Post Description

I got tired of having to pull, build and manually QA the gazillion PRs that Claude creates for me, so I built this tool that solves some of this pain.

GitGlimpse is an open-source Github action that acts as a visual reviewer. It looks at the diff, generates a visual demo and posts it as a GIF directly on your PR.

Current status - early beta:

- Optimized for single entrypoint repos - Best for small/medium sized projects

Would love to hear your thoughts/feedback/comments!

Treliq – PR triage CLI with 20 signals and optional LLM scoring

Deduping PRs and scoring them with 20 heuristic signals is a concrete, useful idea — especially the scope-coherence signal and embedding auto-fallback for providers without embeddings. The repo supports CLI, a persistent server, GitHub App integration and an explicit --model flag for provider flexibility, but it's still early and adoption/UX examples (ranked output, workflows) are thin — promising engineering scaffolding that needs real-world validation.
