Speed
Use efficient cache lifetimes
1.1 s · 333 KiB34 files are served with short cache lifetimes, so returning visitors download them again (333 KiB).
Reduce unused JavaScript
354 KiBAbout 354 KiB of JavaScript is downloaded but never used on this page.
Improve image delivery
150 ms · 17 KiB1 image could be 17 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.
Render-blocking requests
150 ms1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.
Minify JavaScript
134 KiB134 KiB could be saved by minifying JavaScript.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 95 ms. During a long task the page ignores taps.
1 third-party service on the page
1 third-party service load with your homepage (Other Google APIs/SDKs), adding 42 KiB and 24 ms of main-thread time.
Legacy JavaScript
10 KiBPolyfills for old browsers add 10 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Server response: 2 ms
2 msYour server sent the HTML in 2 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Images and page weight
About 0.2 g of CO₂ per visit
0.16 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.16 g of CO₂e: 19.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
4 checks passed
Page weight: 573 KiB in 48 requests
573 KiBYour homepage downloads 573 KiB in 48 requests on a phone: scripts 357 KiB (21), other files 108 KiB (9) and fonts 46 KiB (1). That is a lean page.
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
2 text elements with low contrast
2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
All page content should be contained by landmarks (61 elements)
All page content should be contained by landmarks: 61 elements on the page fail this check, rated moderate by axe-core.
1 form field without a label
1 form field has no label, so screen readers announce an empty box and autofill guesses.
Elements with visible text labels do not have matching accessible names.
Elements with visible text labels do not have matching accessible names. (2 elements).
2 checks passed
Every image has alt text
All 13 images in the HTML carry an alt attribute.
43 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 45 WCAG 2.2 A/AA and best-practice rules on the phone render: 43 passed and 2 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Title is short (29 characters)
Your title is only 29 characters: “React & Firebase SaaS starter”. Between 30 and 65 characters leaves room to say what you do and for whom.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
Meta description is long (166 characters)
Your meta description is 166 characters; Google truncates after about 160, so the end of your pitch is cut.
No XML sitemap
No XML sitemap at https://reactapp.dev/sitemap.xml, so Google discovers your pages only by following links.
11 internal links, 2 external
The homepage links to 11 pages on reactapp.dev and 2 external pages.
3 checks passed
One H1 headline
Your main headline reads: “Launch your next SaaS in minutes with our full-stack solution”.
Open Graph tags complete
Open Graph tags are complete, so shared links show a title, description and image.
robots.txt in place
robots.txt is in place.
AI search readiness
No Organization structured data
There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.
No llms.txt
There is no https://reactapp.dev/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.
2 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Text is in the HTML
Your server sends the page's text in the HTML (982 words), so crawlers that don't run JavaScript still read it.
Other pages
5 pages share a title
/, https://reactapp.dev/legal, https://reactapp.dev/privacy, https://reactapp.dev/changelog and https://reactapp.dev/license all use the title “React & Firebase SaaS starter”. Search engines can't tell which page to show for a search, so each competes with the others.
4 pages share a meta description
https://reactapp.dev/legal, https://reactapp.dev/privacy, https://reactapp.dev/changelog and https://reactapp.dev/license use the same meta description. A description written for each page earns more clicks.

Mobile viewport set
The page declares a mobile viewport.
Content and conversion
Thin social proof
Social proof on the homepage: 2 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.
No analytics detected

The homepage carries about 999 words of visible text.
5 checks passed

Direct contact links

Risk reducer mentioned
A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.
Privacy and tracking
No consent tool detected
No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
2 other companies contacted
Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at reactapp.dev, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
