WebExtension.org is a free extension-hosting platform with valid TLS and no threat detections, but its front page is currently behind a Cloudflare rate-limit error.
WebExtension.org presents itself as a free web hosting service for browser extensions and small developer projects, describing a migration from add0n.com and a mission to support developers and startups from a stated Toronto base since around 2010. The saved technical checks are clean: a valid encrypted connection and no browser threat feed threat warning. The main caveat is availability rather than security: the live page currently returns a Cloudflare 1015 rate-limiting error, and the platform states it does not control or take responsibility for the content individual developers host. There are no confirmed scam mechanics, no payment flow, and no independent reports of harm in the evidence, so the score sits in the low-risk band rather than Safe.

Why 78/100
Low Risk covers scores 70–84. 1 finding pulled the score down; 2 pushed it up.
What pulled the score down
- Moderate1 antivirus result marked the URL as suspicious. This comes from a saved antivirus observation rather than a new submission, so treat the detection as real but confirm the timing.
What pushed the score up
- SupportsThe saved TLS check found a valid encrypted connection and the browser threat feed returned no threat warning.
- SupportsThe registrable domain is 3356 days old, consistent with a long-running project.
No points per finding are stored for this report: our analysis weighed all findings together to set the score. Each finding shows its saved severity instead (Decisive, Strong, Moderate or Minor). Community reviews never change the Safety Score.

Investigation Brief
WebExtension.org presents itself as a free web hosting service for browser extensions and small developer projects, describing a migration from add0n.com and a mission to support developers and startups from a stated Toronto base since around 2010. The saved technical checks are clean: a valid encrypted connection and no browser threat feed threat warning. The main caveat is availability rather than security: the live page currently returns a Cloudflare 1015 rate-limiting error, and the platform states it does not control or take responsibility for the content individual developers host. There are no confirmed scam mechanics, no payment flow, and no independent reports of harm in the evidence, so the score sits in the low-risk band rather than Safe.
What the site actually is
The pages describe a free hosting service for browser extensions rather than a storefront. The site says add0n.com is being migrated to webextension.org and that developers can submit a support ticket to associate their extension with the new address. A separate passage frames the mission as helping developers and startups make their work available on the web, with a stated base in Toronto.
No purchase, checkout, wallet connection, or affiliate funnel appears in the reviewed content. The only commercial-adjacent link observed is a Mozilla Public License reference pointing to mozilla.org, which is a licensing pointer, not a paid relationship.
Operator and technical risk picture
The site is explicit that it is a host, not a publisher: it states the content of each page is provided by individual developers and that it exercises no control over, and accepts no responsibility for, user content. That is a normal disclaimer for a free hosting platform, and it is also the practical reason the operator cannot vouch for anything downloaded from a hosted extension page.
Technical signals are clean. The saved TLS check found a valid encrypted connection and the browser threat feed returned no threat warning. There is no evidence of malware, phishing, deceptive downloads, or payment abuse on this domain.
Current availability and visitor experience
The site is currently not usable from the sampled fetch: the visible page is a Cloudflare 1015 rate-limiting error for webextension.org, meaning visitors may hit an error page instead of content. This is an infrastructure and availability issue, not evidence of fraud.
The domain itself has a long registration history of more than nine years, which is consistent with a long-standing project rather than a throwaway domain, though age alone does not prove the safety of hosted material.
Why the score is 78
The saved checks found no material threat, but the evidence was not strong enough for the highest Safe tier. Coverage remains separate so missing sources cannot be mistaken for clean results.

Web research findings
Independent findings for webextension.org, including public complaints, named review sources, registration records, and look-alike-domain evidence. A missing result is shown as unverified, never converted into a clean bill of health.
No independently sourced scam reports or credibility records were found for webextension.org. That is common for new or low-traffic sites and does not clear the site.

Domain & infrastructure
The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

webextension.org has operated for years and this review found no material threat — a long track record, though it is never a guarantee on its own.
Contact Verification
Saved contact details can help identify the operator. Their presence supports traceability; it does not prove the business is trustworthy.
- Contact email on the site's own domain (advertising@webextension.org).
Domain & Encryption
Cloudflare DNS is used by legitimate and scam sites alike, so it does not identify who runs the site.
Certificate issued for webextension.org.
A shared Cloudflare address answers for many sites, so it is not the site's own server and says nothing about who runs it.

Payment providers the page loads
None seen among the outside domains we saved.
Read from the first 20 outside domains the page loads and the shop platform it uses; the web server and platform rows are under Hosting & Technology. A payment script on the page does not prove the shop accepts that method at checkout, or that you are protected.
