Quick UUID Generator vs SendMan

Sometimes you just need one identifier, right now, on the phone in your hand. Not a code snippet, not a terminal, not a website you have to trust with it. Open the app and the identifier is already there. Tap it and it is on your clipboard. WHICH VERSION YOU GET, AND WHEN IT MATTERS Quick UUID generates four kinds, and the difference is worth knowing before you paste one into a database. • v4 is pure randomness. The default, and the right choice when you need something unique and have no reason to care about order. • v7 carries the time it was made in its leading bits, so v7 identifiers sort in the order they were created. That is what makes it pleasant as a database primary key: new rows land next to each other instead of scattering across the index. • v1 also encodes a timestamp, alongside a random node value: nothing about the device is embedded in it. Older systems expect this one. • v5 is the odd one out, because it is not random at all. You give it a name and a namespace, and the same name always produces the same identifier. Generate it today or next year, on this phone or another one, and the value is identical. The namespace is chosen with the built-in DNS, URL, OID and X.500 selector. UPPERCASE OR LOWERCASE One tap switches the output between cases. Some systems insist on uppercase, others on lowercase, and retyping a 36-character string by hand is how mistakes happen. EVERYTHING YOU GENERATED IS STILL THERE The full history stays on the device, with the version and the time next to every value. Tap any entry to copy it again. Useful when you generated three identifiers in a row and now need the second one back. WORKS WITH NO NETWORK Everything happens on the phone. No account, no sign-in, no registration: the identifiers are created on the device and never leave it, so the app keeps working on a plane, inside a locked-down office network, or in airplane mode. WHAT IT DOES NOT DO It generates identifiers. It does not validate or decode ones you received from somewhere else, and it does not export batches to a file.

SendMan is a full-featured API client for iPhone and iPad — build, send, and test HTTP requests anywhere, without opening your laptop. Debug a REST endpoint on the train, test a GraphQL query between meetings, or inspect a live WebSocket: SendMan puts a complete API testing toolkit in your pocket. Built natively for iOS, it's fast, works offline, and is made for developers, QA engineers, and mobile teams who need real API tooling on the go. BUILD & SEND REQUESTS - Full HTTP request builder — GET, POST, PUT, PATCH, DELETE & more - Add headers, query params, and request bodies in seconds - Reuse {{environment}} variables across URL, headers, params & body - Write tests and validate responses automatically - Generate ready-to-use code from any request ORGANIZE YOUR WORK - Save and group requests into Collections - Switch between multiple Environments and configurations - Full request History with status codes and response times - Instant search across everything GO BEYOND REST - GraphQL — run queries, mutations, and subscriptions - WebSocket — test real-time connections live - Traffic Capture — intercept and inspect HTTP/HTTPS traffic in real time - Monitor — run requests on a schedule and watch performance DEVELOPER TOOLS - Mock Data — auto-generate realistic JSON to test your APIs - JSON Diff — compare two responses and spot every change instantly - Dashboard with success, failure, and average response-time metrics - Response insights, charts, and performance tracking FULL REQUEST CONTROL - Fine-tune timeouts, max response size, and HTTP version - Toggle SSL certificate verification for self-signed certs - SSL/TLS key logging for deep debugging - Light & dark themes plus custom color palettes PRIVATE BY DESIGN Your requests, history, and data stay on your device. SendMan works offline and never sits between you and your APIs.
