About
One behaviour, done properly.
Terminal3 exists for a single moment: something broke, you're away from your development environment, and you need to understand it now.
What it does
You paste what broke — a stack trace, an HTTP response, a log excerpt, a deployment error. Terminal3 works through it in three passes. Diagnose explains what most likely happened and why. Fix gives you an ordered remediation path with the commands that go with it. Verify tells you how to confirm the problem is actually gone rather than temporarily quiet.
That's the whole product. There is no dashboard, no integration marketplace, and no agent sitting inside your cluster.
What it deliberately isn't
Terminal3 is not a remote shell. It has no connection to your servers, repositories, logs, deployments or monitoring, and it never executes anything on your infrastructure. Commands are handed to you to run, with a warning attached when they're destructive.
Everything it concludes comes from the text you paste. That's a real constraint, and it's why every analysis carries a confidence score and a list of alternative explanations instead of a single confident answer. A well-known error signature earns high confidence. An ambiguous log doesn't, and Terminal3 says so.
Why mobile
The desktop version of this problem is already well served — you have your editor, your terminal, your logs and your search history. None of that is true at 11pm on a train. Terminal3 is designed for the second case, which is why the app runs on your phone and this site is what you get on a laptop.
Where it is today
Terminal3 is version 1.0.0, in beta. Saved incidents and runbooks are stored locally in your browser — there is no account and nothing syncs between devices. If an AI provider isn't configured, the app runs in Demo Mode: the six bundled sample incidents work end to end, and arbitrary input is refused rather than answered with a guess.
Who built it
Terminal3 is built by Manoj Paliwal. It started from a narrow, familiar problem, and the intent is to keep it narrow.
Feedback — especially an analysis that got it wrong — is genuinely useful: hello@terminal3.fun.
