I built a local AI code review dashboard because no one reviews my code

I'm a solo developer. I work on multiple projects, ship code daily, and nobody reviews any of it.
I looked at existing AI code review tools. They all had the same problems:

Need API keys (pay per token)
Send your code to external servers
Require org-level GitHub setup
Need accounts, onboarding, configuration

Meanwhile, I'm already paying for Claude Pro. I have Ollama running locally. These tools sit there unused while I push unreviewed code.

So I built CodeLens.

What it is

A self-hosted dashboard that watches your local git repos, auto-detects whatever AI CLIs you have installed, and runs automated code reviews. No API keys. Fully local with Ollama, or use your existing cloud AI subscriptions directly without a middleman.

How it works

Start the app (npm run dev)
Add a repo by browsing to its folder
CodeLens auto-detects your installed AI tools (Claude Code, Ollama, Gemini, OpenAI)
It immediately reviews the last 30 days of commits
Going forward, it polls every 60 seconds for new commits

The review page

This is the core of the product. Three panels:

Left: list of findings. Severity dots, category, file path. Click one to select it.
Centre: the actual code diff with line numbers. Green additions, red removals. Coloured dots mark lines with issues.
Right: full description, suggested fix, and a ready-to-paste prompt for your AI chat.

The idea is: CodeLens finds the bug, tells you what's wrong, and gives you a prompt to paste into Claude/ChatGPT to fix it. For vibe coders, it's copy-paste-done.

Features I didn't plan but ended up building

Deep review: scans your entire codebase, not just the latest commit. Good for auditing a project you inherited.
Fix tracking: when a new commit modifies a file and the AI no longer flags the same issue, the old finding automatically gets marked as "fixed."
Export as Markdown: download any review as a formatted .md file. Useful for PRs or client documentation.
500 fun loading messages: "Judging your variable names," "Wrestling with regex," "Questioning life choices." They rotate with pastel colours while the review runs.
Notification bell: tracks all review completions across repos with unread counts.

The self-review

The most satisfying moment was pointing CodeLens at its own repo. It found real bugs:

A full table scan loading every finding into memory
Timer leaks in the provider adapters (setTimeout never cleared on success)
A path traversal vulnerability in AI-generated file paths
A race condition where two concurrent review triggers could create duplicate records
Silent error swallowing that hid database failures

I fixed every finding it reported. Then it reviewed those fixes and found more issues. We went through 5 rounds before it converged to only info-level style suggestions.
