BangBang tests speed, security, SEO, accessibility and broken pages in one go, on phones and desktops. You get a clear report of what to fix first.
Pages open in a real Chromium browser at phone, tablet and desktop viewport sizes, with the cookie banner accepted first. Tap a card to see what is inside.
Lab Core Web Vitals from one page load on emulated phone and desktop viewports, plus a Lighthouse run on our server (its scores differ from PageSpeed Insights).
Passive checks, not a penetration test: missing security headers, weak TLS, exposed files and leaked secrets.
Titles, descriptions, canonicals, headings and indexability on every page.
Automated checks with axe-core against WCAG 2.0 to 2.2 rules. Automated tools find only part of the issues, so a manual review is still needed.
Your pages in emulated phone, tablet and desktop viewports (Chromium, not real devices or Safari), with a screenshot of each.
HTTP status codes, broken links, console errors and failed requests.
Compare staging with production, or this week with last week.
A full API for your own tools: start checks and read results from scripts and CI.
Type the address and press Check. No installation and no access to your server needed.
We find your main pages and open them in Chromium at phone and desktop sizes, like your visitors would.
Scores, the issues ranked by impact, and how to fix each one. Share the report with your developer in one link.
Sign up and your checks are saved. Run the same site again and BangBang shows you what got better and what got worse.
Every check of every site, with scores over time.
New issues, fixed issues and score changes, side by side.
Daily or weekly checks, with email, Slack or Teams alerts when something breaks.
Send a report link, with a password if you like.
Yes. The free check only does what a visitor's browser does: it opens a handful of your public pages. It does not log in, submit forms or try to attack anything.
The free check looks at up to 5 of your main pages on a phone and a desktop viewport. With an account you can check up to hundreds of pages, more devices and more test types.
No. You get 3 free checks a day without one. A free account keeps your reports, lets you compare them over time and removes the daily limit for your own sites.
Yes. Matter Solutions staff and clients with a Spartan account can use "Continue with Spartan". Everyone else can sign up with an email and password.
Yes. Everything is available through a REST API with keys, webhooks and a GitHub Actions step. See the API docs.
