More than a compiler text box
TSBin gives TypeScript examples a browser page, stylesheet, and preview area, so snippets can exercise real DOM behavior instead of isolated functions only.
TypeScript playground
A TypeScript playground for real browser snippets
Use TSBin to test TypeScript alongside HTML, CSS, and browser APIs. Write code in a focused workspace and preview the result immediately.
Built for the in-between work
Write TypeScript, JavaScript, HTML, and CSS, preview changes quickly, and export the files when you need them.
Quick feedback while working
The editor is useful for narrowing down TypeScript errors, building minimal reproductions, and sharing the shape of a browser-side implementation.
A small lightweight workspace
You get a practical project surface without bringing in a full framework or package install step.
What TSBin gives you
Concrete browser-editor features, not a social feed or a heavy project scaffold.

Frequently Asked Questions
1Is my code saved anywhere?
Your projects are saved in your browser's local IndexedDB storage once you save or run them. Existing saved projects autosave after edits, and TSBin does not upload your code to an account.
2Do you have plugins?
Emmet support is available today for HTML and CSS editing. More editor helpers are planned.
3Do you have Markdown support?
Markdown support is coming soon. Today, TSBin supports HTML, CSS, JavaScript, TypeScript, and JSON project files.
4Can I keep working offline?
Yes. TSBin is designed around local-first browser storage, so saved projects can reopen without account setup or a server round trip.
5What file formats can I save or export?
TSBin supports HTML, CSS, JavaScript, TypeScript, and JSON project files. Export keeps those document formats in a zip file.
6Can I download my code?
Yes. Use File > Export Project to download the current workspace as a zip file.
7How can I clear the console?
Type clear() in the console and press Enter. The shorter clear command also clears the console.
8Does TSBin support dark mode and light mode?
Yes. Use the theme button or Settings to switch themes, or press ModShiftS to toggle between light and dark mode.
9Does TSBin support keyboard shortcuts?
Yes. Open the keyboard shortcuts dialog from the header or press Mod/ to see the available shortcuts.
10Do I have to create an account?
No. There is no account setup, and TSBin does not create an account for you automatically.
11How do I request features or report bugs?
Open the File menu and choose Send Feedback. The form supports bug reports, feature requests, and privacy requests.
12Can I preview browser output from TypeScript?
Yes. TSBin compiles TypeScript for browser execution and shows the result in the preview pane.
13Is this only for TypeScript?
No. The playground also supports HTML, CSS, and JavaScript, which makes it useful for complete front-end snippets.
