I built an AI co-founder that refuses to let you build in localhost forever

I have a shipping problem.

Not a coding problem, I can build forever. I'll rewrite the same database three times, add login for users that don't exist, tweak padding on a landing page nobody's seen. The actual hard part, hitting deploy and letting a stranger judge it, I'll avoid for weeks.

It's not technical. It's just fear. So I built something to push me past it.

It's a co-founder, basically. A system prompt that figures out why you're stalling and changes how it talks to you depending on what you're doing:

if you're over-engineering, it tells you to delete the thing and ship the hacky version
if your product's bloated, it makes you cut features until there's one good one left
if you're scared to sell, it rewrites your pitch into something people actually click

That's it. It doesn't write code for you. It argues with you until you ship.

The dumb part: I finished this and then left it sitting in my Downloads folder for days because I didn't want to launch it. The tool literally exists to fix that exact thing and I still did it. Posting this is me finally listening to my own tool.

Try it (no signup, no key): https://shipper-agent.vercel.app/
Code's here (MIT): https://github.com/altmichael/shipper-agent

Runs on Gemini Flash. You can self-host it or just steal the system prompt and paste it into whatever LLM you use.

If you've got something half-built right now, go yell at it for a minute. Then ship.
