My app is not in Rails. It is React and Supabase.
Most of them are. The diagnostic tells you honestly whether the app is worth repairing where it stands or worth rebuilding in Rails, and roughly what each path costs. Sometimes the answer is that you should keep what you have and fix three specific things. You get that answer in writing either way.
Can anything real be built in five days?
A working prototype, yes: real data, real accounts, deployed where people can use it. A hardened product serving thousands of paying customers, no, and anyone promising that in a week is selling you a template. Five days gets you something true enough to show investors, test on customers, or hand to a developer. What comes after that is a different conversation with a different price.
You are one person. What happens if you get hit by a bus?
This is the right question to ask any solo shop. The answer is the handoff package: your repo, your infrastructure, standard Rails, a written runbook, and a recorded walkthrough. It is built so that the next developer can pick it up without me. That is not a promise, it is a deliverable you can inspect on day five.
Why does the diagnostic cost money?
Because it takes a day of real work and produces something useful on its own: a written assessment of what you have, what is broken, what it would take to fix, and what it would cost. If you go ahead with a run, the fee comes off the price. If I tell you that you do not need me, you get it back.
Can I just keep prompting until it works?
Sometimes, and if that is working you should keep going. It tends to stop working at the point where the problem is structural rather than local: the data model is wrong, the auth is wrong, the thing that breaks is not in the file the model is looking at. If you have been circling the same bug for two weeks, that is the signal.
What does it cost after the run?
Nothing, if you want. Take the repo and go. If you want the app kept alive without hiring, the Roundhouse is $1,497 a month and you can cancel any month. Larger builds after a prototype get quoted separately, fixed price, same as everything else.
