    Bitly Review - Amazing Experience.

    Bitly is a URL shortening service and a link management platform. The company Bitly, Inc., was established in 2008. It is privately held and based in New York City. Bitly shortens 600 million links per month, for social networking, SMS, and email. Bitly makes money by charging for access to aggregate data created because of many people using the shortened URLs.

    The Bitly URL shortening service became popular on Twitter after it became the default URL shortening service on the website on May 6, 2009. It was subsequently replaced by Twitter's own t.co service.

    The company uses HTTP 301 redirects for its links. The shortcuts are intended to be permanent and cannot be changed once they are created. URLs that are shortened with the bitly service use the bit.ly domain or any other generic domain that the service offers.

Free Custom URL Shortener: Top Options in 2026
Bitly is one of the most recognized URL shorteners, but its free plan has become quite restrictive for anyone seeking a free custom URL shortener. You get only five short links per month, with three custom back-halves (the part after the slash). On the plus side, those five links can receive unlimited clicks, and Bitly provides click analytics.

FastAPI Reviews

    ยท Working at Kurslog ยท

    When our backend team needs to build services for data parsing, aggregators, or high-load APIs, FastAPI is our absolute go-to choice. It completely lives up to its name-development speed is outstanding.

    The combination of Pydantic for data validation and built-in async support keeps our shared codebase clean, strictly typed, and reliable. But the biggest highlight for our cross-functional team is the automatic generation of interactive OpenAPI (Swagger) documentation. Our frontend and mobile developers no longer have to wait for backend engineers to manually update API docs; everything stays perfectly in sync automatically. It has drastically improved our team's communication and delivery speed.
