Runs in your browser: nothing you type is transmitted Needs the server: only the domain or URL you enter is looked up

Why Backserver?

Because half the time you spend on online tools goes to closing ads and worrying about what you just pasted.

Your data goes nowhere

Paste tokens, logs and private config without a second thought: 15 of 19 tools run entirely in the browser, and the rest are clearly labelled.

No sign-up, no ads

No account, no rate limit, no pop-ups. The page loads and the tool is ready.

Find it by what it does

You do not need the exact tool name. Hit Ctrl+K and search for the job instead — HMAC, broadcast or Ingress.

Open source and bilingual

The whole codebase is on GitHub, and the interface was built for right-to-left and left-to-right from the start — not bolted on afterwards.

Frequently asked questions

The things you would want answered before pasting a token into a site you do not know.

01 Is anything I enter stored anywhere?
No. 15 of the 19 tools run entirely in JavaScript inside your browser, so your input never leaves your device. The rest (DNS Lookup, SSL Checker, HTTP Headers) need a network request by their very nature — they are marked “Needs the server” on their card, and even then only the domain or URL you type is processed.
02 Do I need an account?
No. No sign-up, no usage limits, no ads. Open the tool and start.
03 What is the fastest way to reach a tool?
Press Ctrl + K ( + K on a Mac) anywhere on the site to open the command palette. Type a tool name or just a capability — HMAC, Ingress, VLSM. Move with the arrow keys and open with Enter.
04 Can I suggest a new tool?
Yes. The project is open source — open an issue on the GitHub repository to request a tool or report a bug.
