How do I open a .Svelte file?

Drop a .Svelte file onto Analyser at https://lab.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. Open and read programming-language source, build and configuration files as text: C, C++ and their headers, C#, Java, Kotlin, Go, Rust, Python, Ruby, PHP, Swift, Scala, Lua, Perl, R, Dart, Groovy and Visual Basic, GPU shaders (GLSL, HLSL), shell scripts (sh, Bash, Zsh, Fish), and the build and tooling files that fill a source repository - CMake, Makefiles, Ninja, Autotools (.in / .ac / .am / .m4), qmake projects, Doxygen configs and the dotfiles that configure Git, Docker, npm, ESLint, Prettier, Cursor and clang-format. Also opens Objective-C++ (.mm / .hmm), more GPU shaders (.fs / .vs / .gs), Boost.Jam and Meson build scripts, Unix manual pages, web stylesheets (Less, Sass/SCSS) and Svelte components, gettext translations (.po / .pot), Apple entitlements and licence/readme text, plus Cython (.pyx), OpenGL shaders (.fsh / .vsh / .geom), Git hook samples, ESLint and Yarn configs and ASP.NET (.aspx) pages. Each opens with a source preview, line count and metadata, entirely in your browser.

Can I open a .Svelte file online for free?

Yes. Analyser is a free online .Svelte identifier that runs entirely in your browser - your .Svelte file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .Svelte file?

SVELTE is a single-file Svelte component, combining markup, CSS and JavaScript for one piece of a web interface.

Did you know: Svelte, created by Rich Harris in 2016, is a compiler: it turns components into small vanilla-JavaScript bundles at build time, so no framework runtime is shipped to the browser.
A .svelte file holds HTML-like markup, a script block and a style block whose CSS is automatically scoped to that one component.
Because the work happens at compile time, Svelte apps tend to ship less JavaScript than equivalent React or Vue ones.

Depth of analysis: .Svelte is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .Svelte file: Drag a .Svelte file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
