Build an HTTP URL from explicit structured parts

Assemble a credential-free HTTP or HTTPS URL from reviewed JSON fields and ordered query tuples.

Local processingNo sign-upNo fetch or upload

Build URL

URL text stays in this tab. Nothing is opened or checked online.

Tool Swim does not upload, fetch, save, log, or create presets from these values.

Built URL and component proof

Results are inert text or JSON with the applied interpretation visible.

What this tool proves

Explicit URL interpretation

The builder accepts only HTTP or HTTPS and deliberately has no username or password field. Unicode hostnames are serialized to their ASCII form.

Structured fields prevent delimiter guessing

The builder accepts only HTTP or HTTPS and deliberately has no username or password field. Unicode hostnames are serialized to their ASCII form.

The output includes the built URL, parsed parts, retained query order, and whether a supplied default port was omitted by standard serialization.

Private, bounded URL processing

The operation runs only after you choose it. Input stays in the current browser tab: Tool Swim does not fetch a destination, resolve DNS, test reachability, upload content, save an account preset, or invoke the developer API.

URLs are capped at 8 KiB, query text at 256 KiB, component text at 64 KiB, query lists at 2,000 pairs, each query name or value at 8 KiB, and serialized output at 1 MiB.
