profile-technology-icons turns a GitHub profile into a technology list

It is a list first and a generator second

The project describes itself as a list of icons that can be used during GitHub profile creation to show what technologies and languages are known, and contributions are invited. The generator is the friendly face of it, an online page at the project's GitHub Pages site, but the substance of the repository is the `icons/` directory and the tables in the README that map each technology to a file. Each row gives the icon, the technology name and the raw URL, so you can copy the URL directly. The approach matters for how the result looks on a profile page, because the icons are loaded from raw.githubusercontent.com rather than from a repository you would have to clone or commit, which keeps a profile README to a few kilobytes of markdown instead of a few hundred of binary files.

The catalogue is organised by domain, and the domains are the point

The table of contents is a list of about thirty sections, and reading it tells you what a working developer profile is expected to show. There is communication with HTTP, WebSocket, gRPC, GraphQL, REST, SOAP, tRPC and SSH, then version control with Git, GitHub, GitLab, Bitbucket and Codeberg. Then tools, web development, UI and UX, and a per-language section for JavaScript, Java, C and C++, C#, Lua, typesetting languages, Python, PHP, Ruby, Zig, Rust, Fortran, Go, Erlang and Elixir, and Apache. The rest are infrastructure categories: mobile development, databases, bibliography managers, DevOps, cloud, AI, analytics, testing, game development, operating systems, microcontrollers, MQTT technologies, blockchain and geospatial. The categories make the tool more than a logo grab bag, because they are a checklist you can run your own stack against.

The generator is a Gatsby site with a drag and drop picker

The generator is a Gatsby site, and the manifest shows what it is built from. Gatsby 5 is the framework, React 19 and React DOM 19 with styled-components 6 for the styling, and the Material UI packages for icons and components, with a plugin for Material UI integration and another for styled components. The picker uses the dnd-kit packages, the core, the sortable addon and the utilities, which is how you reorder the icons you have picked. The output pane uses CodeMirror with a Darcula theme, so you can read and edit the generated markdown before you copy it, and there is a copy to clipboard component for the same reason. The plugin set also includes a manifest plugin, a smooth scroll plugin and gatsby-link, and the deploy script builds with a path prefix and pushes to gh-pages, which is how the site ends up at a project URL rather than a user one.

A pnpm project with a strict toolchain

The project pins its tooling tightly, which is a reasonable stance for a site with this many dependencies. The package manager is pnpm at version 9.15.9, and there is both an `engineStrict` flag and an `engines` block requiring exactly that pnpm version, so an install with a different package manager or a different pnpm fails rather than producing a subtly different tree. A `preinstall` script runs `npx only-allow pnpm`, which is what makes the strictness work, since it stops an npm install before it starts. The scripts cover the Gatsby lifecycle, with develop and start both running the dev server, build and buildProd for the two path modes, serve, clean, and a deploy that builds with the prefix and publishes to gh-pages. Dependency updates are handled by renovate, with the configuration at the root.

The trademark note and the alternative for badge users

Two details in the README are worth reading before you publish anything. The first is the trademark paragraph, which says that all product names, logos and brands are the property of their respective owners, that the names are used for identification purposes only, and that use does not imply endorsement. That is the standard position for a logo list, but it means the icons carry some risk that using a wordmark in a profile does not. The second is the related work note, which says that if you prefer badges rather than icons you should look at a different project, Badges4-README.md-Profile. So the two approaches are explicitly distinguished rather than folded together, and picking the icon path means accepting the visual style of a row of logos rather than a row of shields.

Where the project sits

The repository is a small static site project rather than a library. The top level holds the `icons/` directory, the `src/` directory with the Gatsby source, a `static/` directory for the demo animation and other assets, a `gatsby-config.js` and a `gatsby-browser.js`, a `.gitpod.yml` and a `.gitpod.Dockerfile` for a cloud development environment, a `renovate.json`, and an `.npmrc`. The licence is not identified in the repository metadata, and there are no GitHub releases, since the content that matters is the icon set and the site is deployed continuously. The last push to the main branch was on 2026-10-14, and the demo animation in the README shows the picker in use, so the interactive behaviour is the quickest way to understand what the project does before you install anything.

Editorial conclusion

Adopt profile-technology-icons if you want a GitHub profile README that lists your stack as logos rather than as text, since the generator handles the markdown and the raw file URLs are stable. Do not adopt it if you need badges rather than icons, because the project points to a separate repository for that. Verify first that the icons you want are present in the catalogue, since the domain list is long but not exhaustive, and check the trademark note, since the icons are the property of their respective owners and are used for identification only.
