RepoLens
Add to Chrome
Chrome extension for evaluating open-source dependencies

Read code before
you trust it.

One click turns any GitHub, GitLab, npm, or PyPI page into a plain-English, verdict-first briefing — what it is, whether it fits, and how it’s actually built. Not the README’s pitch. The real shape of the thing.

Verdict before the README pitch.

Maintained, testable, permissive license. Watch dependency churn before adopting.

  • Risk: dependency drift
The verdict

It opens with the verdict, not the pitch.

Stars tell you a project is popular. They don’t tell you whether it fits your problem. RepoLens leads with a fit call and a one-line bottom line — then lets you go as deep as you want.

  • A fit call first — strong, solid, care, or risky — before a word of prose.
  • Measured, not trusted — health, languages, flags, and tech stack pulled from the source.
  • Deep on demand — ELI5, lineage, alternatives, and a Feynman-style explanation one click away.

The case file

The dependency decision workflow.

Fewer moving parts up front: scan a package, read the evidence, compare alternatives, and keep the whole evaluation local/private.

Scan the dependency page

Open a GitHub, GitLab, npm, or PyPI page and get a verdict-first briefing: fit, risk, maintenance, license, and the bottom line.

Read the evidence

Deep Dive explains the actual shape of the project — files, dependency graph, tests, lineage, and plain-English reasoning.

evidencedeep dive

Triage the shortlist

Every scan lands in a sortable library with boards, evaluations, drift alerts, and keyboard-first decisions.

libraryboards

Compare alternatives

Put candidates side-by-side, search GitHub for peers, and export the reasoning to CSV or Markdown.

Keep it local/private

Bring your own keys, route scans across 20+ providers, or run local Ollama. No server account required.

The procedure

Three seconds from page to verdict.

  1. 01

    Land on any repo

    GitHub, GitLab, an npm package, a PyPI project. Wherever you’re evaluating, RepoLens is one icon away.

  2. 02

    Click once

    It reads the source and runs it past the AI provider of your choice. The optional runner grounds it in measured facts — never executes repo code.

  3. 03

    Get the verdict

    A fit call, health, deep dive, and red flags — opened in a tab and saved to your local library to sort, compare, and revisit.

Models & privacy

Bring your own model. Keep your own data.

Route the verdict to a fast model and the deep dive to a strong one, with smart fallback. Twenty-plus providers behind one registry — any OpenAI- or Anthropic-compatible endpoint just works.

Stop trusting the README.

Install RepoLens, point it at the next dependency you’re weighing, and read the real shape of the thing — in plain English, in seconds.
