is a directory of 122 utility tools that all run entirely in your browser. Format JSON, generate passwords, convert colors, merge PDFs, resize images, decode JWTs, calculate loans โ€” every tool runs as client-side JavaScript, with no server-side processing at any step.

The design rule is simple: no uploads, no accounts, your inputs never leave the page. That makes Mello safe for the everyday moments where you'd otherwise paste sensitive data into a free online tool โ€” a JWT containing a real session, a scanned passport, a photo with embedded GPS coordinates, a production database export. The catalog spans developer utilities, finance calculators, image and PDF tools, design generators, text utilities, password generation, hashing, and more. Free, no signup, no paid tier.

GitHub features and specs

  • collaboration
    GitHub provides a platform for multiple developers to work on the same project concurrently, facilitating collaboration through features like pull requests, code reviews, and issues tracking.
  • integration
    GitHub integrates seamlessly with various third-party tools and services, such as CI/CD pipelines, project management tools, and many development environments, enhancing productivity and workflow efficiency.
  • version_control
    Utilizes Git for version control, allowing users to track changes, revert to previous versions if necessary, and manage different branches of development, ensuring code stability and history tracking.
  • community
    With millions of developers and a vast repository of open-source projects, GitHub fosters a robust community where users can contribute to projects, seek help, share knowledge, and collaborate broadly.
  • availability
    GitHub is a cloud-based platform, which means that projects are accessible from anywhere with an internet connection, providing flexibility and convenience to developers globally.
  • documentation
    GitHub allows for comprehensive project documentation through README files, wikis, and GitHub Pages, making it easier for users to understand project context and contribute effectively.

Possible disadvantages of GitHub

  • cost
    While GitHub offers free plans, more advanced features and private repositories come at a cost, which might be a barrier for some individuals or small teams.
  • steep_learning_curve
    For newcomers, especially those unfamiliar with Git, the learning curve can be quite steep, making it challenging to utilize all of GitHub's features effectively.
  • privacy_concerns
    Given its expansive, open nature, users must be cautious with sensitive or proprietary information. Even with private repositories, there is a latent concern over data privacy and security.
  • interface_complexity
    The user interface, while powerful, can be overwhelming and complex for beginners or those not deeply familiar with version control concepts.
  • performance_issues
    Occasionally, GitHub may experience downtime or performance issues, which can disrupt workflow and prevent access to repositories temporarily.
  • limited_storage
    GitHub imposes limitations on storage space and file size within repositories, which can be restrictive for projects requiring large datasets or binaries.

Questions & Answers

As answered by people managing GitHub and Mello.tools.

Why should a person choose your product over its competitors?

Mello.tools's answer:

Most "free online tool" sites send your input to a server you don't operate. For utilities you reach for daily โ€” JWT decoders, image compressors, PDF mergers, password generators โ€” that means handing potentially sensitive data to a third party you have no agreement with. Mello solves this architecturally: the site is statically generated, there are no API routes, and the only thing the server returns is HTML and JavaScript. If your input matters at all, that's the difference.

How would you describe the primary audience of your product?

Mello.tools's answer:

Developers, designers, small-business operators, and knowledge workers โ€” anyone who reaches for a "free online tool" several times a week. The privacy-first design especially fits people working with sensitive material (auth tokens, scanned IDs, financial data, unannounced creative assets) and people on slow or metered connections where avoiding uploads matters in practice.

What's the story behind your product?

Mello.tools's answer:

Mello started from a recurring annoyance: needing to do something quick โ€” decode a JWT, compress a photo, format a JSON payload โ€” and realizing the easiest path was to paste sensitive data into a free site I had no relationship with. The "decoded client-side" claims in small text were untestable from outside. Browser-only seemed like the obvious right answer for these kinds of utilities, so I built it that way from the start. Mello shipped in May 2026 with 122 tools across 10 categories.

Which are the primary technologies used for building your product?

Mello.tools's answer:

Next.js 15 (App Router) with full static export, React 19, TypeScript, and Tailwind CSS v4. Tool implementations use native browser APIs (Canvas, Web Crypto, FileReader, DOMParser) where possible, with carefully chosen JS libraries for the rest: pdf-lib and pdf.js for PDF handling, libheif compiled to WebAssembly for HEIC decoding, exifr for image metadata, marked and turndown for Markdown conversion, sql-formatter for SQL. Hosted on Cloudflare Pages as a fully static site.

What makes your product unique?

Mello.tools's answer:

Mello is the only utility-tools directory at this scale built around a strict no-server-processing rule. Every one of its 122 tools runs as JavaScript in your browser โ€” no uploads, no accounts, your inputs never leave the page. JWTs, photos with embedded GPS coordinates, contract PDFs, production data: none of it ever leaves your machine, because there is no server endpoint that could see it.

The Top 10 GitHub Alternatives
However, like any (human) product, the platform has its limits, downsides, and critics.

Another criticism concerns the price tag: some users have pointed out that GitHubโ€™s pricing model is too inflexible. Moreover, some...

    This is why the gate needs a trace it can trust, and why AgentLens is the other half of this workflow. agent-eval scores and gates the output; AgentLens captures the trace of how the agent got there โ€” every model call and tool step, the resolved inputs (not the templated ones), the raw outputs.
