Mock This API Response

Building something and need fake-but-realistic data? Describe the shape — get a clean sample dataset with believable values and the edge cases to test.

Describe what you want to match in plain words. Get the regex, every piece explained, and test cases — so you actually trust it before you ship it.

Say what you want in plain English, get clean SQL back — plus the gotchas (nulls, dupes, slow joins) you'd only find in production at 2am.

Designing an API and want it to not be a regret in six months? Describe what it does — get clean endpoints, naming, and the edge cases you'd forget.

Naming things is half of programming and you're stuck. Paste the code or describe it — get clear, consistent names that make the code read itself.

Paste the stack trace that means nothing to you. Get what actually broke, why, and the most likely fix — in plain English.

The thing every dev skips. Tell it what your project does — get a README people can actually follow: what it is, how to run it, and why it exists.

Your query's slow and the EXPLAIN output is gibberish. Paste it — get what's actually happening, the bottleneck, and the index or rewrite that fixes it.

Find the holes before someone else does. Paste your code — it runs an OWASP-style security review and tells you what an attacker would try first.

Porting code to a new language or framework? Paste it — get the converted version plus the traps that don't translate one-to-one.

"Works on my machine" — famous last words. Describe your app — get a Dockerfile and setup that runs the same everywhere, explained so you understand it.

Stop deploying by hand and praying. Tell it your stack and host — get a CI/CD setup that tests and ships automatically, with the config and the why.

It works but it's slow. Paste it — get where the real bottleneck is, the optimized version, and whether the speed-up is even worth the complexity.

Paste the function you're embarrassed by. Get it cleaner and readable with the exact same behavior — plus a note on what was wrong so you stop doing it.

Get the data model right before it bites you. Describe your app — get tables, relationships, keys, and the design choices you'd regret skipping.

Don't pick a stack you'll fight for years. Describe what you're building and your skills — get a real recommendation with trade-offs, not hype.

Practice coding interviews the right way. Paste the problem — it nudges you toward the solution with hints, only revealing the answer once you've actually tried.

That boring task you do by hand every week. Describe it — get a script to automate it, with setup steps simple enough that a non-coder can run it.

You know you should. Paste the function — get the test cases that actually catch bugs, including the edge cases you'd forget at 6pm.

Dropped into unfamiliar code? Paste it. Get the map — what it does, how it flows, and where the bodies are buried — before you touch a thing.

Stuck? Explain the problem to it out loud. It asks the questions that make you find your own bug — and only steps in when you're truly stuck.

Got dropped into a framework you've never used? Name it and what you know — get the mental model, the core concepts, and the 20% you need to be productive today.

"fixed stuff" is not a commit message. Paste your diff or describe the change — get a clear commit message your future team will actually thank you for.

Shipped an update? Don't bury it in 'various bug fixes.' List what changed — get release notes / a changelog that's clear, scannable, and makes users care.
