Show HN: Ottr – one-click human approval links for scripts, CI, and AI agents (opens in new tab)

Automations, CI jobs, and AI agents often need a human “yes” at the last step. Most solutions require bots, dashboards, or auth flows that feel heavier than the problem.

I built Ottr to make this a primitive.

Ottr gives you a signed, expiring approval link you can generate from any script. When the link is clicked, the process continues. No accounts. No UI.

Flow:

• Script or agent requests approval → gets a one-time URL

• URL is sent to a human (email, Slack, SMS, etc.)

• Human clicks → script resumes (via polling)

This is early and deliberately minimal. I’m trying to validate whether “approval links” are a useful building block, or if people already solve this in a better way.
