Show HN: Text alerts when Codex resets are announced

Hacker News - Tue, 09/29/2026 - 12:52pm

I built this out of my usage limit frustration in Codex.

OpenAI had started announcing more resets (which helped), but I often didn't see them until my usage had already refilled to 100%.

I wanted to know ASAP so I could burn through remaining usage before the reset.

So I built this text alert service that monitors X and sends text updates when a new Codex reset is announced.

It currently sends SMS alerts to users in the US and Canada, and Telegram alerts otherwise.

The service has been useful for me - would love any feedback or beta testers on Reset Alerts.
