AI Analysis

●●SolidCozySolve My Problem

Uses your own Codex or Claude sub to avoid per-seat SaaS pricing.

Strengths
  • •Runs entirely on your own API keys, avoiding expensive enterprise SaaS contracts.
  • •Configurable review doctrine stored directly in the repo under .themis.
  • •No database or message broker required; runs as a single Docker image.
Weaknesses
  • •Relies on unstable CLI flags like 'claude -p' which may break without notice.
  • •In-memory job queue means reviews are lost if the container restarts.
Target Audience

Indie developers and small teams with existing AI subscriptions

Post Description

Hey HN,

I wasn't happy with the code review tools we use at work and on my side projects. Noisy, reviews in surface, expensive (overkill for sides). So since Gemini was getting sunsetted, I explored having my own.

As I am a cheap rat, this weekend I built Themis, that works with my Codex/Claude subscriptions (I understood "claude -p" is ok again in subscriptions).

I wanted it open-source so it can help other indie devs or small teams, self-hostable (or local), drawing from subs and mostly, configurable so it works well with your own repos.

No big ambitions nor 1 billion startup here, just fun (so please don't roast ahah). If it is useful to even a few people, that's already great.

Happy to have feedback (especially on distributing the app!)

Ps: 1st HN contrib, hope it's the right format
