Build your URL Parser with AI in under 5 minutes

Build a URL parser that breaks a URL into its parts — scheme, host, port, path, query parameters, and hash — lets you edit any piece (including the query string), and rebuilds it. Runs in the browser.

What is a url parser?

A URL parser breaks a web address into the pieces it's made of — the scheme, host and port, path, query string, and hash — so you can read or change exactly one of them without hand-editing a long string. It's a constant need for developers: constructing an API request, debugging why a link isn't working, reading what tracking parameters a marketing URL carries, or swapping one value in a query string. The fiddly part is always the query string: every value is percent-encoded, so a space is %20 and an ampersand is %26, and editing it by hand is error-prone. A good parser uses the browser's own URL engine so it matches exactly how the platform interprets the address, lays the query parameters out as an editable table, decodes the values so they're readable, and re-encodes them when it rebuilds the URL — so you can change a parameter and copy a valid result every time.

Common features

Scheme, host, port, path, and hash, each editable
Query string as an editable key/value table
Add, edit, and remove parameters
Percent-decoding for editing, re-encoding on rebuild
Live two-way sync (edit a part or the whole URL)
Assumes https:// for a bare host
Flags malformed URLs instead of mangling them
Uses the browser's real URL engine
Everything client-side; input remembered
Light and dark themes

Real-world examples

Tweaking an API request

A developer pastes an endpoint, changes the page parameter from 2 to 3, and copies the updated URL.

Reading tracking parameters

Someone drops in a marketing link and reads the utm_source and utm_campaign values straight out of the query table.

Fixing an encoded value

A user edits a query value that contained a space, and the rebuilt URL re-encodes it correctly without breaking the link.

Why FloopFloop fits url parser projects

A URL tool is a small utility you want instant, ad-free, and yours. FloopFloop ships the parser you want — a UTM-tag builder, a base64 query decoder, a shareable diff of two URLs, your own styling — on your own domain, with everything parsed by the browser's URL engine and nothing uploaded. The devtools-style 'anatomy inspector' that ships by default colour-codes each part next to an editable query table, and it's one prompt away from being whatever fits your workflow.

Copy any prompt below and paste it into FloopFloop to get started.

Build a URL parser and editor. Paste a URL and break it into colour-coded, editable parts: scheme, host, port, path, and hash, plus the query string as a key/value table where I can add, edit, and remove parameters. Use the browser's URL and URLSearchParams APIs so parsing matches the platform; percent-decode query values for editing and re-encode them when rebuilding. Editing any part should update the URL field live, and editing the URL should re-parse the parts. Assume https:// for a bare host. Keep it deterministic so the first render is hydration-safe, and remember the input in localStorage. 100% client-side.

Create a tool that parses a URL into its components and shows the query parameters as a table I can edit. Keep it in the browser.

Build a query-string editor: paste a URL, tweak the parameters, and copy the new URL. Add a dark theme.

Build a URL inspector that decodes the query string and lets me rebuild the URL after changing parameters.

Frequently asked questions

What parts of a URL does it show?

The scheme (https:), host and optional port, path, the query string as individual key/value parameters, and the hash. Each is shown separately and is editable, so you can see and change exactly the piece you care about.

Can I edit the query parameters?

Yes — they're laid out as a key/value table where you can edit, add, or remove parameters. Values are percent-decoded so they're readable while you edit, and re-encoded automatically when the URL is rebuilt, so you won't accidentally break the encoding.

How does it handle percent-encoding?

A query value like 'hello world' is stored in a URL as 'hello%20world', and an ampersand as '%26'. The parser decodes these for display and editing, then re-encodes when it reassembles the URL — so a space stays a space while you work and becomes a valid escape in the output.

Does it work with a URL that has no scheme?

Yes — if you paste a bare host like 'example.com/path', it assumes https:// so it can still parse. A malformed URL (or a scheme with no host) is flagged rather than mangled.

Is anything uploaded?

No. Parsing uses the browser's own URL engine and runs entirely on your device; your input is saved to localStorage only. The single outbound surface is the /api/health probe.
