DoUrl is a temporary short-link service introduced on a Portuguese-language page, positioned as a “fast and private” URL shortener. It lets users create short links either on the web or via API, with links automatically expiring within 1 to 7 days. The service explicitly emphasizes no registration, no click tracking, and no cookies, making it suitable for temporary sharing scenarios where you do not want to leave long-term link traces behind.
From a developer-tools perspective, DoUrl’s main value is its very simple HTTP API. Developers can send JSON to POST /api/shorten, with request fields including the required url and optional expires_in_days. The API requires no authentication, supports CORS, and can be called directly from web pages, scripts, or backend tools. The documentation provides examples for cURL, JavaScript fetch, Python, and PHP, and lists responses such as 201, 400, 405, 429, and 503, making it relatively clear. In terms of restrictions, it only accepts http:// or https:// URLs, supports URLs up to 2048 characters, does not allow shortening DoUrl’s own domain, and uses 7-character short codes made up of lowercase letters and numbers.
DoUrl’s page says the service is free, with Buy Me a Coffee and Sponsor options available to support the project’s operation. No formal paid plans, enterprise version, or SLA were found. The API rate limit is 60 requests per IP per hour; successful responses return the remaining request count, while exceeding the limit returns a 429 status and a retry time. Links are automatically deleted after a maximum of 7 days, so it is not a replacement for long-term link management or marketing analytics platforms.
The advantages are its extremely low barrier to entry, no account requirement, simple API, and clear privacy-first positioning, making it especially suitable for one-off or short-cycle link sharing. The drawbacks are also clear: there are no advanced features such as click analytics, custom domains, team management, or access control; open source availability, self-hosting, and official SDKs are not disclosed; and the service is provided “as is” under its terms, with no uptime guarantee.
DoUrl is suitable for individual developers, makers of small tools, temporary campaign pages, automation scripts, and privacy-sensitive short-term link distribution. If you need long-term stability, observability, and branded short links, alternatives such as Bitly, Short.io, Dub, and YOURLS may be worth considering. The source text does not provide information about access from mainland China, so actual network connectivity and the availability of payment or sponsorship methods need to be tested independently.
