One Tip a Week: Sniffly

This week’s tip of the week is Sniffly, created by Chip Huyen, a fellow GitHub Star.

I came across this tool after listening to a talk of hers recently. It’s a dashboard that ingests your Claude Code logs to provide insights to help you use Claude Code effectively. You get usage patterns, error breakdowns, and even a browsable message history you can share with teammates.

Why it’s handy:

• See how you actually use Claude Code over time so you can refine prompts and workflows.

• Spot common failure modes fast with the error breakdown view.

• Runs locally by default with no telemetry, so your code and chats stay on your machine.

• Drill into insights on a per-project basis to understand how different projects use Claude Code.

Quickstart:

via uvx:

uvx sniffly@latest init

via pip:

pip install sniffly
sniffly init

Then open the dashboard at http://localhost:8081. Note that you will need to have python installed on your machine.

Pair this with Anthropic’s own write-up on Claude Code best practices to turn insights into better day-to-day habits.

That’s it! Short and sweet. Until the next one!
