DevStack is a free tool directory. This page explains what stays in your browser, what a tool sends to finish a job, and what the donation list publishes.

The short version

You can open every tool without telling DevStack who you are.

There is no sign-up, no profile, and no inbox of past jobs. A tool runs when you give it an input, then it returns a result on that page.

Some jobs finish in the browser. Others send the file, text, numbers, or public URL you submitted to the DevStack API so the result can be built and sent back.

No account is created when you visit or use a tool.
DevStack does not sell a browsing profile.
Do not submit secrets or files you are not allowed to process.

What stays on this device

A few preferences never leave the browser unless you submit them yourself.

Tools you bookmark are stored in localStorage on this device, under a list of tool ids. The JSON and SQL formatters can also keep the draft you were editing so it is still there when you come back.

That storage is not a DevStack account. Another browser, or this browser after you clear site data, will not have those saved tools or drafts.

Saved tools are ids only, not your files.
Formatter drafts stay in localStorage until you clear them.
Clearing site data for DevStack removes both.

What a tool sends

If a tool needs the server, it sends the input for that job and returns the output.

Image, document, formatting, calculation, and security tools that cannot finish locally post the file or text you chose. The API uses that input to produce the download, the formatted text, or the numbers on the page.

These tools are not a gallery and they are not a place to store files. Treat every upload as something you are handing to the service for that request. Passwords, private keys, customer lists, and documents you cannot share do not belong in a tool.

The input is the file, text, or numbers you submit.
The output comes back to the page you have open.
There is no library of your previous uploads to browse later.

Website screenshots

A screenshot is made by opening the public address you type.

Website to Screenshot loads that http or https page, waits for the layout, and saves a PNG or JPEG. You choose a desktop, laptop, or mobile viewport, and either the first screen or the full page up to the capture limit.

Local and private addresses are refused. That includes localhost, link-local hosts, and private network ranges. The tool is for public pages you are allowed to open.

Only a public http or https URL is accepted.
Private and local hosts are blocked.
The image is returned to you. It is not added to a public gallery.

The donation list

A donation you add is stored so other people can see who supported the studio.

The form asks for a name, an amount in rupiah, and an optional note. You can show the name as Anonymous. The date is stored with the entry. The list, the donor count, and the recorded total are visible on the Donate page.

The form does not charge a card and it does not collect a payment account. It records the supporter details you chose to publish.

Name or Anonymous, amount, note, and date are stored.
The list is public on the Donate page.
No card number is collected.
