About Flask

webatla tracks 11,088 live websites using Flask, 0.0% of every site we index. Download the full list of websites that use Flask as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

Flask is a lightweight and flexible Python web framework designed for building web applications and APIs quickly. It follows a minimalist philosophy, providing the core tools needed for web development while leaving architectural decisions to the developer.

Created by Armin Ronacher and first released in 2010, Flask is part of the Pallets Projects open-source collection. It is one of the most popular Python web frameworks, widely used for prototyping, microservices, REST APIs, and full web applications. Flask's extensibility is a key strength — developers can add functionality through a rich ecosystem of extensions for databases, authentication, form handling, and more. It is a first choice for Python developers who prefer flexibility over convention.

When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above.

Which websites are using Flask?

webatla detects every site using Flask and exports them as one downloadable list, so you can see who relies on this technology and what else runs alongside it.

Open the Flask technology dataset to break adoption down by country and TLD, compare it with a competing technology, and track new domains over time.

Frequently asked questions

How many websites use Flask?

webatla detects Flask on 11K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Flask?

Yes, as structured JSONL. Grab a free sample first.

What's included for each site, and how fresh is it?

Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily.

How do I find the websites using Flask?

Buy the technology dataset, then download the complete list of domains we detect using Flask, re-exported every day.

What else is in the Flask technology data?

Each row places Flask next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.

Can I download just the sites using Flask, or the whole database?

Both. Every site running Flask comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export.

How do I download the list of websites using Flask?

Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running Flask as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank.
