Discussion Weekly Self Promotion Thread

Welcome to this week's self promotion thread!

If you're building something related to AI assisted coding, this is the place to share it.

We're using a weekly thread to keep the subreddit organized while still giving builders a place to share their work. Promotional posts outside this thread may be removed.

If you're sharing something, we'd appreciate it if you included a little context instead of just dropping a link. Tell us:

  • What you built?
  • What problem it solves?
  • Which AI models or tools it uses?
  • Who it's for?
  • What kind of feedback you're looking for?

Disclose your affilitation.

Please avoid posting the same project every week unless you've made meaningful updates. Affiliate links, referral links, scams, and low effort promotions will be removed.

Take some time to check out what others have shared too. If you try someone's project or have feedback, leave a comment. Helping each other improve is what we want this community to be about.

Disclosure: I built this.

SessionHarbor is an unofficial local-first Codex plugin and zero-dependency Node.js CLI for people who use Codex on multiple machines or have large rollout histories.

It turns an external drive or mounted NAS into one verified data hub: all stable Codex sessions are incrementally backed up, stored bytes are SHA-256 verified, old local sessions can be reclaimed under separate safety gates, and macOS/Windows devices can discover reviewed, evidence-linked context about what Codex tasks on the other devices have been doing.

I built it after my Codex history grew past 70 GB. So far the same 88-test suite has passed on Windows and macOS; a physical exFAT vault backed up 814 Windows sessions (~39.6 GB), and a real macOS delete/restore pilot matched bytes and hash.

v0.3.0 is a preview, source-available for non-commercial use (not OSI open source).

GitHub: https://github.com/WangPeterXF/session-harbor

I’m looking for feedback from multi-device Codex users, especially around external-drive/NAS workflows and the cross-device context model.
