How it works

Save and reopen the browser copy of your HTML file

The editor is served online; your working project is stored locally by the browser.

You can reach the HCODX editor from a laptop or Chromebook without installing a desktop IDE. Once you work on a project, the browser keeps its local copy. That is why reopening the same site in the same profile can restore your work without a login. It is also why opening it on a phone, a guest profile or a second computer does not show the first device’s files.

Browser data is not permanent storage. Clearing site data, using private browsing, changing profiles, or losing the device can make that copy unavailable. Export an important project as a ZIP and store the archive somewhere you control. Do not treat “it was still there yesterday” as a backup strategy.

Access

Use a modern browser instead of installing a local editor application.

Persistence

Project data is associated with this site and the current browser profile.

Portability

A ZIP export is a file you can keep, share or open in another development environment.

Repeatable workflow

Create, return, export

A browser workspace is most dependable when you know where the working copy ends and the backup begins.

Open the editor Create or select a project and give the files clear names. Use separate HTML, CSS and JavaScript files when the work needs them.
Return in the same profile Reopen the editor in the browser profile where the work was saved. Verify the project and recent changes before relying on them.
Export a checkpoint Download a ZIP when the work matters, before resetting the browser or changing devices.
Reopen elsewhere Move the exported files into your chosen editor or host. Test paths and assets again because a different environment may resolve them differently.

If you need real-time collaboration or automatic cross-device synchronization, use a service designed for that purpose. Local browser storage does not provide either.

Make the choice deliberately

Browser workspace, desktop IDE and cloud IDE

Each solves a different constraint; “online” is not automatically better for every project.

Compare

HCODX browser workspace

Fast start for front-end files with live browser preview. Projects are local to this browser profile; export for a portable copy.

Compare

Desktop IDE

Direct access to local files, command-line tools, build systems and larger repositories. Setup and device access are your responsibility.

Compare

Cloud IDE

May provide hosted environments, accounts and device sync. Check its storage, privacy, cost and network requirements before using it.

A migration drill

Move the project to a second machine without guessing

A deliberate transfer is more reliable than expecting browser-local files to follow you.

01

Freeze a known version

Make a visible final change—such as a version note in the page—then export a new ZIP. This helps distinguish the latest archive from an older one.

02

Inspect the archive before leaving

Unpack it and check the expected HTML, CSS, JavaScript and assets. If a file is missing, correct the project and export again while the original browser still has the working copy.

03

Move the ZIP through a channel you trust

Use removable storage or your chosen file-transfer service. A project in HCODX’s browser storage does not transfer merely because you open the website on the new machine.

04

Test on the destination

Open the files in the target editor or host. Confirm relative links and browser behavior there, then keep the archive as a recovery point.

Do not clear the original browser’s site data until you have verified the transferred files.

Which copy is which?

The workspace, preview and ZIP are three different places

Knowing which copy you are looking at prevents a common migration mistake: assuming a preview or download automatically updates the browser project.

Compare

Working project in hcodx.io

The editor keeps project files in browser-local storage associated with your current profile and the HCODX site. IndexedDB is the primary store, with localStorage used as a fallback during initialization or if IndexedDB is unavailable.

Compare

Rendered preview

The preview receives an assembled document in a separate frame. It shows how the current front end runs, but it is not your project store or an independent backup.

Compare

Downloaded ZIP

The archive is a snapshot of files at export time. Later edits in the browser do not silently update an earlier ZIP, so export again after an important revision.

Before you close the tab

A five-minute reliability check

It is easier to discover a storage assumption while the project is still open.

01

Name your files clearly

Names such as index.html and css/site.css make exported structure easier to understand later.

02

Confirm the preview

Check that relative links and scripts load in the browser frame, not just in the source editor.

03

Export a ZIP

Keep a separate copy before browser cleanup, device migration or a major rewrite.

04

Test the archive

Open the downloaded files and confirm that the expected assets were included.

Practical answers

Browser workspace questions

The most important questions concern where the work lives.

No automatic cross-device sync is provided by browser-local project storage. Export the project and move the files yourself.

That can remove the browser-stored copy associated with the site, whether it is in IndexedDB or localStorage. Export important work before clearing data or using a temporary browser profile.

Yes. The ZIP contains ordinary project files. Open them in another editor or deploy them to a compatible static host, then verify paths and behavior there.

No. Tabs in the same browser profile generally share site storage, while another device or profile has a different store. Avoid editing the same project in two tabs simultaneously unless you have confirmed how changes are reconciled.

That is risky. Private sessions commonly discard site storage when their windows close. Export the project before ending the session if you need it later.

It provides source files, not a deployment test. Check asset paths, network requests and any server assumptions on the actual hosting origin.
