# Unlighthouse review (2026): is it any good?

> Free open-source tool that runs Lighthouse on every page of a site

Checked Oct 23, 2026 · graded Oct 23, 2026 by ToolGPA.

Unlighthouse is a free, MIT-licensed command-line tool that finds the pages of a site from its sitemap, route files or by crawling links, runs Google Lighthouse on each one in parallel, and shows the results together in a local dashboard. A CI version fails a build when scores drop below a budget, and the v1 beta adds an MCP server for AI agents.

## Key features

- **Site-wide Lighthouse scans:** Runs Lighthouse on every discovered page using a pool of Chrome instances in parallel, with mobile and desktop results kept separately.
- **URL discovery:** Finds pages through robots.txt and sitemap.xml, your framework's route files, or by crawling links from the homepage; URLs can also be listed by hand.
- **Dashboard and scan history:** Results appear in a real-time dashboard in your browser, and saved scans can be reopened without scanning again.
- **CI budgets and reports:** The unlighthouse-ci command fails a build when any page scores below a budget and exports JSON, CSV or a static HTML report.
- **MCP for AI agents:** In the v1 beta, an AI agent can connect over MCP to run scans and read the results.

## Good for

- Developers who want Lighthouse scores for a whole site, not one page
- Adding a Lighthouse score budget to a CI pipeline
- Nuxt, Vite and webpack projects that want audits during development

## Worth knowing

- It runs on your own computer or CI and needs Node.js and Chrome; there is no hosted version.
- Results are Lighthouse lab scores only, with no real-user monitoring.
- Docker support is described as community-maintained and experimental.
- Version 1 is still in beta.

## ToolGPA grades

**GPA: 2.6 out of 4**, graded Oct 23, 2026. Unlighthouse finds every page of a site from its sitemap, routes or links, runs Lighthouse on each in parallel and shows the results in one local dashboard. But it needs Node.js and Chrome on your own machine or CI, there's no hosted version, the scores are lab only, and version 1 is still in beta.

- **Value for money: A.** Free and MIT licensed, funded by community sponsors. It runs on your own computer or CI, so there's no server to rent for a scan.
- **Free plan and trial: A.** Everything is free: the CLI, the CI runner and the dashboard, with no account and no limits on record.
- **Features: C.** Site-wide Lighthouse scans with URL discovery, mobile and desktop results, saved scans, CI budgets with JSON, CSV or HTML reports, and MCP in the v1 beta. It does that job fully, but it's Lighthouse lab scores only, with no real-user data.
- **Ease of use: D.** A command-line tool that needs Node.js and Chrome installed. One command starts a scan and the dashboard opens in your browser, but there's no way to use it without a terminal.
- **Platforms and integrations: C.** Runs on Mac, Windows and Linux, with Nuxt, Vite, webpack, GitHub Actions, GitLab CI, CircleCI and Puppeteer. A program for computers only, with no hosted version.

## Keep it, or make your own?

**Keep it.** Unlighthouse is free, so making your own would save you nothing. And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.6 is higher than 56 of the 83 other technical SEO tools we grade.

- You could not: Speed tests run from real browsers on a schedule.
- You could not: A crawler that checks every page of a site.
- You could not: Apps for macOS, Windows and Linux that stay in step with each other.
- You could not: It plugs into other products, Nuxt, Vite and webpack among them.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.
