opensource.to website review

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

1 long task block the main thread while loading, the longest for 55 ms. During a long task the page ignores taps.

1 third-party service load with your homepage (JSDelivr CDN), adding 10 KiB and 21 ms of main-thread time.

Polyfills for old browsers add 11 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

1 image could be 4 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.09 g of CO₂e: 11.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

16 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: 16 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Your title is 69 characters, so Google will cut it off around 60: “OpenSource alternatives to enterprise applications and SaaS solutions”.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is only 69 characters: “OpenSource.to is a platform for open source projects and communities.”. 70 to 160 characters is enough to sell the click.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://opensource.to/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at opensource.to/robots.txt, the first file search crawlers ask for.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 39 pages on opensource.to and 2 external pages.

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.

There is no /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.

/, /under-development and /submit-project all use the title “OpenSource alternatives to enterprise applications and SaaS solutions”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/under-development and /submit-project use the same meta description. A description written for each page earns more clicks.

/under-development and /submit-project have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 20 found) and read each the way a search engine does.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

opensource.to has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

opensource.to's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Social proof on the homepage: 2 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 424 words of visible text.

DMARC is set to p=none, so mail pretending to be opensource.to is still delivered. Add a report address, check the reports, then move to quarantine.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

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.

Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
