TypeScript compiler online

An online TypeScript compiler for browser-facing code

Check TypeScript errors, refine examples, and run typed browser snippets with HTML and CSS context nearby.

Built for the in-between work

Write TypeScript, JavaScript, HTML, and CSS, preview changes quickly, and export the files when you need them.

01

Compiler feedback where the browser code lives

TypeScript examples often depend on the page around them. TSBin keeps diagnostics, source files, preview output, and console feedback in one workspace.

02

Good for narrowing type errors

Use the compiler page to reduce a problem, test an API shape, or prepare a small example before moving it into docs, a ticket, or an app.

03

Local-first by default

Saved examples stay in the browser unless you export them. That makes the compiler useful for private notes and offline-friendly drafts.

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 check TypeScript errors online?

Yes. TSBin shows TypeScript diagnostics in the editor while keeping the runnable browser preview close by.

13Can I export compiled examples?

You can export the project source files as a zip. The workspace keeps HTML, CSS, JavaScript, TypeScript, and JSON document formats intact.
