YOURLS, short for Your Own URL Shortener, is a self-hosted open-source URL shortener written in PHP and released under the MIT license. It runs on an ordinary web server with a MySQL or MariaDB database and serves short links on a domain of the operator's choosing, either privately for one person or team or publicly for anyone. Links are created and edited in a web admin interface, through bookmarklets or through an API that returns JSON or XML. For each link, YOURLS records clicks over time, referring sites and the visitors' countries. A plugin system with a large catalogue of community extensions adds features such as additional authentication methods, spam protection and custom redirects.

Shlink is a self-hosted open-source URL shortener written in PHP and released under the MIT license. It has been developed since 2016, mainly by Alejandro Celaya from Spain. Rather than being a hosted service, it runs on the user's own server, for example from the official Docker image, and serves short links on one or more of the user's own domains. Links are managed through a REST API, a command-line tool or the separate open-source Shlink web client, and they can be edited, tagged, limited in time or number of visits and redirected differently depending on the visitor's device. Every visit is recorded with details such as referrer and browser, and an optional GeoLite2 database adds the visitor's approximate location. QR codes can be generated for any short link.

Nemorius is a URL shortener from Paris, France, that was previously known as LC.CX and has been creating short links since 2009. Short links run on the lc.cx domain or, after a simple DNS change, on the customer's own domain. Besides shortening links, the platform creates QR codes, simple landing pages and forms whose responses can be viewed and exported from a dashboard. Audience reports show how links and QR codes perform in campaigns, and scheduled reports and link monitoring are available for larger teams. An API and integrations with production and project management tools allow links and QR codes to be created in bulk.

URLR is a URL shortener from Orléans, France, that has been developed since 2019 and is aimed mainly at companies and public organizations. Short links run either on the urlr.me domain or on a domain or subdomain that the customer already owns. Links can be edited after creation, organized in folders, protected with a password, given an expiry date or routed by visitor location. The service also generates QR codes whose destination can be changed later without printing a new code. A central dashboard shows visits, unique visitors and the split between clicks and QR scans over time. A REST API, webhooks and integrations such as Zapier allow links to be created automatically, and the interface is available in six languages.

Cuttly is a URL shortener from Gdańsk, Poland, that turns long web addresses into short links on the cutt.ly domain or on a customer's own branded domain. Every link records clicks with breakdowns by location, device, operating system, browser and referring site. Links can carry custom slugs, UTM parameters, passwords, expiry dates and device-specific redirects, and their destination can be changed after publication. Alongside shortening, the service creates QR codes, link-in-bio pages, simple surveys and call-to-action pages. Teams can share workspaces, and a REST API plus integrations with automation tools such as Zapier and Make let links be created programmatically.

Varnish CDN is a managed content delivery network (CDN) service from Sweden for websites, online shops, and APIs. It uses Varnish Enterprise to cache content at the network edge and reduce requests to the origin server. A browser dashboard lets teams configure caching rules, headers, cookies, and query parameters without writing Varnish Configuration Language code. Content can be purged through the dashboard or API, including by tag. The service supports managed TLS certificates, image optimization, WebSocket proxying, and configurable web application firewall and bot protection features. When an origin server becomes unavailable, it can continue serving cached content using grace mode.

CDN77 provides content delivery network (CDN) services for media companies, online shops, web applications, and software distribution. It caches and delivers website assets and files through a global network, and supports live streaming and video on demand. Multilayer caching and request collapsing reduce repeated requests to origin servers. Customers can manage CDN resources through a web control panel or REST API, with configurable caching rules, traffic statistics, and content protection features. The service is operated by UK-based DataCamp Limited, whose controlling holding company, Overkill Alpha, is based in Czechia.

dmarced is a DMARC monitoring tool from the Luxembourgish software company wierk. It receives the aggregate reports that mailbox providers send about a domain, evaluates them, and shows which services send email on its behalf and whether those messages pass SPF and DKIM authentication. Organizations can use this visibility to distinguish legitimate senders from spoofed ones and to tighten their DMARC policy step by step until receiving servers reject unauthorized email. Reported IP addresses are enriched with hostnames, countries, and network information so that sending sources are easier to identify. The same data is available through a REST API, which lets teams integrate domain checks and reporting into their own tools. Domains can be compared, followed over time, and summarized in weekly email updates.

DMARCTrust is a DMARC monitoring tool that receives the aggregate reports for a domain, processes them and visualizes which sources send mail and how they pass authentication. Paid plans add failure reports, TLS-RPT monitoring, alerts for DNS changes, API keys and data export. Customers choose at signup whether their data is stored and processed in an EU or a US region. The service also offers free helper tools such as a DMARC record generator and domain checks. It is operated by the French company FLGXPL, a one-person business in Paris.

Mailhardener is a DMARC monitoring tool that aggregates the reports mail servers send about a domain and guides its owner through the setup of email authentication. It covers SPF, DKIM and DMARC and adds SMTP TLS reporting, hosting of MTA-STS policies and BIMI assets, and monitoring of DNS changes. The dashboard shows which sources send mail for the domain and how they perform in authentication checks over time. A multi-tenant package is available for managed service providers that handle many customer domains. Mailhardener is developed by Mailhardener B.V. in The Hague in the Netherlands.

DMARCwise is a DMARC monitoring tool that collects aggregate reports for a domain and turns them into a web dashboard with weekly summaries. It also handles SPF and DKIM diagnostics, SMTP TLS reporting and MTA-STS. DMARC records can be hosted by the service through a CNAME delegation, so policy changes are made in the dashboard instead of at the DNS provider. Teams can work together in an organization, and a REST API and single sign-on are available in higher plans. Managed service providers and agencies can handle many customer domains from one account. DMARCwise is an independent small business based in Italy.
