Maker here. I built MockBolt because every new frontend project started with the same setup work: spin up json-server, create fake data, open a local port, and only then start building the actual UI.
MockBolt removes that setup time. Paste JSON, click generate, and get a live API URL immediately. No signup, no email, no account.
I would especially love feedback on two things:
1. Is the public URL plus secret management URL flow clear?
2. What feature would make this a daily tool for you instead of a one-off utility?
